JBS (PDF/A 4767 KBytes) published online: March 19 2020 69(2b pp. 6) Guzmania bismarckii Rauh vs. Guzmania lindenii (Andre) Mez
Eric J. GoudaGuzmania bismarckii Rauh (1984a) was based on material found in 1980 near Riojain Moyobamba, Northern Peru. Rauh noted the material was closely related to G.lindenii (Andre) Mez (1896) and determined it ranked as a new species because itwas sufficiently different to G. lindenii plants he had seen in Oxapampa. My workshows that the Moyobamba material is closer to the type of G. lindenii than RauhâsOaxapampa plants are.See also Rauh (1984b), Moore (1995) and Bismarck (1997).Werner Rauh (1983) published pictures of plants he identified as Guzmania lindenii,collected in the Oxapampa area, that are showing a more divided inflorescencewith more slender (cylindric) spikes than shown in the so-called Morren Icon (fig. 1,Schlumbergeria lindeni (Andre) E.Morren 1883). Contrary to what Rauh wrote, thetype of Guzmania lindenii is also from N. Peru and not from the Oxapampa area andthe Morren icon is showing a plant that is more like the Moyobamba specimen (thetype of Guzmania bismarckii) than the Oxapampa one. I concluded that Guzmaniabismarckii Rauh should be considered a synonym of G. lindenii (Andre) Mez (1896).
JBS (PDF/A 502 KBytes) published online: February 21 2020 69(2a pp.10) Natural hybrids of Tillandsia argentina
Eric GoudaSome Tillandsia species easily form hybrids with other Tillandsia species and some likeTillandsia complanata Bentham (1846) even hybridize with species of other genera.Tillandsia argentina Wright (1907) is one that easily forms hybrids with other species.So probably there is a lack of physiological barriers between this and other species thatprobably did not occur in the past in the same distributional area. It is known thatunrelated Tillandsia species that do not grow in the same area can easily be crossedwith each other, because there are no physiological or biotic or abiotic barriers whichare needed to avoid hybridizing. As biotic factors you can think of pollinators thatdo not visit both species or different flowering time during the year, and as an abioticfactor different elevation.
JBS (PDF/A 329 KBytes) published online: January 21 2020 69(1) First description of the nocturnal flowers of
Cascante M. et al.First description of the nocturnal flowers of the little-knownWerauhia haberi (Tillandsioideae) and notes about its naturalhistory - Alfredo Cascante-Marin, Christian Trejos & Juan Francisco Morales - Flowers have a central role in sexual reproduction of higher plants and their morphology provides essential information for taxonomists. The ephemeral and delicate design of flowers often prevents their proper preservation in botanical specimens. Flowers lose their characteristic morphology after pressing and drying, reducing their utility for plant identification. The nocturnal behavior and short life-span of some flowers prevent collection of fully-opened flowers during day time when botanists usually perform their duties. Because of this, floral morphology of some rare and poorly collected bromeliad species has been scarcely documented and, in some cases, it is unknown at all. Knowledge of floral structure is relevant for the proper placement of species in its taxonomic group and in understanding the reproductive ecology and phylogenetic relationships.
JBS (PDF/A 1457 KBytes) published online: December 17 2019 68(4) 236-253 World Bromeliad Conference 2018, San Diego - Part 2
Juliana RaposoAfter a beautiful morning perusing the bromeliads at the show, we headed to the buses for our first garden tour. Our destination was San Diego's North County, home to some of the best gardens in town. First visited was Dan Kinnard and Eloise Lau's home in Vista. The couples house boasts unique organic architecture by James Hubbell and first-class art by the homeowners (Fig 34), all of which are worth the trek even for non-bromeliophyles. On arrival, a spread of Dan's yummy baked goodies was a treat one could not pass by (Fig. 35). In the garden, hardy terrestrials like Puya, Hechtia and Dyckia grow on the hillsides among fruit trees, while a spacious shadehouse hosts the more tender plants. Dan and Eloise have a beautiful all-around bromeliad collection, but I specially admire their billbergias.

Theresa M. Bert, Geoff Lawn, and Lyn WegnerAt each Bromeliad Society International (BSI) conference, the BSIs highest award, the Wally Berg Award of Excellence, is given to a specialist in bromeliads. The expert must be internationally renowned in at least four of seven areas specified in the call for nominations for the award (Bert, 2017). At the 2018 BSI World Conference, Eric Gouda received the award. In the bromeliad world, Eric has many professional achievements and has volunteered his time and expertise for more than three decades. Despite his busy work schedule, he has routinely assisted when needed, often at an international level. Erics areas of expertise include bromeliad ecology, taxonomy, culture, and identification. Eric is also skilled in developing and maintaining websites and in computer programming.

Bruce DunstanIn May 2018, I had the pleasure to travel with Carla Black and Angel Rodriguez to Nariño in south-west Colombia. Last year, we were in north-west Ecuador looking across the river into Colombia, wondering what might be growing there. This year we had a good look around and found some interesting plants. Nariño department has had its issues with security in the past few decades and travelling there hasnt been recommended. With the peace agreement now in place, times have changed and we had only positive experiences in the time we spent there.
JBS (PDF/A 386 KBytes) published online: December 17 2019 68(4) 202-205 Guzmania bicolor L.B.Sm. vs. Guzmania gracilior (Andre) Mez
Eric GoudaIn an earlier article (Gouda 2016) I mis-identified a background plant as Guzmania bicolor (Smith 1966). The plant in the background of figure 5 on page 203 of that article is actually G. gracilior (André) (Mez 1896). They are mainly distinguished by their leaf length and width, but there are some more differences. In the table below the two descriptions are compared with the important differences shown in bold.
JBS (PDF/A 311 KBytes) published online: December 17 2019 68(4) 196-201 Pitcairnia orchidifolia a nice, small and easy species worth growing
Eric GoudaPitcairnia orchidifolia Mez (1921) is an attractive not too large and easy to grow species for bromeliad collectors. It has a nice soft foliage and beautiful flower color, with petals that start out yellow, but become partly to fully red at anthesis (Fig. 1, see also Fig. 4). It seems to grow well under humid and shady conditions in cultivation. Leaves are very densely white lepidote on the lower surface only, contrasting with the glabrous upper side (Fig. 2). There is another name involved with this species, which is Pitcairnia grafii Rauh (Rauh 1988). Specimens of P. orchidifolia key out to P. platypetala in Smith & Downs (1974) - at least if you take the key to subgenus Pepinia. In the same work, P. orchidifolia is found in Key 2. under subgenus Pitcairnia, and possibly escaped Rauhs attention for that reason. Instead, Rauh compared P. grafii to P. platypetala in his original diagnosis. Distinguishing characters listed by Rauh for P. grafii are also found in specimens of P. orchidifolia so the two species are here treated as conspecific.

Graeme BarclayThe annual competitive show and major sale of the Bromeliad Society of New Zealand, known as the Fiesta, takes place in mid February each year in Auckland, the largest city in the North Island of New Zealand. In this year 2018, the dates were February 17th and 18th, with the usual city council War Memorial Hall in Mount Eden (a central city suburb) hired for three days. Friday was set-up day for the plant show, bromeliad display and sales tables, then the doors open to visitors from 9am to 3pm on both Saturday and Sunday.
JBS (PDF/A 2900 KBytes) published online: September 04 2019 68(3)105-168 World Bromeliad Conference 2018, San Diego - Part 1
Juliana RaposoMay 2018 - The World Bromeliad Conference 2018 was hosted by the San Diego Bromeliad Society (SDBS). This was the third WBC hosted by San Diego after hosting similar events in 1994 and 2006. Our logo (Fig. 1), featuring a Neoregelia, became a constant part of our lives during the months of preparation. The venue was Paradise Point, a tropical-themed island resort in the middle of San Diego Bay. A lush landscape, bay views (Fig. 2), and beautiful outdoor spaces set BSIs bi-annual gathering to a great start. All social functions and lectures were held in a great room facing the bay, and the large deck surrounding it was the perfect spot to mingle. The adjacent sales and show pavilion, a large tent-like structure, was bathed in natural light and ocean breezes (Fig. 3). There was plenty of room for vendors and show displays alike.

Dennis CathcartTillandsia fasciculata is a plant of stunning diversity with an impressive international range. Many, many differentlooking forms exist, some restricted to single habitats. Some forms are so widespread that one would be hard pressed to guess their country of origin. Not so the Floridian fasciculata. Any Tillandsia enthusiast could likely identify a plant from Florida. They are among the most beautiful and variable representatives of the species found anywhere ...
JBS (PDF/A 929 KBytes) published online: July 12 2019 68(3) Notes on the Androlepis Alliance, a lineage of Bromelioideae
Ramirez et al.Before the advent of DNA sequencing, classifications of plants in general, and of Bromeliaceae in particular, were primarily based on morphological characters observed in herbarium specimens (e.g. Smith & Downs, 1974, 1977, 1979). These classification systems were easy to use because they tended to be based on macroscopic features, such as shapes of floral bracts, sepals, and presence or absence of petal appendages. With the advance of methods for phylogenetic reconstruction and relying on different character sources, especially DNA sequences, we realize, that many of the groupings based solely upon conspicuous morphological features resulted in many artificial classifications, composed by species that do not share a recent common ancestors and have different evolutionary histories (what are known as non-monophyletic groups) (Faria et al., 2004; Schulte et al., 2005, 2009; Schulte & Zizka, 2008; Sass & Specht, 2010; Evans et al., 2015). It is well known that morphological similarities could result from different phenomena, such as evolutionary convergence, where identical or almost identical structures occur in species with different evolutionary histories. This phenomenon, which has probably taken place many times in bromeliads, coupled with the limited knowledge that we have about the origin of many structures used in the taxonomic classifications, are some of the problems that obscure our classifications based on monophyletic groups.
JBS (PDF/A 818 KBytes) published online: June 29 2019 68(3) A New Species of Racinaea (Tillandsioideae - Bromeliaceae) from Ecuador
Jose ManzanaresForestry engineer Nelson Jaramillo de Loja conducted his undergraduate researchon the emission of methane through bromeliad tanks at the San Francisco ResearchStation, Zamora Chinchipe, Ecuador. During the investigation he had the opportunityto study many bromeliads from the Scientific Station. When contacting me toidentify the species studied, I was struck by a species of Racinaea related to R. lutheriManzanares & Till and R. contorta (Mez) M.A.Spencer & L.B.Sm. After further study,the plant collected by Jaramillo, it turned out to be a new species that is presented andillustrated in the following article....
