My Pretoria Garden
Christo van Wijk
I am situated next to the Bronberg Mountain in Pretoria. The most severe frost
doesnt hit here, but rather settles closer to the highway that is about 400m from and
40m lower than me!
Winter temperatures are usually within the range of 2-23 °C (although we have
had freak cold spells with temperatures dipping to -4 °C), with the coldest period in
the two months of June and July. Minimum daily temperatures are encountered during
the hours between 1 and 4 am, and even during the coldest months are seldom below
10 °C when the sun is out. Summer temperatures are usually 18-42 °C....

Bromeliad Systematics - Stepping Back to move Forward
Gregory K. Brown
The taxonomic framework and understanding of diversity and relationships within
the Bromeliaceae is based on, and has been influenced by, the works and contributions
from scores of individuals over at least the past 300 years. These individuals include
explorer-collectors, horticulturists, hobbyists, naturalists, students, artists, professional
botanists, and other scientists. When considering this spectrum of contributions, with
special attention given to the many important ones (e.g., Linneaus, 1762; Baker 1889,
Rauh, 1979; Benzing, 2000; Givinish et al., 2007), I consider three sets of contributions,
Baker (1889), Mez (1896, 1935), and Smith & Downs (1974, 1977, 1979) to be
monumental milestones for Bromeliaceae Systematics. ....

Spots in Neoregelia
In several spotted hybrids, the spots
are large and bold. They also frequently
overlap, leading to splotches of color
with irregular borders - and often, no
hint of their circular origins.

A few Conference memories
I attended my first World Conference in 2008, in Cairns Australia, the first WBC
to be held outside the US. I had mentioned some months previously to a friend that
it was a dream of mine to attend a bromeliad world conference. She replied 'so why

2018 World Bromeliad Conference
Join us in San Diego, California for the 23rd
World Bromeliad Conference Fiesta de las
Bromelias, May 29 - June 3, 2018.
Planning for the 2018 conference is well underway. As a venue, we have secured
the fantastic bayside resort Paradise Point which is close to San Diego restaurants, parks,
attractions and the airport. We hope that you will plan on joining us for an exciting
bromeliad extravaganza. There are several bromeliad growers and nurseries within
striking distance, and there are both public and private gardens to see.

In Honour of Franz Georg Gruber (Part 1) In search of a very special bromeliad Goudaea ospinae var. gruberi Luther
Confused with the title? Thats because the new genus, Goudaea, was recently created
for a small group of Andean Vriesea species based on a phylogenetic analysis of
molecular (DNA) data followed by mapping newly reassessed morphological characters
onto the final trees. The two species are Goudaea ospinae and Goudaea chrysostachys,
including the recognised varieties in each. Considering what a typical Vriesea flower
looks like, think of Vriesea carinata or V. fosteriana, then its no wonder G. ospinae
and G. chrysostachys had to be moved into their own genus. They are quite unique and
more closely related to Cipuropsis amicorum and Zizkaea tuerkheimii, both ex-Vriesea as well!

A new species of Cipuropsis, and some remarks about this recently resurrected genus
Eric J. Gouda
Recently the genus Cipuropsis (Vrieseeae) was resurrected in the revision of the
Tillandsioideae by Barfuss et al. (2016) as a monotypic genus containing only the type
species, Cipuropsis subandina Ule (1907). No species were transferred to the genus by
Barfuss et al., mainly because this species could not be included in the study because
the type could not be investigated phylogenetically, it is not in cultivation and known
from the type collection and a few additional collections only.

Notes on the floral biology, seed morphology and post-seminal development of Vriesea minarum L.B.Sm., an endangered Bromeliaceae of Southeastern Brazil
Pâmela Lavor et al.
Vriesea minarum is a bromeliad endemic to the Iron Quadrangle region in Minas
Gerais state, Brazil and is currently listed as an endangered species. The aim of our
study was to investigate the species floral biology, breeding system, and post-seminal
development. Observations and experiments were conducted in the Rola-Moça
State Park. Flowers have morphological characteristics typical for the genus but we
discuss the position of the ovary, oversimplified in some papers as superior. Seed
set indicates that V. minarum is predominantly outcrossing, but self-compatible as
well. The floral biology indicates flower protandry, and suggests a mixed pollination
syndrome, as was observed recently in other bromeliads. Due to the survival risk facing
this species, we suggest that more studies investigating the potential to preserve
germplasm should be conducted, since its seeds appear to have a limited viability

The Search for Irish Bromeliads
Ireland is not a country
where you would ordinarily
expect to find many bromeliads.
When I recently told friends that
Calandra and I would be travelling
to Ireland and they asked
why?, my response was 'to look
for Irish bromeliads!' I wasnt
being serious about it of course
and certainly didnt expect to see
any tropical plants during our
visit, much less any bromeliads,
but it wasnt long after we arrived in Dublin before we spotted our first bromeliads.
A street corner vendor offering
cut flowers and potted plants
for sale included a tray of very
healthy looking, yellow blooming
guzmanias (see photo above)
in his wares - our first 'sighting',
although not particularly
