have been seeking a specimen of the real Anthurium hookeri for
years! Before you immediately respond and say yes, please look at the
photos and read the
this thread. The majority of plants
sold in Florida are not the true species known to science as Anthurium
hookeri. but instead a plant using the name as a
common name. This plant appears to be far rarer than many of us
believe. It is found largely in the windward islands of the Caribbean
but also in French Guiana and other countries including Venezuela.
I've talked several times to Joep Moonen in French Guiana about it and
he sees it rarely.
to be able to
give a good reason why almost everyone in Florida thinks they are
hookeri in their yard when they are not. Well known IAS member and
aroid grower Denis
Rotolante in Homestead offered the best reason I have been able to
many nurserymen down here know, Anthurium hookeri is a catch all name
to all bird nest type Anthuriums regardless of true taxonomic origins."
Many of those hybrid plants sold in Florida appear to be more closely
schlechtendalii or Anthurium plowmanii than to Anthurium
you are growing Anthurium hookeri and your plant matches the
information in this thread I know for certain there are other growers
find it, including me!
shows a specimen of the true Anthurium hookeri photographed at
Missouri botanical Garden. Look closely at the leaves and veins.
distinctive characteristics of the true Anthurium hookeri is it does
produce red berries as is commonly believed on the internet and many
plant forums. The berries of the true species are
all the information on
the Internet stating the berries are red is inaccurate. I even found
one noted garden showing a photo of an infructescence with red
berries. The plant
referred to in all the garden site posts appears to be one of the
common plants sold in Florida using the
name only as a common name and not referring to the true species..
characteristic of Anthurium hookeri is the interprimary veins
are evenly spaced
similar to the rungs of a ladder. In
science this even spacing is known as the venation being scalariforme.
characteristic is a newly emerging leaf unfurls in a way that is not
other bird’s nest Anthurium species.
The unusual way the new leaves of Anthurium hookeri are
is known as being supervolute vernation and
are very unusual in most species. That term
indicates the new leaves possess coils
or folds in overlapping whorls.
Vernation refers to the arrangement of young leaf blades and
vernation is to possess a convolute arrangement in the folding or
of a newly emerging leaf blade with one margin (edge) of the newly
emerging rolled inward toward the midrib and the opposite margin rolled
the midrib o the opposite leaf f in a manner similar to the coil at the
a conch shell.
bird’s nest Anthurium, at least those that are members of Anthurium
section Pachyneurium, produce convolute new leaves. The
difference in supervolute and
convolute vernation is convolute vernation occurs when several leaves
with the next leaf in a module enclosed within the current leaf. I
is difficult to understand but look at the leaf in the photo as well as
diagram below. Look closely at the diagram of convolute vernation and
you will see the second leaf inside the first leaf which is common to
the way bird's nest forms unfurl. Anthurium hookeri is the
only exception according to Dr. Croat. Tom once indicated he felt
Anthurium hookeri could be in section Porphyrochitonium.
very important characteristic is the real Anthurium hookeri has
dots, especially on the underside of the leaves. In science these
dots are known as glandular punctates.
have real species of Anthurium hookeri please post photos and
know where specimens of your plant can be found please post that as
are several other unique characteristics found only on Anthurium
not on the hybrid or miss named plants commonly sold in Florida. If you
learn more the information can be read here:
scientific description of Anthurium hookeri is very simple; so
for anyone that
may doubt the accuracy of what I am trying to explain please take a few
to read the actual description.

I really want to
find this plant so thanks
very much for any help!
