this on to Dan Devor! .
decent type specimen is actually one of the most difficult tasks of a
botanist. There are lots of new species floating around but you need more
than a live plant which does not count for anything according to the
rules. It has to be herbarium material preserved in a recognized
herbarium. Moreover, I insist that the type be widely distributed,
meaning a bare minimum of three specimens, one on each continent. This is
to avoid the risk of losing or damaging the specimens by sending them through
the mail. Too often specimens, particularly those of large plants, are
collected in sets of one (useless in my opinion). When I collect and
suspect that something is new I try to make as many specimens as possible.
Naturally a good description is nice and commendable but legally there are no
demands on the quality of the description, unlike the demand that a collection
be preserved. I try to make excellent descriptions with lots of photos as
well. Aroids are confusing enough when you have excellent information so
it all helps.

Anthurium, sect. Belolonchium
Hi Daniel, I've been corresponding with Beth about this plant for some
time and will attempt to give you an answer. The type specimen needs to
be a plant with known collection data (elevation, forest type, epiphyte or
terrestrial) that has been fully described, ie, roots, stem, internodes,
cataphylls, blades, veins, inflorescence, infructescence and details on the
female and male flowers as well as pollen with detailed information on both the
adaxial (upper) surface as well as the abaxial (lower) surface of the blade
including the midrib, primary lateral veins and tertiary veins. The
people at the Quito
apparently did not collect field notes when they rescued their specimens which
were in danger of being destroyed so that data does not now exist. They
have given Beth an approximate location where it was found and Beth is now
working with Dr. Tom Croat to find it in the wild and do the necessary field
work to satisfy the publication of a scientific description of a new
species. The senior botanist also grants the plant its name. One
complete leaf must be dried and properly preserved so information can be
compared to other known species specimens. A dried blade may dry a
different color than known species or exhibit features not easily seen on a
living specimen, thus the need for the comparison. All that info plus the
dried specimen and a living specimen known as the "type specimen"
must be deposited in a recognized botanical garden collection. Of course,
Tom will do that work with Beth working as the junior co-author and the dried
material and type specimen deposited in the Missouri Botanical Garden
living collection of aroid species.
Genetic analysis is not normally done to publish a scientific
description. The new problem in botany is far too many genetic botanists
have little to zero idea what any species looks like in the wild state
including natural variations, they only know how to determine a species by
using genetic information which is virtually worthless to a field botanist such
as Dr. Croat. Field botany is regrettably a dieing breed of scientist!
If you are armed only with genetic data, how in the world do you know how to
recognize a plant in the wild? You can't easily do a genetic analysis in
the middle of an Ecuadorian rain forest.
Hope that helps.

Hi Beth, Perhaps you could explain to a total
novice who has never field collected plants what you mean by collecting the
"type specimen" and then showing us pictures of plants that are
already collected, flowering and fruiting (maybe I mesread and this is a
different plant)?? It seems the people at the Quito Botanical Gardens
could, if they chose to, compile a complete description of the plant in
question, including a proper genetic analysis if they deemed it
appropriate. Are you saying that all that is left to do is find the
original field notes for collection local?
Sorry for the naive questions, but I'm just curious

New Species Anthurium, sect. Belolonchium
Hi folks! As Steve said, I've found this big,
ornate-leafed Anthurium, which Dr. Croat says is undescribed, and for which I
am doing the fieldwork to collect the type specimen and take the environmental
data. He mentioned y'all might like to see it! I took a number of descriptive
photos of the specimens that are growing at the Quito Botanical Gardens, and
for ease of viewing they live in their own gallery. Here's the address:
I hope to find specimens with mature seed; if not I will have to take cuttings
in order to home-culture the plant. When I have viable seed for it, I'll post
another message for collectors. As a private citizen, it is very difficult for
me to ship live plant matter out of the country, but they have no problem with
Steve: I am not normally in the coastal forests, but it looks like I'll get an
opportunity to go later this month. I shall certainly keep an eye out for your
species, and if I find it I will take wild photos, and the observations you
wanted. I can also bug EcuaGenera on your behalf.
