The type
specimen of L. nummularia was collected
by William Jameson around 1856, without
exact location. An examination of his collection
records shows that he collected his specimen
somewhere near Volcan Pichincha on the western
slopes of the Andes. Curiously, all modern
collections of L. nummularia are
from the EASTERN Andes. Some months ago
my orchidologist friend Lorena Endara gave
me some live Lepanthes that she
had collected in the western Andes; one
of these just flowered and proved to be
a form of L. nummularia! I call
it Form G. The lip is long, thin, straight,
and appressed to the column, somewhat different
from most of the eastern forms. The only
eastern form with a slightly similar lip
is Form A from Tapichalaca, but there are
significant differences. DNA analysis may
eventually show us that this form is the
same as Form A, but until then I shall tentatively
treat it as distinct. Los Cedros has a flora
very similar to that of Volcan Pichincha
(according to Lorena) and I suspect that
this is the form that Jameson collected.
This Form G thus probably deserves to be
known as the true L. nummlaria.
Thank you Lorena!
One of the Lepanthes
nummularia specimens Lorena collected
in the west has different leaves, but it
has not flowered and is near death. I will
use DNA analysis to see how it relates to
the other forms. |
