NEW OR NOTEWORTHY ORCHIDS 
P. guatemalensis was distinguished from P. glandulosa 
in part by its shorter and less abrupt lip-claw. But judging 
from a Reichenbachian analysis on the type sheet of P. 
guatemalensis, such seems not to be the case. At any rate, 
this character is variable in Central American material. 
Moreover P. guatemalensis is said to have a smooth 
(not verrucose) lip, unlike its relatives. But this again is a 
variable character. It is indistinct in Floridian specimens; 
it is not mentioned by Fawcett & Rendle in the case of the 
Jamaican plants of P. glandulosa; but our Jamaican ma¬ 
terial shows this verrucose character to be more or less 
distinct. 
Finally Reichenbach claims that the ovaries of P. guate¬ 
malensis are much longer pedicelled than in P. glandulosa — 
a conclusion which again appears erroneous, judging from 
records of the type of P. guatemalensis in our herbarium. 
P. costaricensis is a good match for the Floridian Pon- 
thieva, except that its leaves, as described, are larger and 
the flowers also a little larger. However, another collection 
—Brenes 249 —determined by Schlechter as P. costaricensis — 
has even shorter leaves and smaller flowers than the type 
of this species. 
It seems advisable, therefore, to consider all these 
geographic forms as components of a single variable species 
which extends from Virginia to Florida (U. S. A.), through 
the West Indies, Mexico and Central America to Venezuela 
and Ecuador.
