STUDIES IN STELIS. I.

OakES AMES 
IN PROPOSING a new Stelis of the ‘‘Stelis Liebmannii 
group’’, it should prove helpful if the allied species of 
Middle America are compared and clarified. ‘The first 
species of the group to be recognized was Stelis Lieb- 
mannit, published as a nomen nudum in the Gardeners’ 
Chronicle ser. 2, 12 (1879)108,and attributed by Hemsley 
to H.G. Reichenbach. I cannot discover any published 
description of Stelis Liebmannu. The specimen in Reich- 
enbach’s herbarium bearing this name is Liebmann’s no. 
168, collected in August in 1841 near Mirador, Mexico. 
It is a slender plant, about 14.5 em. tall, with narrow 
linear-oblong leaves 6-9 cm. long, with an average width 
of about 5 mm. The monophyllous secondary stems are 
very slender, ranging between two and three centimeters 
in length. The racemes are borne by distinctly flexuous 
almost filiform peduncles. The diminutive flowers, about 
twenty in number, on the evidence of dried specimens, 
appear to have been yellowish, perhaps faintly tinged 
with purple. The sepals, ovate in outline, are hardly 2 
mm. long. The labellum is minute, rather distinctly 
3-lobed, with the lateral lobes rounded and erect, and 
the terminal lobe narrowly triangular-cymbiform, with a 
sharply upturned acute tip. (The accompanying illustra- 
tion obviates the necessity of a moredetailed description. )
