ORCHIDACEAE QUAEDAM AMERICANAE 
(probably whitish or yellowish when alive, with scattered 
purplish dots); lateral lobes 3 mm. long, about 1 mm. wide, 
narrowly oblong, pointed, divaricate; middle lobe 5 mm. 
long, 5 mm. wide just below the tip, oblong at base, gradu¬ 
ally dilated and subelliptical above the middle, subtruncate 
at the tip. Disc between the lateral lobes ornamented with 
a large cushion-like callus from which three nerves extend 
forward, the middle one prominent near its base. Column 
5 mm. long, rather stout, obtusely lobed on each side at 
the summit. 
A very distinct species allied to Epidendrum virgatum 
Lindl., with which it has been confused, but from which 
it is distinct in having much longer leaves, a longer inflo¬ 
rescence, and a differently shaped labellum. 
In Folia Orchidacea (Epidendrum 13), underE. virgatum, 
Lindley cited a single collection, that of Hartweg from the 
mountains of Coban, Guatemala (erroneously localized 
in Mexico by Lindley). This specimen is conspecific with 
, E. icihyphyllum, and should not be confused with the type 
of E. virgatum, which is a Mexican species brought from the 
State of Oaxaca by Karwinski and preserved in the Herbaria 
of Martins and Zuccarini. In Lindley’s Herbarium at 
Kew there is a fragment of a Mexican specimen from Zuc¬ 
carini, which I take to be the true E. virgatum. This has 
the suborbicular or obovate mid-lobe of the labellum charac¬ 
teristic of all Mexican material I have examined. In ad¬ 
dition to the Zuccarini specimen there is, in Lindley’s 
Herbarium, a specimen collected by Jurgensen in Mexico 
which Lindley did not determine, but which Rolfe accepted 
as Epidendrum virgatum. 
Epidendrum virgatum, although variable in the shape 
of the labellum lobes, is usually well characterized by its 
vegetative parts, the pseudobulbs rarely exceeding 4 cm. in 
length, the leaves averaging about 20 cm. in length. In 1905 
I received from G. G. Pringle a number of living specimens 
of the species collected in Mexico, which flowered very 
freely in my greenhouses. The dried specimens prepared 
from this material show broader lateral lobes of the label¬ 
lum than are characteristic of the specimens in Lindley’s
