Ornithidium nubigenum Reichenbach filius in Walpers 
Ann. 6 (1868) 488; in Linnaea 41 (1876) 85. 
The original and only prior collection of this species 
‘ame from Pamplona, Colombia, about 1200 or more 
miles from the Peruvian collections cited below and at 
the much greater altitude of about 8000 meters. 
Inasmuch as both of the descriptions of this concept 
are rather inadequate and give no reference to size, the 
following specific notes are now added. 
Plant large, sprawling, loosely branched, the stout 
stem being mostly concealed by tubular rugulose sheaths 
of which the upper ones are more or less separated and 
leaf-bearing. At intervals of 11 to 20 cm., (often in the 
angle formed by the branches) are short stout strobili- 
form stems, up to 6 cm. long, concealed by several pairs 
of closely imbricating distichous scarious-margined leaf- 
sheaths. Leaves linear, long-acuminate, slightly nar- 
rowed toward the base, more or less faleate, rigid, cori- 
aceous, appearing more or less convolute in the dried 
specimen, up to 80 cm. long and 1.1 em. wide. Inflores- 
cences numerous, abbreviated, 1-flowered, in the axils of 
the leaf-sheaths on the short strobiliform branches. 
Flowers small, deep pink to dark red, campanulate, with 
fleshy segments. Dorsal sepal oblong-ovate, acute, con- 
‘ave, about 7.5 mm. or less long, 8-8.7 mm. wide. Lat- 
eral sepals obliquely oblong-ovate, slightly smaller than 
the dorsal sepal. Petals oblong-elliptic, much smaller 
than the sepals. Lip much shorter than the sepals in 
natural position, sigmoid when viewed from the side, 
simple or nearly so, from a cuneate concave base gradu-
