it includes the concept which Lindley described as 1. 
spathaceum from fragments ‘‘obtained by Mr. Mathews 
out of the herbarium of Ruiz and Pavon, preserved at 
Lima.’’ The only difference between these two species 
appears to be that in /’. spathaceum there is no indication 
of leaves, whereas in 7. nutans Ruiz & Pav. there are 
oblong-lanceolate or elliptic-oblong obtuse leaves which 
are 14.5 to more than 16 em. long and 8—-8.5 em. wide. 
A Venezuelan specimen from Merida (A/fredo Jahn 
984), which represents this species, bears similar leaves 
up to 28 cm. long and 8.3 cm. wide. 
Epidendrum Ruizianum is thus recorded trom Vene- 
zuela, Colombia and Peru (type).

The original description of H’pidendrum scabrum is 
very brief and inadequate, merely saying: ‘‘E. foliis 
ovato-lanceolatis, marginibus vaginisque scabris, racemo 
terminali, nectari labio cruciformi. ”’ 
Fortunately, however, there is in the Ames Herbarium 
a photograph of the type of #7. scabrum from the Madrid 
Herbarium which shows the following characters. Stem 
(incomplete below) stout, leafy, apparently densely pus- 
tulose. Leaves numerous, distichous, horizontally spread- 
ing, with the internodes about 2 cm. long; lamina ovate- 
lanceolate or ovate-oblong, acute or short-acuminate, 
clasping at the broadly rounded base, up to 4.3 cm. long
