lateral lobes of the lip are represented as obliquely and 
broadly subquadrate from a cordate base. Therefore, they 
seem to be quite similar to those of typical 7. chaguense 
even though these structures are described as ligulate. 
The leaves are said to exceed 10 cm. in length, whereas 
they are represented in the drawing as 6 cm. or less long 
(like the leaves shown in FE. tbaguense and EL. radicans). 
As figured, the flowers appear to be of approximately the 
size and quite the same form as those of £. ibaguense, 
and are described as dark garnet-red with a yellow lip. 
The Venezuelan Hpidendrum laetum, of which I have 
seen a drawing and analysis of the type (made under the 
supervision of Dr. Schlechter), seems to be very close to 
typical H. ibaguense but with slightly larger bright pur- 
ple flowers. The lateral lobes of the lip are coarsely in- 
cised-dentate like those of the co-type of HH. decipiens 
from British Guiana. The claw of the mid-lobe is rather 
short, yet distinct. 
The Colombian 47, Baumannianum, represented also by 
a floral analysis made under the supervision of Schlechter, 
appears to be inseparable from 27. tbaguense. The leaves 
are somewhat larger, but the flowers (of which there are 
no color-notes) are almost identical with that species save 
that the sepals and petals are subobtuse and not acute 
nor acuminate. 
Epidendrum fraternum from Colombia, illustrated by 
a floral analysis made under the supervision of Schlechter, 
isasmall-leaved species having nearly the same floral seg- 
ments as some forms of J7. radicans. The lip which is 
‘rather shorter than that of HM. ibaguense has lacerate- 
dentate lateral lobes and the short subquadrate mid-lobe 
is little dilated at the apex. The presence of even this 
short claw on the mid-lobe inclines me to place this con- 
cept as asynonym of &. ibaguense rather than of its va- 
riety confluens. No color notes are given.
