A recent Peruvian collection (A/ug 3678) reterable to 
It. biloba differs from typical material in having a rela- 
tively elongate pseudobulb (up to 16 em. tall) bearing 
three leaves (instead of two) near the summit. The leaves 
vary greatly, the two lower blades being elliptic-oblong 
and up to 44 em. long and 7 ecm. wide, whereas the up- 
per leaf is narrow and about 80 cm. long and 3.4 cm. 
wide. ‘The scape is also short, about 35 cm. tall. 
Peru: San Martin: Zepelacio, near Moyobamba, at about 1100 
meters altitude, epiphyte in mountain forest, flowers brown, yellow, 
green and white, June, 1934, G. Klug 3678.

The concept Hriopsis Helenae appears to differ from 
Iv. sceptrum only in the larger size of its flowers. In these 
the sepals are described as about 2 cm. long, whereas 
those of 27. sceptrum seem to be 1.6 em. or less long in 
the drawing of its flowers from the original sketches in 
the Reichenbach Herbarium. In these drawings, the 
sinus between the lobes appears to vary from being acute- 
angled (as described) to being rounded (as in 27. Helenae). 
Although no mention of the vegetative parts of J. scep- 
frum appears in the description, the records of that spe- 
cies from the Reichenbach Herbarium show a cluster of 
roughly sketched elongate pseudobulbs similar to those 
of Iv. Helenae and they bear at the summit a pair of 
leaves which appear to be much shorter than those of J. 
Helenae. 
A recent Peruvian collection (Aluwg 1351) has flowers 
of apparently the same size as those of E. sceptrum with 
a rounded sinus between the lobes (as in #7. Helenae) and
