ina teak basket suspended from the roof of the warm 
Orchid House, if provided with abundant moisture in 
summer, and kept dry at the root in winter. This 
Stanhopea Mr. Rolfe thinks may be the lost species 
because under the hypochil of the lip there is a curious 
sac whose presence gives this organ a bigibbous appear- 
ance. This sac suggests greater affinity between our 
plant and the Peruvian S. graveolens, Lindl., than S. 
Wardii, Lodd., with which Reichenbach compared S. 
costaricensis, There are not many species of Stanhopea in 
Costa Rica, and there are few in the genus which have 
this sac. Either there are two species in Costa Rica 
with this sac, or our plant is identical with the Costa 
Rica Stanhopea flowered by Mr. Schiller at Hamburg 
in 1860. The original diagnosis does not mention the 
coloration or the dimensions of the flowers, and it is 
safest to identify provisionally the plant now figured 
with the one Reichenbach had in view. In our plant 
the sepals are buff-yellow with light red somewhat 
ring-like spots and with smaller spots on the petals 
and the lip, the latter organ having a pair of dark 
red ocular patches on the sides of the hypochil.
