rigid with a glossy wax-like appearance, 4-4.5 cm. long, 
complex in structure; basal half deep yellow with lines 
of purple flecks, subglobose-saccate, centrally lightly sul- 
cate beneath, verrucose-corrugated on the interior sur- 
face, very fleshy-thickened and deeply sulcate in front, 
2.3-2.8 cm. wide, 1.5—2 cm. deep,on each side provided 
with a short terete horn; horns incurved, adnate to and 
conforming with the basal margins of the upper half of 
the lip, the free part about 6 mm. long; upper half of lip 
flat, whitish, densely flecked with red, broadly rhombic- 
ovate, rounded-obtuse at the apex, lightly and broadly 
suleate, about 2 em. long and 2-2.5 cm. wide. Column 
fat, somewhat arcuate, lightly winged above, about 3.5 
em. long and 1.2 cm. wide above the middle. 
Stanhopea Lewisae is without close allies. It is distin- 
guished from all other species of Stanhopea by the ex- 
tremely short lateral horns on the lip which are terete 
and free for only about 6 mm. The rigid apical portion 
of the lip is also characteristic of this species. 
It is rather unusual to find anew species in such ashowy 
genus as Stanhopea. We take pleasure in naming this spe- 
cies in honor of its discoverer, Margaret Ward Lewis.
