NEW OR NOTEWORTHY ORCHIDS 
heavily and broadly thickened — on the outside — along 
the middle near the point of insertion, the lower half finely 
dotted with orange on the inside. Labellum 4 mm. long, 
2.5 mm. wide below the middle, very fleshy, ovate-lanceolate, i 
acute, with the tip laterally compressed, margins obliquely 
ascending. Disc traversed longitudinally by a prominent 
thickening which is decurrent from a large, laterally com- 
planate, fleshy, triangular, erect callus which is situated in 
the middle near the base of the labellum. Column fleshy, 
about 3 mm. long. 
In general aspect not unlike Notylia albida Klotzsch, but 
differing from it in the entirely free lateral sepals and fleshy 
flowers. 
Costa Rica, Rio Estella, C. H. Lankester & Alfredo 
Sancho 373. Common in open undergrowth near streams. 
Flowers aromatic, pungently spicy. (Type in Herb. Ames 
No. 24909.) 
Ornithocephalus hicornis Lindl. in Benth. Bot. Voy.

Ornithocephalus lanuginosus Ames in Proc. Biol. Soc.

Bindley, with unpardonable brevity, described this 
species as follows: “ folds ensiformibus erectis racemo 
hirsuto longioribus, sepalis subrotundis apiculatis petalisque 
conformibus unguiculatis ciliatis, labelli carnosi bipartiti 
laciniis lanceolatis recurvis canaliculatis. —■ Panama.” He 
omitted any reference to the canaliculate median appendage 
which is such a conspicuous part of the labellum. In his 
herbarium, however, he drew the labellum in detail and 
clearly showed this median appendage. Without the type 
specimen and Lindley’s drawing it would be quite simple to 
exclude 0. bicornis from contemplation in attempts to 
identify species of Ornithocephalus. From the synonymy 
given above it is evident that two species, which I now 
regard as inseparable from Lindley’s 0. bicornis, have been 
proposed recently. In proposing 0. diceras Schlechter 
wrote: At first I believed that 0. bicornis was before me.
