ligulate, 18-80 cm. long and 2-2.5 em. wide. The pe- 
duncle with the inflorescence is about 40 cm. long. The 
inflorescence is paniculate with the branches abbreviated. 
The pedicel and ovary are smooth. The sepals are ligu- 
late, narrowed toward both ends and the petals are nar- 
rowly oblanceolate. The lateral lobes of the lip are oblong 
and are separated from the orbicular-ovate mid-lobe by 
a short isthmus. The flowers are greenish yellow and the 
lip has purple markings. This form is suggestive of var. 
ramonense, but has the straight column of the species 
proper. 
EKnecycha Brenesu Schitr. of which the type is Brenes 
258 collected at San José de San Ramon, Costa Rica. 
From the description and the drawings sent to us by 
Dr. Schlechter, this species appears reducible to Hpiden- 
drum Mooreanum Rolfe. 
Eneycha Tonduziana Schitr. of which the type is 
A.& C. Brade 1274 collected at Cismo near San Jeroni- 
mo de Grecia, Costa Rica. From the description and the 
drawings sent tous by Dr. Schlechter, this species seems 
reducible to Mpidendrum Moorcanum Rolte though the 
lateral lobes of the lip approach the typical form in shape. 
A tabulated study of the available specimens of the 
various constituent species of the alliance (species former- 
ly believed to be distinct) brought out the following lines 
of separation: 
1. The presence or absence of lateral auricles on the 
column. These auricles are sometimes reduced to 
more or less developed teeth. 
2. The column more or less sharply reflexed in the mid- 
dle as opposed to the column straight. 
3. The shape of the petals and their breadth as com- 
pared with that of the sepals. 
4. The shape of the lateral lobes of the lip.
