TROPICAL AMERICAN ORCHIDS 
base of the middle lobe. Column slender, dilated above, 6.5 
mm. long; clinandrium entire. Pollinia irregularly compla- 
nate-cylindrical or complanate-pyriform. 
Vegetatively Epidendrum reflexum resembles E. piesto- 
caulos Schltr.; in floral structure it is allied to E. Turialvae 
Reichb. f. 
The name “reflexum” is in allusion to the perianth seg¬ 
ments.

Elleanthus tricallosus A. & S. sp. nov. Herba epi- 
phytica, caulibus simplicibus. Folia disticha, ascendentia, 
anguste lanceolata, longe acuminata. Racemi terminales, 
breves, pauciflori. Sepala ovato-oblonga, acuta, lateralia 
obliqua, apice carinata. Petala subspathulato-linearia, apice 
rotundata. Labellum basi saccatum, sacco bicalloso; pars 
anterior major, suborbicularis, margine lacero emarginata, 
basi callo transverso bidentato finita. 
Plant epiphytic, 29-32 cm. or more tall including the 
erect-spreading leaves (stem often broken off below). Roots 
fibrous, flexuous, glabrous. Stems caespitose, slender, 1-1.5 
mm. in diameter, mostly concealed by close striate-nervose 
sheaths. Leaves narrowly lanceolate, 4.4-13 cm. long, 7-13 
mm. wide below the middle (the uppermost and lower leaves 
shorter), long-acuminate to the sharp unequally 3-toothed 
apex, the central tooth long-extended, cuneate-narrowed to 
a sessile base, rigid, plicate, many-nerved with about five

flowered rather dense raceme. Floral bracts 1.8 cm. long or 
less (the upper successively smaller), strongly concave, em¬ 
bracing and surpassing the pedicellate ovary, broadly ovate 
when spread out, striate-nervose, rather abruptly acuminate 
with a rigid point, somewhat erose a little above the middle; 
the lowermost bract empty and abruptly terminated by a 
reduced leaf-blade. Rachis and ovaries black-pubescent. Lat¬ 
eral sepals obliquely ovate-oblong, about 8.5 mm. long, about
