broadly truncate, 5 to 7 mm. long: corolla 3-fid, 1 cm. long; lobes 
obovate, rounded at apex, concave; labellum rotund, shortly 5-lobed, 
possessing a long claw. — Rio Asuncion, in damp woods along Juan 
Griego trail, Johnston, no. 298, Aug. 12-15, 1903. 
Elleanthus attenuatus, n. sp. Roots few, fleshy, fibrous, densely 
pubescent: stems 2 to 4, ascending, 6 to 9 dm. high, cylindrical; base 
covered with two or three sheathing leaves; lower stem naked or retain- 
ing the vaginas of old leaves; upper stem leafy: leaves glabrous, nar- 
rowly lanceolate, 15 to 20 em. long and 3 to 4 cm. wide, with 9 to Il 
veins, depressed above, plicate below, entire, long-acuminate; base cune- 
ate, constricted, broadening into vagina; sheath cleft anteriorly, about 
4.5 cm. long; uppermost leaves bractlike: inflorescence spicate, cylin- 
drical, elongate, about 7 cm. long; rachis puberulent; bracts slightly 
exceeding pedicel, about 1 cm. long, two-thirds the length of the flower, 
lanceolate to ovate, acute or acutish, reddish, striate: lateral sepals 
triangular, lanceolate, acuminate ; 1 posterior sepal narrowly lanceolate, 
acute: 2 lateral petals linear-lanceolate, acute, equalling other parts of 
perianth ; labellum broadly ovate, 1 em. long, obtuse ; margin crenate, 
with 2 elongated separate callosities at base: all parts of plant some- 
times minutely puberulent. — San Juan mt., in wet woods at the summit, 
alt. 640 m., Miller & Johnston, no. 270, July 30, 1901, and Johnston, 
no. 233, July 6, 1903. Allied to E. furfuraceus, Reichb. f., from 
which it differs in having larger, more attenuate, more ribbed leaves, and 
in its longer inflorescence. 
Epidendrum Johnstoni, Ames, n. sp. “ Plants 1 to 4 cm. high, 
diphyllous. Leaves narrowly elliptic-oblong, obtuse, sometimes stained 
or suffused with madder-purple, 2 to 4 cm. long, 6 to 10 mm. wide ; 
raceme terminal, lax, shorter than the leaves, 2 to 4-flowered, subtended 
by a conduplicate sheath, 5 to 10 mm. long; lateral sepals elliptic, 
subacute, 9 mm. long, 4.5 mm. wide, upper sepal similar; petals narrowly 
elliptic, obtuse, 8 mm. long, 2 mm. wide; lip adnate to the colump, 
8.5 mm. long, 3-lobed, lobes subequal, the lateral ones semicircular ; 
front of the column two erect callosities which converge obscurely in @ 
faintly tubercled hemispherical crest; column 4.5 mm. long, stained 
with madder-purple ; flowers apparently greenish-yellow, suffused with 
madder-purple. — San Juan mt., alt. 600 m., Johnston, no. 236, July 2, 
1903. Plants similar in habit to dwarf forms of E. conopseum, R. Br, 
to which species this one bears a slight resemblance. The main points 
of difference are in the hemispherical callous, in the length of the column, 
and in the broader segments of the perianth.”
