broadly truncate, 5 to 7 mm. long : corolla- 3-fitl, 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, G 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 cm. long and 3 to 4 cm. wide, with 9 to 11 

 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, cvlin- 

 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 linear4anceolate, acute, equalling other parts of 

 perianth ; labellum broadly ovate, 1 cm. 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 ^. fiirfiu-acens, Reiclib. f., from 

 which it differs in having larger, more attenuate, more ribbed leaves, and 

 in its longer inflorescence. 



Epidendrum Johnstoni, Ajies, 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 aduate to the column, 

 8.5 mm. long, 3-lobed, lobes subequal, the lateral ones semicircular ; in 

 front of the column two erect callosities which converge obscurely in a 

 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."
