two short lateral nerves, about 7.5 mm. long and 2.9 mm. 
wide. Lateral sepals similar, obliquely elliptic-lanceolate, 
complicate-acute, 2-nerved. Petals obliquely oblanceo- 
late-linear, subacute, glabrous or very sparingly ciliate, 
1-nerved, about 7.5 mm. long and 1 mm. wide. Lip 
fleshy, erect, tubular-concave, simple, about 10 mm. 
long, about 10 mm. wide when forcibly expanded, broad- 
ly rounded, minutely erose-fimbriate, dorsally minutely 
pustulose. Column clavate from a slender base, about 
5.5 mm. high. Ovary densely pubescent. 
This species appears to be allied to A/tensteinia longi- 
spicata C. Schweinf., but differs markedly in its small, 
relatively dwarf stature, short oblong-elliptic leaves and 
glabrous petals.

Cranichis calva (Kriinzl.) Schlechter var. Vargasii 
C. Schweinfurth var. nov. 
Herba speciei typicae simillima sed sepalis minoribus 
atque petalis valde latioribus obovato-spathulatis differt. 
Plant about 31 cm. tall. Basal leaves one or two, long- 
petioled ; lamina obliquely elliptic or ovate-elliptic, acute, 
broadly cuneate below, up to 9 cm. long and 8.6 cm. 
wide. Stem glabrous. Peduncle about 20 cm. high, pro- 
vided below with two remote small elliptic leaves and 
above with a small narrow bract. Raceme about 10 cm. 
long, rather densely many-flowered. Flowers whitish 
yellow, somewhat smaller than in the typical plant. 
Dorsal sepal lanceolate-elliptic, concave, obtuse or sub- 
acute, about 3.7 mm. long. Lateral sepals obliquely oval- 
ovate, subacute or obtuse, about 3.9 mm. long and 2.8 
mm. wide. Petals spatulate-obovate, broadly rounded 
at the apex, about 3.2 mm. long and 1.75 mm. wide. 
Lip similar to that of the type, deeply concave, condu-
