ORCHIDACEiE 



H. nubigena about 3 flowers and several buds. In addition to this material 

 there is a drawing of a flower, petal, column and lip-base, and 

 pollinium. It appears to be distinct. The dorsal sepal is 5 mm. long, 

 3 mm. wide. The lateral sepals are 6 mm. long. The oblong, linear 

 lip is 5 mm. long. (Plate 62.)

Habenaria aggregata Howell, Fl. Nw. Amer. 628 (1902). 



" Habenaria sparsiflora. Stem rather slender, a foot or two 

 high, leafy : leaves narrowly lanceolate, acutish or acute : bracts 

 Unear-lanceolate, acuminate, usually much exceeding the green- 

 ish flowers, which are few (10 to 20) and distant: perianth thin 

 and dehcate, apparently spreading: sepals 3-nerved, the lateral 

 ones oblong or lanceolate, 2 or 3 lines long, the upper ovate and 

 a little shorter : lip several-nerved, narrow, Unear or lanceolate, 



1 That this species, heretofore not reported south of the United States, has been found 

 in Guatemala is extremely doubtful. Probably Schlechter's identification was based on the 

 closely related H. volcanica, which is common southward, or on H. limosa, which extends 

 throughout Mexico. 



2 Kranzlin {loc. cit.) cites P. Thurberi var. Grayi Wats. There never was such a combina- 

 tion. Watson says that ^'Habenaria Thurberi, var.. Gray, Proc. Am. Acad. vii. 389," is 

 H. sparsiflora.
