A NEW SPECIES OF HABENARIA FROM CUBA. 



BY OAKES AMES. 



This species is closely allied to Habenaria odontopetala, 

 Rchb. f. (Fig, 2.) of peninsular Florida, Mexico, Central Amer 

 ica and Cuba. It grows in rich hillside woodlands, usually 

 where there is considerable shade, flowering during the winter 

 months. On November 9, 1902, I discovered a single specimen 

 in bloom in the Province of Pinar del Rio, near Cayajabos, a 

 town which was destroyed in the Cuban war; and on a second 

 expedition to the same locality made in January, 1903, with 

 Robert G. Leavitt, I found numerous plants, both in flower and 

 in fruit. Habenaria odontopetala was common here though its 

 season of bloom was practically at a close. However, many 

 flowers were still in good condition, and made possible a care 

 ful comparative study of both species in the field. 



Habenaria Sanbornii, sp. nov. (Fig. 1). 



Plants 2-8 dm. tall; roots fleshy, tubers short, elliptical or nearly 

 so; leaves six to eight, quite rigid, dull gray-green, never glossy above, 

 5-20 cm. long, 2-3 cm. wide, lanceolate to narrowly elliptical, lower ones 

 often obtuse, upper ones acute; cauline bracts lanceolate to lance-ovate, 

 acuminate, acute; floral bracts similar, lower ones longer than the
