67. H. brevilabiata Rich. S^ Gal., in Ann. Sci. Nat. ser. 3, 3: 

 29 (1845). 



"H. brevilabiata Nob. Fol. lanceolatis; flor. viridibus: labello 

 oblongo-angusto, obtuso." Rich. & Gal. loc. cit. 



Plants, arising from fleshy tuberoids, about 1.6 dm. tall. Leaves 

 lanceolate, acute, 4.5-6.7 cm. long, 1.4-1.7 cm.wide.Ploral bracts 

 equalling the ovaries, lanceolate, acute, the lowermost one 

 nearly 2 cm. long. Flowers 5 or more, comparatively large. Lateral 

 sepals elliptic-oblong, rounded at the tip, 3-nerved, 1 cm. long, 

 4 mm. wide. Upper sepal elliptical, concave, about 1 cm. long. 

 Petals oblong, obtuse, about 8 mm. long, 2.75 mm. wide. Labellum 

 ligulate, obtuse, fleshy, entire, 11 mm. long, 2 mm. wide. Spur 

 about twice as long as the labellum, somewhat dilated near the 

 apex, 2 cm. long. Stigmatic processes comparatively small. 



My description is drawn in part from the type and in part from 

 the specimen collected by Pringle in the state of Michoacan.The 

 leaves of the type are broken. The longest one measures 4.5 cm. 

 in length. The spur on the lowermost flower of Galeotti's speci- 

 men is 2 cm. long. The two specimens cited below are the only 

 ones of which I have any knowledge. H. brevilabiata is appar- 

 ently a very distinct species, which on account of its simple la- 

 bellum and petals I refer to the group represented in our range 

 by H. alata and its allies.
