HABENABIA 



oblong obtuse entire or with a tooth on one or both sides near the base, 

 narrowed to a short claw, thin and concave, the ridges only slightly prom- 

 inent: column nearly equalling the petals, slender, the narrow margins 

 scarcely broader or thicker below : stigma projecting and cucullate : capsule 

 5-8 lines long, attenuate into the short slender pedicels, reflexed. Common 

 jn the high mountains, Alaska to California. 



*- - Spur very short or not at all prominent : sepals and petals

C. innata R. Br. Ait. Hort. Kew. ed, 2, v, 209. Stems slender, 

 glabrous, 4-12 inches high, clothed with 2-5 closely sheathing scales : ra- 

 cemes 1-3 inches long, 3-12-flowered : flowers dull purple, about 6 lines 

 long, on very short minutely bracted pedicels : sepals and petals narrow, 

 about 3 lines long: lip shorter than the petals, oblong, whitish, 2-toothed 

 or 2-lobed above the base : spur a sac or small protuberance adnate to the

 nent : also in Europe. 



* * Flowers larger, striate-veined, not spotted: spur none, the

 clothed with several scarious bracts : racemes 2-6 inches long, 10-25-flowered: 

 flowers brownish-purple : sepals and petals narrowly elliptic, striate with

Tribe 2 Ophrydeae Lindl. Orch. 257. Flowers mostly spicate or 

 racemose. Anther one, connate with the column and persistent upon 

 its face immediately above the stigma. Pollen-masses 2, of coarse 

 grains united by an elastic web, each mass attached by a stalk to a 

 viscid gland. 



3 HABENARIA Willd. Sp. PI. iv, 44. (1804) 



Leafy-stemmed plants with bulbous or fleshy-fibrous roots, en- 

 tire mostly green leaves and rather small flowers in terminal 

 bracted racemes or spikes. Perianth ringent : sepals and petals 

 nearly alike, convergent, or the lower sepals spreading: lip flat 

 and spreading, 3-lobed or entire, with a slender spur at base, 

 without ridges or callosities : column very short. Anther persis- 

 tent upon the face of the column immediately above the stigma, 

 the cells parallel, or divergent at base. Pollen-masses one in 

 each cell, of coarse grains united by an elastic web, each attached 

 at base by a pedicel to an exposed viscid gland on the upper edge 

 or at the side of the stigma. 



* Stem mostly slender, from an ovate or oblons tuber, with 2-3 

 leaves at base and bracteate above : flowers numerous, small, greenish 

 white, the Jip scarcely exceeding the uniform 1-nerved sepals. 



H. elegans Bolander Cat. PI. St. Franc. 29. Stem rather stout, 1-3
