large petioled plaited leaf. Flowers ratlier large, soon deflexed. — Otherwise as the 

 last genus. A single species. 



1. A. hiemale, Torr. Scape a foot high or more, with 3 or 4 greenish sheaths : 

 the radical leaf ovate-oblong to broadly oblanceolate, 4 to 8 inches long, many- 

 nerved, continuing through the winter: liuwers 6 to 20 in a loose raceme, the ovary 

 attenuate into a slender pedicel : perianth G lines long, narrow at base ; sepals and 

 petals linear-oblong, greenish-brown, 5-nerved ; lip whitish or somewhat spotted, 

 many-nerved, slightly shorter than tlie sepals, broadly obovate, attenuate into a dis- 

 tinct claw; the middle lobe undulate-margined: column nearly uniform in thick- 

 ness, very narrowly margined. — Compend. 322, & Fl. N. Y. ii. 270, t. 127. Cym- 

 hldiatn hiemale, Willd. 



Collected by Nuttall in Oregon and probably to be found in Northern Cahfornia, though not 

 otherwise known from west of the Rocky Mountains : eastward it ranges from the Saskatchewan to 

 Arkansas and the Atlantic, in rich woodlands, not common. The bulbs are renewed each year 

 and are persistent to the number of 4 or 5 upon the slender rootstock, 6 to 12 lines in diameter, 

 their substance exceedingly glutinous. The capsule is described as ovoid-oblong, rather large. 



4. HABENARIA, Willd. 



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 persistent 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. — Stems leafy or bracteate, often tall, from fleshy-fibrous or 



tuberous roots : flowers spicate or racemose, in our species not showj'- : capsules 



erect. — Gymnadenia, E. Brown, and Platanthera, Eichard. 



A large and widely dispersed genus ; twenty or more species are found in the Atlantic States, 

 several with handsome white, yellow or purple flowers and the lip often fringed. The following 

 species all belong to the section Platanthera, having the anther-cells widely divergent at base and 

 the glands distant. 



* Stem mostly slender, from an ovate or oblong tuber an inch long, bracteate, ivith 

 2 or 3 leaves at base : jioivers small, greenish, the Up scarcely exceeding the 

 uniform \-nerved sepals. 



1. H. elegans, Bolander. Stem rather stout, a foot or two high : leaves lan- 

 ceolate, acuminate, 4 to 8 inches long : spike usually dense, many-flowered ; the 

 subulate acuminate bracts a little shorter than the flowers : sepals and petals equal, 



2 lines long, the former oblong, obtuse, the latter ligidate and fleshy, obscurely 

 3-nerved ; the lip similar, with a flliform spur equalling or exceeding the ovary, 



3 to 5 lines long : pollen-masses large, half a line long : beak of the stigma promi- 

 nent, broad and rounded : capsule oblong, nearly sessile, 3 or 4 lines long. — Cat. 

 PI. St. Franc. 29. Platanthera elegans, Lindl. Orch. 285. 



Near the coast, from Monterey (Harticcg) to Vancouver Island (Li/alP), on hillsides, under oaks, 

 pines, etc. 



2. H, Unalaschensis, Watson. More slender, with an elongated and more 

 open sjjike of smaller white or greenish flowers : leaves narrowly lanceolate to 

 linear : bracts ovate, acutish, or rarely acuminate, not excelling the ovary : sepals, 

 petals and lip about a line long, the narrow or somewhat clavate spur scarcely or 

 sometimes nearly twice longer : cajisule oblong, sessile or nearly so, 3 lines long. —
