LISTEBA ORCHIDACE^E 631 



EPIPACTIS 



linear-lanceolate, 2-3 lines long : lip broadly cuneate, with 2 obtuse lobes at 

 the dilated apex, 4-5 lines long, generally with a tooth on each side at base: 

 column elongated but shorter than the lip, a little incurved, with 2 short 

 projecting wings above the anther : capsule obovoid, about 3 lines long. 

 In wet places in forests, southern Oregon to California and the Atlantic 

 States. 



L. canrina Piper Eryth. vi, 32. L. convallarioides Hook, not Torr. 

 Stem slender, 5-12 inches high, glabrous below, densely glandular-pu- 

 bescent above the leaves: leaves obovate to oval, or elliptic- ovate, 1-4 

 inches long, thin, obtuse and slightly apiculate to acute, rounded or trun- 

 cate at base : raceme loosely many-flowered : bracts 1-3 lines long, rhombic- 

 ovate, acuminate, the lower sometimes 2-flowered and bifurcate : flowers 

 dull yellowish, en slender pedicels 4 6 lines long: sepals and petals lanceo- 

 late to linear-lanceolate, about 2 lines long, spreading : lip about 3 lines 

 long, narrowly oblong, dilated and rounded at the retuse apex, a slender or 

 almost filiform tooth on each side at the base, with a papilla at the base 

 of each tooth: column short, not stout: capsule ovoid, 3 lines long. In 

 damp woods in the high mountains, Oregon to Alaska and Idaho. 



7 EPIPACTIS K Br. Ait. Hort. Kew. ed. 2, v, 201. 



Tall herbs with fibrous roots, simple leafy stems and rather 

 large flowers in terminal leafy-bracted racemes. Sepals and pet- 

 als nearly equal : lip free, deeply concave at the base, without 

 callosities, narrowly constricted and somewhat jointed in the 

 middle, the upper portion petaloid. Column short, erect. An- 

 ther sessile behind the broad truncate stigma, on a slender jointed 

 base, 2-celled, obtuse. Pollen-masses coarsely granular, becoming 

 attached above to the gland capping the small rounded beak of 

 the stigma. 



E. gigantea Dougl. Hook. Fl. ii, 220, t. 202. Stem stout, leafy, 1-5 

 feet high, nearly smooth : leaves from ovate below to narrowly lanceolate 

 above, 3-8 inches long, acute or acuminate, somewhat scabrous on the 

 veins beneath : racemes pubescent: bracts large and foliaceous, lanceolate 

 or linear-lanceolate, as long or longer than the flowers : pedicels slender, 

 2-4 lines long : sepals ovate-lanceolate, 6-8 lines long, the upper concave : 

 petals slightly smaller: lip as long as the petals, the saccate base with 

 erect wing-like margins, strongly nerved and the nerves callous tuberculate 

 near the base, the dilated summit ovate- lanceolate, entire, somewhat 

 wavy-crested : anther nearly 2 lines long : capsule oblong, 8 lines long, 

 reflexed. In springy places along streams, California to Brit. Columbia. 



8 CEPHALANTHERA Richard. Annot. 21. 



Mostly leafy-stemmed herbs from creeping rootstocks, with flat 

 leaves, or leafless, and middlesized flowers in bracted spikes. Se- 

 pals and petals nearly equal, connivent, the latter somewhat 

 united and galeate. Lip free, concave, contracted and some- 

 what jointed in the middle. Column slender, elongated. Anther 

 shortly stipitate, so as to be nearly or quite above the level of the 

 top of the stigma. Pollen-masses not connected nor attached to 

 a gland. Stigma wholly beakless. 



C. Oregana Reichenb. f. Linnese xii, 53. Whole plant white and 

 without leaves, parasitic, 10-18 inches high, with 3-5 somewhat dilated 

 sheaths below and usually a few free linear-lanceolate bracts above : raceme
