32 ERYTHEA. 



pubescent, dilated at base; internodes much exceeding the leaves: 

 flowers single or in twos, the lowermost sessile in the axils of the 

 upper leaves, the upper contracted into a leafy bracted spike; bracts 

 lanceolate, nearly sessile, exceeding the flowers: calyx campanulate;. 

 shorter than the tube of the corolla, the teeth deltoid-acuminate, 

 tipped with a white arista, the anterior longest, all hirsute ciliate; 

 corolla 12 mm. long, purplish, puberulent without, especially the 

 upper lip, glabrous or slightly bearded within; lower lip white 

 spotted. 



Collected by F. H. Lamb, 1138, along river banks, Hoquiam, 

 Chehalis County, Washington, June 2, 1897, and dedicated at his 

 request to Mr. G. H. Emerson. This species resembles somewhat 

 S. ciliatus Dough, but is at once distinguished by its very different 

 flowers. 



Listera caurina. Stems slender, 15-30 cm. high, glabrous be- 

 low the leaves, the inflorescence glandular pubescent; leaves sessile 

 by a clasping base, ovate, obtuse or acutish, glabrous, 3-5 cm. long; 

 flowers 5-40, usually about 15, greenish; bracts ovate, acute, ^ the 

 length of the pedicel, this 5-7 mm. long; sepals and petals lanceolate, 

 spreading not reflexed in anthesis; lip 4 mm. long, cuneate, obovate, 

 with an inconspicuous tooth between the two shallow notches at 

 apex, and a small tooth on each side near the base; column stout; 

 1^ mm. long, incurved ; capsule erect, ovoid, 5-6 cm. long. 



Common in the Cascade Mountains, at about 3,000 ft. alt., in 

 coniferous woods, Henderson, Piper; Olympic Mountains, Lamb; 

 Cedar Mountains, Latah County, Idaho, Piper. This species has 

 been confused with L. convallarioides Nutt., which may easily be dis- 

 tinguished by the much larger (10-12 mm. long) deeply notched lip, 

 shorter pedicels, and by having the sepals strongly reflexed in 

 anthesis. L. convallarioides is a much rarer plant in this region 

 than L. caurina, but we have examples from all our mountain 

 ranges which match exactly with eastern specimens.
