below : capsule oblong-ovate, 6 to 9 lines long, shortly attenuate to 

 a short pedicel, — G. striata, Torrey, Pac. R. Rep. iv. 152, t. 25. In 

 the Sierra Nevada and mountains of N. California. Recognized by 

 Dr. Torrey as distinct from C. MacrcBi, which is doubtless identical 

 with the original C. striata of Lindley. The figure cited fails to 

 represent the gibbosity of the perianth. C. striata is very similar, 

 but with the flowers still larger (often 6 or 7 lines long) ; lip rather 

 less fleshy, somewhat narrower below, reflexed above the base, and 

 bearing the prominent laminie upon the arch : ranging from Washing- 

 ton Territory and Oregon to the Great Lakes. 



Habenaria sparsiflora. Stem rather slender, a foot or two 

 high, leafy : leaves narrowly lanceolate, acutish or acute : bracts linear- 

 lanceolate, acuminate, usually much exceeding the greenish flowers, 

 which are few (10 to 20) and distant : perianth thin and delicate, 

 apparently spreading: sepals 3-nerved, the lateral ones oblong or 

 lanceolate, 2 or 3 lines long, the upper ovate and a little shorter : lip 

 several-nerved, narrow, linear or lanceolate, 3 or 4 lines long, nearly 

 equalling the narrow sjjur : anther emarginate ; stalks of the pollen^ 

 masses very slender : glands orbicular : beak of stigma broadly tri- 

 angular : capsule oblong, sessile, 6 lines long. — H. Thurheri, var.. 

 Gray, Proc. Am. Acad. vii. 389. Common in the Sierra Nevada and 

 mountains of Northern California ; marked by its peculiar habit. 

 The typical H. Thurheri is to be referred to H. leucostachys. 



Habenaria pedicellata. Stem leafy : raceme loose, 20-30-flow- 

 ered, with linear-lanceolate bracts shorter than the long-pedicellate 

 flowers : sepals 3-nerved, 2h lines long, oblong, the upper ovate ; lip 

 fleshy, several-nerved, oblong-lanceolate, half broader at base, 3 lines 

 long ; spur filiform, twice longer than the sepals : pollen-masses at- 

 tached to the oblong glands by a short thick pedicel: beak of stigma 

 ovate-triangular, prominent : capsule ovate-oblong, 4 lines long, attenu- 

 ate into a slender pedicel about as long. — A single specimen of this 

 very distinct species was collected by Prof. W. H. Brewer (n. 1453, 

 in part) in the Shasta Mountains, California ; September. 



Habenaria Cooperi. Stout and tall (3 feet high), leafy : flowers 

 numerous, spicate, yellowish green : sepals and petals nerveless, con- 

 nivent at base, rather thick, equal, 2 lines long ; lateral sepals oblong, 

 the upper ovate ; lip ovate, truncate at base, with a broad claw ; spur 

 short and thick : glands orbicular : beak of stigma triangular : capsule 

 oblong, sessile, 4 or 5 lines long. — On clay hills near San Diego, Cali- 

 fornia ; Dr. J. G. Cooper. A strongly marked species, allied to H. 

 hyperhorea, R. Brown. Of the other western species of this genus,
