152 BOTANY. 
ORCHIDACEAE. 
SPIRANTHES DECIPIENS, Hook. Fl. Bor.-Am. 2, p. 203, t. 204. Low places, Mammoth Grove, 
Calaveras County ; May, (in fruit of the preceding season.) 
SPIRANTHES CERNUA, Jtich.; Torr. Fl. N. York, 2, p. 283, t. 129. Prairies on the Canadian 
River, and valley of the Dow Rio Grande ; Sopla Octo bulis 
CORALLORHIZA STRIATA, Lindl. Gen. € Sp. Orchid. p. 534. Corte Madera, California ; April. 
Scape 12-15 inches high, 20-30-flowered. Flowers larger than in any other North imed 
species. Lip not spotted. C. Macræi, Gray, is a yearly allied species. (Tab. XXV.) 
APLECTRUM HYEMALE, Nutt. Gen. 2, p. 197; Torr. l. c. p. 270, t. 127. Shawnee Villages, on 
the Canadian ; August. 
CYPERACEZ, 
CYPERUS INFLEXUS, Muhl.; Torr. Cyp. p. 273. Low places near Albuquerque, and on the 
Upper Canadian River. Bentham (Plant. Hartw.) refers this plant to C. aristatus of Rottboel, 
which, indeed, it much resembles, as was remarked long ago in the work just quoted ; but we 
are not yet satisfied that the two species should be united. 
Cyperus MICHAUXIANUS, Schultes; Torr. l. c. p. 259. Wet sandy places, headwaters of the 
Canadian River. This species is found as far west as the Great Colorado. 
CYPERUS DIANDRUS, Torr. Cyp. p. 264. Wet sandy places near Albuquerque, New Mexico. 
CYPERUS REPENS, Ell. Sk. 1, p. 69; Torr. Le C. phymatodes, Muhl. Grows with the last. 
CYPERUS LUTESCENS, Torr. & Hook. in Torr. Cyp. p. 433. Alluvions of Pecan Creek; August; 
and prairies near the Upper Canadian. The heads are inclined to be compound, and contain 
more numerous spikelets than Drummond's specimens, from which the original description of 
this species was taken. The spikelets, too, become brownish when old, so that the name is not 
wholly appropriate. 
FUIRENA SQUARROSA, Var. ARISTULATA, Torr. Cup. p. 291. Borders of running water, Upper 
Cross Timbers of the Canadian River. Our specimens agree exactly with those collected by 
Dr. James in Long's Expedition. 
HEMICARPHA SUBSQUARROSA, Nees. Cyp. in Endl. & Mart. Fl. Bras. p. 61, t. 4, f. 1; Torr. Fl. 
N. York, 2, p. 362. Isolepis subsquarrosa, Torr. Cyp. p. 348. Scirpus subsquarrosus, Muhl. 
Wet sandy places near Albuquerque, New Mexico. 
ELEOCHARIS ACICULARIS, R. Brown ; Torr. Cyp. in Ann. Lyc. New York, 3, p. 308. Var.? culmo 
crasso brevi, spica ovato-lanceolata valde compressa acuta 6—7-flora. Wet places near San 
Francisco; April 8; not mature. Differs from the ordinary form of the plant in its stout culm, 
(which is 2-3 inches high,) and much compressed dark chestnut-colored scales. There are 3 
stamens and a 3-cleft style, which has a distinct tubercle at its base ; but no bristles were found. 
ELEOCHARIS PYGMEA, Torr. l. c. (excl. syn. Vahl.) Cocomungo, California; April IS. Al- 
though the specimens are rather too young for certain determination, they agree very well with 
the plant of the Eastern States. Kunth (Enum. 2, p. 158) retains Scirpus pusillus of Vahl in 
the genus Scirpus, although he seems to have examined the original specimens of that plant. 
He also refers to it the S. pusillus of Willdenow's herbarium ; but quotes it again under his 
own Eleocharis reclinata! Vahl’s plant was from New England, and seems to be only one of 
the forms of E. acicularis. Willdenow's is probably not different, as he received most of his 
North American plants from Muhlenberg, who refers S. pusillus, Vahl, to S. trichodes, which is 
undoubtedly Eleocharis acicularis. 
ELEOCHARIS PYGMHA, Var. ANACHJETA. Moist places near Albuquerque, New Mexico. This 
variety was noticed in the botany of Nicollet's Report, p. 163. We have it also from the Red 
River, Louisiana, where it was collected by Dr. Hale.
