ORCHIDACEA:. 
PLATANTHERA LEUCOSTACHYS, Lindl. Gen. & Spec. Orch. p. 288; Hook. Fl. Bor.-Amer. 2, p. 
198. Santa Cruz, Sonora; Thurber. Near Montery, California, June. (No. 1900, Wright, a 
slender variety.) We have what we regard as the same species, from Mokelumne and Monterey, 
California, collected by Mr. Rich, and from Observatory Inlet, British America. Mr. Rich's 
specimens show a transition from the stouter form, with a dense inflorescence, to the slender 
variety, with more scattered flowers, of the plant collected by Dr. Parry. 
PLATANTHERA DILATATA, Lindl. p. 287; Torr. Fl. №. York, 2, p. 267. Mountains east of San 
Diego, California, May ; Parry. 
ErrPAcTIS GIGANTEA, Dougl. im Hook. Fl. Bor.-Amer. 2, p. 202, 1. 202. Moist ravines near 
the mouth of the Pecos; Bigelow. (No. 1901, Wright.) The leaves in Mr. Wright's specimens - 
are narrower than in the Californian plant, but in Dr. Bigelow's they are quite as broad. 
BLETIA APHYLLA, Nutt. Gen. 2, p. 194. Western Texas; Wright. Sepals deep brownish pur- 
ple. Petals dull brownish yellow ; the 3-lobed lip with 5 broad plaits or folds, purplish. 
AMARYLLIDACEAE. 
HABRANTHUS ANDERSONI, Herb. in Lindl. Bot. Heg. t. 1345: Var. Texaxus, Bot. Mag. t. 3596. 
Western Texas, from San Antonio to the Rio Grande, October. The peduncles are often 6 
inches long. (No. 1904, Wright.) 
COOPERIA PEDUNCULATA, Herb. Amaryll. p. 179, t. 42, f. 8-5, ё іп Bot. Mag. t. 3739. Prairies, 
Texas, from the Blanco river to the Rio Grande; also in Nuevo Leon, March—October. (No. 
1902, Wright.) 
CooPERIA DRUMMOKDI, Herb. in Bot. Reg. t. 1835. On hills San шан Texas, to the Rio 
Grande, August—October. (No. 1902, Wright.) 
AGAVE AMERICANA, Linn. Sp. p. 461, Kunth, Enum. 5, р. 819. Western Texas, bordering 
the Rio Grande, and in the Mexican States, west; also on the Gila. (No. 1906, Wright?) 
This is one of the species called Maguey by the Mexicans. It is an exceedingly useful plant, as 
will be seen from Mr. Schott’s notes. In many parts of Mexico, where it is now very common, 
it has doubtless been introduced. 
AGAVE AMERICANA, 8? LATIFOLIA : foliis ovatis acuminatis; floribus minoribus. Hills near 
the Copper Mines of New Mexico ; Emory ; and near Rock Creek; Bige’ow. The leaves are more 
than a foot long and 4 or 5 inches wide, forming a cone which is from 21 to 3 feet in diameter ; 
the margin armed with short spreading or reversed prickles. From the centre rises a flower 
stalk to the height of 10 feet. Only the withered and somewhat persistent flowers were col- 
lected. "These are scarcely one-third as large as those of the narrower leaved plant. The capsule 
is smooth, oblong, an inch and a half long, and three-fourths of an inch in diameter. We are 
yet in doubt as to whether this is a distinct species from A. Americara. Both are called Maguey 
in some parts of New Mexico and on the Gila, but sometimes the latter only is so named, and 
the other Mescal.
