GREENMAN. — MEXICAN PLANTS, 297 
Bletia macristhmochila. Bulbs terrestrial, subglobose or some- 
what gibbous: scape 6 to 64 dm. high, surrounded at the base by 4 to 6 
_ purplish striated acute sheaths, naked portion smooth, 1—2-vaginate, ter- 
-Mminating above in a few-flowered raceme: leaves plicate, broadly lance- 
acuminate, smooth, about 7-nerved, 12 to 30 cm. long, 2 to 4 cm. wide: 
bracts triangular-acuminate, 10 to 14 mm. long: flowers 5 to 8 cm. in 
diameter, rose-purple in the dried state: sepals oblong, short-acuminate, 
a little narrowed at the base, 3 to 4 cm. long, 10 to 12 mm. broad: petals 
oblong, obtuse or rounded at the apex, rather abruptly narrowed below, 
considerably broader than the sepals; labellum deeply 3-lobed, lateral 
lobes broad and obtusely triangular, strongly flabellate-nerved, the upper 
nearly horizontal margins subcrenate, lateral margins entire, median lobe 
deeply obcordate, apiculate in the terminal sinus, the two spreading sub- 
jcrenulate or erose lobes narrowed below, and connecting with the lateral 
lobes by a long narrow neck or isthmus; lamella 5, strongly undulate, 
| Continuous from near the apex almost to the base of the labellum: gyne- 
cium narrowly winged, 2 to 24 cm. long. — Collected by Dr. E. Palmer, 
on a barranca, near Guadalajara, June, 1886, no. 127, also by C. G. 
3 Pringle, in the same locality, 2 July, 1889, no. 2875. This plant has , 
: been confused with B. campanulata, Llav. & Lex., to which species it — 
was referred by Dr. Sereno Watson. It may however be distinguished 
from B. campanulata, as well as from B. fulgens, Reichb., a large flowered 
species growing in similar localities, by the long narrow neck or isthmus 
f the labellum, 
Microstyiis srrepropeTaLa, Rob. & Greenm. Proc. Am. Acad. 
xxxii. 386. A large flowered form of this species was collected by 
i ¢. G. Pringle, on lava beds, Serrania de Ajusco, at an elevation of 
tl 2,400 m., August, 1896, no. 6410. Except in the size of the flowers, which 
__ re about one third larger than in the type, the specimens agree in every 
) detail with the above species. ; : 
| Aristolochia longecaudata, Watson, var. virescens. Perennial 
ftom a ligneous base: stems decumbent or prostrate, sulcate, some- 
What retrorsely hirsute-pubescent: leaves ovate to ovate-oblong, often 
acuminate, pubescent on either surface, 3-5-nerved, 3 to 9 cm. long, 1} 
to 5+ em. broad : petioles 1 to 34 cm. léng. — Collected by C. G. Pringle, 
| about Cuernavaca, altitude 1,500 m., 23 July, 1896, no. 6383. A form 
differing from the type of the species by its larger thinner and less pu- 
j bescent leaves, but having the same technical characters in flower and
