GREENMAN. — MEXICAN PLANTS. 297 



Eletia macristlimochila. Bulbs terrestrial, subglobose or some- 

 what gibbous : scape 6 to 6^ dm. high, surrounded at the base by 4 to 6 

 purplish striated acute sheaths, naked portion smooth, 1-2-vaginate, ter- 

 miuating above iu a few-flowered raceme : leaves plicate, broadly lance- 

 acuminate, smootli, 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 subcreuate, lateral margins entire, median lobe 

 deeply obcordate, apiculate in the terminal sinus, the two spreading sub- 

 creuulate or erose lobes narrowed below, and connecting with the lateral 

 lobes by a long narrow neck or isthmus ; lamella3 5, strongly undulate, 

 continuous from near the apex almost to the base of the labellum : gynoe- 

 cium narrowly winged, 2 to 2^ cm. long. — Collected by Dr. E. Palmer, 

 on a barranca, near Guadalajara, June, 1886, no. 127, also by C. G. 

 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 

 of the labellum. 



MicuosTTLis STREPTOPETALA, Rob. &, Greenm. Proc. Am. Acad, 

 xxxii. 36. A large flowered form of this species was collected by 

 C. G. Pringle, on lava beds, Serrania de Ajusco, at an elevation of 

 2,400 m., August, 1896, no. 6410. Except in the size of the flowers, which 

 are about one third larger than in the type, the specimens agree in every 

 detail with the above species. 



Aristolochia longecaudata, Watson, var. virescens. Perennial 

 from 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^ cm. broad : petioles 1 to 3^ cm. long. — 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- 

 bescent leaves, but having the same technical characters in flower and 

 fruit.
