ROBINSON AND GREENMAN. — GENUS PERYMENIUM. 521 
& Rep. ii. 612, acc. to Sch. Bip. l. ¢., hence Montanoa clematidea, Hemsl. 
l.c. 165). Stem herbaceous (?), terete, subglabrate : leaves opposite, pet- 
iolate, ovate, obtusely sinuate, 3-5-nerved from the base, very sparsely 
pubescent: panicles lax, many-headed ; involucral scales linear-lanceolate, 
acuminate, unequal: ligules 10, obovate-oblong, 1 to 1.2 cm. long, 4 to 
6 mm. broad. — Mexico, without locality, Karwinski. The writers have 
seen no specimen of this species and fail to place it satisfactorily. 
M. Oxtvx, Sch. Bip. 1. ¢. 406, is, according to the original brief 
characterization, distinguished by its small (3.5 cm. long) ovate serrate 
leaves (which on the lower surface have not only a soft pubescence but 
glands) and glabrous pales. — Guadalajara, Dr. Oliva, in 1855. 
have seen no species of this nature, and as the region about Guadalajara 
has been repeatedly and thoroughly explored in recent years by Mr. 
Pringle and Dr. Palmer without bringing to light a Montanoa of this 
type it seems likely that the plant described by Schultz belonged to 
some other genus, as the glabrous pales would suggest. 
M. Orpiegnyana, Klatt, Abh. Naturf. Gesellsch. z. Halle, xv. 328, 
p. 8 of reprint, is Hyptis erenata, Pohl! 
M. purpurea, Brongn. acc. to Groenland, Rev. Hort. ser. 4, vi- 
(1857), 544, and Montagnea purpurea, Brongn. acc. to André, Rev. 
Hort. 1863, p. 370, are merely names. 
M. Tuomasu, Klatt, Abh. Naturf. Gesellsch. z. Halle, xv. (1882), 
328, is Gymnolomia patens, Gray. The types of both species are in 
herb. Gray. 
M. triLopa, Sch. Bip. in Koch, Wochenschr. vii. 406, is wholly 
dubious, resting upon a brief and very imperfect characterization based 
Upon a specimen of unknown origin. Tt is said to resemble M. xanthii- 
folia, Sch. Bip., but to have 3_5-lobed leaves with soft pubescence. 
Monracnxa -ENsIFoLIA, Sch. Bip. in Seem. Bot. Herald, 304, is 
Gymnolomia ensifolia, Benth. & Hook. f. 
MonraGyea HETEROPHYLLA, Walp. Rep. ii. 612, is Montanoa tomen- 
tosa, Llav. & Lex. 
PERYMENIUM, Schrad. Heads (mostly small or of medium size)
