& Rep. ii. G12, ace. to Sch. Bip. 1. c, hence Montanoa clematidea, Ilemsl. 

 1. 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, obovatc-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. Oliv^, Sch. Bip. 1. c. 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. We 

 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. Orbignyana, Klatt, Abh. Naturf. Gesellsch. z. Halle, xv. 328, 

 p. 8 of rejirint, is Hyptis crenata, Pohl! 



M. PURPUREA, Brongn. ace. to Greenland, Rev. Ilort. ser. 4, vi. 

 (1857), 544, and Montagn<Ba purpurea, Brongn. ace. to Andre, Rev. 

 Hort. 1863, p. 370, are merely names. 



M. Thomasii, Klatt, Abh. Naturf. Gesellsch. z. Halle, xv. (1882), 

 328, is Gymnolomia 'patens, Gray. The types of both species are in 

 herb. Gray. 



M. TRILOBA, 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. It is said to resemble 31. xanthii- 

 folia, Sch. Bip., but to have 3-5-lobed leaves with soft pubescence. 



MoNTAGNiEA EXSiFOLiA, Sch. Bip. in Seem. Bot. Herald, 304, is 

 Gymnolomia ensifoUa, Benth. & Hook. f. 



MoNTAGN^A HETEROPHYLLA, "Walp. Rep. ii. 612, is Montauoa tomen- 

 tosa, Llav. & Lex. 



PERYMENIUM, Schrad. Heads (mostly small or of medium size) 

 heterogamous ; ray-flowers ligulate, styliferous, fertile ; disk-flowers per- 

 fect, regular. Involucre hemispherical, campanulate or subcylindric, the 

 bracts 1-4-seriate, ap2:)ressed or squarrose, often ciliated. Pales carinate, 

 folded about the achenes ; receptacle convex. Disk-flowers with a rela-
