bo wise to suggest more than a close relationsliip of the two described 

 species.

 ing hairs intermixed witli densely crowded stipitate glands, heavy scented: 

 tubers white : stems somewhat striate-angled : leaves pinnatisect, 5 to 

 12 cm. long, 4 to 8 cm. broad, usually auricled at the base by small 

 subfalcate leaves of reduced axillary branches ; segments 7 to 9, lance- 

 oblong to ovate, 1.5 to 4 cm. long, 0.5 to 2 cm. broad, somewhat acumi- 

 nate, obtuse, abruptly contracted below into an oblique subpetiolulate 

 base ; intermediate segments much smaller, very unequal, rarely more 

 than a centimeter in lenijth : inflorescence terminalin<j the stem and 

 branches in pedunculate false dichotomous more or less horizontally 

 spreading cymes : flowers several : peduncles 1 to 2.5 cm. long, jointed : 

 calyx 5-parted ; segments sublanceolate to somewhat oblong, often 

 abruptly contracted into an attenuated apex, persistent : corolla 5- 

 angled, plicate, about 1 cm. high and 2 cm. broad, white : ovary and 

 st3de glabrous: fruit conical-ovate, 10 to 13 mm. long, two-thirds to 

 nearly as broad, glabrous. — Mexico. State of Hidalgo : limestone 

 hills. El Salto Station, 15 September, 1902, C. G. Pringle, no. 8692 

 (hb. Gr.). 



Seymeria integrifolia. A much-branched annual, glabrous or 

 slightly puberulent under a lens, somewhat viscid : leaves mostly op- 

 posite, linear to subulate-linear, 0.5 to 1.5 cm. long, about 1 mm. broad, 

 entire, glabrous : flowers small, 7 to 8 mm. long, during anthesis nod- 

 ding on slender naked recurved i^edicels : calyx about one-half as long 

 as the fully developed corolla, deeply 5-parted into 5 lance-linear acut-

 on rocky hills near Guadalajara, 13 May, 1901, C. G. Pringle, no. 9660

Stexandrium barbatum, Torr. & Gray, Pacif. R. Rep. ii. 1G8, t. 4; 

 Torr. Bot. Mex. Bound. 122. Specimens of this species were collected 

 by Mr. C. G. Pringle on dry hills near Ciudad Juarez, State of Chihua- 

 hua, Mexico, at an altitude of 1140 m., 5 May, 1901, no. 8501 (hb. Gr.). 

 Although this species is well known from Texas and New Mexico, 

 through the collections of Wright, Thurber, Pope, Lemmon, and Vasey, 

 yet it does not seem to have been hitherto reported from Mexico. 



Anisacanthus Gonzalezii. Suffruticose : stem much-branched, 

 below covered with a grayish bark, above striate and finely appressed- 

 sericeous-pubescent to nearly glabrous : leaves opposite, short-petiolate,
