first light blue, then chaugiug to white, half line in diameter, spreading : 

 stigmas deeply 2-parted ; divisions clavellate : capsule smooth, about a 

 line in diameter: seeds oblong, light blue, three fourths line in length, 

 deeply pitted and with a conspicuous caruncle. — Collected by C. G. 

 Pringle, on dry banks, Tomellin Canon, Oaxaca, altitude 3,500 feet, 9 

 December, 1895, no. 6265. 



Cardiospermum Galapageium. A slender climber with fur- 

 rowed tomentulose stem aud biternate leaves : leaflets oblone lanceo- 

 late, attenuate, entire, abrupt at base, finely tomentose upon both surfaces, 

 slightly paler beneath, prominently 1-nerved and pinnately veined, the 

 lateral leaflets of each division much smaller than the terminal: peduncles 

 slender, spreading, tendriliferous beneath the umbelliform inflorescence : 

 sepals 4, the outer pair a line, the inner 2 lines long : glands upon the 

 upper side of the disk short, rounded, not at all cornute. — G. Corindum, 

 Rob. & Greenm. Am. Jour. Sci. ser. 3, L. 145, in part, not L. — Col- 

 lected in the southern i^art of Albemarle Island, July, 1891, by Dr. G. 

 Baur, no. 61. Distinguished by its narrow entire leaflets. C. integerri- 

 mum, Radlk., the only other species with similar foliage, known to the 

 writers, has a 5-sepaled calyx and cornute glands. 



Erythrsea retnsa. Erect glabrous annual, 6 or 8 inches in height: 

 stem leafy, 4-angled, bi'anched ; branches erect or nearly so, mostly rather 

 short and again branched: leaves oblong-elliptical, obtuse or mucronu- 

 late at the end, somewhat narrowed at the base, half inch long, 2 to 3 

 lines broad, the uppermost narrower and lanceolate : pedicels both termi= 

 nal and lateral on the branches, short, 1 to 2 lines in length : flowers 

 4-merous, calyx-lobes lance-linear, attenuate, slightly carinate, 2 lines in 

 length, green with narrow scarious diaphanous margins : corolla-lobes 

 oblong, retuse, a line long, pale j^ellow in a dried state : fruit dark brown, 

 2\ lines long. — Collected by C. G. Pringle, in springy meadows, Sierra 

 de San Felipe, Oaxaca, altitude 7,500 feet, 11 December, 1895, no. 6300. 

 This species differs from E. divaricata^ Schaffiier, in its much shorter 

 pedicels and erect not widely spreading branches ; from E. tctramera, 

 Schiede, in its retuse by no means acute corolla-lobes : from E. stricta, 

 Schiede, in its 4-raerous flowers. The flowers ai-e small and appear to 

 remain closed and to be cleistogamous. 



Nama Pringlei. Low slender branching annual of similar habit to 

 the following and with similar pubescence : leaves oblong, entire, rounded 

 at the apex, rather gradually narrowed at the base to a short slender peti- 

 ole : calyx as in the last : corolla showy, 5 lines long and equally broad, 

 with short yellow tube and deep blue spreading rather deeply 5-lobed
