first light blue, then changing 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. 
Pringle, on dry banks, Tomellin Cafion, Oaxaca, altitude 3,500 feet, 9 
December, 1895, no. 6265. 
Cardiospermum Galapageium. A slender climber with fur- 
rowed tomentulose stem aud biternate leaves: leaflets oblong-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. — C. Corindum, 
Rob. & Greenm. Am. Jour. Sci. ser. 3, L. 145, in part, not L.— Col- 
lected in the southern part of Albemarle Island, July, 1891, by Dr. G. 
Baur, no. 61. Distinguished by its narrow entire leaflets. O. integerri- 
mum, Radlk., the only other species with similar foliage, known to the 
writers, has a 5-sepaled calyx and cornute glands. 
Erythrzea retusa. Erect glabrous annual, 6 or 8 inches in height: 
stem leafy, 4-angled, branched; 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 i 
lines broad, the uppermost narrower and lanceolate: pedicels both term 
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 im 
length, green with narrow scarious diaphanous margins: corolla-lobes 
oblong, retuse, a line long, pale yellow in a dried state: fruit dark pron”) 
21 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 Z. divaricata, Schaffner, in its much shorter 
pedicels and erect not widely spreading branches; from £. tetramera, 
Schiede, in its retuse by no means acute corolla-lobes : from E. stricta, 
Schiede, in its 4-merous flowers. The flowers are 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 petl- 
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
