GREENMAN. — NEW ANGIOSPERMS FROM MEXICO. 81 
Croton flavescens. Fruticose, 2 to 2.5 m. high: stem branched, 
covered with a brownish bark; ultimate branches subangular-com- 
pressed, finely stellate-pubescent: leaves alternate, petiolate, ovate to 
somewhat rhombic-ovate, 4 to 13 em. long, 3 to 7.5 cm. broad, subro- 
tund to acuminate at the apex and terminated by a mucro, cordate to 
obtuse at the base, stellate-pubescent on both surfaces more densely so 
beneath, yellowish-green ; petioles 1 cm. or less in length: inflorescence 
terminating the branchlets in monecious spicate racemes, 5 to 6 cm. in 
length: pistillate flowers clustered at the base of the spike; calyx-divi- 
sions triangular-ovate, acute ; style-branches deeply 2-parted, strongly 
recurved over the densely stellate-pubescent ovary: capsule nearly or 
quite 1 em. long, 8 to 9 mm. in diameter, obtusely 3-angled, somewhat - 
verrucose, closely stellate-pubescent ; carpels slightly compressed above : 
seeds elliptic-oblong, 6 mm. long, 3 mm. broad, smooth; caruncle 1.5 
mm. broad, 2-lobed. —Mexico. State of Michoacan : volcanic hills, 
Monte Leon Station, altitude 1540 m., 29 August, 1902, C. G. Pringle, 
no. 8667 (hb. Gr.). 
In general aspect OC. flavescens resembles certain forms of C. mort- 
folius, Willd., but it is readily distinguished by the longer less globose 
and more distinctly triangular capsule. he branches of the stellate 
hairs in C. flavescens are shorter than in C. morifolius, and the tomen- 
_ tum is more or less deciduous revealing the subverrucose character of 
the surface of the capsule. 
Croton Gonzalezii. Fruticose: stem and branches covered with a 
grayish bark; branchlets cinereous-stellate-pubescent : leaves short- 
petiolate, ovate, 2 to 4 cm. long, one-half as broad, mostly acuminate, 
obtuse and short-mucronate, i spicuously denticulate, rounded or su 
cordate at the base, at first minutely stellate-pubescent on both surfaces 
especially beneath, later glabrate, 3-5-nerved from the base; petioles 
to 5 mm. long, densely stellate-pubescent: inflorescence terminating 
the stem and branches in moneecious 1.5 to 3 em. long spicate racemes ; 
bracts about 1 mm. long, acute, spreading and persistent : calyx at first 
stellate-pubescent, later glabrate: petals elliptic-oblong, narrowed and 
ciliate at the base, l-nerved: stamens about 14; filaments glabrous : 
capsule 5 mm. long, closely stellate-pubescent. — Mexico. State of 
Oaxaca: Cuicatlan, altitude 600 m., 16 September, 1899, C. V. Gonzalez, 
no. 980 (hb. Gr.). 
In general habit Croton Gonzalezit resembles 0. Sonore, Torr. (C. 
Pringlei, Watson), but differs markedly in the finer stellate tomentum of 
leaves and fruit, and in the shorter petioles.
