Mountain sides and rocky ravines, western Texas ; Chihuahua and Sonora. (Nos 639 and 1803,

1847, Lindheimer. No. 3212, Berlandier, in part; the specimens with hairy fruit being C. 
trichocarpa, Torr. Leaves 1 to 24 inches long, and half an inch to an inch wide, pubescence of 
the under surface often of a yellowish tinge. Inflorescence terminal and axillary in the upper 
leaves. Staminate flowers 10-20 or more. Petals 5-oblong. Stamens exserted ; filaments 
smooth. Disk 5-lobed, glandular. Fertile flowers usually 2, sessile, apetalous ; disk indistinct. 
Capsule globose-trigastric, covered with a short canescent stellate pubescence.

CROTON MURICATUM, Nutt. іп Trans. Amer. Phil. Soc. (п. ser.) 5, p. 113. Hendecandra Texensis, 
Klotsch in Erich. Arch. 1, p. 252. Н. multiflora, Torr. in Frém. 1st Rep. p. 96. New Mexico, 
Central and Western Texas, Chihuahua and Sonora. (No. 1799, Wright; No. 1548, Berlandier.) 
In Nuttall’s plant from Arkansas, and in specimens from the Upper Platte, the leaves are 
densely clothed with stellate hairs on both surfaces, but usually the hairs are rather scattered on 
the upper side. "The fruit is roughened (often only obscurely) with small protuberances. Styles 
2. parted and the divisions twice cleft, so that there аге 24 stigmas in all. 
CROTON MARITIMUM, Walt. Fl. Carol. p. 383; Ell: Sp. 2, p. 646. Hendecandra maritima, 
Klotsch, l. с. excel. syn. Crotonis monanthogynis. Galveston, Texas; Schott. (No. 3213 
Berlandier.) Flowers apetalous. Stamens 11-16; filaments hairy. Disk irregularly lobed: 
of the fertile flowers annular and obscurely 5-lobed. Styles thrice cleft. 
CROTON ARGYRANTHEMUM, Micha. Fl. 2, р. 215. Western Texas, on the Lower Rio Grande, 
rare. (No. 1554 and 2552, Berlandier.) Apparently suffruticose. Under surface of the leaves 
somewhat silvery with stellate scales. Flowers moncecious in short terminal racemes. The 
staminate on short pedicels. Petals 5, oblong. Stamens 9-11. Disk with 5 glandular lobes. 
Fertile flowers 4—8 in each raceme, apetalons. Styles twice cleft at the summit; more deeply 
divided in Berlandier’s No. 2552 than in the Texan plant.

Along the Rio Grande, from Frontera downward, in Western Texas, Chihuahua and Nuevo 
Leon; Wright, Thurber, Bigelow. (Nos. 1800 and 1801, Wright; No. 3211 Berlandier, a broader 
leaved form with more silvery scales.) Some me Ê the forms much resemble C. argyranthemum. 
That species differs, however, in being only slightly woody at the base ; the racemes are short 
and the flowers are 5-petalled, whereas C. procumbens is decidedly Азийн, the racemes are 
elongated and the flowers apetalous. In the latter, also, the styles are deeply twice cleft. A 
remarkably, slender variety of the plant, in which the racemes (or rather the axes, from which 
the lower flowers have fallen) are from 2 to 6 inches long, was found by Dr. Bigelow in a dry 
Es роь Presidio del Norte.
