 Central and Western Texas, Chihuahua and Sonora. (No. 1799, Wright; No. 1548, Berlandier.) 

 In NuttalTs plant from Arkansas, and in specimens from the Upper Platte, the leaves are 

 densely clothed with stellat^e 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 are 24 stigmas in all.

of the fertile flowers annular and obscurely 5-lobed. Styles thrice cleft. 



Croton argyranthemum, Michx. Fl. 2,^, 215. Western Texas, on the Lower Eio Grande, 

 rare. (No, 1554 and 2552, Berlandier,) Apparently suffruticose. Under surface of the leaves 



somewhat silvery with stellate scales. Flowers mona3cious 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, apetalous. 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, Thurher^ Bigeloio. (Nos. 1800 and 1801, Wright; No. 3211 Berlandiery a broader 



leaved form with more silvery scales.) Some of 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 shrubby, the racemes are 



elongated and the flowers apetalous- In the latter, alsOj 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 



arroyo opposite Presidio del Norte.
