6, CROTON L. 
Herbs or shrubs, with stellate pubescence or scales, alternate stipu- 
late leaves, moncecious (rarely dicecious) flowers mostly in terminal 
spikes or spicate racemes: staminate lowers with a 5 (rarely 4 to 6)- 
parted calyx, as many (mostly small) hypogynous petals (usually 
present), as many glands of the disk alternate with the petals, 5 or 
more stamens with anthers inflexed in the bud: pistillate flowers with 
a 5 to 10-cleft or parted calyx, petals none or minute rudiments, 3 
rarely 2 to 4 )-celled ovary separating in fruit into as many 2-valved 
1-seeded carpels, and carunculate seeds. 
* Petals of staminate flowers evolute, of the pistillate rudimentary or obsolete. 
+ Calyxes equally 5-parted, the staminate pilose: petals (staminate) 5: stamens 6 to 20. 
++ More or less scaly. 
1. C. punctatus Jacq. Herbaceous perennial, covered throughout with stellate 
silvery scales: stems erect (1.5 to 3dm. high), umbellately branched: leaves obovate 
or oblong (2.5 to 3 cm. long), obtuse, entire, silvery beneath, narrowed into a petiole: 
racemes sessile, oblong, obtuse: fertile flowers numerous and crowded: calyx-lobes 
acute: stamens 10 to 12, hairy: styles leng and slender, 4-cleft: pod much longer 
than the calyx. (C. argyranthemum Michx,)—From the lower Rio Grande to Hockley, 
2. ©. corymbulosus Engelm. Whitish, stellate-sealy, with many erect stems 
from a woody base (1.5 to 3 dm, high): leaves oval or oblong, acutish, 3 to 4 em.
