CRoTON CORYMBULOSUS. — Many erect stems from a ligneous base, a span to a foot high, simple below, [242] 
branching upward ; stipules subulate, deciduous ; petioles about half as long as the oval or oblong, mostly 
acutish, leaves, which are 3-1} inches long, the lowest ones broader and shorter and often acutish at base, all tripli- 
nerved at heen, penninerved upward, whitish below, greenish-gray above; stellate hairs slightly united to scales above, 
almost free and loose below ; inflorescence short, ‘loose-flowered, corym a 6-8 lines wide, mostly monecious ;

srcaitad in which Miller, DC. Prod. 15, 2, 579, followed him. But Scheele’s plant thus named and 
in Linnea, 25, 580, is an annual, mistaken by him for a shrub, which was collected by Lindheimer near ie has [243] - 
Braunfels, Tex., in 1846, and distributed in his sets under No. 526, and lately rediscovered along a railroad in 
the Indian Territory by G. D. Butler. This plant was by Miiller taken for Nuttall’s C. elipticus, from St. Louis, 
which is, however, identical with C. monanthogynus, Michx., and in Gray’s Manual, ed. 5, 438, the same species was 
again described as C. eutrigynus. 
Croton Texensis, Mill. 1. c. 692.— An annual, erect, diccious plant of the southwestern plains, Texas and 
New Mexico, 1-3 feet high, canescent or greenish-gray (when it is C. virens, Miill. 1. c. 690), with pomnaneg leaves

dra Texensis, Klotasch, and H. multiflora, Torr., are other synonymes for this plant. Nuttalls name refers to the 
curious knobs or almost spines on the capsule, which are covered with prominent tufts of stellate hairs. The styl 
are twice or often three times cleft, so that there are 12 to 24 stigmas. 
Acatypna Linpnermert, Miill. 1. c. 875. — Many weak, ascending, downy stems from a thick ligneous root, a
