Linnsea, 25, 580, is an annual, mistaken by him for a shrub, which was 

 collected by Lindheimer near New 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 Muller taken for 

 Nuttall's C. ellipticus, from Saint Louis, which is, however, identical with C. 

 monanthogynus, Michx., and in Gray's Manual, ed. 5, 438, the same species 

 was again described as O. eutrigynus. 



Ckoton Texensis, Mull. I. c. 692. — An annual, erect, dioecious plant of 

 the southwestern plains, Texas and New Mexico, 1-3° high, canescent or 

 greenishrgray (when it is C. virens, Mull. I. c. 690), with linear-oblong leaves 

 2 J' long on petioles \- J' long, without any glands; stellate hair free, not 

 scaly; flowers apetalous; stamens usually 10-13 ; filaments hairy; styles 

 twice or thrice 2-cleft at base, and, like the capsules, stellate-canescent; seeds 

 orbicular-ovate, somewhat compressed, with a small deciduous caruncula 

 below the apex. — Santa F4, N. Mex., Rothrock, 1874 (37), originally 

 described by Nuttall as C. muricatus, a name already preoccupied. Hen- 

 decan&ra Texensis, Klotzsch, and H. multiflora, Torr., are other synonyms 

 for this plant. Nuttall's name refers to the curious knobs or almost spines 

 on the capsule, which are covered with prominent tufts of stellate hairs. 

 The styles are twice or often three times cleft, so that there are 12 to 24 

 stigmas. 



Acaltpha Lindheimeri, Mull. 1. c. 875. — Many weak, ascending, downy 

 stems from a thick ligneous root, a span to a foot high, branching from the 

 base: leaves lanceolate-ovate, acute at both ends, serrate upward, hairy, 

 on short petioles, lower ones broader and shorter ; slender, dense-flowered, 

 terminal spikes 2-3' long, staminate upward; shorter spikes from the upper- 

 most leaf-axils ; bracts oval, deeply dentate ; styles divided into many very 

 slender, long-protruding, red branches. — Ash Creek, Arizona, Rothrock, 

 1874 (299), and through New Mexico to Western Texas. — Very near the 

 Mexican A. phleoides, Cav., with which Torrey, Bot. Mex. Bound. 199, was 

 inclined to unite it. The slender spikes with the delicate bright red fringes 

 give the plant a very elegant appearance. 



Jatropha macrorhiza, Benth. PI. Hartw. 8; Miill. I. c. 1087, var. 

 septempida. — Stems a span to a foot high, glabrous, very leafy ; leaves
