portion. Bracts of the fertile flowers coarscly and acutely 5-toothed, sparingly ciliate with 
rigid hairs. Capsule hispid at the summit. According to Dr. Gregg this plant is used by the 
Mexicans as а wash for sore gums and loose teeth, and as an application to ulcers. It is doubt- 
ful whether this is A. phleoides, as that species is said to be an annual. Our plant seems to be 
nearly allied to A. prunifolia, but that also is described as an annual. 
ACALYPHA HEDERACEA (n. sp.): e caudice lignoso multicaulis, molliter incano-pubescens seu 
villosa ; foliis orbiculari-reniformibus longe petiolatis crenato-dentatis ; spicis dioicis (rarissime 
monoicis) terminalibus pedunculatis, stamineis gracilibus fcemineis brevibus crassis, bracteis 
obtuse 9—10-dentatis. Damp places, valley ofthe Pecos ; Bigelow. Neuvo Leone and Chihuahua, 
Gregg, Edwards. May—September. (No. 648, 1813 and 1814, Wright. ( “Хо 413, Lindheimer.) 
Plant slender, prostrate, branches 6—15 inches long. pare | 6-10 lines in diameter, mostly 
broader than long, truncate or cordate at the base. Staminate spikes 6-10 inches long; the 
peduncle often 1-2 inches long. Fertile spikes half an inch long. Bracts cucullate. Fruit 
hispid.—In one of Mr. Wright’s specimens (No. 1813) there are sessile axillary few-flowered 
fertile spikes, and others that are androgynous, consisting of a short pedunculate staminate 
spike with a single fertile flower at the base. | ; 
ACALYPHA RADIANS (n. sp.): e basi suffruticosa multicaulis, pilis longis pateutissimis villosa ; 
foliis longe petiolatis orbiculari-reniformibus inciso 7—13-fidis, lobis sublinearibus ; spicis dioicis 
2 terminalibus pedunculatis, stamineis oblongo-linearibus, fæmineis crassis ; bracteis obtuse 9-10- 
dentatis. Western Texas, especially along the lower Rio Grande, and in the adjoining Mexican 
States. (No. 251, Coll. П,) Texas, Drummond. No. 649, Wright. No. 636, 1070, 2046, and 2500, 
Berlandier ) This is certainly very near the last, but I have not seen intermediate forms. It 
it is easily distinguished by its hairiness, and the radiately lobed leaves.

Rocky ravines and hill sides, New Mexico, and western Texas, along the Rio Grande to the 
Gulf. (No. 307, Coll. II. Texas, Lindh. No. 260, Coll. III. Texas, Drummond. No. 1793, 
Wright.) No. 647 of Wright’s earlier collection in the same plant with the flowers and fruit in 
ап abnormal state. І can find no sufficient characters for distinguishing this plant from T. 
urtiezfolia, Mx. The stems are at first upright, but at length prostrate or sometimes even а 
little twining. The length of the spikes is very variable. In specimens from Arkansas the 
fertile flowers have the calyx 6-petalled, and the staminate 4-5-sepalled, 4—5-androus. The 
stems are somewhat woody at the base. 
TRAGIA URTICHFOLIA, Var.? LACINIATA : foliis pedatim 3-partitis, laciniis pinnatifidis, intermedio 
>» longiore. Sonora, Mexico, Thurber. No. 1795, Wright. Stem apparently prostrate, 12-15 
inches long, paniculately branched, hirsute. Leaves 1-11 inch long, the lower ones on short 
petioles, upper nearly sessile, pedately divided to the base, pinnatifidly cut into acute segments or 
teeth ; the lateral lobes sometimes unequally 2-cleft. Racemes terminating the short branches, 
few-flowered, the lowest flower fertile. Calyx and fruit as in the ordinary form, Fruit. A 
remarkable variety, approaching (by the description) T. cannabina. Mr. Schott collected in the 
AS ~ northwestern part of Sonora specimens of à Tragia that seems intermediate between T. urtice- 
| 5 folia and this plant. The leaves are oblong-ovate and coarsely toothed, and part of them are 
‹ 2-lobed at the base or somewhat halberd-form, showing the tendency to become pedate.
