Gray, PI. Wright, i. 20,) caunot be SlJaUgnosa, Cav., with " capsulis 

 durissimis." In Mexico it comes so near the boundary (coll. Berlandier, 

 Palmer, &c.) that it is Hkely to reach Texas. It is known by its seem- 

 ingly cordate sepals equalling the numerous subulately erect-awned 

 and villous-hirsute carpels, which are as large as those of the preceding 

 species. 



A. Palmeri, Gray, and A. aurantiacum, "Watson, are apparently 

 good species of N. W. Mexico and Lower California, which come very 

 near to our borders. 



A. PERMOLLE, Don, is the Florida plant (otherwise only West In- 

 dian) which in Chapman's Flora is taken for A. Jacquini. 



A. Wrightii, Gray, of Texas, Arizona, and adjacent Mexico, is the 

 species most resembling A. Jacquini, Don. 



A. Parishii, Watson, Proc. Am. Acad. xx. 357, is a recently added 

 species of the same group, but wholly herbaceous, with short peduncles 

 and short calyx. 



A. LemmoNi, Watson, 1. c, is a species near to the Mexican A. Ber- 

 landieri, Gray, which Mr. Watson has partly characterized ; and to 

 the latter may be referred the "306, Abutilon" of Pringle's Chihuahua 

 distribution, a var. dentatum. 



A. Xanti is a name which may be applied to the plant of Lower 

 California, noted as " A. Californicum, Benth. var." in Proc. Am. 

 Acad. V. 154, which cannot be Bentham's species. It goes with those 

 two very closely related species, A. Sonorce, Gray, and A. reventum, 

 Watson, Proc. Am. Acad. xxi. 418, which are heibaceous, large-leaved, 

 and with a veiy naked and ample compound panicle of small flowers. 

 This one has neither the long beard-like hairs of A. Sonorce, nor the 

 smooth stems of A. reventum, and has a different and larger calyx, 

 nearly equalling the cuspidate beaked fruit. 



A. MALACUM, Watson, Proc. Am. Acad. xxi. 446, is quite well dis- 

 tinguished from the next by the more glomerate or paniculate flowers, 

 and the longer as well as permanently erect calyx, and generally by 

 the foliage. 



A. INCANDM, Don. A. Texense & A. Nattallii, Torr. & Gray, Fl. 

 In the Botany of the Wilkes South Pacific Expedition, I noted that 

 A. incanmn of the Sandwich Islands was hardly distinguishable from 

 A. Texense. I now find that the characters there mentioned are of 

 no avail. The seeds of our plant, although quite glabrous when young, 

 become minutely downy in age. We must combine the species, not- 

 withstanding the disjointed range. 



A. PARVULUM, Gray, to which belong some specimens which have
