88\ C. SPATHULATA (sp. uov.) : humilis ; ramis divaricatis ; foliis spathulatis ob- 

 tusis retusisve muticis nunc obtuse mucronatis inferne longe attenuatis subpetiolatis, 

 venis latissimis nerviformibus subtus prominulis ; pedicellis quam folia dimidio bre- 

 vioribus. — On the Rio Grande, Texas ; and prairies on the San Felipe, July ; in 

 flower. — Shrub from one to six feet, very much branched ; the rigid branches divaii- 

 cate, often spinescent : some specimens bear small axillary spines, shorter than the 

 leaves ; others are unarmed. Leaves alternate, or on the flowering branches all fas- 

 cicled, 3 to 6 lines long, including the attenuated base, broadest near the apex, 

 thickish, entire, pinnately 5 - 7-veined ; the veins very broad and prominent under- 

 neath, as in C. microphylla, but not so numerous nor contiguous, nor are the leaves 

 so coriaceous. Pedicels solitary or fascicled from the centre of the tufts of leaves. 

 Flowers much as in C. obovata, but smaller, apetalous, pentandrous. Ovary appar- 

 ently one-celled and two-ovuled. Fruit not seen. — A congener of C. microphylla, 

 Cav., and with the same venation, which is very different from that of C. obovata. 



89. Karwinskia Humboldtiana, Zucc. Nov. Stirp. fasc. 1. [in Denkschrift.

• Vitis candicans, Engehn. ined. (which is also the V. coriacea of Shuttleworth, PI. Rugel. exsic, 

 from Southern Florida) is not the same as Vitis Californica, Benth , to which, in PI. Lindh. 2. p. 166, 1 

 was disposed to refer it. Perhaps it may be V. Caribsea, DC.
