 /"Creek and Live Oak Crcck, Western Texas, May ; also between the Limpio and 

 tbe Kio Grande. (922.) — The specimens are loaded with the fruit, which has been 

 described in thc account of Mr. Wrighfs former collection. 



Karwinskia IIumboldtiana, Zucc. ; Gray, Pl. Wright p. 32. Limestone hills j 



in the Big Bend of the San Pedro Eiver, Western Texas ; July. (1346.) 



Adolphia infesta, Meisner; Gray, Pl. Wrlght l. c. Mountain valleys between 

 the Limpio and the Eio Grande, June ; in flower. (923.) 



Frangula Californica, Gray, Gen. III. 2. p. 178; var. tomentella. Ehamnus 

 tomentellus, Betith. Pl. Hartw. p. 303. Ojo de Gavilan, beyond the copper mines, 

 New Mexico ; Aug. (924.) " Shrub 4 to 6 feet high." — In tbiese specimens the 

 leaves are glabrous and bright green above, even when young, but are clothed be- 

 neath, as are the branchlets, with a fine and soft whitish pubescence. They are 



mostly serrulate, as they 



my specimen of Hartweg's No. 1686. From 



L 



Fremonfs Califomian collection, Dr. Torrey has specimens still more tomentose, 

 even on both sidcs of the leaves ; but I think that all these are merely varieties 

 of Hooker's Ehamnus oleifolius, which was earlier published by Eschscholtz, under 

 the name of Ehamnus Californicus. 



Sageretia Michauxii, Brongn. ; Gray^ Gen. III. 2. t 166. Eocky banks, east 

 of Santa Cruz, Sonora ; Sept. (925.) — The specimens, which are sparingly in 

 flower, appear to agree in all respects with those from Florida. I am not aware 

 that this species has been yet observed at any intermediate station. 



Ceanothus Greggii (sp. nov.) : divaricato-ramosissimus ; ramulis tomentoso- 

 puberulis ; foliis confertis ellipticis oblongisve integerrimis coriaceis crassis nniner- 

 viis glabellis subtus leviter penninerviis primum tomentulosis (3-5 lin. longis) ; 

 pedicellis pubescentibus (demum glabratis) flore albo paullo longioribus. — (Battle- 

 field of Buena Vista, Gregg ; in flower.) Side of mountains near Frontera, New 

 Mexico, July ; in fruit. — Shrub 2-5 feet high, with very rigid branches. Pedicels 

 shorter than the leaves. Flowers small. Fruit about 2 lines in diameter. — I have 



■ 



only poor specimens of this species. It bears considerable resemblance to small- 

 leaved forms of C. cuneatus, Nutt ; but the leaves are not narrowed towards the 

 base, and the pinnate veins underneath are obscure.
