104 THE EVOLUTION OF OUR NATIVE FRUITS 



pina), and indistinctly 3-lobed, the apex much shorter than 

 in U vulpima: fertile flowers with very short recurved sta- 

 mens, sterile ones with ascending stamens: cluster small (2 

 to 3 inches long): the berries %-inch or less thick, black 

 with a thin bloom, ripening three weeks later than V. tmlpina 

 when grown in the same place; thin-skinned; pulp juicy 

 and sweet; seeds Bmail. — Brewster county, S. W. Texas, and 

 New .Mexico to Bradshaw Mountains, Arizona. Little known, 

 and possibly a dry-country form of V. vulpima. In habit it 

 suggests /'. Anionic,/, var. glabra, from which it is distin- 

 guished, among other things, by its decidedly earlier-fibwer- 

 ing and larger leaves with coarser teeth and less pointed 

 apex. 



Vitis Longii, Prince. Differs from vigorous forms of V. wlpina 

 in having floccose or pubescenl young growth: leaves deci- 

 dedly more circular in outline, with more angular teeth and 

 duller in color, often distinctly pubescenl beneath: stamens 

 in fertile flowers short and weak and laterally reflexed, those 

 in sterile llowers long and strong: seeds larger. — N. W. Texas 

 and New Mexico. Regarded by French authors as a hybrid, 

 the species V. rupestris, vulpina, candicans, and cordifolia 

 having been suggested as its probable parents. It is vari- 

 able in character. In most of its forms it would be taken 

 for a compound of V. rupestris and J", vulpina, but the latter 

 species is not known to occur in most of its range. It WW 

 very likely originally a hybrid between V. rupestris (which 

 ii sometimes closely resembles in herbarium specimens excepl 

 for its woolliness I, and some tomentose specie- > possibly with 

 /'. Arizonica or V. Doaniana), bul it is now so widely dis- 

 tributed, and grOWS SO far removed from its supposed pa- 

 rents, and occurs in such great quantity in certain B 

 that for taxonomio purposes it musl be kept distinct. It is 

 not unlikely that it lias originated at different places as the 

 product of unlike hybridizations. Late French writers d< 

 uate the jagged-leaved forms as /'. Solonis, and the dentate 

 forms as r. Vuevo ifexicana. This interesting grape 

 found some thirty yean ago by Bngelmann in the Botanic 

 Garden of Berlin, under the name ol I Solonis, without 

 history. Bngelmann guesses Bushberg Cat. ed. 3, 18
