regularly goffered along the secondary and ternary veins; 

 teeth in one series, wide, indentations shallow and obtuse ; 

 petiolar sinus deep, slightly open ; upper-face light lustrous 

 green, with disseminated patches of araneous hair ; under- 

 face duller green, with well-defined veins covered with a 

 number of stiff brush-like hairs. 



The Late Doaniana differs from the above form by its very 

 marked Mustang characters; it has fluffy tomentum even 

 on the lignified canes. Leaves often tri-lobed, -vaguely 

 goffered, with margins sometimes curved underneath, under- 

 face regularly covered with numerous short araneous hairs ; 

 teeth wide, well defined. 



Munson found a hybrid in the wild state, on the banks of 

 the Red River, which he considered to be a Cinerea X Novo- 

 Mc.vicana, bearing many points of resemblance to Doaniana ; 

 according to him, it has a large and very vigorous trunk; 

 its leaves recalling those of Novo-Mexicana, but being less 

 thick and more tomentose. This hybrid has not been intro- 

 duced or experimented upon in France. Finally, amongst 

 other hybrids of this group, we mention Solonis X Riparia 

 No. 1616 and 16/5, of Couderc; having a resistance to 

 chlorosis equalling that of Solonis, and, according to Couderc, 

 having a greater resistance to phylloxera; the 1615 is the 

 most vigorous. 



Hybrids of V. Candicans and V >Estivalis; of 

 V. Candicans and V. Cordifolia; of V. Candicans and 

 V. Cinerea. The ^stivalis X Candicans are scarce; 

 Millardet only mentions one form. The Cordifolia 

 X Candicans and Cinerea X Candicans are rather 

 numerous, in the wild state, in the north of Texas ; 

 they are generally vigorous in the rich alluvials of 

 river banks; they have not been introduced or experimented 

 upon in France. Their procreators may have transmitted 

 to them a great difficulty of rooting from cuttings, and 

 a feeble, resistance to chlorosis; but have endowed them 

 with a large trunk and great vigour; their resistance to 

 phylloxera may be small, as is the case in all other hybrids 

 of V. Candicans. The Cordifolia X Candicans would offer a 

 greater guarantee of resistance. 



Hybrids of V. Lincecumii and V. XEstivalis: of 

 V. Lincecumii and V. Candicans; of V Lincecumii 

 and V. Cinerea; of V. Lincecumii and V. Cordifolia. 

 These various groups of hybrids are very numerous,
