scales glabrous, chestnut-brown: petioles 1-3 cm. long, 

 slender, glabrous ; leaf-blades 5-10 cm. long, broadly ovate in 

 outline, lobed deeper than half-way to the midrib, glabrous 

 and shining on both sides or hairy on the veins beneath, cu- 

 neate or truncate at the base ; lobes 5-9, triangular, rarely 

 toothed, acuminate and spinulose-tipped at the apex : fruit 

 subsessile : cup hemispheric, 9-12 mm. broad; acorn ob- 

 long-ellipsoid, 12-14 mm - l° n g- 



This is the only red oak found in the region. It differs 

 from J^. rubra in the deeper and wider sinuses of its smaller 

 and more glossy leaves and in its deeper, paler and more 

 tomentose cups. It does not really belong to the region, its 

 home being Central Texas, but extends to the Limpio Moun- 

 tains in the western part of that State. 



Professor Sargent gave the range of this species as ex- 

 tending from Indiana and Florida to Arkansas and Texas. 

 This depended upon the fact that he included in J?. Tex- 

 ana a quite distinct species.* In the true J^. Texana the 

 lobes of the leaves are distinctly triangular and mostly 

 entire and the cup hemispheric or even slightly turbinate at 

 the base, while in the other species the lobes are more oblong 

 and coarsely toothed and the cup is shallow, saucer-shaped. 

 Professor Sargent's Plate 411 illustrates both species. Figs. 

 1-4 and 6 belong to J^. Schneckii, and 5 and 7 to J^. Texana.

* This has been segregated from O. Texana by Dr. Britton and character- 

 ized as follows : 



Quercus Schneckii Britton. A forest tree similar to Q. rubra and Q. pa- 

 lustris. Bark reddish-brown with broad ridges broken into plates ; leaves 

 mostly obcordatc, bright green and shining above, paler and with tufts of 

 wool in the axils beneath, 0.5-1.5 dm. long, truncate or broadly wedge-shaped 

 at the base, deeply pinnatifid into 5-9 oblong or triangular lobes, which are 

 coarsely few-toothed and bristle-tipped ; styles short : cup saucer-shaped, 

 10-16 mm. broad, its scales appresscd ; acorns ovoid, 1-2.5 cm. long, three 

 times as high as the cup. Ohio and South Indiana to Iowa, Missouri, Florida 

 and Texas, April-May. Acorns ripe in Sept. -Oct. [Q. Texana Sargent 

 in part, not Buckley ; 111. Fl. fig. 1230].
