one-half by the turbinate or deeply saucer-shaped cup 

 gradually narrowed at the base, with closely appressed, 

 brown-pubescent scales. S. Mich, to Man. and Iowa.

6. Kelloggii, Newb. (Q. californica, Coop.). CALI- 

 FORNIAN BLACK OAK. Fig. 3311. Tree, occasionally to 



3308. Leaves of Quercus 

 coccinea X- No. 3. 



100 ft., with stout spreading branches forming an open, 

 round-topped head: Ivs. divided about to the middle by 

 wide sinuses into usually 7 oblong, toothed lobes, pubes- 

 cent when young, at length glabrous and glossy above, 

 yellowish green and glabrous or floccose beneath, 3-6 

 in. long: fr. short-stalked; acorn ovoid or oblong, 

 mostly rounded at the top, 1-1 ^ in. long, embraced 

 about one-third or one-half by the deep hemispherical 

 glabrous cup. Ore. to Calif . S.S. 8:416. G.F. 9:145. 



7. vel&tina, Lam. (Q.tinctoria, Bartram). BLACK OAK. 

 YELLOW-BARK OAK. Figs. 3305, 3306, 3309. Tree, to 

 80, sometimes to 150 ft., with rather slender branches, 

 spreading gradually into a narrow, open head: bark 

 very dark brown, inner bark orange: Ivs. pinnatifid to 

 or beyond the middle, with 7-9 broad toothed lobes, 

 dark and dull green above, brownish pubescent beneath 

 at first, glabrous at length, except in the axils of the 

 veins, 4-10 in. long: fr. short-stalked; acorn ovoid, J^-l 

 in. long, embraced about one-half by the hemispherical 

 densely pubescent cup. Maine to Fla., west to Minn, 

 and Texas. 8.8.8:414,415. Em. 1:160. G.F. 5:55. 

 This species hybridizes with Q. coccinea, Q. rubra, 

 Q. imbricaria and Q. Phellos (Q. heterophylla, Michx.). 



Tree of rapid growth, 

 less beautiful than 

 the preceding species, 

 but the wood is more 

 valuable; it flourishes 

 even in rather dry 

 soil, and the foliage 

 turns dull red or 

 orange-brown in fall. 

 Var. missouriensis, 

 Sarg. Lvs. with a 

 permanent rusty 

 pubescence beneath: 

 cup-scales tomentose.

8. falcata, Michx. (Q. digitdta, Sudw. Q. cunedta, 

 Auth., not Wang.). SPANISH OAK. Tree, to 70, rarely 

 to 100 ft., with stout spreading branches forming an 

 open, round-topped head: Ivs. deeply pinnatifid, with 

 5-7 entire, acute and often falcate lobes gradually nar- 

 rowed from a broad base and spreading at nearly right 



separated by broad sinuses, drooping, dark

green and glabrous above, tawny or grayish pubescent 

 beneath, 3-8 in. long: fr. short-stalked; acorn subglo- 

 bose, J^in. high, embraced one-half by the turbinate 

 cup. N. J. to Fla., west to Mo. and Texas. S.S. 8:420. 

 G.F. 8:104. F.E. 29:943. Handsome, with pecu- 

 liarly distinct foliage, but not quite hardy N. It 

 appears that the original description of Q. rubra, 

 Linn., applies to the Spanish oak (see Sargent in Rho- 

 dora 17:39); therefore, under a strict application of 

 the rule of priority, Q. falcata, Michx., ought to be 

 called Q. rubra and the tree heretofore known as Q. 

 rubra ought to be known as Q. borealis, if var. ambigua 

 is not considered specifically distinct; otherwise it 

 ought to receive a new name. The name Q. borealis 

 applies more strictly to the northern form (Q. rubra var. 

 ambigua), while the more southern form becomes Q. 

 borealis var. maxima, Sarg. 



9. pagodaefolia, Ashe (0. falcata var. pagodaefolia, 

 Ell.). SWAMP SPANISH OAK. Tall tree, sometimes 120 

 ft. high, with wide-spreading branches forming a broad 

 open head, but narrow in the forest; branchlets tomen- 

 tose: Ivs. deeply pinnatifid, with 5-11 entire, acute, 

 spreading lobes narrowed from a broad base and often 

 falcate, dark green and lustrous above, white-tomen- 

 tose beneath, 5-8 in. long: fr. short-stalked or nearly 

 sessile; acorn ovate to subglobose, little over 3^in. 

 across, inclosed about one-half by the turbinate cup; 

 scales loosely imbricate, pubescent except on the mar- 

 gin. Va. to Fla., west to S. 111. and Ark. S.S. 14:772. 

 Handsome and valuable timber tree; about as hardy 

 as the preceding species. 



10. ilicifdlia, Wang. (Q. Bdnisteri, Michx. Q. nana, 

 Sarg.). BEAR or SCRUB OAK. Intricately branched, 

 spreading shrub to 10 ft. high, rarely small tree to 20 

 ft.: Ivs. pinnately lobed, with usually 2 broad triangu- 

 lar lobes on each side, dark green and glabrous above, 



3310. Quercus Schneckii. 



No. 4. 



whitish tomentulose beneath, 2-5 in. long: fr. short- 

 stalked; acorn globose-ovoid, Hin. or less high, embraced 

 about one-half by the saucer-shaped cup. Maine to 

 Va., west to Ohio and Ky. S.S. 8:424. Em. 1:170. 

 Growing naturally on dry rocky soil and forming 

 dense thickets; it may be used for covering barren 

 rocky ridges and hillsides. Hybrids with Q. coccinea, 

 Q. velutina, Q. marilandica, and Q. Phellos are known.
