532 MONOECIA POLYAXDRIA 



2. Q. coccixka, Wangenh. Leaves on long petioles, oblong, deeply 

 •inuate-lobcd, smooth, the lobes divaricate, dentate ; cup subturbinate, 

 conspicuously scaly ; nut roundish-ovoid, Beck, Bot. p. 329. Icon , 

 Mx.f. Sylva, 1. tab. 25^ (fruit, tab. 24.). 



Crimson Quercus, Vulgo — Red Oak. Scarlet Oak. 



S!tem60to90feethigh, and 2 to 3 or 4 feet in diameter, branched above. Leaves 

 4 to 8 inches long, and 3 to G inches wide, deeply lobed, the lobes spreading, sinu- 

 ate-dentate, and setaceously mucronate, the base obtuse, or often somewhat cune- 

 ate, both surfaces smooth, and shining green, with a dense tuft of pubescence in 

 the axils of the nerves beneath (when young the leaves are somewhat pubescent, 

 especially on the margin), finally becoming red, and spotted with deeper crimson; 

 petioles an inch and half to 3 inches long. Acorn roundish-ovoid. 



Hub. Rich, moist woodlands : frequent. Fl. May. Fr. October. 



Obs. This is a fine tree. The wood is much used for Cooper's stuff, kc. and 

 the bark is much esteemed for tanning. I did not distinguish it from the following, 

 when my Catalogue was prepared. 



3. Q, rubra, L. Leaves oblong, obtusely sinuate, smooth; cup 

 saucer-shaped, nearly smooth ; nut oblong-ovoid. Beck, Bot. p. 329. 

 Icon, Mx. f. Sylva, 1. tab. 28. 



Q. rubra maximal Marsh, Arbust. p. 122. 



Red Quf.rccs. Vulgo — Red Oak. Spanish Oak. 



Stein 00 to 90 feet high, and 2 to 4 feet in diameter, branched above. Leaves 4 

 to 8 or 10 inches long, and 3 to 6 inches wide, oblong, or often somewhat obovate, 

 obtusely sinuate-lobed, the sinus shallower than in the preceding species, the 

 lobes dentate, and setaceously mucronate, the base of the leaves rather obtuse, 

 both surfaces smooth, with tufts of pubescence in the axils of the nerves beneath ; 

 petioles 1 to 2 inches long. Acorn rather large, oblong-ovoid, in a flat or shallow 

 saucer-like ct/p, of which the scales are so compact as to present a 6moothish 

 and nearly even surface. 



JIab. Hilly woodlands : frequent. Fl. May. Fr. October. 



Obs. The wood of this is also used for Cooper's stuff*, kc and tho bark is in 

 demand by the Tanners. I think both this and the preceding are often called 

 Spanish Oak; but that name seems properly to belong to another species (vi«. 

 Q./alrata, Mx. or Q. elongata, Willd), which has not yet t*en observed in this 

 County,— although it has been found in the adjoining County of Deleware, and is 

 abundant in the Counties of New Castle, and Cecil, on the South of us. 



4. Q. palustris, Mx. Leaves oblong, deeply sinuate-lobed, smooth, 

 the lobes divaricate, dentate, the sinuses broad ; cup saucer-shaped ; 

 nut subglobose, small. JBech, Bot. p. 329. Icox, Mx. f. Sylva, 1. 

 tab. 27. 



Q. rubra ramosissima. Marsh. Arbust. p. 122. 



Marsh Quercus. Vulgo — Pin Oak. Water Spanish Ouk, 



Stem 40 to 60 feet high, and 1 to 2 feet in diameter, with numerous rather slender 

 horizontal or drooping branches, which are frequently very knotty. Leaves 3 to 

 5 or 6 inches long, and 2 to 3 or 4 inches wide, deeply lobed, the lobes rather 

 narrow, diverging, or divaricate, acutely sinuate-dentate near the apex, and seta- 

 ceously mucronate, the sinuses wide or open, the base of the leaves obtuse, or 

 often cuneately tapering, both surfaces smooth, except a tuft of pubescence in 

 the axils of the nerves beneath, the upper surface green and shining ; petwles 1
