tinct petiole one-eio*hth of an inch long-. The ve- 

 nation shows the dichotomous forking- so charac- 

 teristic of nig-ra. The upper bud scales are pubes- 

 cent. The leaves are thick and stiff. In the fall 

 they first turn yellow and then dull brown and persist. 

 They are small trees, 6 to 10 feet in heig'ht, with droop- 

 ing" branches and roug^h bark. Only a few nuts could 

 be found, only a few trees fruiting-. These were oval 

 and black ribbed, somewhat largfer than the nuts of 

 cinerea, and had disproportionately enlarg-ed hemispher- 

 ical cups, covered with coarse pubescent scales. The 

 trees in November have the gfeneral appearance of 

 nig-ra after the leaves have turned. Perhaps ten such 

 trees were seen, all in the neigfhborhood of the coast. 



O. aqiiatica^ Q. nigra. — The leaves are 2 to 4 inches 

 long-, 1.5 to 3 inches broad; broadly ovate or deltoid in 

 outline, broadest above the middle. They are scolloped 

 or slig'htly 3 (rarely 5) lobed and short bristle tipped; 

 sessile and usually acute at the base. Above they are 

 g-labrous and also below, except in the axils of the prin- 

 ciple veins where there are tufts of coarse hair. The 

 leaves are thick and firm, and on November 24, were 

 mostly g-reen or the lemon yellow which withering" 

 leaves of aquatica turn. The venation is that of nig-ra. 

 The buds are small but hairy at the summit as are 

 those of nig-ra. The twig-s are slender and warty. 

 The pubescent — scaled cup is hemispherical, and en- 

 closes one-half of the ovate, obscurely ribbed nut. 

 The nuts are imperfect, often with the fertile embr^^os 

 but slig-htly more developed than the abortive ones. 

 The branches are drooping-; the bark is slig-htly gray. 

 Only a sing-le tree was seen, about 20 feet in heig"ht 

 and with a broad spreading- crown. Imperfect nuts 

 and cups were abundant, the latter usually remaining- 

 on the tree.
