SEGREGATES OF RHUS. 127 
Lookout Mountain, Georgia, July, 1898, Albert Ruth, n. 356 
asin U.S. Herb. Perhaps a more pubescent form, with some- 
what doubly lobed leaflets, is Percy Wilson’s n. 155 from Taylor’s 
Ridge, also in the mountains of northwestern Georgia. 
T. QUERCIFOLIUM. Rhus quercifolia, Steud. Nom. 1 ed. 689. 
Habit of the last two, the leaflets quite as strongly lobed, but 
angularly and acutely so; fruits of the largest, in short glom- 
erules or racemes, depressed-globose, polished and nearly glab- 
rous. 
Inhabits the coastal plain, mostly in pine barrens, from Dela- 
ware to Florida; excellent specimens in U. S. Herb. from 
Laurel, Del., Commons; Salisbury, Md.; Chickering; Cape Henry, 
Va., Kearney; Wilmington, N. C. McCarthy. ‘This doubtless 
coastal plant is typical for the var. guercifolia of Michaux. Its 
leaflets are patterned always after the black-oak type, i. e. are 
acutangular, while in both 7. compactum and monticola they 
have sinuate and rounded lobes, imitating the white-oak type 
in that respect, though not in color. : ; 
T. ORIENTALE. Branches stout, strongly angular, ferrugi- 
nous-tomentulose the first season, afterwards glabrate, lenticellate: 
leaflets, large, the terminal one on a short petiolule, broadly 
ovate, cuspidately acute, entire, commonly 4 or 5 inches long, 3 
or 4 in width, deep green on both faces, glabrous above, also 
beneath except in axils of midvein, these strongly hirsute: 
panicles short, divaricately branched ; flowers large, petals not 
nervose as in American species: fruit large, globose; epicarp thin- 
ner than in any American species, fragile, striate, sparsely 
muriculate, setose-hispid about the apex when immature. 
The Japanese so-called Rhus Toxicodendron is in several par- 
ticulars so different from any and all New World species that 
it forms a fair subgenus; yet I can not discover that it has ever 
been indicated as a variety, not to say species; though I can 
hardly see how this neglect was possible, and fear the above 
name may prove a synonym. My type is on sheet 19548, U.S. 
Herb., from Hakodate, 1862, by Maximowicz.
