152 GREENE 



in Georgia, published by Mr. Roland M. Harper last year, 1 it 

 appears to me probable that this zealous explorer of southern 

 fields and woods has, without knowing it, rediscovered this 

 large scarlet-fruited Rhus of Catesby. Mr. Harper says that 

 he found what he took for Rhus] glabra "in a cane-brake on 

 the bank of the Coosa River, in Floyd County, about twelve 

 miles below Rome, Georgia, a veritable little grove of this 

 species, in which many of the specimens were as much as seven 

 inches in diameter and thirty feet tall, with the lowest branches 

 higher up than I could reach." Mr. Harper describes the 

 drupelets of this tree as " bright scarlet," just the color men- 

 tioned by Catesby more than a century ago, as being one among 

 several marks by which R. caroliniana was to be distinguished 

 readily from the then well known R. glabra, the fruits of which 

 are unvaryingly of a dark crimson when mature. 



8. RHUS ATROVIRENS, sp. nov. 



Stout upright shrub, the young branches and lower face of 

 foliage not very glaucous : leaves about 3 dm. long, with 

 unusually stout petiole and rachis, the whole more firm and 

 ascending than in allied species : leaflets about 23 and closely 

 approximate, subcoriaceous, of a dark green above, pale but 

 not white beneath, of only middle size, 5-7.5 cm. long, nar- 

 rowly oblong-lanceolate, subsessile by an obtuse base, the apex 

 subulate-linear, entire, the serratures of the margin, though 

 obscure very numerous, 16-22 on each side : panicle of fruit 

 narrowly pyramidal, 1.5 dm. long, compact; drupelets larger, 

 than in the last, quite rotund, 4 mm. wide, deep crimson as in 

 most species. 



Mountain region of northern Alabama ; type in the National 

 Museum No. 19814, from near Gadsden, 1888, by Gerald Mc- 

 Carthy. Distinguished from one and all the foregoing by its 

 narrow and crowded dark green and rather rigid leaflets. 



9. RHUS PULCHELLA, sp. nov. 

 Branches not stout, angular, glaucous, minutely lenticellate : 



leaves not large, about 2 dm. long, rather long-petioled, of a
