1923] Ashe,—Notes on Trees and Shrubs. 181 
From present information it appears that a large number of these 
species do not fruit, or if so only when wild and then seldom. Bean! 
ascribes this to absence of pollen. Large groups of plants, however, 
if exclusively of vegetative origin, are properly regarded as a single 
plant so far as cross-fertilization is concerned. 
The description of R. grandiflora was largely drawn from fruiting 
specimens collected July, 1900, on Grandfather Mountain, N. C., but 
it seems desirable to revise the description so as to limit it to this 
plant which has now been cultivated for two years as well as again : 
studied growing wild at Wiseman’s Bluff, Linville Mt. and at the 
type locality. 
RoBINIA GRANDIFLORA Ashe (Journ. Mitchell Sci. Soc. 37: 176. 
1922). A shrub .6-1 m. high or in cultivation becoming 1.6 m. 
. high, with peduncle, calyx, rachis and petiole more or less hispid 
especially on young plants and with vigorous shoots densely hispid; 
but on old plants the twigs and shoots may be nearly or quite free of 
setae. Young twigs especially on old plants, peduncles and leaflets 
on unfolding closely grayish pubescent as well as petioles and rachises. 
Leaflets 9—15, elliptic or broadly ovate, rounded at the ends, 1.8-3.1 
mm. wide, pale beneath when mature. Flowers about 20 mm. long, 
pale rose or pale purplish-rose with white, 4-8 in a raceme, peduncles 
pubescent and hispid, on young plants densely hispid, on old ones 
sparingly so; calyx 8-10 mm. long, the lobes long-acuminate, much 
inflated in fruit, hispid, on very young plants densely so and more or 
less pubescent, part of the hairs being sometimes gland-tipped. Leaves 
bronze on unfolding. 
Linville Mountain, N. C., where not uncommon or at Wiseman's 
Bluff very common and associated with R. speciosa. Flowers from 
a cultivated plant. 
Robinia speciosa, sp. nov. (R. grandiflora Ashe, in part). A much 
branched shrub propagating by root-suckers, 1-1.5 m. high or in 
cultivation becoming 2 m. high; branchlets dull tan, stipular spines 
wanting. Young shoots covered with short pale brown pubescence 
often becoming glabrate, vigorous shoots hispid with pale setae. 
Leaves of 9-13 ovate or elliptic-ovate,abruptly pointed or obtuse 
leaflets, 22-34 mm. wide, on unfolding deep bronze and covered 
beneath with pale gray or yellowish-gray pubescence as well as 
petiole and rachis. Flowers large, 21-24 mm. long, bright rose and 
pink with white, in 5-8-flowered racemes; calyx broad, 8-10 mm. 
long, brownish-gray pubescent and sparingly hispidulose, the 4 mm. 
long lobes abruptly acuminate; peduncles 3.5-6 cm. long, pubescent 
and usually slightly hispidulose.
