ELISHA MITCHELL SCIENTIFIC SOCIETY. a, 
tipped with a short, stout mucro, cordate or subcordate 
at base, more or less pubescent when young, soon smooth. 
Racemes axillary, nodding or drooping, 3-5 flowered, 4-5 
em long, one-fifth to one fourth the length of the leaves, 
peduncles usually hispid. Flowers purple-blue in the 
bud, becoming on expansion deep purple or red-purple, 
but lighter-colored at the base, when open 2.5cm or more 
long; blade of wing projecting beyond point of union with 
claw, so as form a narrow but deep sinus between them; 
each division of keel oblong, abruptly contracted into the 
claw. Calyx 8-10mm long, the 4-7mm long acuminate 
lobes much longer than the short broad generally hispid 
tube. Pod short, steut, few-seeded, glandular-hispid. 
A low straggling shrub, 1-3 feet in height. It occurs 
from Virginia to Georgia and Alabama’ in and near the 
mountains. In tke mountains it is for the most part con- 
fined to the crests and dryer southern flanks of ridges, 
and is not uncommon. Its altitudinal distribution 1s from 
300m to 1500m. It seems to pass gradually into the low- 
country form which is nearly destitute of bristles and 
more or less pubescent. 
Robinia Boynlonii is separated from fF. hispida Li. by 
its greater size, smooth pod, oblong leaflets, many-flow- 
ered racemes, short calyx-lobes and smoothness. 
From Fr. v7éscosuw Vent. it is separated by having only 
about one-half the number of leaflets, a smooth pod and 
the absence of viscid secretion. 
In many characters it is nearly allied to A. Pseudaca- 
cia lu: The leaflets are about the same number, twigs 
and pods are smooth; but the flowers are rose-colored 
and smaller than in A. Pseuwdacacia and no stipular 
spines are developed. 
Since the above was put iri tvpe I find that Hodznza 
Boyntonii has been distributed by the Biltmore Herba- 
rium, but without a name, as No. 3268: Near Highlands, 
Macon county, N. C.
