362 AsHE: NOTES ON TREES AND SHRUBS 
thick and broad-leaved form of Celtis laevigata Willd., which has 
developed on these limestone slopes. 
Robinia pauciflora sp. nov. 
slender stems 2— ab mm..thick, light dull tan, 
hispid (on vigorous shoots densely so) with short straw-colore 
oO rely purplish setae. Stipular spines usually wanting 
to eleven (or thirteen) thin, dark green leaflets which are ovate 
or elliptic and full and rounded at both ends, or rarely broadly 
flowers large, 23-25 mm. long, pale bluish-purple with white; 
calyx barely 1 cm. long, the divisions as long as the tube, their 
edges ciliate and like the tube with more or less short pubescence 
mixed with paler larger gland-tipped hairs. Not known to 
fruit. 
This plant is abundant on the mountains immediately across 
the river from Wolf Creek Post Office, Tennessee, in mixed oak 
woods, growing with R. Boyntonii Ashe, which becomes 2 m. 
high, and with R. ped lata Ashe, which is also dwarf and which 
flowers about ten days earlier than R. pauciflora. This is one 
of the plants which has been included with R. hispida L., from 
which it is well separated by its low habit, slender twigs, yellowish 
setae, and few-flowered racemes. 
Robinia albicans sp. nov. 
A shrub, propagating extensively by root suckers, with erect 
5 m. high, or in cultivation becoming 2 m

oblong-obovate, full and rounded at base often abruptly pointed
