ROSACEAE. 
NEVIUSIA. 
(Family Rosaceae): 
Loosely branched shrubs re- 
sembling Spiraea and Physocar- 
pus: deciduous. Twigs slender, 
long, somewhat zig-zag, decur- 
rently ridged from the nodes: 
pith relatively large, rounded, 
white, continuous: medullary rays 
rather coarse. Buds rather small, 
solitary, sessile, ovoid, .ascending, 
with about half-a-dozen some- 
what keeled or striate scales. Leaf- 
scars alternate, round-cordate, 
slightly raised and decurrent: 
bundle-traces 3, more or less 
doubled: stipules persistent as 
small scales from the decurrent 
ridges above the leaf-scar. 
Neviusia is intermediate in ap- 
pearance between Spiraea and 
Physocarpus. It is one of the 
very local genera and consists of 
a single species which was made known to botanists and in- 
troduced into cultivation by the reverend Dr. Nevius of Ala- 
bama, who sent to the Missouri Botanical Garden the plant 
from which the accompanying sketch was made. 
Winter-characters of N. alabamensis are given by Schnei- 
der, f. 137. 
Twigs golden-brown, puberulent: buds glabrate. 
N. alabamensis.
