38 BOTANICAL GAZETTE. [ Feb. 
Mr. W. J. McGee, of the party, from a swamp in a pine wood, 
two miles north of Rowanty creek. 
Jatropha urens, var. stimulosa, becomes a common plant 
from the Rowanty creck southward. 
Tephrosia spicata was found at Bolling’s Bridge, over the 
Nottaway, as a kind of vetch in the fields. 
Desmodium strictum, one or two young flowering plants, was 
also collected in the vicinity of Bolling’s Bridge 
reweria humistrata was found on the Nottaway, in a dense 
pine wood, trailing and climbing over the smaller undergrowths 
and blooming profusely, a delicate and handsome vine. 
Elephantopus tomentosus, which replaces E. Carolinianus of 
the northern districts, was first seen in the Nottaway valley, and 
became quite frequent as we traveled southward. 
Cyrilla racemiflora was first seen on Falling Run, about three 
miles south of Hicksford, and once more near the state line in 
North Carolina. It was unfortunately then (August 18) out of 
er. 
Pluchea camphorata was seen between the Meherrin and Fon- 
taine’s creek. 
Arundinaria macrosperma, which occurs sparingly on the 
Nottaway, forms a constant feature of the low ground along 
Fontaine’s creek, near the state line, and is abundant from that 
point southward. 
The principal new forms noted in North Carolina, which 
were not seen in Virginia, were Senecio tomentosa, Baptisia vil- 
losa (in fruit), Carex glaucescens (I once collected this at Nor- 
folk, Va.), and Amorpha fruticosa. 
After our return to Washington, the reconnoissance was ex- 
tended to Maryland. 
Eupatorium serotinum, which has never been found in the 
District of Columbia, is one of the most abundant plants along 
the Patuxent, above and below Marlboro, a distance of less than 
twenty miles. 
Centrosema Virginianum was also found growing in the deep 
sands that now cover the wide tract east of the Patuxent, across 
which the bed of that stream has been shifting since the tertiary 
epoch.
