NEW SPECIES OF CERASTIUM. 301 
C. CAMPESTRE. Size and habit of C. occidentale but rather 
more leafy, the cymes more contracted and with more 
numerous flowers, but stem canescently villous below, the 
dense indument strongly deflexed, the upper portion and 
the pedicels with a much less dense and a spreading villosity 
of hairs mostly gland-tipped and very viscid: leaves $ inch 
long, subulate-lanceolate, strongly ascending, rather densely 
appressed-villous on both faces: sepals very acute, hardly 
scarious except at the very apex, appressed-pubescent, not 
viscid, 1-nerved: corolla large, the broad bifid petals of 
nearly thrice the length of the sepals. 
Apparently frequent on the high prairies of British 
America, when it takes the place of the more southerly 
C. occidentale, from which its strong villous pubescence and 
some other characters well distinguish it. Numbers 5,599 
(Cypress Hills, N. W. T.), 4,600 (Indian Head, Assiniboia) 
_and 12,450 (Stonewall, Manitoba), of the Canad. Survey, are 
sheets that perfectly represent the species. 
C. vestitum. Loosely tufted slender stems decumbent, 
often geniculate, 4 to 7 inches high, their leaves short and 
in few pairs, the lowest oblong, others oblong-linear, the 
upper rather broadly lanceolate, less than $ inch long (the 
internodes 1 to 24 inches), acutish, ascending or at length 
spreading, rather densely somewhat villous-pubescent on 
both faces; stem densely and retrorsely white-villous, the 
peduncles and pedicels with a similar though spreading 
indument intermixed with shorter gland-tipped hairs; 
crowded leaves of the short spreading sterile shoots elliptic- 
lanceolate to linear-lanceolate, + to 4 inch long, more spar- 
ingly villous, when very old glabrate: sepals 2 lines long, 
rather broad, abruptly acutish, glandular-puberulent and 
viscid, wholly herbaceous, or scarious at tip: petals thrice 
the length of the sepals: capsule not exserted.
