with dark purple anthers and stigmas. Allied, though remotely, to Blepha- 
ripappus, which ought to be referred to the Maprea.—(Named from its mi- 
nute, feathery pappus.) . 
Ptilonella scabra. Blepharipappus scaber, Hoox. Flor. Bor. Am., Vol. L, 
p. 316. 
Has. The prairies of Oregon, east of Walla-Walla. Erect, about a foot high, towards the 
summit dividing into numerous filiform, virgate branches, somewhat corymbose at their sum- 
mits. Leaves numerous, minutely scabrous, linear, somewhat obtuse, attenuated below, sessile, 
from a quarter of an inch to an inch long, scarcely half a line wide. Stem smooth and shining. 
Involucrum and upper leaves glandular and viscid. Sepals oblong-lanceolate, a little hirsute. 
Rays two or three, white, widely dilated, about as long as the involucrum, with filiform, smooth 
stigmas. Discal florets about eight, also white; anthers and stigmas blackish purple. Infertile 
achenium nearly smooth, empty and barren, with a coarser pappus of about twelve filiform fim- 
briate scales. Radial florets sheathed by the sepals to their summits. 
Ozs. As this plant is wholly at variance with the published generic and specific character of 
Blepharipappus glandulosus, 1 have presumed to separate it as a genus.

Madia sativa. 
Haz. In the plains of Oregon towards the sea, particularly on Wappatoo Island, at the outlet of 
the Wahlamet. 
Madia * capitata; very hairy and viscid; leaves linear, amplexicaule; flow- 
ers mostly in terminal clusters. 
Has. With the above, and in the Rocky Mountains, of which, except the inflorescence, it ap- 
pears little more. than a variety. Achenium black, smooth, granulated, rather ea and somewhat

MADARIA. (Decand.) 
-Madaria * racemosa; stem simole erect; flowers axillary, racemose, on ex- 
serted pedicels; leaves narrow-linear, sessile, hirsute, radical serrulate; above, 
with the involucrum, pilose and glandular. 
‘Has. — of — Wahlamet, near the falls. Nearly allied, apparently, to AZ. corymbosa, but 
in a corymb, though sometimes ‘fastigiate. Rays about fifteen, yellow, often
