136 PITTONIA. 
faleate, densely woolly-tomentose marginally rather than 
ciliate. 
Dry foothills along the Cimarron River, southern Colo- 
rado, 29 Aug., 1896, collected by the author. 
LUPINUS AMMOPHILUS. Perennial but not tufted, the 
stems arising singly from an extensive system of rather 
deep-seated horizontal rootstocks; the stem and raceme 
together ? to 2 feet long, but the large raceme mostly longer 
than the leaf-bearing portion, the whole very stout, some- 
what fleshy, and the petioles and basal part of stem rather 
coarsely hirsute with long white spreading or deflexed 
hairs : leaflets 8 or 10, cuneate-obovate to broadly oblanceo- 
late, light-green and glabrous above, sparsely hirsute be- 
neath, 1 to 1} inches long : raceme large and showy ; pedicels 
and gibbous calyx hirtellous: corolla about 5 lines long, the 
petals subequal, the banner a trifle shorter than the wings, 
with a yellow spot in the middle changing to dark-red, the 
petals otherwise purple; keel falcate, the long beak-like tip 
thinly woolly-ciliate: ovaries densely tomentose. 
Sandy bottoms of dry streams at Aztec, New Mexico, 20 
April; also at Los Pinos, Colorado, 18 May, 1899, C. F. 
Baker. A very distinct lupine, bearing no obvious marks 
of near relationship to any other. 
TRIFOLIUM NEMORALE. Caulescent but low, the flowering 
stems only 3 tob inches high, tufted on the branching erown 
of a stout perpendicular root: lowest leaves on petioles 
quite equalling the flowering stem ; leaflets mostly 3, in some 
plants prevailingly 4 or 5, obovate-oblong or broadly ob- 
long, $ to inch long, very obtuse, sharply serrate-toothed, 
bright-green and glabrous above, canescently pubescent be- 
neath, but the indument densest along the margin and 
between the teeth, the leaflet thus appearing almost woolly- 
margined: heads seldom more than 2, often 1 only, nearly 
hemispherical, ? inch broad ; calyx canescently villous, the
