half as long as the tube. ‘lhe leaves are fully as much divided as 
in the former, but the plant is more woolly. 
“ LapputaA AMERICANA (Gray). 
Echinospermum deflexum var. Americanum Gray, Proc. Am. 
Acad: t7< 224. 
I think this is quite distinct from the European L. deflexa. 
The species of the Mississippi Valley and westward is a much larger 
plant, with a many-flowered divergently paniculate-branched in- 
florescence and broadly oblanceolate leaves. The European J. 
_ deflexa has almost linear leaves. L. Americana was collected by 
the author at Deer Lodge, Mont., in 1895 (no. 2775), a point 
much further west than the supposed range of the species. 
. ERIGERON OBLANCEOLATUS, 
Stem from an apparently biennial root, 3-5 dm. high, striate, 
finely strigose, branched above; basal and lower leaves oblanceo- 
late, tapering into a winged petiole, pointed, the margins ciliolate 
and with a few small but sharp teeth; stem-leaves linear, diminish- 
ing upward, the uppermost bract-like; heads 1-3, comparatively 
large, 15-25 mm. in diameter and about 10 mm. high; bracts 
40-50, narrowly linear, acuminate, strigose; rays numerous, gen- 
erally about 100, very narrow. 
In the size and form of the head and bracts it most resembles 
E. speciosus and E. subtrinervis. In general habit it resembles some- 
what Z. gladellus Nutt., but differs by the much larger heads, the 
toothing of the lower leaves and the weak root system, which indi- 
cates a biennial, or a perennial by biennial offsets (the specimens 
show no stolons). In the latter case the plant should be placed 
nearest E. Philadelphicus, from which it is easily distinguished by. 
the thin narrow leaves, the form and size of their teeth and by the 
few and larger heads.
