ASTER ATROVIRENS 147 
fewer sinuses, much more taper bases to the middle and upper 
caulines, and more naked inflorescence more thoroughly simul- 
taneous in blossom (though not so completely simultaneous as in 
A. fragrans). 
From the other principal long-leaved congener of deep woods, 
4. tenebrosus, A. atrovirens is distinguished, among numerous 
other characters, partly by its smaller denser heads, lack of pro- 
liferation and of large acute bracts, and by its different leaf-form 
and inflorescence. 
— Fimbriation sometimes occurs ; split rays were found in all 
the plants of one community at ifudiob Heiphts, N ]5 5e. 12, 
'98 ; these were unusually vigorous large-leaved plants, otherwise 
typical, and with the usual seedy condensed-dome inflorescence.

6. Aster erectus sp. nov. 
Small dark-green plants, with short ovate-acute leaves, mod- 
erate teeth, broad pale-margined obtuse bracts, filiform pedicels, 
crimson disks, and suberect rays crowded in a tangled single-bunch

Name, L., because the rays are apt to remain for a long time suberect. 
Fic. 8 (= PLATE 4, A), from plant of Bryn Mawr Park, vic. N. Y., Oc. 2, 96;
