» Aster eriocaulis sp. nov. 
Perennial, with a rootstock ; stems. about 8 dm. high, leafy, 
more or less villous, especially above, purplish ; stem-leaves lan- 
ceolate, 3-7 cm. long, ciliolate on the margins, otherwise glabrous, 
more or less auriculate-clasping ; inflorescence a round-topped 
panicle ; involucres 8 mm. high, 10-12 mm. broad ; bracts linear, 
acute, more or less ciliate, in 2-3 series, with green midrib and 
lanceolate green tips, or the outermost almost wholly green; rays 
purple, 8-1o mm. long ; achenes sparingly hirsute-strigose. 
This species is perhaps most nearly related to Aster loncho- 
phyllus but differs in the longer villous pubescence of the stem, 
the more or less clasping” leaves, less imbricated and not purple- 
tinged bracts. In general habit and leaf-form it resembles some- 
what A. /essicae, but differs in the glabrous leaves and narrower 
glabrous bracts.

- Aster subcaudatus sp. nov. 
Perennial, with a creeping rootstock ; stem 3-6 dm. high, more 
or less purple, glabrous below, with villous or pilose peduncles 
and lines above; lower leaves petioled, 1-2 dm. long ; blades lance- 
olate, 4~10 cm. long, often sparingly dentate with ascending sharp 
teeth, dark green, glabrous, ciliolate on the. margins ; upper leaves 
sessile, linear-lanceolate, attenuate ; panicle open, with rather few 
heads ; involucres 7-8 mm. high, about 12 mm. broad; bracts linear- 
subulate, in 2 or 3 series, but nearly of the same length, attenuate, 
the inner almost caudate, only slightly white-margined below ; 
rays purple, about 1 cm. long ; achenes nearly glabrous, 
The type was determined as Aster Fremontit (?), but is evi- 
dently distinct ; differing from that species as well as its relatives, 
A. occidentalis, A. ciliomarginatus, etc., in the narrow attenuate 
bracts. It is alsoa taller plant with a tendency to having dentate 
leaves. If one should use Piper’s key in his Flora of Washington 
it would fall under A. occidentalis Nutt. The latter, as described 
in Gray’s Synoptical Flora, has well-imbricated bracts, of which 
the outer are shorter; but neither the present species nor Gray’s
