NEW OR CRITICAL SPECIES OF ACER. 11 
flowered and subcampanulate: achenes scarcely 4 lines long, 
almost columnar, only slightly narrower from the middle up- 
wards, but this portion vacant, the whole of a light brown 
approaching straw-color, the usual ribs obsolete and the whole 
surface smooth, the outer ones more shortly and densely villous 
than in other species: pappus fully 5 lines long, the dull dark- 
brown paleæ lanceolate (also cymbiform), strongly appressed- 
villous but only on and very near the very broad midvein, the 
_ awn longer than the palea, rather rigid, nearly barbellate. 
Near Antioch, Calif., Mrs. Curran, 1886, the type in Herb. 
Calif. Acad. Some pretty genuine M. attenuata was collected 
at the same time; but the robust habit and very peculiar smooth 
achenes mark this rather strongly. 
M. ParvuLa. Dwarf, as compared with M. attenuata ; only 
2 or 3 inches high, but with long cylindric involucres large in 
proportion: achenes light-brown, 3 lines long, almost cylindric, 
the only slightly narrower upper and vacant portion of the peri- 
carp comparatively short; none villous, all with serrulate-scab- 
rous striae; pappus white, the narrower cymbiform palea densely 
white-villous, surmounted by a subplumose awn of about its own 
length. 
Hill tops near Antioch, Calif., Mrs. Curran, 1883 or 1884. 
The plant was at first named by me, in the Calif. Acad. herba- 
rium as a variety of M. attenuata. 
M. Parisuir, Greene, Bull. Calif, Acad. ii, 46, in part, and as 
to the plant of Parish only. As to the habit, involucre, ete. 
much like M. attennata, but achenes only 23 lines long, scarcely 
narrower at summit (though not filled by the seed), and almost 
colummar; lanceolate paleæ of the pappus glabrous, very dark- 
colored, as long as the achene itself, and attenuate toa much, 
shorter awn, this little more than a line long. 
The originals of my former M. Parishii, when all their char- 
acters have been duly considered, are seen to represent three 
species. Dr. Parry’s specimen is allied to M. Bigelovit, if not, 
indeed, a form of that species; and my own specimens from
