ous, the latter from scarcely equalling to somewhat surpass- 
ing the former; herbage glabrous and both faces of the 
leaves closely puncticulate: earliest and small foliage mostly 
rounded, obtuse, subcordate, as broad as long, those devel- 
oped along with the corollas from subcordate-deltoid to sub- 
hastate-triangular and even triangularly lanceolate, 14 to 2 
inches long, remotely and sometimes obscurely crenate-ser- 
rate, the petioles often not longer than the blade: sepals ob- 
long-lanceolate, obtuse, their margins rarely naked, often 
more or less ciliolate: petals with obovate, obtuse blade, 
violet or paler and sometimes white, three of them densely 
bearded with ‘rather long slightly clavate hairs: late and 
apetalous flowers short-peduncled, horizontal and at least 
partly subterranean. 
A very well defined species, known to me only from Mis- 
souri. Its very distinctly trigonous foliage led me at first to 
refer it to V. emarginata notwithstanding certain discrepan- 
cies, especially its larger corollas, somewhat ciliate sepals, 
etc.; but later specimens show distinctly the depressed or 
partly buried apetalous flowers. My specimens are from 
Mr. B. F. Bush, Leeds, 19 April, 1895, Courtney, 10 May, 
1898, and 30 April, 1899, and from Kenneth Mackenzie, In- 
dependence, 24 April, 1898 and Randolph, 23 April, 1899. 
Some New or Critica, RANUNCULI. 
R. uncuicutarus. Stems solitary, a foot high more or 
less, from a dense fascicle of short thick and tapering white 
and glabrous roots: radical leaves 1 or 2 only, erect, ellip- 
tical or obovate-elliptic, entire, or remotely and obscurely 
denticulate, acute, 3-nerved, 2 or 3 inches long, on petioles 
as long or longer; cauline similar but narrower and short- 
petioled : flowers 2 to 4 in the smaller plants, twice as many 
in the larger, each terminating a long naked puberulent 
peduncle: sepals thin, narrow, some only broadly oblance-
