P. huachucae, P. villosissimum, P. linearifolium, P. depauperatum, P. 
sphaerocarpon, P. columbianum and P. tsugetorum, the last being the 
exceptionally hairy form once described as P. lanuginosum var. 
siccatum.! Of the above, P. albemarlense and P. implicatum are the 
more abundant, but all the other species mentioned are well represent- 
ed, no species, of which merely one or two plants were seen, being 
included in the list. Specimens of P. albemarlense and P. tsugetorum 
have been verified at the United States National Museum by Prof. 
A. S. Hitchecock.—R. W. Woopwarp, New Haven, Connecticut. 
RaNuNcuLUs Pumsumn iN lowa.—Last July, while doing field 
work along the east shore of Spirit Lake in northern Iowa, I had the 
good fortune to find an interesting aquatic crowfoot, namely Ranun- 
culus Purshii Richards, which does not appear to have been hereto- 
fore recorded from the state. It was growing quite plentifully in 
what had been a small pond, but at that time was entirely dried up, 
though the soil was still somewhat moist. "The plants, though weak, 
all grew quite erect and were from six to ten inches high, the small 
flowers being a very bright yellow. Having never seen a specimen 
of R. Purshii I sent some material of the plant to Dr. B. L. Robinson, 
who kindly examined it and pronounced it to be this species. Its 
previously recorded range is thus extended several hundred miles 
southward in the Mississippi Valley.—R. I. Crarry, Curator, Iowa 
State College. 
A RARE VARIETY OF VITIS LABRUSCA.—About the first of October 
of the present year (1920) I observed on sale in public market in New 
Bedford two varieties of our native grapes: Vitis labrusca L. One 
of these was of the usual dark purple color but the other was entirely 
green. The purple colored grapes were not wholly ripe but very 
nearly so, this being the usual condition of such grapes when used in 
the household for making grape jelly. 
I asked the salesman what the unripe green grapes were used for, 
there being about half a bushel of this variety. He replied that the 
green grapes were ripe and sweet and used for the same purpose as the 
purple ones. I learned that these green grapes were brought in by a 
‘North American Panicum, Hitchcock & Chase, Contrib. U. S. Nat. Herb. xv. 
245 (1910).
