1909] Moore,— Hairy-fruited Rhus Toxicodendron 168 
colored, subglobose, glabrous or nearly so," that is hairs, if present at 
all, which is rare, few and small. In the Bristol plant, however, 
there are numerous and conspicuous soft hairs, a fact which is very 
interesting because it is the characteristic of the fruits in most of the 
genus to be covered with hairs of some sort. Although a smaller 
berried plant with shorter hairs on the fruit occurs in Florida, which 
seems to be a distinct variety, if not species, among plants which can 
with positiveness be determined as Rhus Toxicodendron the present 
specimen seems to be altogether unique. 
Ruvs ToxicopENpRON L. f. malacotrichocarpum A. H. Moore, 
f. nov. fructu abundanter piloso. 
Type Specimen: Marne: in sand growing over bushes, Pemaquid 
Beach, Bristol, September 9, 1898 (E. B. Chamberlain, G. E. Dins- 
more, no. 832, in Herb. Gray). 
The genus Schmaltzia Desv. has been recently taken up for some of 
the species of Rhus. The principal reason for doing this seems to have 
been the pubescent nature of the fruit. Small in his Flora of the 
Southeastern United States separates the genus Rhus from Schmaltzia 
in the key to the family Spondiaceae as follows: 
Drupe with a glabrous outer coat: stone ribbed. 3. Rhus. 
Drupe with a pubescent fruit: stone smooth. 4. Schmaltzia. 
However, in the Bristol plant under discussion, as well as in the 
Florida plant referred to and in two specimens from Georgia collected 
by Mr. Harley Harris Bartlett, we have undoubted congeners of 
Rhus Toxicodendron with pubescent fruit, a fact decidedly opposed 
to the maintenance of Schmaltzia as a distinct genus on the same 
ground. 
A modification of the poison ivy not rarely met with is a teratological 
form in which the flowers are replaced by tiny leaves, each trifoliolate 
in the usual manner. Since this plant is teratological and since it can 
obviously not reproduce itself sexually, it does not properly belong in 
the sequence of what one may term evolutionary classification; yet it 
seems worthy of notice and record. ‘This abnormal development is 
common amongst the Krummholz of Pinus sylvestris L. at Wood's 
Hole, Massachusetts. Inthe herbarium of the New England Botanical 
Club there is a specimen of the same form from Furnace Brook, Blue 
Hills, August 15, 1894 (W. H. Manning).
