384 BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 
*Vicra Cracca L. : 
Scattered in tangled masses through a field east of Island Home, 
June 28, 1912; abundant and in full flower in a sandy field at Surf- 
side, July 9, 1912. 
*ACER NEGUNDO L. 
An estray from cultivation. Collected by Mrs. Flynn in full 
flower May 5, 1906. 
*ABUTILON THEOPHRASTI Medic. 
Rubbish dump on Prospect Hill, collected by Miss Gardner in 
full flower September 9, 1914. 
*VIOLA TRICOLOR L. 
Scattered sparingly through the grass of a lawn on North 
Water Street, in full flower, June 20, 1910. 
*LYTHRUM SALICARIA L. 
In August, 1916, Miss Gardner sent me fresh specimens of the 
typical form of this plant from a field near No-bottom Pond, .and 
also a specimen of var. tomentosum (Mill.) DC. from a field near 
Lily Pond, both collected by Mrs. G. A. Spear. The typical 
plant had not previously been found on Nantucket. 
So different of aspect are these two plants, and so well defined 
are comparative differences between them that the eye hesitates to 
accept them as being of no greater diversity than mere variants of 
a single species. The Nantucket var. tomentosum is not exceptional, 
for when I have met with it elsewhere its differences from true 
L. Salicaria were equally pronounced. It may be significant of 
different soil preferences of the two plants that var. tomentosum 
appears to be the only one that is found along the sandy south 
shore of Long Island where, though scarce, it is widely scattered, 
while the locally abundant plant of heavy wet soils along the 
Hudson, and inland in boggy places among the hills, is the typical 
form. 
*OENOTHERA RUBESCENS Bartlett. 
Little is known of this Oenothera recently described by Dr. H. H. 
Bartlett from plants raised from Nantucket seeds (Cybele Colum- 
biana 1: 50. 1914). It is probable that the living plant also 
has been collected on Nantucket. Specimens, not yet mature,
