SomE RuopeE Istanp GrassEs.— The following grasses appear to 
be new to the recorded flora of Rhode Island. 
Puccinellia paupercula alaskana.' This plant occurs at Westerly, 
where it is the prominent grass on a large, sand-coated marsh, growing 
with Spergularia leiosperma, S. salina, Suaeda linearis and other 
saline species. 
Panicum virgatum cubense. This variety occurs associated with the 
species at Westerly. Mrs. Agnes Chase, who has kindly examined 
specimens from Westerly, states that they are exactly like Graves, 
244, Groton, Connecticut, August 16, 1901.2. Both have the narrow 
panicle and small spikelets of var. cubense, but the glumes and sterile 
lemma are more pointed than in characteristic var. cubense from New 
Jersey southward. Mrs. Chase adds that they are, however, nearer 
to the variety than they are to the species. 
Panicum oricola. This species is abundant in Westerly at several 
stations along the shore of the Sound. Specimens have been verified 
by Mrs. Chase.— R. W. Woopwarp, New Haven, Connecticut. 
A New VARIETY oF TRIOSTEUM AURANTIACUM.— In central New 
York there are two well marked forms of T'riostewm aurantiacum 
which do not seem to intergrade to any appreciable extent. Both 
are about equally common. The two types differ in the lower surface 
of the leaves as follows: typical form of the species, leaves densely 
velvety-canescent beneath. 
kaw glaucescens, var. nov., foliis subtus glabris aut ad venas sparse 
ilosis. 
r Leaves glabrous beneath or sparsely pilose along the veins.— Com- 
mon in central New York. The only other specimen seen is from 
“South Mountain above Penryn, Lebanon County, Pennsylvania, 
May 1891” Heller & Halbach. Type (in herb. N. Y. State Col. of 
Agric. Ithaca): rich bottomland, Paine’s Creek, Ledyard, Cayuga 
County, New York, June 20, 1916, K. M. Wiegand, no. 7196. 
In 1836, Rafinesque (New Flora N. A. Pt. 2, p. 35-37) published 
six new names in Triosteum but I cannot definitely ascribe any of these 
either to 7. aurantiacum or the present variety, though probably 
Rafinesque had at least one of these plants in hand.— K. M. WIEGAND, 
Cornell University.

Vol. 20, no. 233, including pages 81 to 100, was issued 1 May, 1918.
