1919] Woodward,— Some Connecticut Plants 115 
floating on the water. These have oblong anthers, which are 0.8-1.0 
mm.long. In the pistillate flower the three stigmas are linear, 2-cleft, 
and exceeding the perianth, which is, at least in dried specimens, 
purplish or purple-flecked. The fruit of Elodea is ordinarily described 
as oblong, but in this plant the fruit is globose, although the persistent 
base of the style may give an oblong appearance to partly grown 
fruit. We have in Connecticut Elodeas with oblong fruit, and others 
with globose fruit, a fact which indicates that specific characters 
may yet be found in the fruit. In general, this Old Lyme plant 
agrees well with Rydberg’s description of Philotria angustifolia 
(Muhl.) Britton,' and is apparently this species, or close to it, although 
in the literature at command, the writer has been unable to find a 
printed record of Elodea in marine waters, and our local collectors state 
that they have not met with the genus in such waters. It was growing 
at, or below, the edge of low water. The herbarium sheets, showing 
both kinds of flowers, and mature fruit, are more satisfactory than 
sheets of Elodea usually are. 
LoPHOTOCARPUS SPONGIOSUS, reported in the Connecticut Catalogue 
by Dr. C. B. Graves as rare at-Old Lyme, was noticed the past summer, 
in the same town, at one station, where it was quite abundant, and 
many plants were seen with scapes reaching the unusual height of 
20 cm., although the majority were tiny affairs, 4 or 5 em. high. 
PANICUM VIRGATUM CUBENSE. The writer has in his herbarium a 
sheet of this variety collected at Norwich, August 11, 1900, on a 
gravel bank along the Shetucket river a few miles above its entrance 
into the Thames. The spikelets are 2.8-3 mm. long and match 
perfectly material verified by Mrs. Agnes Chase, but the panicles are 
less strict than is usual in this form of P. virgatum. The same variety 
has been collected by Dr. C. B. Graves at Groton, a town on the east 
bank of the Thames at its mouth, and the writer has found it at 
Westerly, Rhode Island, a few miles east of Groton, where it is abun- 
dant at several stations in brackish sand.? This appears to be another 
instance, of which there are several, of southern or coastal species 
following up the Thames, a tidal stream, and its tributaries. Thus, 
Paspalum psammophilum is known from several stations along the 
Shetucket, P. circulare occurs on the Yantic, another tributary of
