Specimens examined from New Brunswick (J. Fowler, Bass river, 
Kent Co., July 28, 1870); Maine (Swan, Kennebec, 1859) ; Massachusetts 
(W. Boott, Woburn Pond and Mystic River, 1863, and North Cambridge,

LOPHOTOCARPUS SPATULATUS N. sp. 
Low aquatic, 3-7 cm. high, the phyllodia bladeless, or 
sometimes spatulately broadened at the tip, ascending, with 
the edges vertical through a twist in the base, 3-6 mm. 
wide, obtuse or rounded at the apex. Scape simple, usu- 
ally shorter than the phyllodia, 3-4 cm. long, one or two- 
flowered, thickened and reflexed after flowering. Bracts 
minute, 3 mm. long, scarious, broadly ovate, obtuse. 
Stamens 6-9, the filaments flattened, incurved, broadest at 
the base, 1.5—-2 mm. long, smooth, the anthers 1 mm. long, 
oblong. Sepals oblong-orbicular, thin, 3mm. long, nerve- 
less, thin-scarious on the margins, and papery in fruit. 
Petals ovate orbicular, obtuse, 6 mm. long. Achenia 1.5 
mm., obliquely obovate, obtuse, narrowly winged on the 
back to about the level of the beak, and sometimes with a 
transverse lateral ridge near the top, with a slender, oblique 
or horizontal beak inserted below the apex. The phyllodia 
are frequently nodose towards the base. — Plate 57. 
Collected by Alvah A. Eaton, Newburyport, Massachu- 
setts, on sandy beaches along the Merrimac River, above 
salt water but within the influence of thetides. Mr. Eaton 
has had this plant under observation for five years, and 
says, concerning it: ‘* The plant never gets larger, never 
has but one whorl of flowers, usually one or two, seldom 
three, on a scape. The fruit is buried inthe mud in which 
the plant grows by the recurving pedicels and scape. Cul- 
tivation does not change the plant in the least, as I have 
had it in my water garden during the summer and in the 
greenhouse now.”’ 
Type specimens in Herb. Mo. Bot. Garden, and in the 
National Herbarium. This plant seems to be well distin-
