roundish, 1-seeded, the size of a large pea. Gemmula viviparous, or com- 
mencing to vegetate as soon as mature, (cotyledons none), primary vagi- 
nate leaves 2 or 3, Jinear;.and subulate, the 4th leaf usually exhibiting a 
small lamina. Primary radicle conspicuous, conic. Scmcrhize* roun ish, 
large, dark green, umbilically depressed at the summit, having a sma"! 
concealed internal cavity, and a lateral shallow groove, for the reception 
of the gemmule, which is appressed to it, and curved over the greater 
pari of the somothize.” 
A native of North America, from Canada to Florida, grow- 
ing in rivulets, and low and stagnant waters (PursH), and, as 
Mr Nurraut believes, almost exclusively within the limits 
of tide-water. It bears the winter well with us, and is readily 
cultivated in ponds, along with other aquatic plants. It was 
introduced to this country by Dr Jonn ForHERGitt, in the 
year 1775, but. hitherto no delineation of it has appeared in 
any British botanical publication. That in the Ameenitates 
“Aeademice, if really mtended for this plant, conveys a most 
incorrect idea of it; for the scape is represented as deeply fur- 
rowed, furnished with a large bractea; the leaf has one central 
rib, and several lateral. parallel nerves, resembling the foliage of 
most Dicotyledonous Plants. 3
