'Rm isa stejnless, floating, elegapt plant. Roots-many, a foot and a half loiig, putting 

 feHTth simple fibres from their circumference. Other fiin-es come out at the base of the 

 leaves, v.hich.arci sul)-sc>ssile, wtvlge-shap.cd at the base, elliptic, radiate-veined, 

 glancous-vel'v?t_y on tlie upper surtiirc : thtj central leaves smaller than the outer ones ; 

 the inmo.st erect, convoluted, tomentose. The runners are produced from the root 

 under the leaves, they are long and terminated b\- other suialler plants. Floweis whit- 

 ish, inodorous, axillary, solitaiy, and erect, on a sbort pqduucle. The corolla shrivelsL, 

 up more or less,, and b.ui-sts as the germ increa>es. 



This plant is rare in Jamaica, 1 have not ob.scrved it r.hove once in that island : it, 

 ',vas in a pond between Mis. Janies's and lir. Thene's, in St. James's : but it is ver}' 

 common in Antigua, where the greatest part of their waters is collected !u-.d preserved 

 m ponds, h.M" the public r.:;e. It grows and vhrives very luxuriantly in tlio.se reservoirs, 

 and keeps the whalers ahyays fresh and cool ; vvhifiii would ba greatly subject to putre- 

 faction, and chjirged with a multitude of insects, had they continued e.vposed to the 

 heat of the sun. It :has ils inconveniences, however, and those not very triiiing ; for 

 the plant is, of its own nature, acrid; atid when the droughts set -in, and the waters 

 are reduced very low (which frequently happens in that island), they are over-heated, 

 and so impregnated with the particles of this vegeuible, that they frequently give bloodv 

 fluxes to such as are obliged to use them at tho.se seasons : but this inconvenience may 

 be, in some measure, remedied, b\- mixing flour, or some other sheathing substance^ 

 with it, if necessity obliges the use of it in such k. state.- Broicne, j). 330.
