Calyx-lobes 4 (-5), linear. Anthers 8 (-10), equal, lanceolate-linear: tail arcuate, equal- 

 ing its two ascending spurs. Ovary at length free, without terminal bristles, 3-locular. — A 

 suffrutescent branched herb, with thin foliage ; panicle terminal, loose; pedicels slender ; 

 petals pointed. 



96. N. aquatica, Naud. — Leaves ovate-lanceolate, taper-pointed, cordate at the base, ~ 

 serrulate, 3-5-nerved; panicle triehotomous : pedicels filiform. — Aubl. t. 169. Bonpl. 

 Rhex. t. 40. — Rhexia, Sio. Spenuera, Mart. Sp. hydrophila, Miq. Sp. Asphalti, Crueg. I : 



a form with curled leaves. — Branches tetragonal, usually somewhat hairy ; petals flesh-

28. SPENNERA, DC. ; Naud. (I. c. 14. p. 141. t. 5). 



Calyx-limb with 4 minute teeth. Anthers 8, equal, oblong or roundish, without append-

 filament. Ovary at length free, without terminal bristles, 2-locular. — Herbs with thinfoli- 

 <*g e > growing in swampy situations ; panicle slender, loose, terminal, constituted of dichoto- 

 mous cymules ; buds conical. 



97. Sp. pellucida, DC. Suffrutescent; stem four-winged ; leaves ovate or ovate- 

 lanceolate, ciliate and roughish chiefly on the upper side ; panicle forming an elongated 

 thyrse ; tail of anthers nearly as long as the cells. — Miq. Comment. Phytogr. 1. 10 : quite 

 agreeing with our plant, but the capsule is described as trilocular (perhaps by monstrosity). — 

 Sp. tetraptera, Miq. Sp. martinicensis, Naud. — The shape of the leaves is variable, as has 

 been remarked by Miquel : there occur forms where the base is cordate or tapering, and the 

 top blunt or acuminate. — Hab. Trinidad !, Lockh., Cr., in swampy grounds and along river- 

 Banks ; [Martinique, Guiana!]. 



98. Sp. Kappleriana, Naud. Hairy and glandular ; leaves elliptical, ovate, or ellip- 

 tical-lanceolate, petioled ; cymes dichotomous, terminal on the branches, spreading ; anthers 

 oblong-linear: tail very short. — Sp. viscida, Miq. Sp. laxa, Cr..' (an DC.?). — The 

 cymes are shorter and the leaves are narrower than in Kappler's plant : but Crueger re- 

 marks that the form of the leaves is variable, and that they are sometimes blunt and cor- • 

 date, while in our specimens they are tapering on both ends. — Hab. Trinidad !, Cr. ; 

 [Guiana !].
