fimbriato-lacerae. Involucra turbinata, in axillis foliorum superiorum solitaria, breviter 

 pedicellata, una cum pedunculo sub li lin. longa, glandulis ad os transverse oblongis 

 nigris. Capsula 3-cocca, parva, glaberrima, sub 1 lin. diam., flavida. 



Closely allied to the E.polygonifolia, L., though quite distinct in its upright 

 habit, sessile leaves, keeled cocci and shorter fimbriated stipules. 



72. E. AMPLExicAULis, HooJi. Jil. ; glaberrima, erecta, glaucescens, caule su- 

 pern^ ramoso folioso, foliis oppositis sessilibus horizoutaliter patentibus 

 rotundato-reniformibus basi profunde cordatis amplexicaulibus integerri-

Radix valida, lignosa, perennis ? Caulis sublignosus, pedalis, basi simplex, nudus, multi- 

 articulatus, intemodiis |^-uncialibus, cortice laxo fusco-purpureo glauco tectus, superne 

 fastigiatim dichotome ramosus. Rami foliosi, divaricati, albido-glaucescentes, apicibus 

 ramulorum curvatis. Folia plurima, horizoutaliter patentia, uniformia, gradatim sur- 

 siim minora, basi profunde cordata, (hinc rami spurie perfoliati apparent,) ad apices 

 mucronulata vel retusa, interdum imo emarginata, pallide flavo-virescentia, marginibus 

 rubris valde coriaceis, inferiora 5 lin. longa, sub 4 lata. Involucra parva in axillis folio-

 zontalibus, aequilongis, stramineis, basi nigris. Capsula parva, sub 1 lin. longa ; coccis 

 subcompressis, dorso obtuse carinatis. 



Allied in habit and appearance to a species from the Bahama islands, but 

 very distinct from any I am acquainted with.
