subspiraliter longitudinalibus, ovula plurima creberrime imbricata et subdivaricatim suspensa 
gerentibus. Stylus simplex, pilosus. Stigma trifidum, laciniis longiusculis, acutis, erecto-conni- 
ventibus, margine fimbriato-laceratis. Capsula membranaceo-testacea, elongata, cylindrica, imo 
paulo attenuata, calycis laciniis reflexis coronata, apice pulvine styloque apiculata, hinc demum 
operculatim 3-fissa, nervis plurimis eleganter striata, 1-locularis, 3-valvis, valvis circa coronam caly- 
cinam etiamque ad basin arcte cohærentibus et lateraliter apud suturas modo torsili hiantibus. 
Semina numerosissima, parva, circa margines valvarum ad placentas 3 toruloso-flagelliformes demum 
solutas creberrime suspensa; integumentum externum elongatum, crumenatum, laxissimum, fortiter 
reticulato-cancellatum ; tunica intermedia multo minor, soluta, et in centro natans, crassa, foveolato- 
reticulata, obscura, extremitatibus laxis in pellicula tenuissima evanescentibus ; integumentum in- 
ternum simplex, tenuissimum, reticulatum, albumen arcte vestiens; albumen ovale, carnosum; em- 
bryo inclusus, paulo brevior, cylindrico-oblongus, radicula supera, crassiuscula, cotyledonibus ejus- 
dem diametro paulo brevioribus.—Herbz Brasilienses scandentes, scabrido-pilose ; folia opposita, ex- 
stipulata, suborbicularia, inciso-lobata, cordata, imo 5-nervia, longe petiolata ; panicule avillares et 
terminales, basi nude, tandem dichotome ; flores sepius solitarii, pedicellati, in sinibus dichotomiarum 
orti, imo bracteis Joliosis donati ; petala majora, viridi-aurantiaca, minora rubescentia. 
^ GRIPIDEA SCABRA, nob.; herbacea, ramis succulento-fistulosis, striatis, ruguloso- 
verruculosis, petiolisque retrorsim rigide pilosis ; foliis latis, inæqualiter 5-lobis, imo 
profunde auriculato-cordatis, lobis acutis, subsinuatis, eroso-denticulatis, e basi 
5-nerviis, utrinque scabridis et vix adpresse pilosis, supra viridibus, subnitentibus, 
subtus pallidioribus, opacis, petiolo limbo æquilongo, subito deflexo; paniculis op- 
| positis, patentibus, pedunculo nudo, folium æquante, apice dichotome ramoso, ramis 
| Imo bracteatis, bracteis gradatim minoribus, foliaceis, subsessilibus, denticulatis, 
floribus in dichotomiis solitariis, pedicellatis. In Brasilia meridionali.—v. s. in herb.

There is little to add to the above description, and the accompanying drawing of the 
colour a] € larger petals are greenish on the summit and back, and of a bright orange 
Mong the broad compressed margins; the smaller petals, considered by many as 
Qu “ processes, are of a pale reddish colour; all the filaments are white, the fertile 
Wu nearly the length of the petals, and very slender; the anthers are very small, 
i of a pale yellow colour, and dorsally affixed upon a fleshy connective.
