427, Conysa apurensis, Humb. et Kunth.—DC. Prod. v. 5. p. 380. var. hispidior, foliis 
majoribus, inferioribus longe petiolatis obovatis grosse dentatis, cetera omnia uti a Kunthio 
descripta.—Central America. 
428. Baccuanis rhexioides, Humb. et Kunth.—DC. Prod. v. 5. p. 399.—Answers well to De 
Candolle’s character, and to Kunth’s description, and agrees with specimens from other parts of 
South America, but very unlike any Rhexia I am acquainted with.—Columbia. 
429. Baccnanis cinerea, DC. Prod. v. 5. p. 400.—The specimens (both male and female) are 
more rigid, and the heads of flowers more numerous and crowded than is usual in Brasilian ones, 
but I cannot perceive any specific difference.—Guayaquil. 
430. Baccuaris spartea, sp. n., suffruticosa? glabra, ramis virgatis striatis, foliis subsessilibus

apices ramulorum panicule pyramidatz foliose sessilibus, involucri campanulati squamis margine 
scarioso-fimbriatis, exterioribus ovatis obtusis, interioribus oblongis acutiusculis, receptaculo 
paleato.— Huamantango. 
Specimina que adsunt omnia feeminea. Ramuli (vel caules ?) parum ramosi, sesquipedales, paucifoliati, iis 
Geniste tinctorie subsimiles, superne subviscosi. Folia sparsa, majora pollicem longa, 13-2 lin. lata, apice 
_ rotundata, mucronulo minuto, basi angustata et nonnulla subpetiolata, subcoriacea, utrinque viridia, costa media

subconformia at multo minora, Panicula pyramidata vel subcorymbosa, vix semipedalis, polycephala. Capitula 
ad apices ramulorum 2-6, congesta, vix 24 lin. longa. Involucri squame pluriseriatim imbricate, exteriores 
breves latee appressee, interiores gradatim longiores, seriei intime apice patentes, omnes margine scariosee, medio 
dorso virides. Receptaculum planum. Pale deciduz, anguste, scariose, pappo paullo breviores. Flores 
eenages (ultra 30). Corolle filiformes, truncate, pappo breviores. Styli rami angusti, acuti, planiusculi. 
Ovarium glabrum. Acheenia non vidi. 
| The Baccharides with paleate receptacles have been generally distinguished, 
by C. H. Schultz, under the name of Achyrobaccharis, but, as far as hitherto known, 
this character appears much too indefinite, and too little accompanied by any 
other difference to warrant the separation.
