incomplete or erroneous. Thus, if we compare our specimens with 

 the analysis of A. concolor, as represented by Poeppig (Nov. Gen. 

 t. 190), his 3 petals do not exist, the monadelphy is only a slight 

 adherence of the stamens at the base itself, and his embryo 

 (figured erroneously on the inner side of the endosperm, and 

 bearing foliaceous cotyledons) is merely a thickening of the 

 endocarpic dissepiment, the real embryo having been overlooked 

 in the interior channel of the endosperm. Miers, on the other 

 hand, of whom I have compared such materials as exist in Sir 

 "W. Hooker's and Bentham's herbaria, was mistaken, in conse- 

 quence of the incompleteness of the specimens, in his character of 

 Anelasma, which he describes as apetalous, and presenting an ex- 

 albuminose embryo with large thick cotyledons, — though Poeppig, 

 with respect to A. concolor, had given a nearly correct idea of the 

 large ruminated albumen, formed exactly in the same way as in A. 

 rufescens, and though Cocculus domingensis, the second species of 

 his genus Anelasma, exhibits 6 petals in its male flower. A seed 

 of the latter, which had been examined by Miers, I found not 

 impregnated, and in consequence the drupe filled only partially 

 by a dead tissue, taken possibly for an exalbuminose embryo. 



Abuta rufescens, Aubl., is characterized by ovate, pointed, five- 

 nerved leaves, velvety on their under side, and by the inflorescence 

 and the ovaries downy. Its apparent synonyms are Batschia 

 racemosa and conferta, Thunb. (Nov. Act. Tips. v. t. 2. f. 1, 2, — 

 a tolerable representation of the genus), both forms from New 

 G-ranada, — the range of the species comprising the whole of equa- 

 torial America from that country to the Amazons and Guiana. 



A. concolor, Poepp., approaching in habit to Cocculus domin- 

 gensis, is distinguished by elliptical polished leaves, the primary 

 veins of which are separate at the base itself, and the tertiary 

 veinlets not prominent. Its synonyms are, Anelasma Sprucea/num, 

 Miers!, A. guianense, Miers!, and probably Cocculus Icevigatus, 

 Mart. Its geographical range comprises a still larger area, viz. 

 equatorial Brazil !, Goyaz (Gardn. no. 3567 !), Cayenne (Martin).
