much ruminated albumen, as characterized by Grisebach in the 

 abovementioned note. 



4. Coccultts, Linn., as now limited, with small petals, free 

 stamens, horseshoe seeds, and entire albumen. 



5. Hyfebb-ENa, Miers, with Cocculus flowers and horseshoe 

 seeds, but a thick, fleshy embryo without albumen. 



6. Botbtopsis, Miers, with the fruit and seed of Hyperbcena, 

 but a very different habit, an increase in the number of sepals, 

 and long inflected points to the anthers. 



7. Sciadot^enia, Miers, with the seeds of Hyperbcena, but the 

 carpels raised on long pedicels as in Tiliacora ; the male flowers as 

 yet unknown. 



Chondodendbon, Ruiz et Pav. 



Although the seeds in this American genus have only been seen 

 by Poeppig, and although his description is very imperfect and 

 his figure rude, there seems no reason to doubt that they are 

 similar to those of the Asiatic Tinospora, from which there is little 

 to distinguish it besides the monadelphous stamens. Miers men- 

 tions 8 species, but, judging from our specimens, I can find no cha- 

 racter to separate the C. convolvulaceim, Poepp., C. hederafolium, 

 Miers, and C. scabrum, Miers, from the original C. tomentosum, 

 E. et P. The form of the leaves will vary on the same specimen 

 from quite entire and cordate with a deep narrow sinus, to broadly 

 and openly cordate and more or less hastately 3-lobed. They are 

 always more or less pubescent underneath, sometimes densely and 

 softly so, and rough on the upper side with a very minute pubes- 

 cence. The species is widely spread in Brazil, Guiana, and the 

 eastern side of the Peruvian Andes. It is also Spruce's n. 3567, 

 from the banks of the Guainia or Upper Eio Negro in Venezuela, 

 where it establishes itself in places once cultivated. The C. to- 

 moides, Miers {Cocculus tamoides, DC. Syst. Veg. v. i. p. 521), has 

 the same diversity in the form of the leaves ; but they appear to 

 be perfectly glabrous. I have only seen it from Cayenne and 

 British Guiana. 



Anomospebmum, Miers. 



Miers proposes three species of this genus which is very pecu- 

 liar in habit and character; but on comparing a considerable 

 number of specimens, I am unable to separate them into distinct 

 varieties. The A. Hostmanni, Miers, has indeed rather smaller
