Mr. J. Miers on the Menispermacese. 259; 



Trichoa spicata, Pers. ; — Tricho aconferta, DC. — Rio Mag- 

 (lalena et Isth. Darien (Seemann). 



13. acutifulia, nob. ; — Abuta concolor, Benth. in part. — 



Panure (Spruce, 2763). 



The Abuta amara of Aublet is a species of Aristolochia. 

 The Abuta candicans, Rich., seems to accord better with Chon- 

 dodendron. 



The Abuta tomentosa, Sag., is also probably a Chondodendron. 



17. Anelasma. 



^ When I proposed this genus, in 1851, for a Brazilian plant, 

 upon a knowledge of the male flower only, its proper position 

 was mistaken, in the absence of the female flower and seed. 

 The examination of a specimen, in fruit, from the West Indies, 

 closely allied to the Cocculus Domingensis, DC, figured in Deles- 

 sert's ' Icones,' led me to infer, from their general appearance, 

 that all these plants belonged to the same genus; but having 

 obtained very soon afterwards other and more complete speci- 

 mens, I discovered the true carpological structure of AnelasmOy 

 and found that the Cocculus Domingensis and its allied species 

 appertained to Hyperbana — a genus then placed by me in the 

 dubious section for want of a knowledge of its seminal organiza- 

 tion. Dr.Grisebach subsequently pointed out the error as regarded 

 Hyperbana, but this I had discovered and rectified long previously. 

 Some species of Anelasma and Hyperbana so much resemble 

 one another in the form and veinless texture of their leaves, as 

 well as in their inflorescence, that they might easily be con- 

 founded by a superficial observation ; but more careful examina- 

 tion and an inspection of their floral or carpological structure 

 will remove all doubt, as the differences in these respects are 

 now well established. The liability of falling into error in the 

 determination of such plants, by trusting to mere external cha- 

 racters, has misled so experienced a botanist as Mr. Bentham, 

 who, in his " Notes on Menispemuicea" (Joum. Proc. Linn. Soc. 

 V. Suppl. 49), not only refers all my species of Anelasma to Abuta, 

 but has made other misconceptions, which I have pointed out. 

 1 need not repeat what has already been said [ante, p. 255) 

 concerning the opinions of Dr. Grisebach, Mr. Bentham, and 

 Dr. Hooker in regard to the supposed identity of Anelasma with 

 Abuta, nor recapitulate my reasons for holding them to be dis- 

 tinct. In addition to the many opposite characters there men- 

 tioned, another notable difference is worthy of attention : my 

 own observations demonstrate that the species of Abuta proper 

 are very lofty climbers, as may be judged from specimens seen 

 in herbaria, while the remarks of others show that those of Ajie-
