’ Mr. J. Miers on the Menispermacee. 259 
Trichoa spicata, Pers. ;—Tricho aconferta, DC.—Rio Mag- 
dalena et Isth. Darien (Seemann). 
acutifolia, nob. ;—Abuta concolor, Benth. in part.— 
Panuré (Spruce, 2763). 
The Aduta 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 Anelasma, 
and found that the Cocculus Domingensis and its allied species 
appertained to Hyperbena—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 
Hyperbena, but this I had discovered and rectified long previously. 
Some species of Anelasma and Hyperbena 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 fallimg 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 Menispermacee” (Journ. 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. 
I 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: m 
own observations demonstrate that the species of Abuta proper 
are very lofty climbers, as may be judged from specimens seen 
in herbaria, while the aiuele of others show that those of Ane-
