114 REPORT ON THE PLANTS 
sepe decidua (v. deficientia ?). Petala alba, quam in 4. tenuiflora 
minora et latiora, vix 6 lin. longa, distincte acuminata et in unguem 
basi contracta, medio late rhomboidea et concava. Stamina nume- 
rosissima. 
The Menispermacee have been examined by Mr. Miers, who has re- 
cognized three new species of Cissampelos, of which one only, C. Amazo- 
nica, Miers, has been distributed into most sets under the name of 
“ Cissampelos, sp. n., affinis C. ovalifolize," the two others having been 
only in single, or in very few, specimens. Another plant inserted in a 
very few sets under the name of ** Cocculus affinis C. lævigatæ, Mart.,” 
is the Anelasma Spruceanum, Miers. Besides these, a very curious plant 
has been rather more generally distributed as “ Genus novum affine 
Menispermaceis :” it is the Aptandra Spruceanum, Miers, whose very 
doubtful affinities will be more fully discussed by Mr. Miers on a future 
occasion. In the meantime, that gentleman has kindly communicated 
to me the following characters for the above-mentioned new species :— 
1. Cissampelos assimilis, Miers, n. sp.; ramulis striatis tomentosis, 
foliis orbieulato-ovatis undulato-sinuatis apice retusis opacis supra 
pubescentibus subtus cinereo-tomentosis (junioribus acutis utrinque 
fulvo-tomentosis) longiuscule petiolatis, petiolo erecto, limbo subre- 
fracto, racemis paniculatis ternis axillaribus petiolo subzequilongis 
tenerrimis, sepalis spathulatis extus pilosis, corolla 4-loba glabra, 
anthera 4-loba.—Prope Santarem. 
This closely approaches C. crenata, DC., but the leaves are more 
glabrous above; the under surface not so densely tomentose. Thé 
petiole is half the length of the blade (while in C. crenata the leaves 
are almost sessile), the panicles are three (not two) in each axil, the 
peduncle and pedicel are far more slender, and the anther is 4- (not 6-) 
lobed. 
2. Cissampelos Amazonica, Miers, n. sp. ; foliis ovalibus subacutis cre- 
nato-sinuatis mucronatis coriaceis supra glabris nitidis reticulatis 
subtus fusco-tomentosis 5—7-nerviis sublonge petiolatis, racemis fæm. 
(ramulis novellis) binis folio brevioribus bracteatis, bracteis conspi- 
cuis orbieularibus mucronatis utrinque tomentosis, floribus minutis 
pedicellatis in axillas 6—7-fasciculatis, fructu piloso.— Prope Santarem. 
This plant may be confounded with C. ovalifolia, DC., which it 
greatly resembles in the shape and texture of its leaves, but their upper 
surface is far more shining ; the petiole is about one-fourth the length
