44 Mr. J. Miers on the Menispermacese. 



36. Chondodendron, K. and P. I have restored this genus of 

 the Flora Peruviana, upon a very distinct group of plants, all of 

 South American origin, and of which the type is the Chondo- 

 dendron tomentosum, R. and P. [Cocailus Chondodendron, DC). 

 Another species is figured by Poppig (Nov. Gen. tab. 190), under 

 the name of Chondodendron convolvulaceum. I have seen only 

 the male and female flowers, but not the fruit : from his figure 

 of the seed, we might conclude it must belong to the Hetero- 

 cliniea, but as he describes the embryo to be perispherical, and 

 does not state whether or not it be albuminous, it remains un- 

 certain to which tribe this genus can be referred ; in habit, all 

 the species bear a remarkable resemblance to Tinospora. Coc- 

 culus tamoides, DC, is referrible here. I have determined eight 

 species altogether, among which are two plants collected by 

 Gardner in Piauhy, which I have named C. hederifolium (Gardn. 

 n. 2009) and C. scabrum (Gardn. n. 2473). 



37. Hrjperbcena is a genus comprising a group of South 

 American and Mexican plants, the type of which, H. nemoralis, 

 I found in the forests of the Corcovado, near Rio de Janeiro. 

 The characters of both the male and female flowers are deter- 

 mined, but the fruit is wanting to fix the tribe to which it 

 belongs. I have met with five species, viz. the above-mentioned ; 

 H. Moricandii from Ilheos (Moric. n. 2346) ; H. Hostmanni from 

 Sui'inam (Hostm. n. 1050) ; H. Mexicana from Mexico (Jun- 

 gensen, n. 91) ; H. Tweedii from Rio Grande do Sul (Tweedie). 

 They bear much the habit of some species of Anelasma. 



38. Tinomiscium is constituted for thi-ee plants of peculiar 

 habit: the Cocculus peiiolaris, Wall. (Cat. n. 4964), Cocculics 

 coriaceus, Hook., both from Penang; and a species from Java 

 (Zollinger, n. 745). All these species present only male flowers, 

 so that it is yet uncertain to which tribe they can be referred ; 

 but from their peculiar habit and the larger size and structure 

 of their flowers, they more I'esemble the Heterocliniece. 



39. Prjcnarrhena is proposed for a plant from Sylhet, of a very 

 distinct appearance and habit, approching Anamirta in having 

 more than the usual number of stamens, aggregated in a central 

 globular mass. This plant is the Cocculus planifoliiis, Wall. 

 Cat. no. 4961) : it has only male flowers, so that it cannot yet 

 be referred with certainty to any particular tribe. 



40. Antifaxis is founded upon a plant from Malacca, collected 

 by the late Mr. Griffiths; it bears much analogy in habit to 

 Pycnarrhena, but is very different in the structure of its flower; 

 its floral envelopes are decussately arranged in opposite pairs, 

 there being only two petals and four stamens ; it has only male 

 flowers, hence its true position cannot yet be determined. 



The above brief remarks will afford some general notion of the
