7. TiNOMlSCIUM. 



When I proposed this genus in 1851, it was placed by me 

 among the genera of doubtful position, because its male flowers 

 alone were known ; but I suggested the probability of its belong- 

 ing to the Heterocliniea, on account of its habit. The authors 

 of the 'Flora Indica ' (p. 205) adopted a similar view, and, though 

 retaining it among the " genera dubise sedis,'' remarked that a 

 plant in fruit from Assam, of Griffiths's collection, described by 

 them (in p. 179), probably belonged to the genus. This I had 

 long before ascertained from a specimen in fruit shown to me 

 by the late Dr. Lemann, where the seeds showed clearly that 

 the genus belongs to the Heterocliniea, as I had supposed. The 

 drupe is more than an inch in length, with a nearly apical style ; 

 its thin rugose putamen has a broad, shallow, longitudinal 

 groove on the flattened ventral face ; and from this (the condyle) 

 the seed is suspended, or rather is attached to it within the cell : 

 from the immaturity of the nucleus, the precise form of the 

 embryo could not be ascertained ; but its thin foliaceous coty- 

 ledons were evident in the half-grown albumen, and in these 

 respects it nearly accords with the fruit of Fibraurea. The species 

 are all climbers; and the inflorescence consists of elongated slender 

 simple racemes, either single or fasciculated, in the axils of the 

 leaves.
