nuts containing imperfect seeds. Loureiro's typical specimen 

 from Cocliin-China exists in the herbarium of the British Mu- 

 seum ; this I have examined, together with three other species 

 from Malacca, which I have found in the herbaria of Sir William 

 Hooker and Dr. Lemann. 



10. Parahana, a genus of which I possess complete details; 

 the typical species is identical with the Cissampelos oleracea, 

 Wall. Cat. no. 4984 : the other species are : 2. P. sagittata 

 {Cissampelos sagittata, Wall. Cat. 4983) ; 3. P. heterophylla, from 

 Assam, in the collections of the late Mr. Griffiths [p.. 355) ; 4. 

 P.ferruginea (idem, no. 74). 



11. Anomospermum. This genus comprises three species 

 from Brazil and Guiana : the typical one was found by me in 

 the Organ Mountains, when I made a very complete analysis 

 from living specimens. 1. A. nitidum. 2. A. Schomburgkii 

 (Schomburgk's Guiana Collection, no. 833). 3. A. Hostmanni 

 (Hostmann^s Surinam Collection, no. ). 



12. Tiliacora, Coleb., an Indian genus consisting of several 

 species, the type of which is T. acuminata {T. racemosa, Coleb. ; 

 Cocculus acuminatus, DC, Deless. Icon. i. tab. 95, Wall. Cat. 

 no. 4958). I have obtained complete details of the structure of 

 the male flowers and of the seed, but the female flowers are yet 

 wanting. One species from Ceylon presents a circumstance of 

 rare occurrence in this order, perfectly hermaphrodite flowers ; 

 but whether this be a constant character, or only a casual occur- 

 rence, can only be ascertained by future observations with com- 

 petent specimens. Bisexual flowers are also met with in other 

 genera, although very rarely. 



13. Abuta. I have restored this genus of Aublet upon a 

 distinct group of plants from Brazil and Guiana. Nine species 

 may be referred here, including among them the Batschia ra- 

 cemosa and the B. conferta of Thunberg (the genus Trichoa of 

 Persoon), which I have had no opportunity of examining. 1 met 

 with a single species in the neighbourhood of Bio de Janeiro, 

 which offered male flowers only, but Martin's specimens from 

 Cayenne have afforded ample details of the structure of the 

 female flowers. Cunningham's collection exhibits specimens in 

 fruit, but unfortunately not sufficiently matured to enable me 

 to determine the form of the embryo. In the structure of the 

 nut, and the form of the nucleus, it approaches Tiliacora, and 

 the nucleus appears lamellated when cut transversely, as if it 

 were ruminated albumen, but this point could not be determined 

 with any degree of certainty from the imperfect state of the 

 specimens in question ; its position among the Tiliacorea cannot 

 therefore be yet affirmed with confidence. The typical species 

 is \h.e-Abuta rufescens, Aubl. (PI. Guy. tab. 250), with which the
