fasciculatisj disci laciiiiis apice incurvo-biiidis filamento in incisura 

 inserto, ovario glabro, stylo hirsute. — Wall. Cat. n. 7189. — Vareca 

 heteroclita, Roxh. Fl. Ind. i. p. 648 ; (^erf. Wall. J ii. p. 246. 



Hab. — In Hindustania ; Martin. 



Folia (in exemplo meo) 1-1 5; poll, longa, basi cuneata, subsessilia. 

 Antherarum appendix lata, loculos parum superans, truncata. 



Roxburgh says of the base of the filaments, that " each side is 

 enlarged with one or more adjoined hornlets, which are bearded at 

 the base." These hornlets are what I consider the lobes of the seg- 

 ments of the disk, and in the only flower, in a sufliciently advanced 

 state, that I found on my specimen, they were quite glabrous, but 

 the base of the anthers, or very apex of the filaments was woolly. 

 I am not quite satisfied whether the disk is, as I have called it, only 

 5-partite, or whether it be not composed of 5 scales distinct at the 

 base ; they appeared slightly connected there, but separated with 

 great facility. 



In all the species Avhich I have examined, there are only three 

 ovules in each ovarium, one to each parietal placenta. 1 hesitate^ 

 therefore, in placing in the same genus Vareca moluccana, Roxb., of 

 which the ovary is said to contain " many ovules attached to two 

 or three parietal receptacles ;" but that plant, as described, differs 

 also from Penlaloba in several other important particulars, as in the 

 Avant of stipules, villous peduncles, young shoots clothed with fer- 

 ruginous pubescence, calyx 5-toothed, villous and caducous, and 

 apparently no disk. Can it be a species of Prosthesia of Blume ? 

 a genus as already pointed out by Meisner (Plant, vase. gen. Comm. 

 p. 18,) very closely allied to Pentaloha, but differing by the nume- 

 rous ovules. If so, Roxburgh's description must be considered as 

 erroneous in several particulars. I feel, however, more disposed to 

 refer it to Pittosporum, to which genus liea umbellata Roxb., and 

 Celastrus verticillatus, Roxb. appear also to belong.
