MR. D. OLIVER ON ATTRANTIACE^. 15 



Murray A (including Berg era). 



To this genus has been ascribed a 2-celled ovary, with gemi- 

 nate, superimposed ovules in each cell ; to Bergera also a 2-celled 

 ovary, but solitary ovules. Messrs. Dalzell* and Thwaitesf ob- 

 serve, however, as I have also found, that Bergera occurs some- 

 times with geminate ovules. Mr. Dalzell states that when there 

 are two ovules in a cell, he finds them to be collateral. In the 

 specimens which I have examined, I find them either obliquely 

 superimposed, or very nearly quite collateral ; thus indicating an 

 approach to Murraga. Mr. Thwaites sends from Ceylon a Mur- 

 ray a, under the MS. name of M. Glenicii, precisely resembling M. 

 exotica, but with 5 or 4 loculaments to the ovary. And, again, 

 specimens of an Aurantiacea collected in the Philippines, referred 

 by Turczaninow to Glgcosmis, though with very decidedly the 

 facies of a Murraga, present 5-locular ovaries with the ovules 

 sometimes solitary, sometimes geminate, and in the latter case 

 either obliquely superimposed or quite collateral. As in all other 

 respects, apart from the ovarium and its contents, Murraga and 

 Bergera closely approach each other, I" have, in consideration of 

 the facts above noted, concluded to follow SprengelJ in com- 

 bining the two genera. They agree well in inflorescence, in the 

 linear -subulate filaments bearing small rotundate anthers, the 

 rather long style— at first continuous with the ovary, at length 

 caducous at a little above its base— and probably also in the disk 

 bearing the scars of the fallen whorls, which after flowering grows 

 out in one or two species so as to fill the calyx. In Bergera the 

 leaves are usually slightly pubescent, at least on the rachis and 

 midribs, and they are less coriaceous than in Murraga ; the testa 

 of the seeds, also, is glabrous in the former, but these of them- 

 selves are comparatively trivial exceptions. In the biovulate M. 

 exotica, I find the ovules to originate at the same, or very nearly 

 the same, level on the placenta ; one of these becomes eventually 

 pendulous and shortly funiculate, while the other, and superior, is 

 more or less peltate.

 upon a species met with in Bombay. The same plant (P. indica) 

 has been also sent from Ceylon by Colonel Walker, Dr. Gardner,
