Of these T. burmannia is closely allied to P. obovata Bennett in 

 Horsf. PI. Jav. Ear. p. 127. t. 27. 



The fourth species was met with sparingly in fruit on Mount 

 Ophir ; in the form of its leaves it approaches to T. obovata, but the 

 fruit is rounder. The peduncles appear much less branched than in 

 any of the other extra- Australian species, but the degree of adhesion 

 between the calyx and pericarpium is the same. It was observed 

 with Bseckea frutescens, three species of Leptospermum, and one 

 of Leucopogon.* 



I know so little of the Australian species of this genus and family 

 that I am unable to state what value should be attached to the pla- 

 centation in these four extra- Australian species, to the abortion and 

 deformity of most of the seeds, the wing of the fertile one, and the 

 embryo. The habit and especially geographic distribution would 

 seem to point to some degree of separation. It is to be remember- 

 ed, however, that Mr. Bennett in the* PI. Jav. Ear., a work of the 

 highest authority, does not remark on any structural peculiarity 

 presented by Tristania obovata, his specimens of which, excepting 

 the absence of ripe seeds, appear to have been complete. 



Eubiace^;. — I notice Epithinia mayana, to confirm Messrs. Wight 

 and Arnott's statement, that it has stipulse. The opposite state- 

 ment, in the Malayan Miscellanies, I have ascertained was correct- 

 ed! by Dr. Jack himself in a copy found thrown aside among some 



* The Mount Ophir species of this genus, which is not uncommon at Paddam 

 Bhattoo, differs from that found on the littoral tracts of Malacca in the narrow 

 leaves crowded on short branches, the corolla scarcely partite to the middle, the 

 large hypogynous scales which nearly enclose the ovarium, and the smooth filiform 

 style. For this the name L. ophirensis may be proposed. 



Indeed it was improbable that an exclusively littoral plant should make its 

 appearance suddenly on an isolated Mountain at an elevation of 2000 feet any 

 where : much more so on Mount Ophir, the productions of which from Paddam 

 Bhattoo upwards are very dissimilar from general Malacca vegetation, approaching 

 much more to that characteristic of Polynesia and Australia ? 



f Instead of" Stipules none," it is, " stipules short,_interpetiolar."
