Materials for a Flora of the Malayan Peninsula. 



jplants whicli form this section are to be included uuder Santiria ; for 

 the flowers of TrigonucJdamys are really more like those of Ganariurn, 

 than of Santiria. The separation of Ganariurn from Santiria by 

 characters taken from the drupe, in my opinion, fails. The drupe of 

 Ganariurn is defined as 1 inch or more in length, ovoid or oblong-ovoid, 

 never gibbous, boldly trigonous, its sides equal and its endocarp hard 

 thick and strong, 3-to 1-celled, and the scar of the style apical ; while 

 that of Santiria is usually less than 1 in. long, shortly and obliquely 

 ovoid or sub-globose, often gibbous, the endocaip being thin, coriaceous, 

 sub-ligneous, never bony, 1-celled, and the scar of the style lateral and 

 often approximated to the base. Unfortunately several species from. 

 Perak (which in other respects have the fades of Santiria) have the style- 

 scar quite terminal; while, on the other hand, some species with many 

 of the characters of Canariwm have drupes of which the endocarp 

 is not more bony than that of several species of Santiria. The 

 characters drawn from the flower, which I have given above, do not 

 appear to me to have hitherto had sufficient value attached to them. 



By transferring Santiria Planclioni, Benn. to Ganariurn ; by keeping 

 up Trigonochlamys as a genus characterised by its very large calyx, and 

 globose drupe ; and by restricting Santiria to the plants which form the 

 section Eu-santiria of Engler, I venture to think that the study of all 

 the plants concerned will be simplified.
