this genus with Opilia, of Opiha with Champereia,* and of 

 the latter with Exocarpus and Leptomeria, be kept in view, 

 it appears probable that these form a group intermediate 

 between Santalaceas and Olacineae, into both of which fami- 

 lies some of the genera gradually pass. The main characters 

 of this group, considered with regard to Santalaceas and Ola- 



cineae, I take to be the tendency to singleness of the floral

Genus meo sensu Leptomerise et Exocarpo propinquum ; a praecedente 

 distinguitur inflorescentia, ovario supero, et drupa ecoronata, a posteriore 

 pedunculo fructus immutato, disco, habitu et inflorescentia. Opilia 

 dignoscitur calyce (an semper?), glandulis discretis, et inflorescentia. 

 Habitus quodammodo Opiliae (Groutia) celtidifoliae. 



I have experienced great difficulty in ascertaining from dried speci- 

 mens the exact nature of the ovulum, more particularly as in my notes 

 made at Mergui some years since, it is represented as an antitropous, 

 erect ovulum. But as in the dried specimens, I find the central body 

 to be gibbous on one side, I prefer, particularly as it corresponds with 

 the affinities of the plants, considering it to be analogous to a true 

 Santalaceous ovulum. Otherwise I am not acquainted with any clear 

 mark of distinction between an erect, nucleary, anatropous ovulum, 

 and an antitropous ovulum, otherwise of the same degree of develop- 

 ment, attached to a central placenta, and with its apex presented to the 

 fundus of the ovarium.
