In ins. Sumatra. Specimina misit am. Dr. R. H. C. C. SchefFer, 

 horti Bogoricnsis dignissimus Director, cui sacratam volui. 



This curious plant, of which I have unfortunately seen no flowers, 

 has a twice shorter fructiferous calyx-tube than D. Bcccarii, Dyer, as 

 represented in his figure,* but its shortness is exaggerated by its being 

 thoroughly hidden by the downward production of the backward 

 folded bases of the lobes. In the stigraa it recedes from the generic 

 character, but I really do not know where it is to be placed, unless 

 here. Possibly it may be the type of a distinct genus. I have seen 

 the foliage only of four or five supposed species of Dri/ohalanops from 

 the Malayan Archipelago, which are cultivated in the Euitenzorg 

 Gardens, and there can be no doubt that enormous establishment 

 . V possesses an extraordinary amount of unedited species. 



I take advantage of the occasion to note, from specimens com- 

 municated by Dr. Scheffer, found in the province of Lampong, 

 Southern Sumatra, the characters of the fruit of TFopea menga- 

 rawan, Miq., of which the flowering phmt has alone been described 

 hitherto. f 



Calycis fructiferi lobis glaberrimis vernicosis oblongo-obovatis 

 obtusis tcnuiter membranaccis 9-nerviis 22 lin. longis 5-6 liu. latis 

 basi nucem amplectante tiimidis. 



This species is very closely allied indeed to the Cambodian plant 

 I lately referred in this Journal (with a diagnosis^ to //. micrantha, 

 Hook, fil., but it differs by its lepidote branchlets, larger leaves more 

 widened towards the base, the midrib prominent above as well as 

 beneath, and the longer fruit-wings ; and as in these very points it 

 agrees better with Hooker and Dyer's descriptions than does the plant 

 of Pierre, I can scarcely doubt that the Borneau and Sumatra trees 

 are identical. I therefore desire to substitute the name of Jl. Pierrei 

 for that I had conjecturally given. Hooker's paperj was read in June, 

 1860, and Miquel's Prodromus of the Sumatran Flora published in 

 the same year, so that there is a question as to precedence. But if 

 Hasskarl's Petalandra really falls into Hopea, as maintained in the 

 '* Genera," though doubted by A. De Candolle (and I have only fruit- 

 ing specimens myself, which are insufficient to settle the question), 

 then the specific name micrantha would remain with it. Both belong 

 to a small group, distinguished under the sectional name oi Bri/oha- 

 lanoidcs by Miquel, yielding resin, and differing by a peculiar habit and 

 ecostulate finely-veined leaves from the majority of Hopece.
