NEW AND EAEE MALAYAN PLANTS. 71 



Johor, on rocks 011 Gunong Banang near Batn Pahat 

 (Ridley 11102). 



Allied to S. saxosa of Penang Hill, but the leaves are 

 much narrower, the fruit smaller and it is quite glabrous. 



Sonerila setosa, 11. sp. 



Stem over 8 in. tall, densely bristly, hairy as are the 

 petioles nerves beneath, and edge of leaf, inflorescence and 

 calyx, slightly woody. Leaves very dissimilar, large one ellip- 

 tic, oblong, acuminate base narrowed, unequally cordate, 

 sprinkled with coarse hairs above membranous, nerves ascend- 

 ing from the lower third of the midrib, transverse nervules 

 fine, conspicuous, 4.5 to 5 in. long, 1.5-2 in. wide. Petiole 

 1-1.5; small, leaves orbicular, reniform 1 in. long. Cymes 

 dense, many flowered in all the axils of the small leaves and 

 terminal about an inch long, densely setose, with red bristles. 

 Flowers small, white. Calyx 1 in. long cylindrie, campanulate, 

 red. Petals small, linear, oblong, acute, bristly. Stamens 3, 

 anthers oblong obtuse. Capsule campanulate, muricate, bristly 

 .1 in. long, .2 in. wide, narrowed to its peduncle .2 in. long. 



Pahaxg, on Gunong Tahan (Ridley 16036). 



Allied to 8. caesia for a form of which I first mistook it. 



Medinilla rubicunda, Bl. was based on Jack's Melasto ma rubi- 

 cunda which is Pogonanthera pulverulent a, Bl. 



Xo type specimen of Jack's seems to exist but in Wallich's 

 collection Xo. 4086, is a specimen of Pogonanthera collected at 

 Cape Bachado in Malacca (not Penang as Cogniaux gives it) 

 which is queried for Melastoma rubicunda, Jack, by Wallich, 

 as also is a Medinilla from Silhet. Jack's plant was collected 

 at Singapore. Cogniaux gives Medinilla rubicunda, Bl. as a 

 species and compounds it of the Sylhet plant M. erytliropliylla, 

 Lindl. (Melastoma erythrophylla, Wall. Cat. 4085) and Jack's 

 species. M. rubicunda, Bl. therefore goes out as a synonym 

 of Pogonanthera pulverulenta and the Sylhet plant which does 

 not occur in the Malay Peninsula, retains the name of M. 

 erytliropliylla, Lindl. 



Medinilla venusta, King is apparently a somewhat vari- 

 able plant. King described it as having 8 stamens and acute 

 petals. His type specimens in the Herb. Kew have 8 stamens 

 but I would not call the petals acute, they seem to be rounded. 

 Stapf in Kew Bulletin, 1906, p. 73 describes under M. chio- 

 nantha, a plant which was sent from Perak by Curtis and culti- 

 vated at Kew. It has round petals and 10 stamens, but except 

 for the latter character it is quite like King's, M. venusta from 

 Perak, I conclude it is a variety.
