NEW AND BARE SPECIES OF MALAYAN PLANTS. 171 



Perak, Tapah (Burn-Murdoch 382). 

 The leaves of this somewhat resemble those of a Calophyl- 

 lum but the terminal flowers and stipules are those of Kayea. 



TERNSTROEMIACEAE. 



Ternstroemia penangiana, Choisy. 



There has been a little confusion as to this plant owing 

 originally to mixture in Flor. Brit. Ind. of two distinct 

 species. Choisy based his species on Wallieh's 4456, Fagraea 

 dubia, a plant with broad obovate very stiff leaves. It has since 

 been discovered on Penang Hill by Maingay and Curtis and 

 has not been found an}'where else. With it has been confused 

 Ery thro chiton Wallichianum of Griffith obtained in Mergui, a 

 totally different plant with thin lanceolate leaves and much 

 larger fruit. This is the P. penangiana, Pierre, Fl. For. 

 Cochin China t. 123 (though he figures the flowers far too 

 small) and the Garcinia acuminata, Wal. Cat. 4871 A. King's 

 description of T. coriacea, Scheff., applies very well to this, but 

 he refers specimens of it collected in the Andamans and Nico- 

 bars by Kurz to T. penangiana. I have seen no specimens of 

 T. coriacea,. Scheff., but the description does not quite suit. 

 The plant more resembles the Javanese T. micro car pa, Scheff., 

 which has nothing to do with T. penangiana to which King 

 refers it. I therefore retain the name Wallichianum for it 

 from Griffith's Ery thro chiton Wallichianum. The plant ranges 

 over the Malay Peninsula from Singapore northwards to 

 Mergui and occurs in the Andamans and Cambodia.

 brous except at base. Flowers large. Calyx narrowly winged, 

 1 in. long, lobes velvety inside, glabrous outside, 3 lobes oblong, 

 blunt .12 in. long, 2 blunt linear oblong .75 in. long. Petals 

 linear, oblong, grey velvety on both sides, .2 in. long. 



Johor, Penyabong (Foxworthy). 



Shorea alba, Eidl. n. sp. 



Tree. 100 feet tall, 4 feet through, glabrous except in- 

 florescence. Leaves lanceolate caudate acuminate, blunt, base 

 shortly narrowed thin coriaceous, above smooth, beneath nerves
