Polyalthia obliqua , Hook. fil. & Thoms., FI. Ind. 188. 
Borneo, sine loco (Lowe in Herb. Kew). 
.Distrib. Chittagong, Malacca, Sumatra.

S.E. Borneo: Banjermasin (Motley). 
Distrib. Malay Peninsula. 
Polyalthia oblonga , King, l. c., 65. 
Sarawak (Beccari, 1621); Mt. Koum (Haviland, 1711); 
Saribas Paku (Haviland, 8149). 
These forms have more persistently silky petals than

Distrib. Malay Peninsula. 
Polyalthia Havilandii , Boerh, Ic. Bogor. lxvi.

Sarawak : Kuching (Haviland, 105, 420, 1057, 2217); 
Miri River (Hose, 72). 
Petals yellow, purple at base. 
Distrib. Assam, Sylhet, Malay Peninsula, Sumatra.

slight difference in the form of the fruit, but I think it 
is specifically the same, as King makes it. 
Polyalthia eriantha , n. sp. 
Young parts woolly, hairy, yellowish. Leaves elliptic 
acuminate, base narrowed thinly coriaceous glabrous 
above, minutely pubescent beneath ; nerves nine to ten 
pairs, inconspicuous above, elevate beneath; transverse 
nerves subhorizontal parallel; reticulations fine, 20-30 
cm. long, 8-10 cm. wide ; petiole thick pubescent, 1 cm. 
long. Flowers solitary, axillary entirely velvety woolly ; 
pedicel thick, 7 mm. long; bract ovate; sepals ovate
