OF THE DIPTEROCARPACEÆ. 43 
A species well marked by dense bright yellowish-brown 
tomentum, densely covering the underside of leaves, making the 
tertiary nerves indistinct. It consists of very minute round 
scales attached in the centre and a small number of dense tufts 
of short stellate hairs. Fruiting-calyx campanulate, not con- 
stricted at mouth. One of the longitudinal nerves of the larger 
segments is less distinct than the two others.

Hills of South-east Borneo. 
Leaves broadly elliptic, clothed beneath with tufts of stellate 
hairs and a dense tomentum of minute star-shaped scales. 
Secondary nerves 20-26 pairs; intramarginal veins and tertiary 
nerves very distinct. Tube and segments of fruiting-calyx 
tomentose. Cotyledons reniform (Korthals). 
Specimens in leaf only, coll. by Motley and Barber in 
Borneo, somewhat resemble 4. costata and Curtisii. Leaves 
oblong-elliptic, underside densely tomentose, sec. nerves 16-20, 
tertiary indistinct ; stipules large, semipersistent.

“ Rasak,” but not the “ Rasak” of Labuan. Labuan (Motley, 
n.291). Hills of South-east Borneo, where this, like A. costata, 
grows gregariously, and is said to attain an immense height 
(Korthals). Bangka (Zeysmann). 
Glabrous, except youngest shoots and inflorescence. Leaves 
elliptic-oblong, second. nerves 10-14 pairs, tertiary mostly reti- 
culate. Anthers mostly ciliate. At the top of pubescent stylo- 
podium 3 short glabrous styles, which often cohere closely. 
8. A. GRANDIFLORA, sp. nova. Arbor ingens. Folia obovato- 
elliptica, superne glabra, infra tenuiter velutina. Inflorescentia 
cum calycibus incano-tomentosa, floribus majusculis racemosis, 
pedicellis calycem dimidium — squantibus. Stamina 20-25. 
Pistillum stylopodio magno glabro, stylo brevi indistincte 
3-dentato.
