Leaves lanceolate ; cup of fruiting-calyx small, enclosing only 
base of fruit. Fruit globose, with numerous raised lines.

Borneo (Beccari, nn. 2533, 3734, 2993). 
Leaves elliptic-oblong, very shortly acuminate. Branches of 
inflorescence and calyx clothed with minute stellate hairs. Cups 
of fruiting-calyx enclosing the base of the fruit only, funnel- 
shaped; segments short, thickly coriaceous, reflexed at apex. 
The structure of flower and seed corresponds with that of the 
other species. Heim bases bis new genus Baillonodendron upon 
the nervation of the leaves and anatomical characters ; neither, 
however, present anything peculiar. The fruit is on a stalk 
(Heim), which is unusual in this order, but does not justify a 
separate genus. The stalk, which I have not been able to examine, 
seems analogous to that of Shorea platycarpa, Heim. The 
fainter intermediate nerves alternating with the secondary nerves 
are also found in the other species. The hispid inflorescence 
and calyx are peculiar, but this only constitutes a specific dif- 
ference.

The essential characters of this remarkable genus are well illus- 
trated in tab. ii. of Heim's ‘Recherches’ (D. zeylanica, Thw.). 
They may briefly be summed up as follows :— Branches of inflores- 
cence glabrous, except in D. congestiflora, Thw. Calyx-segments 
glabrous, imbricate, the two outer and the third larger at time 
of flowering than the two inner, in some species all segments 
equal. Anther-cells equal; connective prolonged into a short 
obtuse clavate or spathulate appendage; style filiform, without 
Stylopodium ; fruit tightly enclosed by the enlarged basis of the 
fruiting-calyx segments, three of which grow out into obtuse 
Wings. Cotyledons auriculate and lobed, flat but folded and 
twisted many times, the testa entering into the folds, filled with
