112 SIR DIETRICH BRANDIS—AN ENUMERATION 
mens the pedicels are shorter than the calyx in the same way as 
in the Perak specimens, but the racemes are often long pedun- 
culate. Hopea bracteata and Haviland's no. 2225 have branchlets 
and petioles pubescent, while no. 1045 is entirely glabrous. The 
Borneo specimens have large hairy pits at the base of the leaf. 
Of the Borneo specimens the fruit is not known. 
The close affinity of Balanocarpus and Hopea is well illus- 
trated by this species. The Borneo specimens, of which the 
flowers only are known, present no external characters that 
would separate them from section Dryobalanoides of Hopea. 
For anatomical examination of this interesting species, no 
material is unfortunately at present available.

Borneo (Beccari, nn. 2511, 2892). Probably also Penang 
(Curtis, n. 426). 
Petioles glabrous; tertiary nerves parallel and reticulate ; 
calyx after flowering imbricate, pubescent outside, glabrous 
inside ; sepals thickly coriaceous; (petals and anthers unknown); 
ovary narrowed into short style, similar to B. penangianus ; no 
stylopodium. Fruit cylindric, grey tomentose ; base enclosed by 
the thickened and somewhat enlarged calyx-segments.

Borneo (Beccari, n. 2888). 
Entirely glabrous, except the fruit ; leaves thickly coriaceous, 
elliptic, acuminate, margin revolute; secondary nerves 5-6 pairs, 
arching ; tertiary nerves parallel and reticulate. Fruiting- 
calyx enclosing base of fruit, glabrous, shining ; segments thickly 
coriaceous, the two outer a little smaller than the inner. Fruit 
one inch long, almost cylindric, acuminate, with numerous raised 
longitudinal lines, slightly velutinous; pericarp erustaceous. 
Hypocotyl nearly as long as embryo, the cotyledons therefore 
attached to it at the base of fruit. Both cotyledons bifid to 
base, thick, fleshy, mainly filled with starch. Hypocotyl lying 
between the two lobes of the anterior cotyledon, but so as to 
touch the inner edges of the posterior lobes (fig. 25). Between
