90 SIR DIETRICH BRANDIS—AN ENUMERATION 
Sect. IV. PrNANGA. 
Fruiting-calyx with 3 long wings; stamens 15; anthers short; 
appendage of connective not ciliate, sometimes scabrous at the 
end. In many species the cortical leaf-traces run through the 
whole length of the internodium. 
Many species of this section have on the underside of the 
leaves a peculiar coppery colour. This is particularly noticeable 
in species with glabrous leaves, such as Shorea Pinanga, Schetf., 
Gysbertsiana, Burck, macroptera, Dyer, acuminata, Dyer, lepidota, 
Bl., Bakeriana, Heim, and pauciflora, King. The character is 
not, however, peculiar to this section, for S. brachyptera, Heim, 
Schefferiana, Hance, Singkawang, Burck, and Beccariana, Burck, 
of sections Brachyptera, Eushorea, and Anthoshorea, show the 
same peculiarity, as well as S. Maranti of section Mutica. 
A. Series macroptera.—Ovary glabrous ; stylopodium pubescent ; 
appendage of connective in most species stout, acute, and 
not much longer than anther.

(1872) 308 ; King in Journ. Asiat. Soc. Beng. lxii. pars 2 (1893),

Perak; Singapore; Borneo (Lowe; Beccari, n. 2891). 
Glabrous, except inflorescence and youngest shoots. Stipules 
small,caducous. Leaves thick, coriaceous, shining on both sides, 
elliptic-oblong. Secondary nerves curved, 10-14 pairs; tertiary 
nerves parallel, but not distinct. Blade 4-6, petiole 3 in. long. 
Spikes with a tendency to become unilateral by torsion. Buds 
short, conical. Filaments of the 5 inner stamens longer, the 
anthers of these with a very minute appendage; appendage of 
the 10 outer as long as anther. Ovary glabrous; stylopodium as 
long as ovary, tomentose; style short, filiform. The 3 outer 
fruiting-sepals broadly auricled, firmly adpressed to the fruit, 
and here marked by a smooth convex area. The smaller fruiting- 
sepals often considerably enlarged. Embryo channelled on out- 
side; hypocotyl nearly as long as embryo. Both cotyledons bifid 
to base, the radicular concave, embracing the other. Cells filled 
with oil and starch. 
The Borneo specimens, including Beccari 2891, do not differ 
specifically. Structure of embryo of Perak specimens like that 
described by Heim. Galls resembling cones on this species.
