(King). 
3. P. PAUCINERVIS, sp. nova. Arbor preter inflorescentiam 
glabra. Folia crasse coriacea, ovata, nervis secundariis utrinque 
6 arcuatis, cum costa inferne valde prominentibus. Flores pani- 
culati, pedicellis brevibus. Petala obovata, emarginata. Stamina 
antheris apice 5-mucronatis. Pistillum ovario glabro, stylopodio 
elongato piloso, stylo longe exserto filiformi, stigmate obtuso. 
Luzon; Philippines (Shorea sp. ; Vidal, nn. 79, 1166, 2167). 
Stipules minute, early eaducous. Leaves from a rounded or 
subcordate base; midrib and 6 pairs of arching secondary 
nerves conspicuous; tertiary nerves mostly reticulate. Blade 4— 
6, petiole 1 in. long. Flowers nearly half inch long, on short 
obconical pedicels, in terminal and axillary panicles, the ramifi- 
cations of which, as well as the outside of sepals and petals, are 
grey with dense stellate tomentum. Inside of sepals puberulous. 
Petals spreading. Valves of anthers nearly equal, terminating, 
as well as connective, in 5 nearly equal acute appendages. Style 
glabrous, thickened above; stigma obtuse. Fruit unknown. 
7. Suonxa, Roxb. in Gaertn. f. Carpologia, iii. 47 ; Engler, 
Nat. Pflanzenfam. iii. 6. fige. 123, 124. 
(Including Parahopea, Heim.) 
Large resinous trees ; stipules in a few species large and per- 
sistent, in most small and early deciduous. Leaves coriaceous; 
secondary nerves prominent; tertiary nerves mostly parallel. 
Flowers as a rule in unilateral spikes or racemes, these distichous 
and regularly alternating on the branches of large axillary and 
terminal panicles. Each flower subtended by two mostly 
deciduous, in a few species persistent and conspicuous bracts. 
Sepals strongly imbricate, always hairy outside, and often inside 
also, on the margin ofa broad obconical receptacle. Petals oblong, 
rarely ovate-oblong, hairy on the outside. Stamens generally 15, 
in some species more. Anther-cells generally equal ; connective 
prolonged into a pointed appendage, generally longer than anther, 
sometimes short or wanting. Segments of fruiting-calyx with 
their broad bases tightly enclosing the fruit, the three outer ones
