OF THE DIPTEROCARPACER. 105 
Sepals lanceolate, slightly overlapping in bud, grey tomentose 
outside, pubescent inside. Stamens 15; anthers linear, glabrous; 
valves nearly equal, the two posterior bluntly apiculate; appendage 
of connective longer than anther, thick spindle-shaped, with a 
long point. Ovary-cells half-immersed in the broad obconical 
receptacle, narrowed into an elongated hairy stylopodium. Wings 
of fruiting-calyx—the 3 outer broader, 8-9-nerved, with pro- 
minent reticulate veins between the longitudinal nerves, similar 
to the venation in the fruiting-sepals of P. stellata and P. lucida. 
4. PARASHOREA WARBURGII, sp. nova. Fructus globosus, 
acuminatus, tomentosus, calycis segmentis 3 maximis 8-10-nerviis 
basin versus angustatis 2 paullo minoribus, pericarpio tenui 
erustaceo, cotyledonibus zqualibus usque ad basin bifidis. 
Philippine Islands: Mindanao, plain forest of Dagatpan 
{ Warburg). 
Only fruit known, which, however, undoubtedly belongs to 
this genus. Fruit on a thick obconical pedicel 7 in. long, 
globose, i in. diam., tomentose, with the remains of a slender 
tomentose stylopodium š in.long. The three larger wings of 
fruiting-calyx up to 5 in. long and š in. broad; the two smaller 
segments narrower and 3-j the length of the larger segments. 
Longitudinal nerves of the larger segments 8-10. Pericarp thin, 
erustaceous. Cotyledons equal, bifid to base, the 4 lobes pris- 
matic with 2 flat and 1 rounded face. — Radicle half the length of 
embryo. Cells of cotyledons closely packed with minute starch- 
grains. 
9. ISOPTERA, Scheffer. 
Essential characters :—Calyx-segments imbricate, unequal in 
flower. Petals linear, many times longer than calyx-segments. 
Stamens 30 36; anther-cells equal; appendix of connective ciliate. 
Ovary and stylopodium densely tomentose ; style short, glabrous. 
Fruit supported by the spreading coriaceous sepals, the 3 outer 
orbicular, larger than the inner. Cotyledons plane-convex, en- 
closing the hypocotyl, the cells filled with fat. 
I have had no opportunity of examining the anatomical struc- 
ture. According to Pierre (tab. 252) the internode has at its 
base 16-18 ducts in the pith; near the top of the node two 
lateral, and afterwards an apical leaf-trace separate from the 
central cylinder. Burck, l. c. 188, states that the resin-ducts of
