Ahern 840 Sherman, collected in Mindanao in 1901, was determined by Merrill 
(Philip. Bur. For. Bull. 1 (1903) 40) as S. scrobiculata. It should be referred 
to S. guiso: 
Much of our material is sterile and it shows quite a range of variation. The 
mature leaves are usually glabrous or nearly so; but some specimens show leaves 
that are sparsely hairy; and some show a development of stellate hairs on the 
petioles and young shoots and on the midrib on the upper surface of the leaf. 
It is quite probable that there will prove to be more than one species in the 
material listed above, when we have more complete material for study and 
comparison. 
Common names: guijo, betik (Lag.), guisoc (V., Moro), sarai (II.), yamban 
(n.). _ . 
6. Shorea sp. 
This form differs from S. guiso principally in having a dense pubescence 
of grayish color on the underside of the leaves and on the twigs. The 
pubescence is composed of large stellate hairs, such as are found on the 
leaves of S. eximia, S. squamata and S. philippinensis. The leaf-shape 
is very constantly that of S. guiso and the venation seems to be mueh the 
same. The' wood may be slightly harder than that of guijo.

7. Shorea negrosensis sp. nov. Plate XLIY. 
Arbor magna, 40 ad 50 m alta, 2 m diametro. Folia elliptica, oblonga, 
vel ovata; lamina 9 ad 15 cm longa, 4 ad 6 cm lata; petiolo 1.5 ad 2.5 cm 
longo. Nervis secondariis 12 ad 16. Stipulae parvae fugaceae. Pani- 
culae terminales. Petala intus glabra, extus sericea. Stamina circiter 
30 ; filamenta subtus lata et sursum fastigata. Ovarium conoideum pilo- 
sum. Stylopodium 0. Stylus glaber. 
Gregarious in habit. Bark thick, black and fissured. Wood deep-red 
at the heart, the heart taking up a large proportion of the log. Logs often 
rotten at the heart. Base of leaf rounded, apex sharply acuminate. 
Midrib depressed and tomentose above, prominent and pilose beneath. 
Secondary veins prominent on underside of leaf. Tertiary veins parallel 
or reticulate, distinct and with regularly spaced large stellate hairs. This 
gives the underside of the leaf an appearance much like that of almon 
( 8 . eximia), but with a lesser degree of hairiness. When dried, the 
leaves often have a coppery color on the under surface. Stipules small, 
triangular, nerved, hairy, fugacious. Flowers in terminal panicles. Calyx 
and petals with dense grayish or yellowish tomentum on the outside,
