both sides, a trifle deeper green on the upper usually folded 

 side; fruits or the nut portion greenish; the 3 outer wings 

 larger than the 2 inner ones, all papyraceous, rlavus to flavo- 

 virens in color, strongly venose — "Malibato" in Manobo. The 

 fruits were gathered from the ground under the large old 

 tree, the leaves and wood sample were taken from a foot and 

 a half thick tree near the old or parent tree. Heavy and 

 hard-wood trees the natives commonly call "Malibato" meaning 



bad stone or like a stone.

This tree seems to produce wood of the grade known 



t i-x-*- 



commercially as Yacal." 



Apparently related to Shorea balangeran Burck, but very 

 distinct from that species in shape and venation of leaves and 

 in size of fruit. 



Shorea sp. aff. S. Vidaiiana Brandis 



Large tree. Leaves lanceolate to oblong lanceolate, acu- 

 minate at apex, rounded at base, margin entire, glabrous 

 above; pubescence of scattered, branched, whitish hairs, prin- 

 cipally on the veins beneath. Young twigs and petioles with 

 similar pubescence. Stipules reddish, ovate, pubescent, 4 6 

 mm wide and 6 — 7 mm long, dropping early and leaving 

 distinct scars. Secondary veins about 14 pairs, with shorter 

 intermediate veins, curved, ascending and approaching close 

 t)gether near the margin of the leaf. Tertiary veins parallel 

 and reticulate, not very conspicuous. Leaf blade 5 — 11 cm 

 long, 2.3—1.5 cm broid; petiole 10—12 mm long. Flowers 

 not known. Fruit 10—15 mm tall, 10 — 14 mm in diam- 

 eter. Style projecting, conical, gray tomentose. Longer calyx 

 wings spatulate, reddish brown, 6 cm long, 10 mm wide, 

 with 8 principal longitudinal veins. Wings very thin and 

 oblique, cross wings very conspicuous. Short wings more 

 slender and 2 cm long. 



I cannot be sure whether or not this is really Shorea 

 Vidaiiana Brandis. It differs from the description of that spec- 

 ies iu having a greater number of secondary veins. It is 

 closely related, also, to Shorea Curtisii King, of the Malay 

 Peninsula, but differs from that species in having smaller 

 fruit.
