Tristania decorticata, sp. nov. ^ Eutristatiia. 



A tree 15 to 20 m. high with alternate, glabrous, acuminate, petioled 

 leaves, and axillary cymes shorter than the leaves, the pentadelphous 

 stamens in groups of threes, opposite to and about as long as the petals, 

 the bark shredding freely, giving the trunk a naked appearance. Branches 

 grayish brown, the branchlets reddish brown, glabrous. Leaves G to 10 cm. 

 long, 2 to 3 cm. wide, tapering at both base and apex, the latter slightly 

 acuminate, the acumen blunt, both surfaces shining, the lower pale, sparingly 

 and minutely glandular punctate, the margins reflexed; nerves numerous, 

 obscure; petioles about 1 cm. long. Cymes glabrous or minutely puberulous, 

 4to 6 cm. long, the pedicels 2 to 3 mm. long. Flowers white, about 4 mm. 

 in diameter. Cal.^-x obscurely 5-toothed, pubescent inside. Petals 5, orbic- 

 ular, glabrous, not clawed. Stamens 1.5, in five groups of three each, the 

 filaments slightly imited below, the middle one of each group slightly 

 longer than the lateral ones. Ovary densely pubescent, subglobose, more 

 than i superior, 3-celled, each cell with many ovules. 



Type specimen: Tinauan River, Province of Tayabas (Infanta), Luzon 

 (787 Whitford), September, 1904. A tree growing in the hill forests 

 along the river at altitude of from 100 to 200 m. above the sea, said by 

 the collector to be common in the locality where the specimens were taken. 

 No species of the genus, which is largely developed in Australia, has 

 previously been found in the Philippines. 



MI]LASTOMATACE.^. 



Astronia meyeri, sp. nov. 



A tree about 8 m. high with elliptical-oblong, sub-5-nerved leaves, which 

 are densely fulvous furfuraceous beneath, short denselj' flowered panicles, 

 and 5-merous flowers. Branches terete, dark brown, glabrous, scarcely 

 thickened. Leaves 10 to 20 cm. long, 6 to 8 cm wide, narrowed regularly 

 to the acute base and apex, or the apex very slightlj' acuminate, green and 

 glabrous above, beneath pale brown and densely covered with thin papery 

 scales; nerves 5, the inner three prominent, the marginal ones not more 

 prominent than the transverse nerves; petioles 3 to 5 cm. long, glabrous. 

 Panicle bright red, densely fulvous furfuraceous, 6 cm. long, the branches 

 stout, spreading or ascending, densely flowered, the lower ones 4 cm. long. 

 Flowers red, odorless, subglobose, 3 to 4 mm. in diameter, the calyx teeth 

 five, triangular, acute, regular, 1.5 mm. long. Petals 2 mm. long. 



Type specimen: Mount Mariveles, Province of Bataan, Luzon (2840 

 Meyer), March, 1904. A very distinct species, reaching a height of 8 m. 

 and a diameter of 15 cm., growing in forested ravines at an altitude of 

 about 1,200 m. above the sea. 



Medinilla involucrata, sp. nov. 



A scandent shrub, more or le.ss stellate-plumose pubescent, with opposite 

 7-nerved leaves, short axillary few flowered racemose inflorescence 2 to 

 4 cm. long, the 5-merous flower.s subtended by two large persistent bracts. 

 Branches light gray, glabrous, the branchlets very densely ferruginous 

 stellate-plumose pubescent. Leaves elliptical <)l)long to broadly lanceolate.
