206 ALABASTEA BORNEENSIA. 



lobis 4, oblongo-ovatis, acutis, coriaceis, tubo subaequalibus ; 

 fetalis 4, oblongis ad oblongo-lanceolatis, 4.5 cm. longis, ob- 

 tusis; ovario 4-loculare. 



A glabrous tree. Leaves oblanceolate, thickly coriaceous, 

 pale and shining on both surfaces when dry, up to 75 cm. long 

 and 10 cm. wide, entire, gradually narrowed in the lower one- 

 half or two-thirds, the lamina narrowly decurrent nearly to 

 the base of the petiole, the midrib very much thickened and 

 prominent on both surfaces, on the lower surface toward the 

 base 8 mm. thick;. lateral nerves about 40 on each side of the 

 midrib, very prominent, curved, anastomosing, the reticula- 

 tions more distinct on the upper than on the lower surface; 

 petioles 1 cm. thick, dark-brown, rugose, the wingless portion 

 but 2 cm. long. Spikes apparently elongated and many-flower- 

 ed. Flowers 4-merous, sessile, about 7 cm. in diameter. 

 Calyx 3.5 cm. long, terete, somewhat urceolate, the tube 2 

 cm. long and 8 mm. thick, the lobes 4, coriaceous, oblong- 

 ovate, acute, 1.4 to 1.7 cm. long, about 1.1. cm. wide, not im- 

 bricate. Petals 4, oblong to oblong-lanceolate, 4.5 to 5 cm. 

 long, 1.5 to 1.7 cm. wide, rather thin, obtuse. Stamens very 

 numerous, their filaments united for the lower 5 mm., the free 

 parts about 4 cm. in length. Ovary 4-celled. Style 5 cm.

A most characteristic species manifestly belonging in the 

 same group with B. dolichobotrys. It is well characterized 

 among all hitherto described species- of Barringtonia by its 

 • greatly elongated, thickly coriaceous, entire, many-nerved leaves 

 which taper gradually to the base. My specimen does not 

 ' present the apical portion of the leaves, and only a fragment 

 of the spike. The axis of the spike is pale, much wrinkled, 

 and about 5 mm. in diameter. 



MYRTACEAE. 



Eugenia, Linnaeus. 



This genus is enormously developed in Borneo, as in other 

 parts of the Malayan region, and apparently here, as in other parts 

 of the tropical Orient, a very high percentage of the species are of 

 local occurrence. Up to the present time about forty species of the 

 genus have been described from Bornean material, chiefly by Kor- 

 thals, Blume, and Miquel, but some of the species proposed by Kor- 

 thals are scarcely intelligible without an examination of his types, 

 and some of his types are apparently no longer extant, judging by 

 the fact that Miquel was unable to determine the status of several of 

 the species. In our own collections of Bornean material about 60 

 distinct species are represented, but some of the specimens are not
