ALABASTEA BOENEENSIA. 209 



A glabrous .-tree, the branches and branehlets terete, pale- 

 brownish, smooth, or the thin bark on the branches forming 

 flakes, the ultimate branehlets about 2.5 mm. in diameter, 

 thickened at the nodes. Leaves opposite, elliptic to ovate- 

 elliptic, coriaceous, 9 to 11 cm. long, 4.5 to 6 cm. wide, the 

 apex prominently and rather abruptly acuminate, the acumen 

 about 1 cm. long, blunt, the base rounded to somewhat acute, 

 margins slightly recurved, the upper surface smooth, pro- 

 minently shining, castaneous, minutely and rather densely im- 

 pressed-puncticulate, the lower surface dull, brown or reddish- 

 brown, glandular; nerves numerous, slender, obscure, about 

 equally prominent on both surfaces, the primary ones about 

 30 on each side of the midrib, spreading, scarcely more distinct 

 than are the secondary ones and the reticulations, uniting with 

 the equally obscure marginal nerves about 1 mm. from the 

 edge of the leaf ; petioles dark-brown, 7 to 10 mm. long. In- 

 florescences terminal and in the uppermost axils, the flowers 

 very numerous, crowded in dense globose heads 1.5 to 3 cm. 

 in diameter formed of the greatly thickened and shortened 

 branches of the inflorescence. Buds all sessile, oblong-obovoid, 

 5 to 6 mm. long, each group of two, or more usually three, 

 flowers subtended by a whorl of broadly-ovate to oblong-ovate, 

 obtuse to acute bracts and bracteoles, these coriaceous, cas- 

 ,taneous, 1 to 1.5 mm. long. Calyx-tube cylindric or slightly 

 angled by compression, narrowed below, dark-brown, shining, 

 slightly rugose, the lobes 5, 0.5 to 0.8 mm. long, about 1.5 

 mm. wide, rounded. Petals 5, free, orbicular, prominently 

 imbricate, concave, the outer one 2.5 to 3 mm. in diameter, 

 the inner four closely imbricate within the outer one but not 

 at all connate, free, falling as a calyptra, 2 to 2.5 mm. in 

 diameter. Filaments numerous, inflexed.

 February- June, 1914, near the seashore, the flowers white. 



A species at once recognizable by its dense, globose, capi- 

 tate inflorescences. In appearance it is distinctly like various 

 species of Syzygium with densely arranged obscure nerves, and 

 would certainly be placed in Syzygium by some authors. As 

 the petals are not at all united I have placed it in. the section 

 Jambosa. 



Eugenia kiauensis, sp. nov. § Jambosa.
