ALABASTRA BOENEBNSIA. 233 



Flowers terminal, about 5 cm. long, 5-merous, siibumbellately 

 arranged, sessile, 3 to 5 at the apex of each branchlet, the in- 

 florescence sessile or very shortly peduncled, the bracts cori- 

 aceous, acuminate, ovate-lanceolate, 4 to 5 mm. long, the two 

 bracteoles subtending each flower similar but much smaller. 

 Calyx 10 to 11 mm. long, the lobes ovate, obtuse, 6 mm. long. 

 Corolla-tube about 3 cm. long, slender below, gradually widened 

 in the upper one-half and about 7 mm. in diameter at the 

 throat; lobes spreading, oblong, obtuse, about 1.5 cm. long; 

 anthers somewhat exserted, about 2 mm. long. 



-Sarawak, Mafang road, Native collector 6S6 (Bur. Sci.), 

 June 29, 1911, with the local name nijatu. Perhaps referable 

 here is Hose 1^6 from the Baram District, April,- 1895, of which 

 I have a very fragmentary specimen. In this specimen the 

 leaves are relatively wider, about 11 cm. long and 7 cm. wide, 

 while the flower is slightly longer than in the type, the corolla 

 being 5.5 cm. in length. 



The alliance of this species is manifestly with Fagraea 

 ooovata, Wall., from which it is distinguished by its differently 

 shaped, slenderly and acutely caudate^acuminate leaves. By 

 the latter character it is also distinguished from the B'ornean 

 species, Fagraea lieteroplujlla, Blume, F. rostrata, Blume, and 

 F. splendens, Blume.
