RUMPHIUS'S HERBARIUM AMBOINENSE 



Sepals 5, lanceolate, about 10 mm long, 3 mm wide, narrowed 

 upward, subacute. Petals as long as the sepals, oblong-lanceo- 

 late, outside densely pubescent with pale-brownish, shining, ap- 

 pressed hairs, inside uniformly and densely hirsute with reflexed 

 hairs, the apical 2 mm cut into few narrow lobes, usually two 

 lateral slender ones on each side with a central somewhat stouter 

 one. Stamens about 45, the filaments scabrid, 2 to 2.5 mm long ; 

 anthers linear, scabrid, 4.5 to 5 mm long including the slender 1 

 to 1.5 mm long awn that terminates one cell. Ovary ovoid, 

 densely pubescent, 2-celled; style 4 to 5 mm long, pubescent 

 below. 



It is by no means certain that this is Arbor rediviva of Rumph- 

 ius, although the plant figured and described by Rumphius is 

 manifestly an Elaeocarpus. In the species above described the 

 leaves are larger than in Arbor rediviva, rounded or cordate at 

 the base, not acute, and do not present the peculiar protuberances 

 (galls?) shown by Rumphius. It was by Loureiro, FL Cochinch. 

 (1790) 663, referred to Dicalyx cochinchinensis Lour., but this is 

 a species of Symplocos and judging from the description is 

 entirely different from Arbor rediviva Rumph.

A tree about 12 m high, glabrous except the slightly appressed- 

 pubescent younger parts and inflorescence. Branches terete, 

 reddish-brown, glabrous, the younger ones somewhat angled, 

 brownish-olivaceous, minutely and rather sparingly pubescent. 

 Leaves alternate, narrowly oblong, firmly chartaceous, suboliva- 

 ceous, of about the same color on both surfaces and shining when 

 dry, 12 to 15 cm long, 3 to 5 cm wide, subequally narrowed to the 

 acute base and to the blunt apex, the tip sometimes slightly refuse 

 and minutely apiculate, margins distinctly crenulate; lateral
