RUMPHIUS'S HERBARIUM AMBOINENSE 



it might possibly be a small-flowered species of Dysoxylum. In 

 the plate the fruits are drawn entirely out of proportion to the 

 leaves according to the measurements given by Rumphius. 



MELIACEAE OF UNCERTAIN STATUS 



Vidoricum silvestre Rumph. Herb. Amb. 1: 173, t. 67. 



This disposition of Vidoricum silvestre is suggested chiefly because the 

 seeds, as figured by Rumphius, almost certainly pertain to some meliaceous 

 plant. The description of the species is indefinite, and from it alone no 

 rational idea of the plant can be obtained.

Frutex scandens, ut videtur dioicus, ramulis junioribus inflor- 

 escentiisque leviter cinereo-pubescentibus, foliis subtus ad costa 

 nervisque plus minusve ciliato-hirsutis ; foliis oblongis, charta- 

 ceis, usque ad 16 cm longis, integris, utrinque subaequaliter an- 

 gustatis, basi acutis, apice breviter acuminatis, nervis utrinque 

 circiter 7, subtus prominentibus, in siccitate nigrescentibus ; 

 cymis axillaribus, solitariis, pedunculatis, usque ad 2 cm longis, 

 laxis, paucifloris; floribus $ 5-meris, circiter 3 mm diametro, 

 sepalis extus parce pubescentibus, petalis oblongis, truncatis, 

 vix retusis, glabris, glandulis pubescentibus. 



A scandent shrub. Branches terete, glabrous, slender, 

 brownish or somewhat reddish-brown, lenticellate, the branchlets 

 similar in color, slightly pubescent with pale, scattered, usually 

 appressed hairs. Leaves chartaceous, oblong, 11 to 16 cm long, 

 4 to 6 cm wide, entire, subequally narrowed to the acute, equi- 

 lateral, or rarely slightly inequilateral base, and to the distinctly 

 but rather shortly blunt-acuminate apex, brown or olivaceous- 

 brown when dry, the upper surface shining, quite glabrous, 

 the lower surface of nearly the same color, ciliate-hirsute with 

 scattered, spreading, pale hairs on the midrib, and to a less 

 extent on the primary nerves, reticulations, and sometimes even 

 the margins ; lateral nerves about 7 on each side of the midrib, 

 prominent, curved, blackish when dry, faintly anastomosing, 

 the reticulations distinct; petioles about 4 mm long, sparingly 

 grayish-pubescent, ultimately glabrous. Cymes axillary, soli- 

 tary, slightly grayish-pubescent with short appressed hairs,
