nuiter acuminatis, basi acutis, eglandulosis, subtus distincte re- 

 ticulars, nervis utrinque 4 vel 5; racemis $ solitariis, circiter 

 2 cm longis, pedicellis quam floribus multo longioribus. 



A glabrous shrub or tree, the branches slender, terete, reddish- 

 brown. Leaves alternate, firmly chartaceous to subcoriaceous, 

 brown when dry, oblong, entire, 9 to 18 cm long, 3.5 to 6 cm wide, 

 base acute, eglandular, apex rather slenderly acuminate, the 

 acumen 1 to 1.8 cm long, usually blunt; lateral nerves 4 or 5 on 

 each side of the midrib, prominent, anastomosing, the primary 

 reticulations rather lax, slender, distinct on the lower surface; 

 petioles 1 to 6 cm in length, slender. Staminate racemes solitary, 

 rather slender, about 2 cm long, axillary, springing from a small 

 pulvinus ; pedicels about 3 mm long, the staminate flowers about 

 2 mm in diameter, the calyx at least twice as short as the pedicel. 



Sarawak, Baram District, Baram, Hose 2U0, March, 1895. 



Manifestly allied to Pimeleodendron borneense Warb., from which it 

 is readily distinguishable by its long petioles; solitary, axillary, staminate 

 racemes; and its thinner, fewer-nerved, rather slenderly acuminate leaves, 

 the reticulations distinct on the lower surface. To Pimeleodendron borneense 

 Warb. I ref6r Hose 206, 295, and Native collector 1048 (Bur. Sci.), all 

 from Sarawak. 



SCORTECHINIA Hooker f. 



SCORTECHINIA ARBOREA (Elm.) comb. nov. 



Alchornea arborea Elm. Leafl. Philip. Bot. 4 (1911) 1274. 



Alcinaeanthus arboreus Pax & K. Hoffm. in Engl. Pflanzenrich 63

 Bot. 1274. 

 The genus Alcinaeanthus proposed by me in the year 1912 must now 

 be reduced to the older Scortechinia in spite of certain descrepancies 

 between the original descriptions of the two genera. In proposing the 

 genus Scortechinia Hooker f. placed it in the tribe Phyllantheae with doubt, 

 being uncertain as to the number of ovules in each cell, giving the number 

 doubtfully as two. Pax* considered its position doubtful, and placed it 

 among the uncertain or imperfectly described genera at the end of the 

 family. This was overlooked by me in working out the description and 

 status of my genus Alcinaeanthus. While the female flowers are as 

 yet unknown, I have been able definitely to determine from the examination 

 of very young fruits that there is but a single ovule in each cell, 

 and am confident that the genus was placed correctly by me in the 

 Platylobeae-Crotonoideae-Gelonieae, and very close to the genus Cheilosa 

 Blume. 



It is to be noted, as already mentioned by Pax, that while in the 

 original and, for that matter, subsequent descriptions of the genus Scorte- 

 chinia, the stamens are described as free, in Hooker's 5 figure of the type
