xi, c, 2 Merrill: Notes on the Flora of Borneo 75 
nuiter acuminatis, basi acutis, eglandulosis, subtus distincte re- 
ticulatis, 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 2b0, 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, f ewer-nerved, rather slenderly acuminate leaves, 
the reticulations distinct on the lower surface. To Pimeleodendron borneense 
Warb. I refer Hose 206, 295, and Native collector 10^8 (Bur. Sci.), all 
from Sarawak. 
SCORTECH 1 N I A Hooker f. 
SCORTECHiNIA ARBOREA (Elm.) comb. nov. 
Alchornea arborea Elm. Lead. Philip. Bot. 4 (1911) 1274. 
Alcinaeanthus arboreus Pax & K. Hoffm. in Engl. Pflanzenrich 63

Alcinaeanthus philippinensis Merr. in Philip. Journ. Sci. 7 (1912) 
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 5 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 
6 Engl. & Prantl. Nat. Pfianzenfam. 3 5 (1890) 118.
