concealed by the short, truncate connectives. Carpels about 30, 
crowded, oblong, pubescent, 1 to 1.2 mm long, the stigma sessile, 
truncate, broad, obscurely cleft; ovule solitary, basal. Torus 
flat. Fruit ellipsoid, about 2 cm long, rounded, the pericarp 
somewhat wrinkled when dry, thin, glabrous; seed solitary, very 
hard when dry, about 1 cm long, ruminate, the pedicels in fruit 
2.5 to 3 cm long.

The species is anomalous in Polyalthia in its short, very thick, incurved 
petals, which are, however, entirely free, valvate, not at all arched over the 
stamens although incurved, and its sessile truncate stigmas. The flowers 
at anthesis are depressed-globose and about 1 cm in diameter, although the 
petals at all stages are entirely free. It perhaps belongs in the alliance 
with Polyalthia persicaefolia Benth. & Hook. f.

number. 
This species is not a Unona (Desmos), but belongs in the section Monoon 
of Polyalthia, its carpels having a single basal ovule. It is very similar 
and very closely allied to Polyalthia cumingiana Merr., and a series of 
specimens may show the two to be identical. Polyalthia agusanensis differs 
from P. cumingiana in its distinctly broader petals and in its rather more 
numerously nerved leaves. The original description of Elmer’s species 
is faulty as to the length of the outer petals being indicated as 4 mm when 
manifestly 4 cm was intended. The type number is 18654, not 8654 as 
cited.

Polyalthia pinnatinervia Elm. Leafl. Philip. Bot. 5 (1913) 1736. 
The type of Polyalthia grandifolia Elm. is Elmer 7358, from Leyte, a 
specimen with very immature fruits; the type of P. pinnatinervia Elm. is 
Elmer 13611, from Agusan, Mindanao, a specimen with flowers. While the 
specimens are not directly comparable in all characters, one being with 
young fruits and the other with flowers, I can detect no specific differences, 
and am confident that but a single species is represented. 
POLYALTHIA MERRITTII (Merr.) comb. nov. § Eupolyalthia. 
Unona merrittii Merr. in Philip. Journ. Sci. 1 (1906) Suppl. 190. 
This species is apparently a Polyalthia rather than a Unona, and seems 
to be closely allied to the Malayan Polyalthia glauca (Hassk.) Boerl. in Ic. 
Bogor. 1 (1899) 104. It is represented by the following specimens: Luzon, 
Province of Tayabas (Principe), Merrill 1081: Province of Camarines,
