The petiole is +2 dm. long by 7 mm. broad, pithy, and markedly con- 
tracted immediately below the insertion of the petiolules, which are thick 
and of unequal length, the lateral ones being 1°5 cm., while two of the four 
lateral median are 4 cm., and the central 5-6 cm. long, respectively. The 
leaflets are very unequal in size and shape, the two small lateral ones being 
1:4 dm. by 4 cm., with entire lamine narrowed obliquely into the petiolules 
at the base, and long acute acumen, 2 cm. in length; the median folioles 
are from 1°5-2 dm. by 7°9 cm., rounded at the base, lengthily acuminate, 
entire below and remotely sinuate-dentate above. The. compound in- 
florescence is 1°8 by 4°5 dm., composed of 10 primary rays with involucral 
bracts 2 cm. by 5 mm., the secondary rays varying from 9-11 em. long, and 
bearing 3-16 umbellules, 7 predominating in number ; these secondary rays 
often bear a small bract some distance below the umbellules and show cymose 
branching and often tertiary cymose-umbellate ramifications. The peduncle 
of the inflorescence is +1°8 dm. long, pithy, rising in the axil of a digitate 
3-jugate bract or small leaf, broadly sheathing at the base,:with very unequal 
leaflets. Flowers on pedicels varying in length, articulated under the flowers. 
Calyx-lobes 5, acute, 1 mm. long. Petals obovate-lanceolate, 2 mm. long, 
narrow at the base, with the apex incurved for half the length. Stamens 9 ; 
filaments 1 mm. long; anthers °5 mm. long. Disc crenulate with 2 short 
thick styles 1 mm. long, erect in flower, recurved in fruit. A few o 
flowers of typical structure are mixed with the 3, of which in one case 
8 calyx-lobes and stamens were present, and sometimes the parts were in 
fours. Fruit green when collected, brown when dried, 1°5-1°8 cm. by 
1-4-5 em., the pyrenes separating on maturity. Embryo foliose. 
The only point in which this plant differs from Mackinlaya is the 
structure of the mericarps and the embryo. In Mackinlaya, the former are 
plane on the surface, with thin exocarp and horny endocarp, both well 
differentiated and separating easily; the integument is thick, brown in 
colour, while the embryo is plane, homogeneous, and hard (“albumen 
homogeneum, indurans”). In the present ¢ase the separate pyrenes are 
more oblique, showing excavation on the wings, with no differentiation of 
exocarp and endocarp; the integument is membranous, light brown, and 
transparent; the embryo tapers to the base, is slightly folded, and very soft 
in consistency. As the tapering endosperm does not fill up the cavity in 
the pericarp, a furrowed surface results. I have not examined critically the 
other species of Anomopanax, but macroscopically this difference seems to 
hold for the genus, though not given by Harms in his diagnosis.
