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 laminae narrowed obliquely into the petiolules 

 ut the base, and long acute acumen, '2 cm. in length ; the median folioles 

 are from l'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 cm. 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-jngate bract or small leaf, broadly sheathing at the base,iwith 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 5 ; 

 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 $ 

 flowers of typical structure are mixed with the , 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 cm., 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 case 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.
