all along the branches, on pedicels 4 mm. long, with two small bracts at the 
base. Calyx-lobes triangular, 1 mm. long ead 1 mm. broad at the base, 
obtuse to acute and erect in flower. Petals 2°5 by 1°5 mm., the lamina 
reflexed in flower. Stamens with filaments 3 mm. long; anthers minute. 
Style 3-5 mm. long. Ovary 2 mm. long by 1 mm. Pedicels, calyx, and 
ovary thickly gland-dotted. 
This plant approaches some forms of MM. tenuifolia (Sm. ), Mez, but is 
distinguished by the glabrous glandular habit, much smaller leaves, and 
the yellow 4-merous flowers.

Hab. Arfak Mts., 8. W. ridge, 8000’. Fl. Dec. 5986. 
Largest leaf 3°5 cm. by 2°5 cm., with the midrib impressed on the upper 
surface and prominent on the lower. Petiole +5 mm. long. Cymes 
3-4 cm. long, with first ternate, then racemulose branching ; peduncles

leaves being arranged in erect pairs up the chocolate-brown stems, which 
bear numerous inflorescences of the same colour.
