mm long. Calyx funnel-shaped, about 2 mm long and wide,

A characteristic species, similar to and manifestly allied to Memecylon 
venosum, but readily distinguished by the characters indicated in the 
diagnosis. The ultimate branchlets are 4-angled and narrowly 4-winged, 
which places the species, according to Cogniaux's arrangement, near M. 
paniculatum Jack, to which M, loheri is otherwise not especially closely 
allied.

A glabrous shrub 2 to 3 m high, the branches terete, brown, 
the branchlets slender, distinctly 4-angled or sulcate, not winged. 
Leaves sessile, ovate to oblong-ovate, coriaceous, 7 to 10 cm long, 
3 to 6 cm wide, narrowed from below the middle to the acumi- 
nate^ apex, the base very broadly rounded, cordate, when dry 
shining on both surfaces, the upper surface brownish-olivaceous, 
the lower much paler; lateral nerves about 10 on each side of the 
midrib, slender, distinct but not particularly prominent, anas- 
tomosing with the somewhat arched submarginal nerves, the 
latter as prominent as the lateral ones. Inflorescence axillary 
and terminal, solitary, peduncled, of very much reduced, sub- 
capitate, few-flowered, simple cymes, the peduncles slender, 
somewhat sulcate, not 4-angled, up to 2 cm long, the flower- 
bearing part of the inflorescence subglobose, less than 1 cm in 
diameter. Calyx cup-shaped, about 3 mm in diameter, trun-
