This species is well characterized by its rather large, oblong, 
brown leaves, the nerves being prominent but evanescent before 
reaching the margins and the reticulations being obsolete; and 
its axillary or solitary, compressed, oblong-ovate fruits which 
are about 1.5 cm long, compressed and rugose when dry. 
PLECTRONIA OLIGOPHLEBI A sp. nov. 
Frutex glaber; foliis crassissime coriaceis, oblongis, usque ad 
5 cm longis, in siccitate brunneis vel atro-brunneis, brevissime 
petiolatis, utrinque acutis, subtus in axillis haud glandulosis, 
nervis utrinque 2 vel 3, subtus prominulis, adscendentibus, dis- 
tinctis, reticulis obsoletis; inflorescentiis axillaribus, solitariis, 
umbellatis, umbellis 7- ad 12-floris, brevissime pedunculatis vel 
superioribus sessilibus ; floribus parvis, circiter 4.5 mm diametro. 
A glabrous shrub, 4 mm high ( fide Ramos), the branches 
somewhat thickened, the branchlets somewhat 4-angled, the in- 
ternodes 1 cm long or less. Leaves oblong, very thickly coria- 
ceous, brown or blackish-brown when dry, slightly shining, 
smooth, 3.5 to 5 cm long, 1.2 to 1.6 cm wide, subequally narrowed 
to the acute base and apex; lateral nerves 2 or 3 on each side 
of the midrib, ascending, distinct, slightly raised on the lower 
surface; stipules broad, 1.5 to 2 mm long; petioles 1 mm long 
or less. Umbels axillary, solitary, 7- to 12-flowered, the pe- 
duncles 2 mm long or less, the upper inflorescences often sessile ; 
pedicels 4 to 5 mm long. Flowers green, about 4.5 mm in dia- 
meter, the calyx about 2 mm in diameter, shortly 4-toothed. 
Corolla-tube about 1 mm long, the lobes broadly ovate, acute, 
spreading, about 2 mm long.

mit, apparently at or above an altitude of 900 meters. 
The alliance of this species is manifestly with Plectronia gy- 
nochthodes Baill. (P. umbellata K. Schum.), from which it is 
distinguished by its smaller, fewer-nerved leaves and its very 
shortly peduncled to sessile umbels. It is less closely allied to 
Plectronia ramosii Merr., the latter species differing in its 1 
longer petioles, peduncles, and pedicels, and in numerous other 
characters.
