8. R. Goetzei, Stapf. Whole plant glabrous. Young branches 
stout, subangular, brown when dry. Leaves in whorls of 3-4, shortly 
petioled, oblong- or elliptic-lanceolate, shortly acuminate, more or less 
attenuate at the base, very variable in size, up to 1 ft. long and 4 in. 
broad, chartaceous ; midrib channelled above, stout beneath; secondary 
nerves up to 30 or more on each side, subhorizontal, straight or the 
upper curved ; reticulation faint, lax; petiole hardly any or up to $ in. 
long, stout. Flowers very shortly pedicelled in few-flowered (always?) 
clusters on the ends of the secondary or tertiary rays of lax compound 
umbels; peduncle up to 24 in. long; primary rays #-1} in. long; 
secondary rays }—} in. long. Calyx not quite } lin. long, cup-shaped, 
d-toothed. Corolla-tube 1} lin. long, villous at the mouth ; lobes broad- 
ovate, obtuse, scarcely } lin. long. Carpels connate at the base. Fruit 
unknown.

The discrimination of this and the three preceding species is not quite satis- 
factory owing to the scanty material. Further investigation will show how far the 
characters derived from the shape, size and nervation of the leaves may be relied 
upon. The degree of division of the calyx, whether 5—partite with segments dis- 
tinctly overlapping at the base, or merely 5-toothed, will probably be found of 
greater taxonomic value. 
9. R. Mannii, Stapf in Kew Bulletin, 1894, 21. A shrub, 6—9 ft. 
high, perfectly glabrous; youngest branches quadrangular, soon rounded, 
with more or less conspicuous decurrent lines. Leaves in whorls of 
4-3, very unequal in size, oblong; abruptly contracted into a narrow 
linear acumen (4 to 1 in. long), gradually narrowed into the petiole, 
the longer ones 5-9 in. long, 2-3 in. broad, thinly membranous ; 
secondary nerves almost horizontal, 12-16 on each side; veins quite 
obscure ; petioles 2-8 lin. long. Flowers in small few-flowered pseudo- 
umbels ; peduncle about 1 in. long, very slender ; pedicels 1—2 lin. long. 
Calyx 1 lin. long; segments linear-lanceolate. Corolla-tube 24 lin. 
long, villous at the mouth; lobes ovate, obtuse, } lin. long. Carpels 
connate at the base ; style slender, glabrous. Fruit a simple obliquely 
ovoid much-compressed drupe or an obcordate twin drupe, 4-5 lin.
