PLATE 344. 
Pentas Wvue, N.H.B. (Kew Bulletin, 1901, p. 123.) 
Natural Order, Rusiacea. 
An erect undershrub, 2 to 4 feet high bearing cymes of white flowers. Stems 
erect, much branched, bluntly quadrangular and furrowed on the sides, the younger 
parts copiously pilose with whitish hairs, older nearly glabrous. Leaves opposite, 
decussate, stipulate, petiolate, lamina reaching to 5 inches long, 2 to 2+ inches 
broad, broadly ovate, lanceolate, margins quite entire, acuminate at apex to a blunt 
point, tapering at base to a winged and channelled petiole, pilose on the veins 
beneath, upper surface with scattered hairs rising from a tubercular base, petioles 
# to 14 inches long densely pilose, recurved and slightly thickened at the point. 
Stipules, several lobed, the lobes subulate, arising from a broad base which con- 
nects the opposite petioles, the central one longest, 4 to 5 lines long. Calyx 
gamosepalous, unequally divided, the lobes 4 to 6, differing much in size, longer 
than the tube, lanceolate to linear-lanceolate, ciliate with whitish hairs, alternating 
with 4 to 6 minute glands, tube turbinate, much enlarged and strongly ribbed in 
fruit. Corolla gamopetalous, 5-lobed, tube cylindrical, widening upwards, longer 
than the lobes, lobes spreading, minutely cuspidate, the whole corolla 5 to 6 lines 
long, pilose externally, hairy in throat, valvate in aestivation. Stamens five, in- 
serted just below throat, anthers linear, 2-celled. Ovary inferior, 2-celled, ovules 
numerous. Style slender, 2-lobed Capsule, sub globose, 8-ribbed, opening at apex. 
Seeds numerous, angular, minutely and closely pitted ; brown. 
Habitat: Narat: Zululand, Ungoya forest, 2000 feet alt, Wylie in Herb. 
Wood, Nos. 7590 and 8480. 
The genus Pentas includes 10 species, of which 7 are natives of Tropical 
Africa, 2 of Madagascar, and the one above described, which is so far as known to 
us the only one in Natal. It has only been found in the locality named, 
where it grows in light shade in the forest. The drawing was taken from a young 
plant in the Botanical Gardens, Durban. In older plants the branches are more 
elongated, and the internodes are longer.

style and stigma; 4, capsule ; 5, transverse section of ovary; 6, node of stem with 
stipules, natural size; all but Hig. 6 enlarged.
