An explanation of the nomenclature and _ systematic 
position of the genera Eranthemum and Pseuderanthemum 
has already been given in this work (B. M. t. 8239). The 
genus Pseuderanthemum comprises between 60 and 70 
species, inhabiting the tropics of both hemispheres ; they 
are most numerous in the Indo-Malayan and Polynesian 
regions. The genus is very homogeneous, and the species 
much resemble each other in general appearance. 
Cuirivation.—The treatment most suitable for a large 
number of subtropical <Acanthaceae answers well for the 
species here described. Cuttings are put in early in spring ; 
the plants are grown on under liberal treatment, and the 
growths are stopped as often as is necessary to make them 
bushy. Plenty of sunshine and moisture must be allowed 
while growth is being made. Many of the species of 
Pseuderanthemum may be grown so as to get them in flower 
in winter, when they are of considerable decorative value. 
Among those best suited to this purpose are P. albiflorum, 
Radlk. (B. M. t. 4225); P. Andersonii, Lindau (B. M. t. 
5571); P. cinnabarinum, Radlk. (B. M. t. 5921); P. igneum, 
Stapf (Eranthemum igneum, Linden); and the species now - 
figured, which last may also be grown so as to flower in late 
summer. 
Description.— Undershrub, erect, lax, somewhat hirsute 
with stiffish white hairs; branches terete. Leaves ovate, 
acuminate, base contracted and cuneately decurrent, 2-5 in. 
long, 14-34 in. wide, thin, dark green, sparingly hairy, main 
nerves oblique, 6—7-paired ; petiole slender, 2-1} in. long. 
Inflorescences spiked, terminal or also in upper leaf-axils, at 
first dense, afterwards elongating and interrupted below, 
ultimately 4 in. long, when young comose from the slender 
calyx-lobes and bracts; rhachis somewhat hirsute; cymes 
3—l-flowered, sessile; pedicels rather thick and short or 
obsolete ; bracts subulate, sparingly whitish hirsute, ¢ in. 
long, bracteoles similar but smaller. Calya } in. long, 
glabrous or nearly so, deeply 5-lobed, lobes slender subulate. 
Corolla salver-shaped; tube narrow, nearly straight, pale 
red, sparingly glandular hairy; limb cinnabar red above, 
paler beneath, 1 in. across; lobes oblong or subobovate 
obtuse nearly 4 in. wide. Anthers slightly exserted ; fila-
