370 XCII, SCROPHULARIACEX (HEMSLEY AND SKAN). [ Alectra. 
sessile, rigid, thick, ovate-oblong or lanceolate, the largest about 4 in. 
long, equalling the internodes, rather obtuse, entire or furnished witha 
pair of small teeth near the middle, setulose, especially on the margin 
and midrib on the underside. Flowers solitary in the axils of the oppo- 
site leaves or bracts, very shortly pedicellate; floral-leaves or bracts 
shorter than the flowers, similar to the leaves; bracteoles linear- 
lanceolate, about 2 lin. long, setulose. Calyx hispid, about 4 in, long, 
10-ribbed, nearly equally 5-lobed ; lobes oblong, obtuse, shorter than 
the tube. Corolla about } in. long, narrow-campanulate, constricted 
close above the ovary; lobes very short, rounded, notched. Stamens 
nearly equal; filaments filiform, bearded close under the anthers ; 
anther-cells almost equal, mucronulate. 
Upper Guinea. Lagos: Yoruba, Willson. 
Our specimens are evidently full length, as one at least has roots, but they may 
be from starved plants, and the normal dimensions may be larger. 
16. A. aurantiaca, Hemsl. An annual, parasitic herb, rough 
with warted or tubercled bristles, interspersed with softer hairs, 2-4 in. 
high, branching from the base. ‘Primary stem subterranean, bright 
orange in colour”; branches slender, alternate. Leaves crowded, 
apparently all alternate, sessile, rather thick, narrow-lanceolate or 
spathulate, the longest about 1 in. long, obtuse tapering to the base, 
few-toothed. Flowers shortly pedicellate, yellow, solitary in the axils of 
the upper leaves or bracts, about 3 in. long; bracts similar to the 
leaves, longer than the flowers, smaller upwards, adnate to the base 
of the pedicel; bracteoles linear, acute, about } in. long, thinly clothed, 
as well as the calyx, with long soft hairs. Calyx thin, about 4 in. 
long, 10-nerved, nearly equally 5-lobed; lobes triangular, scarcely 
acute, about as long as the tube. Corolla obliquely campanulate, about 
Zin. long, veined, 5-lobed; lobes rounded. Stamens nearly equal; 
filaments all bearded, the longer very strongly ; anther-cells slightly 
unequal, apiculate. Ovary glabrous; style longer than the stamens, 
club-shaped above the middle, strongly recurved.—Bopusia scabra, 
Hiern in Cat. Afr. Pl. Welw. i. 772, not of Presl. 
Lower Guinea. Mossamedes: in sandy, moist, and bushy ‘places by the 
River Bero, Welwitsch, 5809! 
This has the characters of Alectra, including yellow flowers, a marcescent, per- 
sistent corolla, and a clavate, recurved style. Bopusia scabra, Presl (Graderia 
scabra, Benth.), also differs in being perennial and woody at the base and in having 
pink flowers and a deciduous corolla. 
17. A. trinervis, Hemsl. An erect, hispid, not tuberculate, herb, 
8-15 in. high. Stems slender, weak, simple or forked. Leaves opposite, 
except in the inflorescence, distinctly stalked, rather thick, ovate or 
oblong-lanceolate, or the lowermost smaller and nearly orbicular, largest 
scarcely 1} in. long, obtuse or rounded, entire or with a few small teeth, 
3-nerved, hispid on both surfaces, Flowers few, shortly pedicellate, 
about din. long. Bracts or floral-leaves ovate-oblong, mostly as long 
as the flowers. Bracteoles shorter than the calyx, linear. Calyx softly
