Buchnéra bilabiàta, Thunb. fl. cap. p. 465. Buchnéra lineari- 
folia, Schum. pl. guin. 279.? Easily distinguished from the 
other species by the imbricate floral leaves, and the remarkably 
dilated apex of the tube of the corolla. Flowers from 6 to 8 
lines long. Plant taller and more erect than $$. densiffora.

nearly simple ; leaves lanceolate-linear, erect, rather adpressed, 
hispid : floral ones similar, about equal in length to the calyxes;

Stature and habit almost of S. Thunbérgii, 3, but less rigid; the 
flowers rather larger, and like S. làtea. The whole plant is 
very hairy, and scarcely turns black on drying. 
Elegant Striga. Pl. 1 to 1 foot. 
10 S. ru`rea (Lour. coch. p. 22. ? Benth. l. c.) hairy, very 
scabrous ; leaves long-linear, spreading : lower ones lanceolate; 
spikes elongated; calyx 10-15-striped ; corolla glabrous: lobes 
of the limb obovate: upper lip emarginate, about half the 
length of the lower lip. 27. G. Native of the Indian Penin-

seldom turning black on drying. Corolla yellow. 
Yellow-flowered Striga. Pl. 1 to 1 foot. 
11 S. pHe@nicea (Benth. 1. c.) humble, villous, very scabrous ; 
leaves lanceolate, obtuse, spreading ; spikes dense; calyx 10- 
striped; corolla glabrous: lobes of the limb obovate : upper

néra coccinea, Benth. scoph. ind. p. 40.  Corollas scarlet. 
Habit of S. làtea, but much more glabrous, and usually dries 
black. This is supposed by Hooker to be the one described by 
Petit Thours as parasitical ; but Bentham says it has less that 
appearance than S. litea or S. Thunbérgii, which latter has also 
red flowers. 
Scarlet-flowered Striga. Pl. $ to 1 foot. 
13 S. crasra‘ra (Benth. l. c.) nearly glabrous, scabrous ; 
leaves long-linear; calyx oblong, 10-15-striped ; spike slender ; 
corolla glabrous: lobes of limb oblong : upper lip emarginate, 
about half the length of the lower one. Y. S. Native of the 
East Indies, Nipaul, and mountains of Ava, Wall. ; also in the 
Peninsula, Wall. Buchnéra Asiática, Benth. scroph. ind. 40. 
Lin. spec. 879, partly. This species evidently comes near the 
583 
following, but is distinguished by the glabrous corolla. The 
flowers are said to be bluish. 
Glabrous Striga. | Pl. 3 to 1 foot. 
14 S. Eupwrasiorpes (Benth. 1. c.) smoothish, scabrous ; 
leaves long-linear, quite entire, and few-toothed; calyx oblong,

north; and of Java, ex Blum. bijdr. p. 740. Buchnéra euphra- 
sioides, Vahl, symb. 3. p. 81. Buchnéra angustifdlia, D. Don, 
prod. fl. nep. p. 91. Buchnéra Asiática, Lin. spec. 879, partly.

quite entire, linear, adpressed, strict; calyx somewhat 15-

leaves linear-lanceolate, toothed ; calyx deeply cleft, 10-striped, 
with linear, foliaceous segments; tube of corolla elongated, 
clothed with fine down, incurved towards the apex. X.S. 
Native of Madagascar and Mosambique, Forbes. Nearly allied 
to the preceding, but less rigid, and leaves broader ; calyx 7-8 
lines long; but the corolla is about the same size ; and in the 
var. (J. nearly as large as in Rhamphicdrpa tubifldra, 
Var. 8, grandiflora (Benth. 1. c.) flowers larger.

brous: leaves linear: floral ones lanceolate, ciliated ; calyx 5- 
striped; tube of corolla smoothish, incurved at the middle:

Lin. syst. Didynamia, Angiospérmia. Calyx short, tubu-

salver-shaped; with a slender exserted tube, which is straight 
or a little incurved; limb spreading, nearly equal, 5-cleft; seg- 
ments oblong or obovate. Stamens didynamous, inclosed. Cap- 
sule straight, with rather coriaceous, entire valves, which dehisce 
elastically at maturity, septiferous in the middle.—A frican, 
Asiatic, or American herbs, usually scabrous, becoming black 
on drying. Lower leaves opposite: upper ones alternate: 
lower ones the broadest: upper ones narrower, remote, and, for 
the most part, quite entire: floral ones bractea-formed, usually 
shorter than the calyx. Flowers solitary, sessile, bibracteate, 
disposed in a terminal spike.
