 Buchnera bilabiata, Thunb. fl. cap. p. 465. Buchnera lineari- 

 folia, Schum. pi. 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 S. densiflbra. 

 Corollas red.

9 S. E'LEGAXS (Benth. 1. c.) hairy, very scabrous, strict, 

 nearly simple ; leaves lanceolate-linear, erect, rather adpressed, 

 hispid : floral ones similar, about equal in length to the calyxes; 

 calyx 10-striped ; tube of corolla downy; lobes of limb ob- 

 long ; upper lip bifid, a little shorter than the lower one. Tf. . G. 

 Native of the Cape of Good Hope ; in Caffreland, Drege. 

 Stature and habit almost of S. Thunbergii, /3, but less rigid ; the 

 flowers rather larger, and like S. lutea. The whole plant is 

 very hairy, and scarcely turns black on drying. 



Elegant Striga. PI. i to 1 foot. 



10 S. LU'TEA (Lour. coch. p. 22. ? Benth. 1. c.) hairy, very 

 scabrous ; leaTes long-linear, spreading : lower ones lanceolate ; 

 spikes elongated ; calyx 10-1 5-striped ; corolla glabrous : lobes 

 of the limb obovate : upper lip emarginate, about half the 

 length of the lower lip. i/ . G. Native of the Indian Penin- 

 sula, Wight ; Bengal, Wall. ; Saharampur, Royle ; Macao, ex 

 herb. Banks ; Canton, Lour. Buchnera hirsuta, Wall. Benth. 

 scroph. ind. p. 41. Buchnera Asiatica, Lin. spec. 879. partly. 

 Habit loose and branchy, or when young more stiff" and simple, 

 seldom turning black on drying. Corolla yellow. 



lW/o-flowered Striga. PI. i to 1 foot. 



1 1 S. PHCENICEA (Benth. 1. c.) humble, villous, very scabrous ; 

 leaves lanceolate, obtuse, spreading; spikes dense; calyx 10- 

 striped : corolla glabrous : lobes of the limb obovate : upper 

 lip emarginate, about half the length of the lower lip. 11. S. 

 Native of the Indian Peninsula. Buchnera phosnicea, Wall, ex 

 Benth. scroph. ind. p. 41. Very nearly allied to S. lutea, but 

 the flowers are said to be red. 



/ferf-flowered Striga. PI. \ to 1 foot. 



12 S. COCCI'SEA (Benth. 1. c. p. 364.) smoothish, scabrous; 

 leaves long-linear ; calyx oblong, 10-striped; spikes loose; co- 

 rolla glabrous : lobes of the limb obovate: upper lip emargin-

 Banks. Campuleia coccinea, Hook, exot. fl. 3. t. 203. Buch- 

 nera coccinea, Benth. scoph. ind. p. 40. Corollas scarlet. 

 Habit of S. lutea, but much more glabrous, and usually dries 

 black. This is supposed bv Hooker to be the one described by 

 Petit Thours as parasitical ; but Bentham says it has less that 

 appearance than S. lutea or 5. Thunbergii, which latter has also 

 red flowers. 



.Scarkf-flowered Striga. PI. | to 1 foot. 



13 S. GLABRA'TA (Benth. 1. c.) nearly glabrous, scabrous ; 

 leaves lon^-linear : calyx oblong, 1 0-1 5-striped ; spike slender ; 

 corolla glabrous : lobes of limb oblong : upper lip emarginate, 

 about half the length of the lower one. I/ . S. Native of the 

 East Indies, Nipaul, and mountains of Ava, Wall. ; also in the 

 Peninsula, Wall. Buchnera Asiatica, Benth. scroph. ind. 40. 

 Lin. spec. 879, partly. This species evidently comes near the 



following, but is distinguished by the glabrous corolla. The 

 flowers are said to be bluish. 



Glabrous Striga. PI. i to 1 foot. 



14 S. EDPHRASIOI'DES (Benth. 1. c.) smoothish, scabrous;

 north; and of Java, ex Blum, bijdr. p. 740. Buchnera euphra- 

 sioides, Vahl, symb. 3. p. 81. Buchnera angustifolia, D. Don, 

 prod. fl. nep. p. 91. Buchnera Asiatica, Lin. spec. 879, partly.

 with linear, foliaceous segments ; tube of corolla elongated, 

 clothed with fine down, incurved towards the apex. 11 . 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. j3. nearly as large as in Rhamphicdrpa tubiftbra. 



Var. /3, grandiflora (Benth. 1. c.) flowers larger. 

 Forbet's Striga, PI. 1 to 2 feet.

 brous ; leaves linear : floral ones lanceolate, ciliated ; calyx 5-

LIN. si ST. Didynamia, Angiospermia. Calyx short, tubu- 

 lar, obscurely 10-nerved, with 5 short teeth at apex. Corolla 

 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. African, 

 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.

 of the B.juncea, distinguished by its peculiar habit ; B. hispida
