 licher ; Abyssinia, Brown ; south-east Africa, in the district of 

 Uitenhage, Ecklon ; to Delagoa Bay, Forbes ; East Indian Pe- 

 ninsula, Wight, and plains as far as Saharumpur, Royle. Buch-

2 S. HUMIFUSA (Benth. 1. c. p. 362.) prostrate, scabrous; 



leaves obovate-oblong, obtuse ; spikes short, few-flowered ; calyx 

 5-striped ; ? tube of corolla glabrous. I/ . G. Native of Ara- 

 bia, on the mountains of Hadge, Forsk. Browallia humifusa, 

 Forsk. pi. aegypt. arab. p. 12. Buchnera humifusa, Vahl, symb. 

 3. p. 81. The form of the leaves and procumbent stem, Ben- 

 tham says, will distinguish this from all other species, notwith- 

 standing he has not been able to ascertain whether the calyx be 

 5 -ribbed or not, from the specimens he has examined being so 

 imperfect. 



Trailing Striga. PI. trailing. 



3 S. PARVIFLO'RA (Benth. 1. c.) small, very scabrous ; leaves 

 linear, quite entire, strict ; calyx 5-striped ; corolla downy, with 

 an entire upper lip, which is hardly half the length of the lower 

 lip. I/ . G. Native of New Holland, on the east coast, in 

 Keppel Bay. Buchnera parviflora, R. Br. prod. p. 294. Plant 

 but little branched. Flowers smaller than those of other

 and ciliated with rigid spreading hairs ; calyx 5-striped ; corolla 

 glabrous, with an elongated, slender tube, and an emarginate 

 upper lip, which is about half the length of the lower lip. %. 

 S. Native of Guinea. Euphrasia aspera, Willd. spec. 8. p. 

 197. Buchnera aspera, Schum. pi. guin. p. 280. This differs 

 from S. pus'Ma in the flowers being twice the size, and in the 

 more regular and greater hispidity of the plant,

 Buchnera curviflora, R. Br. prod. p. 294. Allied in habit to

 branched ; leaves long-linear, spreading ; spikes long, loose ; 

 calyx 5-ribbed ; corolla glabrous ; upper lip bifid, a little 

 shorter than the lower one, which is tripartite. I/ . S. Native 

 of New Holland, of the Islands west of Goulbourn's Island, on

 of India as far as Saharampur, Royle. Buchnera Asiatica, 

 Vahl, symb. 3. p. 81. ? Lin. spec. 879. part. Buchnera densi- 

 fldra, Benth. scroph. ind. p. 41. Plant small, rigid, but little 

 branched, in some respects resembling S. Thunbergii. Flowers 

 smaller ; the lobes of the limb shorter and broader. It also 

 differs from that species in the remarkably spreading, often 

 recurved leaves. . 



Dense-flowered Striga. PI. 5 to 5 foot. 



8 S. THUNBE'ROII (Benth. 1. c.) hispid, scabrous, strict, nearly 

 simple ; leaves lanceolate-linear, erect : floral ones lanceolate,
