 Pedicels in flower 1-1 (at length 2) lin. long, minutely 2-bracteolate ; 

 nectaries subsessile. Calyx 2 lin. long, whitish glaucous or grey, 

 minutely pubescent ; segments linear-lanceolate, acuminate. Corolla

 pubescent ; lowest lobe broad-ovate, rounded, 3 lin. long and broad. 

 Capsule shortly rostrate, 7-8 lin. long, 2 lin. broad, obtusely quad- 

 rangular, 4-sulcate ; beak 1 lin. long, rather broad and often obtuse. 

 Seeds 1 lin. long, margins very acute, faces faintly rugose, sides broad, 

 transversely rugulose. — S. angustifolium, Engl, in Baum, Kun.en.e-

Very similar to S. angustifolium, but differing in the finer indumentum, the 

 shorter and comparatively broader capsules with a short, broad beak and the larger, 

 less rugose seeds. 



9. S. calycinum, Welw. in Trans. Linn. Soc. xxvii. 52. Stem 

 2-3 ft. high, erect, simple or sparingly branched upwards, with arrested 

 branchlets forming small tufts of leaves in the lower leaf-axils, obtusely 

 quadrangular, sparingly rufo-subhirsute or pubescent and mealy-glan- 

 dular. Leaves subsessile, lanceolate to linear, obtuse to acute at the 

 apex, cuneate at the base, 2|— 1 in. long, 6-2 lin. wide, entire, rarely 

 with 1-2 irregular teeth, finely hirsute above and on the nerves below, 

 at length more or less glabrescent, glaucous from sessile glands below, 

 at least when young ; nerves rather prominent below, 4-5 on each 

 side, very oblique, transverse veins distinct. Pedicels 1J-2 (at length 

 over 2) lin. long, ebracteolate ; nectaries sessile. Calyx 3-3^ lin. long, 

 pubescent and mealy-glandular; segments subulate-lanceolate, finely 

 acuminate. Corolla rose-coloured, obliquely campanulate, 1-1^ in. 

 long, rufo-pubescent ; lowest lobe orbicular, subapiculate, \ in. in diam. 

 Capsule acuminate-rostrate, almost 1 in. long, 2 lin. wide, pubescent, 

 4-sulcate, obtusely quadrangular. Seeds not quite 1 lin. long, margins 

 acute, faces like the broad sides finely or quite obscurely rugose. — Hiern

I find the nectaries to be sessile, not " evidently stipitate," as Welwitsch says. 

 Do Wildeman and Durand (Reliq. Dewevr. 173) indicate this species also from the 

 Upper Cong i, at Kasongo, where Dewevre (919) collected it, who describes the 

 c-orolli as violet with a white tube and a yellow, violet-streaked lip, and states that 

 the natives oil the shore of Lake Tanganyika eat it.
