 Species of Ceylon and the South Deccan Peninsula. 



12. S. robusta, Arn. in Hook. Cornp. Bot. Mag. ii. 308 ; stein attaining 

 21 in. shaggy with rufous-brown hair, leaves cordate-ovate sessile with long 

 rufous hairs above and on the nerves beneath, capsule nearly \ in. campanulate 

 trigonous hispid-scabrous 6-nerved, pedicel about | in. Naud. in Ann. Sc. Nat. 

 ser. 3. xv. 327 ; Triana in Trans. Linn. Soc. xxviii. 76. 



CEYLON; Walker ; Adam's Peak, alt., 5000-7000 ft. Thwaites No. 426 partly. 



Branches ascending, round, with harsh or soft hairs. Leaves % in., nearly entire. 

 Calyx-tube with many spreading hairs. Petals ^ in., elliptic, acute, purple. Anthers 

 attenuated, long. Capsules 3-6 to the raceme, nearly sessile. Seeds with raised 

 points, raphe exeurrent on one side near the top. 



VAB. glabricaulis, Thwaites ms. ; stem 4-angular nearly glabrous, leaves sessile 

 nearly glabrous beneath. Ceylon ; at Boputalanda, Central Provinces, Thwaites No. 

 3955. 



13. S. Harvey i, Thwaites Enum. 107 ; stem 18 in. erect with ascending 

 quadrangular branches nearly glabrous, calyx-tube glabrous, anthers subacmni- 

 nate but much shorter and less attenuate than in S. robusta. 



CEYLON, Central Province, alt. 6000-7000 ft. ; Thwaites No. 2974. 



Leaves f in., rhomboid-oblong, unequal-sided, obtuse or subcordate at the base, 

 glabrous on both surfaces, denticulate ; petiole about ^ in. Racemes short. Petals 

 % in., elliptic, acute, purple. Triana in Trans. Linn. Soc. xxviii. 76 has erroneously 

 called this species S. Hartwegi, and altered the naming of Thwaites' examples so as 

 to confuse it with No. 12 S. robusta.

 branching nearly glabrous, leaves ovate and ovate-lanceolate serrate, capsule 

 in. funnel-shaped trigonous 6-ribbed smooth usually shorter than the pedi- 

 cel. Naud. in Ann. Sc. Nat. ser. 3. xv. 325; Thwaites Enum. 109; Triana in 

 Trans. Linn. Soc. xxviii. 76.

Leaves % in. (sometimes much smaller), thin, sparsely pilose above, minutely glan- 

 dular-dotted and sometimes thinly hairy beneath ; petiole f in. Calyx-tube nearly 

 glabrous, or with a few lax hairs. Petals ^ in., ovate, acute, mauve. Anthers oblong, 

 attenuated upwards. Seed with raised points, raphe exeurrent on one side near the 

 top. See the remarks under No. 4 S. zeylanica. 



VAB. rostrata, Thwaites Enum. 108 (sp.) ; anthers more attenuated, leaves less 

 serrated, flowers usually a deeper colour. Ceylon, alt. 1000-2000 ft. ; Thwaites No. 

 2644. 



15. S. rhombifolia, Thwaites Enum. 108; glabrous, stem 1-2 ft., leaves 

 rhomboid narrowed at both ends crenate-serrate, capsule \ in. funnel-shaped 

 trigonous 6-ribbed about as long as the pedicel. 



CEYLON ; at no great elevation, Thwaites. 



Leaves 1 in., 3-nerved the lateral nerves near the margin, minutely glandular- 

 punctate ; petiole | in. Petals \ in., purple-mauve. Seeds with raised points, raphe 

 exeurrent on one side near the top.
