generally resembling S. nervosa, the leaves narrower, Sepals ride ably 
corolla in Wallich's t e, often 4-2 in, and greatly exceeding it; sometimes co e 
shorter than the corolla, when às species must he distinguished from S. pulchella by 
the larger gland. Corolla-lobes 1_1 in. usually white with blue or black dots, never

half as long as the corolla in Wallich's type. Corol/a-lobes pale-blue with deeper- 
blue nerves and dots, erect and connivent in young fruit ; orbicular depression 
hak, << the base of the corolla, covered by a small scarcely pubescent scale or
