The plate of Burmann (Fl. Ind. t. 41, fig. 1) is good, and represents a plant not of 

 the genus Ruellia. In the Addit. to Mant. 515 (1771), Linnsus says his Ruellia repens 

 was Burmann, t. 41, fig. 1 ; it may be more correct to call this species R. repens, 

 Blume. Nees, in DC. Prodr. XI. 370, says his RosteUularia sarmentosa had the 

 capsule "4-seeded from the base," so that there is probably some error in the 

 RosteUularia sarmentosa issued from Buitenzorg.

Ruellia j:rostrata, Lam. Encycl. VI. 349 (of. Hook. f. Fl. Br. Ind. IV. 411), differs 

 a little from R. repens, Linn., by having larger flowers and capsules, and the leaves 

 usually rather larger. In the Kedah example, Eidley, n. 5750, the flowers are more 

 th'in 1 in. long, and the capsules more than -To in. long ; and Ridley has issued it as 

 " R. prostrata " ; the habit and small leaves are typical R. repens. 



[R. angustiflora, Benth. & Hook. f. Gen. PL II. 1079 (R. angustifoUa, Lindau in 

 Engl. <fe Prantl Pflanzenfam. IV. 3 b, -Sll), is a large-flowered American Ruellia, which 

 appears to spread from gardens in Malaya ; it was collected in Penang by Stoliczka, 

 in Singapore by Deschamps and Hullett, n. 176.]
