198 XXI. MALVACE.K. \Sida. 



S. rupestns, Miq. I.e. 241, which I have not seen, nppears from the description to be 

 the same species with the young parts pubescent. S. Hookenana is periuips nearer allied 

 iA appearance to 3Todioia carol iniana than to Slda triloba, Cav., but dilFers from both in 

 the structure of the fruit; S. triloba is moreover a perennial, with dilFerenlly-shapcd leaves 



and a dissimilar venation of the calyx.

 large capitate stigmas. Capsule depressed-globular, opening loculicidally ni 

 3 valves bearing the dissepiments in tlieir centre, rarely splitting also septici-
