SCROrnULAKIACE^E. 147 



A small plant, producing a tuft of radical leaves, and generally- 

 sending out a few branches, which root at tlic end and produce a 

 smaller tuft of leaves at this point ; in other respects similar to 

 the primary tuft ; in very luxuriant examples similar stolons are 

 thrown out from these secondary tufts. Petioles £ inch to 2 inches 

 long, niuch longer than the lamina, which varies in breadth, being 

 sometimes scarcely broader than the petiole, at other times nearly 

 \ inch across. Peduncles numerous, \ to 1 inch long, slender, 

 without bracts, recurved in fruit. Calyx cup-shaped, 5-toothed. 

 Corolla white or pale-rose, nearly regular. Capsule sub-globular, 

 half as long again as the calyx, scarcely as large as a hempseed. 

 Plant green, glabrous. _, ,

GENUS VIII— SIB THORP I A. Linn. 



Calyx 4- to 8-cleft. Corolla subrotate, nearly regular ; limb 

 with as many segments as there are divisions in the calyx, or 1 

 more. Stamens as many as the divisions of the calyx ; anthers 

 2-celled. Stigma capitate, entire. Capsule membranous, laterally 

 compressed, 2-celled, opening loculicidally by 2 valves. Seeds 

 numerous, very minute, not winged. 



Smalls herbs, with the stems often rooting at the nodes. Leaves 

 alternate or fasciculate, stalked, roundish-reniform. Flowers very 

 minute, yellow or reddish, on axillary peduncles.
