SCROrnULAUIACE-H. 117 
A small plant, producing a tuft of radical leaves, and generally 
sending out a few branches, which root at the 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 J inch to 2 inches 
long, much longer than the lamina, which varies in breadth, being 
sometimes scarcely broader than the petiole, at other times nearly 
J inch across. Peduncles numerous, J 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 THORPI A. Linn. 
Calyx 4- to 8-cleft. Corolla snbrotate, 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.

alternate or fasciculate, stalked, roundish-reniform. Flowers very 
minute, yellow or reddish, on axillary peduncles. 
This genus of plants was named after Professor John Sibthorp, the famous
