i?ooi a roundish knob, with several woolly fibres. Her6 smooth. Stem 

 a span high, purplish, simple or branched ; leafy in the lower part. 

 Leaves scattered, on longish stalks, orbicular, peltate, concave, 

 unequally notched or lobed, smooth, very succulent and brittle; 

 the upper ones less peltate, and more deeply cut. Clusters of 

 several pale yellow, cylindrical, crowded, drooping, inodorous 

 Jlowers, with small solitary bracteas. Nect. red. Stam. sliort, 

 in 2 rows, in the mouth of the flower. 



The leaves, applied externally, may, like Houseleek, have a cooling 

 quality, as old herbalists record. Gerarde justly observes that 

 the hot acrid Hydrocotyle was very unluckily used by some in- 

 stead of the Cotyledon. 



2. C. hitea. Greater Yellow Navelwort. 



Leaves deeply toothed; the lowermost slightly peltate. 

 Flowers erect. Root creeping.
