creeping (under water); leaves opposite, connate and sheathing at base, 
digitately partite into many slender, filiform, elongate, entire lobes 5. 
pedune. slender, axillary and terminal; invol. uniseriate, of 4—5 broad,

Has. In shallow pools at Greenpoint, near Capetown, W. H. H. (Herb. D., Hk.) 
A very remarkable species with the aspect of a Myriophyllum. At first sight the 
leaves appear to be whorled, many thread-like leaves in each whorl ; but the whorl 
is really composed as above described, of two opposite, connate leaves, cleft to the 
base into many shreds. Leaf-lobes 1-1} inch long, not } line diam. Heads 3-4 
lines diam. 
2. C. coronopifolia (Linn. Sp. 1257); ascending or decumbent, gla- 
brous; leaves loosely sheathing at base, broadly linear or sublanceolate, 
irregularly toothed or pinnatifid, rarely subentire, obtuse ; sheath not 
bearded, with a reflexed, often toothed margin; pedunc. naked or with 
1-2 small leaves ; inv.-scales numerous, linear, obtuse, 3-nerved, membr.

Stems numerous, 10-12 or more inches in length, the longer ones trailing and

variable in shape, sometimes with a few long lobes. Heads bright yellow, 3-4 lines 
diameter. 
3. C. pusilla (Th. ! Cap. 695); glabrous, erect, slender ; leaves alter- 
nate, loosely sheathing at base, pinnati-partite, the lobes linear, acute ; 
pedune. naked or with 1-2 small, simple leaves; inv.-scales few, broadly 
elliptical or oblong, obtuse, membrane-edged ; ray-fl. uniseriate, stipitate ;
