In rich mould, and under favourable conditions, its loaves assume a greater 
the stall: rises several inches in height, and all its parts expand in proportion. 
A- it approaches the sandy shores of the sea, it becomes almost stunted, and produces 
small dark-coloured leaves and minute short-stalked flowers. In counting the cumber 
of Bowers produced on one head under these various circumstances, we find that both 
the ligulate and tubular flowers vary from twenty to forty or fifty in number ; the colour 
of the ligulate Sowers is also very variable, from white tinged with pink to a deep pink 
!v showing any white whatever. In the cultivated garden Daisy this is very 
evident ; the tubular flowers become almost, if not quite, obsolete, and their place is 
taken by ligulate flowers, which assume a deep pink colour. In the variety known 
bv the name of "hen and chickens," little flower-buds are formed in the axils of the 
3 ; sometimes as many as ten or twelve of these minute daisies surround the 
parent flower; thus suggesting its familiar name. 
GENUS XXII— E RIGERON. Linn. 
Anthodcs hcterogamous and radiant, many-flowered. Pericline 
hemispherical or campanulate or sub-cylindrical, consisting of 
numerous rows of imbricated herbaceous phyllarics. Clinanth 
slightly convex, naked, pitted. Florets of the disk perfect or male, 
regular with a tubular-funnelshaped corolla, sometimes surrounded 
by tubular female florets; those of the ray female, in numerous 
rows, all with narrow ligulate corollas. Achenes compressed, not 
ribbed, often pubescent. Pappus of a single row of hairs with 
smaller ones intermixed, or with a distinct outer pappus of short 
hairs or scales. 
Ilerbs with narrow entire usually sessile alternate leaves and 
military or corymbose or paniculate anthodcs, with the llorets of 
the disk yellow, those of the ray white or purple, sometimes in- 
conspicuous. 
The derivation of the name of this genus is from epi (cri), an intensive particle, 
or tap (ear), early, and yeptav (yeron), old, in allusion to the receptacle, which soon 
becomes like a grey head.
