264 PLANTS GROWING IN DRY SOIL. 
when we follow some stone wall toa place where we know a 
spreading patch of /frazses des bois, as the French call the wild 
strawberries, is in bloom. The little plant is, in fact, often 
called wild strawberry. Perhaps we attempt to carry it away, 
but it is indignant at such treatment and its petals droop 
quickly after leaving their shady home. 
SHRUBBY CINQUEFOIL. (Plate CXXXV/Z/,) 
Potentilla fruticosa. 
FAMILY COLOUR ODOUR RANGE TIME OF BLOOM 
Rose. Yellow: Scentless. Eastern states and westward. All summer. 
The flowers of this plant, although larger, are very similar in 
arrangement to those of the common cinquefoil. It seems to 
be the patriarch of the family and has from five to seven long, 
narrow leaflets, which are more flattering in shape to the fingers 
after which it was christened than those of the rest of the 
genus. It also grows as high as four feet, and is very 
shrubby. 
The plant isa good example of the theory that is now ac- 
cepted, and the one through which Goethe appeared on the plat- 
form of science. It is that of the morphology of the suddenly 
arrested branch into the flower. The circular growth of the 
leaves is very similar to that of the sepals and petals, and which 
are in reality nothing but transformed leaves. The calyx hasa 
double row of five sepals, the outer one spreading and the inner 
one bent to give some protection to the naked seeds. There 
are also five petals. The stamens are then naturally in some 
multiple of five. When the growth is very rapid it is some- 
times the case that some of these parts are obliterated. 
Shrubby cinquefoil is most capricious of soil and locality, 
and is said to circle the globe. In the eastern states it favours 
low, moist meadows or even swamps, but chooses drier soil as 
it travels westward, until in Michigan it flourishes in sandy soil. 
Toa classification according to soil its vagaries are not only 
trying, but inexcusable. }
