CALYCIFLOR^ 205 



There may be no petals, as in the Burnets and Lady's 

 Mantle, the former wind-pollinated. The stamens 

 are numerous, or two, three or four times the number 

 of petals, turned inwards in bud, perigynous, inserted 

 with the petals, or on the disc, in one or more rows. 

 The anthers are small and usually didymous. The 

 disc lines the calyx-tube. The pistil is usually 

 apocarpous and superior, rarely syncarpous and 

 inferior when the calyx-tube is adherent to the ovary. 

 The carpels are few or numerous. The carpels may 

 be distinct when the plant is in flower or combined 

 into a single five-celled ovary. The style may be 

 lateral, or at the base distinct, or united at the base. 

 The stigma is simple, rarely feathery. The fruit is a 

 pome (in Pyvus), or may consist of one or more 

 drupes (Rubus), drupels, achenes {Potentilla), follicles, 

 or a berry or capsule. 



The honey is concealed. Usually the anthers are 

 ripe first. Some species are wind-pollinated. A 

 large number with edible fruits have the fruits and 

 seeds dispersed by birds. 



In this group are included many useful fruit trees, 

 over one hundred blackberries, and many favourite 

 garden flowers. 



Wild Strawberry {Fragaria vesca). 



Every person, it may be presumed, has recollec-

 were made in search of the luscious scarlet fruits of 

 the wild strawberry, in some woodland glade where
