ROSE FAMILY 



Roots. — Fibrous, sending out summer runners that root 

 at the tip. 



Stem. — Slender, with silky hairs, at first decumbent 

 or prostrate, afterward frequently erect. 



Leaves. — Petioled, compound, 

 really three-parted, but apparently 

 five-parted because the lateral 

 leaflets are cleft; leaflets serrate, 

 pointed. 



Flowers. — Yellow, solitary, on 

 slender stems, borne in the axils 

 of the leaves. 



Calyx. — Deeply five-cleft with 

 bracts between the teeth, thus ap-

Corolla. — Of five broad, rounded 

 petals, notched at the apex and 

 showing the hairy green calyx. 



Stamens. — Many; filaments 

 slender; anthers small. 



Pistils. — Many, forming a dense 

 little bunch of green in the centre 

 of the flower. 



Fruit. — A head of akenes.

 are side by side, sometimes intermixed. Structurally, 

 there is not much difference between a Potentilla and 

 a Strawberry blossom, but practically there is a great
