groups:  (I)  the  Virginian  group,  including  F.  Virginiana,  the 
common  field  and  meadow  strawberry  of  the  Eastern  States,  with  its 
varieties ;  (2)  the  vesca  group,  including  the  Old  World  strawberry 
and  the  American  form,  called  by  Porter  F.  Americana ;  (3)  the 
Chilian  group,  to  which  belongs  the  Chilian  species  with  all  its 
cultivated  varieties,  and  the  North  American  species,  native  of  the 
Pacific  Coast,  with  its  varieties. 
In  Colonial  times  the  wild,  or  Virginian,  strawberry,  with  its 
several  varieties,  was  cultivated  in  American  gardens,  but  of  late 
years  has  been  supplanted  almost  entirely  by  the  numerous  deriva- 
tives of  the  Chilian  species,  although  wild  strawberries  are  still 
gathered  in  considerable  quantities  in  the  meadows.  F.  vesca  grows 
in  the  northern  part  of  the  United  States,  but  is  not  so  common  as 
the  Virginian  species.

Macroscopic  Structure.- — The  cultivated  strawberries  (F.  Chilo'ensts) 
are  usually  of  large  size  (often  3  to  5  centimeters  in  diameter),  and 
bear  the  achenes  in  deep  depressions. 
Berries  of  the  wood  species  (F.  vesca)  are  of  small  size  (seldom 
over  1  centimeter  in  diameter),  and  bear  the  achenes  in  shallow 
depressions. 
Berries  of  the  Virginian  species  are  of  about  the  same  size  as  the 
wood  strawberries ;  but  like  the  cultivated  berries,  the  achenes  are 
deeply  sunken  in  the  receptacle. 
The  receptacle,  the  edible  part  of  the  strawberry,  consists  of  a 
somewhat  fleshy  pith,  a  still  more  fleshy  cortex,  and  between  the 
two  a  narrow  zone  of  fibro-vascular  bundles,  from  which  branches 
shoot  off  through  the  cortex  to  the  achenes.    (Fig.  1,  I.)
