ROSACEAE

 

ROSE FAMILY

 

Herbs, shrubs and small trees, spiny or unarmed, evergreen or deciduous.  Leaves usually alternate and with stipules.  Flowers mostly bisexual and regular, solitary or clustered.  Sepals and petals at edge of a flower tube (hence perigynous) which is lined or rimmed with and glandular disc.  Sepals 5 (4), often with alternating bractlets; petals 5 (4 or 0).  Stamens mostly in whores or cycles of 5, sometimes numerous and indefinite.  Pistils 1-many, simple, distinct and free from flower tube or united into a 2-5 celled ovary, which may be +/- inferior.  Fruit a follicle, achene, drupe, pome or cluster of drupelets.  Seeds usually without endosperm.

 

Many of our favorite fruits, such as apples, pears, cherries and strawberries, belong to the Rose Family.  (Dale 168,169).

 

A family of over 100 genera and over 3000 species; many of great horticultural value.  (Munz, Flora So. Calif. 739).
