2 CLASS DICOTYLEDONS 



conspicuous and either poly symmetric or monosymmetric. The 

 sepals and petals sometimes graduate into one another, and are 

 often spurred, the sepals being 3, 5, or more, and the petals often 

 absent, or 5, rarely 2, 4, or more. The stamens are indefinite in 

 number and hypogynous ; the carpels rarely 1 or 2, generally 3 — 5 

 or more numerous, distinct, and forming either an etaerio of one- 

 seeded indehiscent achenes or a ring of many-seeded follicles. 

 In Actcea there is exceptionally a berry-like fruit. The Order is a 

 numerous one, chiefly characteristic of temperate regions. Many 

 of them are garden favourites. Species of Aconiium yield valu- 

 able drugs.
