the lobes or teeth slightly imbricated. Corolla gamopetalous, funnelform, saucer- 
shaped, campanulate or rotate, the limb 5-parted, convolute in the bud. Stamens 
5, inserted on the tube of the corolla and alternate with its lobes; filaments slender

nally dehiscent. Ovary superior, mostly 3-celled; ovules 2-<% in each cavity, 
amphitropous; style simple filiform; stigmas 3, linear. Capsule mostly loculi- 
cidally 3-valved. Seeds various, sometimes winged, sometimes enveloped in muci- 
lage and emitting spiral tubes when wetted ; endosperm abundant; embryo straight ; 
cotyledons flat ; radicle inferior. 
About 20 genera and over 200 species, most abundant in western America. 
Calyx distended and at length ruptured by the ripening capsule. 
Calyx scarious between the lobes. 
Corolla salverform; leaves opposite, entire. 
Seeds not mucilaginous when wetted; mostly perennials with large flowers; leaves 
opposite. : 1. Phlox,
