PORTULACACEAE (PURSLANE FAMILY) 



Herbs, with succulent leaves, and essentially regular but unsymmetrical 

 flowers, viz., sepals fewer than the petals ; the stamens opposite the petals when 

 of the same number, but often indefinite ; otherwise nearly as Chickweeds. 

 Sepals 2. Petals 5, or sometimes none. Stamens mostly 5-20. Styles 2-8, 

 united below, or distinct, stigrnatic along the inside. Pod 1-celled, with few or 

 many campylotropous seeds rising on stalks from the base. Embryo curved 

 around mealy albumen. Insipid and innocent herbs, with entire leaves. Co- 

 rolla opening only in sunshine, mostly ephemeral, then shriveling. 



* Calyx free, persistent. 



1. Montia Petals 3-5, usually unequal, sometimes slightly connate at the base. Stamens aa 

 many. Ovules 2 or 3. Roots fibrous.
