 ripe, but with uncer-

In Misembryantheraum the leaves are mostly oppo- 

 sitr. intire or the margin somewhat spiny, fleshy and 

 often subcylindrical or triangular in cross-outline; flow- 

 ers jH-rfect and regular, axillary and solitary or some- 

 what corymbose ; calyx gamosepalous, usually with 5 

 unequal lobes and the tube adnate to the ovary; petals 

 very many, in one or more rows, usually linear, white, 

 yellow or' rose-color ; stamens very numerous : ovary 

 most commonly 5-loculed : fruit or capsule opening 

 radially at the summit, hygroscopic: seeds very numer- 

 ous, small. "The capsules are tightly closed in dry 

 weather and open naturally after a rain," writes Sonder. 

 "If thrown in water until it becomes thoroughly soaked 

 and then removed, an old capsule will open out its capil- 

 lary valves, radiatinu' from a center like a star: and will
