Gen. Char. Calyx (fig. 1.) inferior, of 2 oblong, pointed, de- 

 ciduous sepals. Corolla (fig. 2.) of 4 roundish-obovate, undulated, 

 crumpled, spreading, deciduous petals, much larger than the sepals, 

 with short claws, two opposite ones rather the smallest. Filaments 

 (figs. 3 & 4.) numerous, hair-like, short. Anthers roundish, ter- 

 minal, of 2 lobes. Germen (fig. 5.) superior, cylindrical, or some- 

 what compressed, longer than the stamens. Style none. Slir/ma 

 large, blunt, permanent, of 2 or 3 cloven, compressed, downy lobes. 

 Pod (figs. 6 & 7.) linear, very long, of 2 or 3 linear concave valves, 

 opening from the top to the bottom, and as many cells. Seeds 

 (figs. 9 & 10.) numerous, convex at the outer side, pitted in regular 

 lines (fig. 9.), without a crest, disposed irregularly in 2 rows in 

 each cell, being sunk in the hollow of a spongy or membranous 

 partition (see fig. 7, and fig. 8, c. c. c.), connected with the linear 

 marginal receptacles, (fig. 8. a. a.) which are placed between the 

 edges of the valves, and bear the seeds on short stalks. 



Distinguished from other genera, in the same class and order, by 

 the 2-sepaled calyx ; the 4-petaled corolla; the 2- or 3-celled ^>ocZ; 

 and the dotted seeds. 



Three species British.

* From Glaucos, Gr. in mythology, the name of a fisherman who leaped into 

 the sea and became a sea-god ; also sea-green or glaucous, in allusion to the 

 colour of the plants and their habitation by the sea-side. G. Don.
