Cult. Being mostly annual plants, growing naturally in sandy 

 soil near the sea, the seeds should be sown in dry warm situa- 

 tions in spring : or it is perhaps better to sow them on a hot- 

 bed in spring, and plant them out towards the end of May into 

 the open border ; or they may be grown in pots and set in the 

 greenhouse or in a frame.

LIN. SYST. Icosandria, Monogynia.\ Calyx of 2 permanent, 

 oblong-lanceolate, mucronate, concave, stiff sepals, propped by 

 8 or 9 imbricate bracteas, similar to the sepals. Petals 5, obo- 

 vate, mucronulate. Stamens numerous, about 40 ; filaments 

 filiform, monadelphous at the base ; anthers erect, 2-celled. 

 Ovarium oblong, 1 -celled. Style filiform, thickened upwards; 

 stigmas 4, but usually 5, linear. Capsule 1-celled, 5-valved. 

 Seeds numerous, compressed, broadly winged, each fixed by a

 alternate, terete, oblong, obtuse, fleshy leaves, bearing hairs in 

 the axils. Flowers solitary, terminating short or elongated 



branches, with white sepals and petals ; and having the filaments 

 purple at the base, and the anthers and stigmas yellow.

LIN. SYST. Dodec&ndria, Monogynia. Calyx of 2 sepals (f.
