65. WATEELEAP FAMILY. Order HYDROPHYLLACE^. 



Herbs with lobed, compound, or toothed and mostly alternate leaves ; the regular flowers 

 much like those of the Borrage Family, except as to the ov?.ry, which is globular and only 



one-celled and bears the 

 few or many ovules and 

 seeds on the walls (pari- 

 etal), or on two projections 

 from them. In Waterleaf, 

 Nemophila, &e., the two 

 placentas, bearing the few 

 seeds, broaden and make 

 a kind of lining to the 

 pod. Corolla bell shaped 

 or wheel-shaped ; its lobes and the stamens always 5. Style 2-cleft above. The AVater- 

 leaf furnishes our principal plants of the family that are common wild. But soire Ne- 

 mophilas and Phacelias, from Texas and California, are showy garden annuals. 



Leaves opposite, at least the lower ones. Stamens not projecting beyond the corolla.

Calyx with 5 reflexed teeth between the divisions, {Nemdphila) *Nemopi-iila.
