65. WATERLEAF FAMILY. Order HYDROPHYLLACEiE. 



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

 much like those of the Borrage Family, except as to the ovary, which is globular and only 



one-celled and bears the 

 few or many ovules and 

 seeds on the wiills (pari- 

 etal), or on two projections 

 from them. In Waterleaf, 

 Nemophila, &c., the two 

 placentas, beaiing the few 

 seeds, broaden and make 

 a kind of lininij 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 some Ke- 

 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 without appendages or teeth between the divisions, large in fruit, {Ellisia) Elusia. 



Calyx with 5 reflexed teeth between the divisions, {Nemophila) *KEMORniLA. 



Leaves alternate : appendages of the calyx none or minute : stamens long. 



Mostly annuals: seeds on the walls of the pod, or two narrow placentas, {Pliacclia) Phacelia. 

 Perennials, Avith scaly-toothed rootstocks. Seeds 1 to 4, enclosed in a membrane 

 which lines the pod. Flowers white or bluish, clustered: filaments 

 bearded below, {Ilijdroplnjllum) Waterleat.
