HYDROPHYLLACEAE. Phacelia Family. 



Herbs or shrubs with opposite or alternate leaves. Flowers complete, reg- 

 ular, 5-merous (except the superior ovary which is 1 or 2-celled), in racemes or 

 spikes (often scorpioid), or capitate, or solitary. Stamens 5, inserted near the 

 base of the corolla, alternate with its lobes, which are imbricate in the bud. 

 Styles 1, often more or less 2-cleft at apex, or 2 and distinct. Fruit a 1-celled 

 capsule or partly or quite 2-celled by the intrusion of the placentae or their 

 union in the axis; valves 2, rarely 4. Seeds few or many. Seed-coat pitted, 

 the cavities regular and honeycomb-like.
