HYDROPHYLLACEJS 249 



No. 2. Pinnatisect ; terminal segment transversely broader than 

 long, trifid with rounded, obtuse, apiculate lobes ; lateral segments 

 obovate. 



No. 3. Pinnatisect ; basal lobes broadly subrhomboid, tri- 

 dentate ; middle pair of lobes irregular, subobovate, apiculate ; term- 

 inal lobe small, obovate, apiculate.

 with apiculate teeth ; middle pair of segments tridentate with 

 apiculate teeth ; terminal segment obovate with a tooth on one

More segments are added to the leaf by segmentation of the 

 terminal lobe as the plant gains in size and strength.
