date, slightly compressed', glabrous; seeds compressed-ovate, brown, 

 wrinkled.

 around Lake Alexandrina- 



144. Euphrasia flZ5fl5,!F.Muell.; dwarf, annual; glandulously downy ; 

 leaves sessile, in outline ovate-cuneate, laciniate or pinnatifid ; lobes of 

 the leaves oblong or linear, blunt; spikes very short, few-flowered; 

 calyx tubulose-campan'ulate, the lobes blunt, about as long as the tube ; 

 tube of the corolla hardly exserted, of equal length with the limb, the 

 lobes of the lower lip emarginate, of the upper retuse; anthers scantily 

 bearded, tbe cells of all short and equally spurred ; capsule orbicular-

It differs by its annual root from all other Australian and Tasmanian 

 species, by its almost equally spurred anthers from the European, by the 

 bearded anthers from the South American, and respectively by the same
