Sub-family II. RHINANTHIDE^. Corolla with the upper lobes never exterior 



in bud. Inflorescence centripetal. 



Corolla-tube short, equal to the calyx which is deeply 5-fid. Leaves toothed. 



ERINUS. 



Leaves alternate. Stamens 2 or 4, stigma 2-lobed DIGITALIS. 



Corolla almost regular. Leaves opposite. Stamens 2, diverging ; stigma 



capitate VERONICA. 



Stamens 4 converging. Upper corolla lip entire or notched BARTSIA. 



Stamens 4 converging. Upper corolla lip with 2 spreading lobes EUPHRASIA. 



Stamens 4, in pairs. Upper lip slightly hooded ODONTITES. 



Calyx large, inflated. Leaves toothed, opposite. Seeds winged. RHINANTHUS. 

 Leaves opposite. Seeds not winged, 1-2 in each cell MELAMPYRUM. 



SCROPHULARIA L. 



S. peregrina L. Annual, glabrous, 1-2 ft. high. Stem hollow, square, 

 often reddish. Leaves ovate-cordate. Calyx much shorter than the pedicel, 

 with acute lobes not scarious at the borders. Flowers in axillary bunches, dark 

 purple-brown, small. 



Shady places among rocks and ruins. April-June. Found all along the 

 Riviera near cultivated ground, and perhaps introduced with the olive and the 

 vine. 



S. lucida G. G. = S. provincial!* Rouy. Biennial, glabrous and shining, 

 1-3 ft. high. Stem angular. Leaves bipinnatifid, on very short pedicels. Calyx- 

 lobes very scarious. Flowers in a terminal panicle, purplish-brown. 



Stony places and arid fields, widely spread. May-July. 



S. canina L. (Plate XXIII). Plant 1-2$ ft. high, glabrous, nearly simple, with 

 a loosely branched panicle of small reddish-brown flowers. Upper lip of corolla 

 one-third as long as the tube. Leaves pinnatifid, with few, distant, narrow, incised 

 segments. Ardoino says it differs from the last only by its small linear staminal 

 appendage and by its smaller flowers. He adds that it is much less common 

 than lucida in the same localities, and occurs at Menton and Gourdon ; but 

 Bicknell, on the contrary, says in the Bordighera district lucida is the rare one. 

 His " single specimen, however, has very small flowers, while the numerous plants 

 examined from the whole district, with the linear appendage, have flowers and 

 leaf segments of very variable dimensions ". Several botanists have recorded 

 S. canina from the Var, but Albert and Jahandiez doubt its existence in that 

 Department, and think it has been confused with S. lucida. 



Stony places in the hills and on the littoral of les Alpes-Marit. April-May.
