Sy der 6: Frodebo (J.Hartz and C.Ostenfeld). 



Has a peculiar appearanee owing to the difference between 

 the ovate-oval, broad radical leaves, sharply and closely toothed and 

 on long petioles; and the narrow acuminate stem-leaves, coarsely 

 toothed, if at all, and sessile, or with broadly winged semi-am- 

 plexicaul petioles. In the type the teeth of the stem -leaves are 

 sparse, short and rather coarse or are almost wanting; in the variety, 

 the stem-leaves of which are more elongated, the teeth are for the 

 most part developed right at the base, where they are long, ir- 

 regular in size, narrow, generally curved, and occasionally more 

 than half as long as the breadth of the blade; the teeth are often 

 continued on the broadly winged petiole. The lower or occasion- 

 ally solitary stem-leaf is often situated so near the basal rosette 

 that it forms a part of it. The relationship of this form to the 

 rest of the Cerinthoidea here treated is not quite clear to me owing 

 to the insufficient number of specimens at my disposal.
