ALFRED REHDEK. 



SUCCISA (succise, praemorse; cut off at the lower 

 end, referring to the root). Dipsacese. Three or 4 herbs, 

 by some authorities incl. in Scabiosa, of the Medit. 

 region to Trop. Afr., marked by the soft or herbaceous 

 scales or palea (involucels) subtending the florets in 

 the head, and by other technical characters. To this 

 genus or group belongs the "teufelsabbiss" of the Ger- 

 mans. The plants are little known in cult., but S. 

 australis, Mert., is listed abroad among outdoor per- 

 ennials. Nearly or quite glabrous: Ivs. ovate-elongate 

 and acuminate, entire, the lower ones somewhat auric- 

 ulate: heads ovate, with lilac- violet or ochroleucous fls.; 

 scales of involucre in 2 series. S. pratensis, Moench. 

 (Scabiosa Succisa, Linn.), may be cult.: root praemorse 

 (as if cut off) : radical Ivs. ovate-lanceolate, acuminate 

 and entire, the cauline ones connate : scales of involucre 

 in 2 or 3 series.
