 terminal, 2 together, gradually thickened toward the apex, remotely 

 bracteate. Gapitula solitary, oblong-campanulate, 1 in. long, not 

 calyculate. Involucral bracts 8-9, linear, acute or pointed, |-J in. 

 long. Florets about 30, all tubular; corolla lilac or rose-coloured.

Ascherson, I.e., unites the Abyssinian plant with Forskal's Arabian species, Ca- 

 calia semperviva ; the latter, however, is described as heads 60-flowered. He also 

 unites N. grandiflora, DC, i.e., Cacalia grandijlora. Wall., an East Indian species.

 and homogamous. Involucre from hemispherical to cylindrical ;
