yellow, and it is a native of the South of Europe, so that 

 it is tolerably hardy here, but looks remarkably well in the 

 greenhouse. C, {Agatlicea coelestis) amelloides is sometimes 

 called the Cape Aster ; it is a favourite flower in the green- 

 house, with bright blue flowers, appearing in February and 

 continuing for some months. The plants appear to flourish 

 the best when they are kept in a cold frame, if there is no 

 frost, till they show flower, and then removed to the green- 

 house. Cuttings from them root readily. 



ACROLINIUM. 



Gen. Char. (Syngenesia JSqualis.) Involucre imbricated ; recep- 

 tacle conical ; corollas tubular, five-toothed ; pappus lasting. 



This is a genus of Swan River plants, quite worthy of 

 introduction into the greenhouse. A. roseum is a very beau- 

 tiful annual, the flower being often two inches across, and 

 rose-coloured, with a bright yellow centre, the involucre 

 brownish or olive-green, tinged with dark red. It flowers 

 very freely, and proves to be half-hardy.
