XXIII. On the Cultivation of the Amaryllis Saniiensis, or 

 Guernsey Lily. By Thomas Andrew Knight, Esq. 

 F. R. S., $c. President. 



Read December 20, 1825. 



So many splendid species and varieties of Crinum, and other 

 plants of the Liliaceous tribe, have within a few years been 

 introduced into our gardens, that the culture of the Amaryllis 

 Sarniensis, or Guernsey Lily, notwithstanding the unrivalled 

 splendour of its blossoms when closely inspected, has to some 

 extent ceased to interest the modern Gardener. I should 

 consequently think the matter of my present communication 

 scarcely worth sending to the Horticultural Society, if I were 

 not perfectly confident that the same mode of culture is 

 applicable to bulbous roots of every kind which do not flower 

 freely (exclusive of those which grow in water), and with 

 but little variation to plants of every kind. Wishing, how- 

 ever, at the present time, to confine myself to very narrow 

 limits, I shall simply relate the experiments which 1 have 

 made upon the Guernsey Lily, with the conclusions which I 

 have drawn from the result of those experiments ; and my 

 narrative will I think be most plain and intelligible, if I con- 

 fine it to treatment through successive seasons, of a single 

 root of that plant.
