Cult. Gouffeia only requires to be sown on rock-work, 

 or in the open border, where it will flower and ripen seed freely, 

 but being a weed-looking plant it will be scarcely worth culti- 

 vating, except in botanical gardens.

Perennial Buffonia. Fl. June, Jul. Clt. 1817. Pl.|to|ft. 



Cult. Both the perennial and annual species of this genus 

 can only be encreased by seeds ; they only require to be sown 

 in the open border or on rock-work, but being weedy looking 

 plants, they are hardly worth cultivating, except in botanical 

 gardens or in those of the curious. A dry sandy soil suits them 

 best. A plant or two of the perennial species should be kept 

 in pots, so that they may be sheltered by a frame during winter, 

 as they are otherwise apt to damp off in that season. 



XVII. SAGI'NA (sagina, in Latin, signifies fatness ; accord- 

 ing to Linnaeus it is so called for its qualities in fattening sheep).
