or by a kind of bulbiferous seed which they occasionally ripen, par?- 
ticularly the Botany Bay lily (C. pedunculatum) when they are shy 
in throwing up suckers ; cutting down near to the root will cause 
them to produce abundance, indeed, if the root gets wounded by any 
means, it in general produces the same effect, and Mr. Sweet in his 
"Botanical Cultivator" partly recommends the practice, , they are.alj 
of very easy culture. i'J Jidcifni aasfb (;'fto gnillfil ion) Inajeiaisq

species of this genus, require only the heat of the green-house, and 
only that duiing the colder months of the year ; tliose who have 
any other convenience, may grow them to perfection in a frame, by 
potting the bulbs very shallow in light sandy loam, mixed with equal 
parts of peat earth, or leaf-mould, and watering very sparingly when 
'not in a growing state ; they however must be allowed plenty during 
4jheir time of flowering, and if fresh potted just before they begin to 
grow, they will in general flower very freely, and occasionaMy ripen

siderable size, And do not thrive if cramped in small pots, indeed 
they blow very well if planted in the open borders in spring, provi-
