of the bulbs grow to an enormous size, and all of them, while 

 growing, require a liberal supply of water; but when dor- 

 mant it must be wholly withheld, and they should have large 

 pots, to make them grow and flower in peifection. B. mid- 

 tlflbra, flowers scarlet and green ; the leaves lie on the sur- 

 face of the pot. B. laticbma, flowers pale purple. B. Jose- 

 phine has splendid rose-coloured flowers, and the most admired 

 species of the genus; the foliage spreading, half-erect, and 

 glaucous ; flowers numerous, and in large umbels, on a stem 

 two feet high, blooming successively : there is a variety that 

 has striped flowers. 



Several other species have been given to different genera. 

 B. falcdta is now Ammdcharis falcdta ; B. margindta, now 

 Imhdfia ; and B. cilidris is now Buphdne cilidris. They all 

 flower in umbels, on stems from six inches to two feet ; flowers 

 lily-like, with six petals. (Soil No. 12.) 



Burchellias, two species. B. capensis is a beautiful dwarf 

 evergreen shrub, with tubular orange-coloured flowers, in large 

 terminal clusters; when well treated, grows and flowers freely, 

 and highly deserving of attention. B. parviflbra differs from 

 the above in the flowers being smaller and paler, and the 

 foliage more pointed. (Soil No. 10.)

Calceolaria. This genus of plants has undergone a com- 

 plete revolution. Within these few years, hundreds of superb 

 hybrid varieties have been brought to notice, many of them 

 truly splendid. With us the herbaceous kinds are very deli- 

 cate during summer; they are generally all cut off by our 

 intense heat, or severe droughts. The shrubby varieties 

 appear to withstand the vicissitudes of our climate better, 

 though, as yet, we confess we are not even altogether success- 

 ful in their summer culture. However, a few of them have 

 done well, and are C. angustifblia, bright yellow, and in great 

 profusion; C. Daniel 0' Connell, brown mottled; C. Sultan, 

 crimson purple ; C. Jujnter, brown and yellow ; C. marjo- 

 ridna superba, nearly scarlet; C. smhthii, red and yellow; C. 

 ignea, bright crimson ; C. meteor, dark crimson; C. Vulcan, 

 dark red; C. maculata, superbly marked with red or crimson. 

 There are many others of very great merit of the shrubby 

 kinds cultivated in Europe, such as whites of different shades, 

 dark crimsons, with white capes, and others blending into 

 almost every description if colour and character. Any quau-
