tected from the powerful rays of the sun. Drain the pots 
well. (Soil Xo. 6.) 
Bruasvigias are all large bulbs from the Cape of Good 
Hope, and will keep in the green-house during winter, but 
are better where they can obtain a situation in the hot-house. 
It is a splendid genus, containing about ten species. Some 
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 perfection. B. mid- 
ti flora, flowers scarlet and green ; the leaves lay on the sur- 
face of the pot. B. laticbma, flowers pale purple. B. Jose- 
phince has splendid rose-coloured flowers, and the most ad- 
mired 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. falcata is now Ammdcharis falcata ; B. margindta, now 
Imhdfia ; and B. cilidris is now Buphone cilidris. They all 
flower in umbels, on stems from six inches to two feet ; flow- 
ers 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. parviflora. differs from 
the above in the flowers being smaller and paler, and the 
foliage more pointed. (Soil Xo. 10.)

Calceolaria. This genus of plants has undergone a com- 
plete revolution. Within these few years, hundreds of su- 
perb hybrid varieties have been brought to notice, many of 
them truly splendid. With us the herbaceous kinds are very 
delicate duriDg 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. angustlfblia, bright yellow, and in 
great profusion ; C. Jupiter, brown and yellow; C. marjo- 
ria.ua superha, nearly scarlet; C. sm\thii,Ted and yellow; C. 
ignea, bright crimson ; C. meteor, dark crimson ; C. Vulcan,
