THE APPROACH OF SPRING.

Butea frondosa and superba are also plants of great splendour, with scarlet, pea. 
shaped flowers, not unlike those of Erythrina ; no stove collection should be without 
them. They require to be started into growth this month, by giving an increase of 
temperature, and a corresponding humid atmosphere. With the exception of shade, 
which these plants scarcely require, the treatment of Brownea grandiceps and race- 
mosa will exactly suit them. 
Brexia Madagascar ensis. — Almost all failures in growing this plant to perfection 
may be traced to giving it too little pot-room. 
BryophyUum calycinum. — A succulent found in almost every old collection, of 
easy growth, but rarely seen in flower. Plunge the pot containing it up to the rim 
in a hot-bed, and give little or no water. If there is a good heat kept up in the 
bed, it will very soon show abundance of flowers. Then remove it to any part of the 
stove you deem best, and it will continue blooming for a long time. 
Calyptranthes. — Although the species of this genus were introduced many years 
ago to our collections, they are now scarcely to be found throughout the country. The 
chief difficulty in their cultivation has been a want of knowing the mode of increas- 
ing them. Cuttings of the ripe wood should always be put in at the end of 
September, and stand through the winter in a dry, cool place. During the present 
month, introduce them into a strong moist heat, plunging the pots up to the rim 
and they will strike with the greatest freedom. This is also a proper time to make 
layers ; the parent plant must be introduced into a house or pit, where the pots 
containing the layers can be plunged in a hot-bed where there is a brisk heat, and 
the success will be rapid and certain. 
Ixora coccinea, crocata, Sc. — Although the different species of this lovely genus 
have been so often noticed before in the volumes of this work, it may not be amiss 
again to mention, that one of the chief reasons why these plants suffer so often during 
the winter, is, their being placed too near a flue, or other dry heat, in which situation 
they require to be often watered, and this exposing them to so many alternations of 
drought and moisture, finally injures the roots, or perhaps kills the plant. The 
best situation during the season of repose is a rather cool and shady part of the stove, 
where they will seldom require watering, and where the soil can be allowed to become 
partially dry. This is the month to set them growing; the same treatment as 
recommended for Brownea grandiceps, will suit them well. Plunging the pots 
in a hot-bed is sometimes resorted to, but always with bad success ; the roots are too 
susceptible to admit of this with impunity. 
Of greenhouse species we may notice Angophora cordifolia and lanceolata, two 
very handsome species, both shy of flowering until they arrive at a large size. If 
they are now subjected to stove heat for a month or six weeks, they will form flower 
buds ; they may afterwards be removed to their former quarters in the greenhouse. 
Astelma eximium is a very beautiful flowering plant, the leaves of which are
