Siphocampylus. — No less a number than forty-two species of this beautiful genus 
are known, and ten are already in cultivation in this country. Four are shrubs, 
and six herbaceous perennials. All require the heat of the stove, and bear large and 
showy scarlet or violet-coloured flowers, and well deserve to be cultivated in every 
collection. They are very easily managed, growing freely in a mixture of loam, 
peat, and sand ; and cuttings of the shrubby kinds strike root freely in soil under a 
glass, in heat. The herbaceous kinds are increased by division of the roots. 
Tupa. — Sixteen species are known in this country, all very beautiful ; eleven are 
perennial herbaceous plants, of which two require the stove, one the greenhouse ; 
eight need only occasional shelter in severe weather, and may be considered 
frame plants ; and five are shrubs, growing from two to twelve feet high. They 
should be potted in a mixture of peat, loam, and sand, in the same manner as 
Siphocampylus, and, being of rapid growth, must have plenty of root-room. The 
shrubby species are propagated by cuttings of the half-ripened wood planted in pots 
of sand, and placed under a glass in heat, and the herbaceous ones by division : they 
are also raised from seeds, which are sown in pots or pans of light sandy soil, and 
when the young plants are up, and of a sufficient size, the shrubby ones and the 
tender perennial ones may be planted in pots, and the other species, which are more 
hardy, may be transplanted into the open borders in the front of a south wall or other 
sheltered situation. Here they will flower in great perfection. In winter they may 
be either protected with litter or dead leaves, or, which is better, taken up and 
potted, and so protected in a frame, greenhouse, or shed until the following spring. 
Trimeris and Vlamingia are two genera, with the species of which we are 
unacquainted.

GENERA AGREEING WITH DELISSE2E IN SEVERAL IMPORTANT PARTICULARS, 
Centropogon. — This genus contains thirteen species, two of which have been 
some time in this country. They are perennial herbaceous plants of considerable 
beauty, all natives of the tropics, and therefore require the temperature of the stove. 
They are of very easy culture, and deserve a place in every collection. The best 
soil for them is a mixture of peat, loam, and sand in equal proportions. In potting, 
give abundance of drainage, otherwise, as they require a large supply of water when 
in full growth, it would stagnate, and injure if not destroy the roots. When the 
growing and flowering season is over, gradually diminish the quantity of water, and 
finally set them in a cool and airy part of the house to winter, and keep them some- 
what dry. Increase is effected both by division of the roots and by cuttings planted
