and bears at the summit a compact panicle of handsome crimson 
flowers, covered with a delicate bloom, and orange-coloured in¬ 
side. It is a pretty greenhouse, half-shrubby plant, and grows 
freely in a light mixture of sandy loam with leaf-mould and 
plenty of silver sand. It is easily increased by the leaves, 
rises from one to two feet high, and flowers freely from Novem¬ 
ber to April, that is to say, throughout the winter.”— Bot. Beg.

CactacEtE . —Icosandria Monogynia. 
Echinocactus cinnabarinus (Hooker). A neat species in re¬ 
gard to the form and arrangement of its tubercles, and very 
striking when in flower, from the numerous rich cinnabar- 
coloured petals, which spread to a diameter of three inches. The 
species is among the many rare ones from Bolivia purchased for 
the Royal Gardens from Mr. Bridges. It flowers in a cool green¬ 
house in July. Our specimens grow solitary, and are globose, 
bat depressed and umbilicated in the centre, six to seven inches 
in diameter, and three or four inches in height. The surface is 
formed of copious dark green mammillce or tubercles, closely 
packed and arranged in spiral oblique lines; they are four-sided 
at their base, and dilated at the back into a deep, vertical, rather 
short keel, on the top of which the areola is situated; this 
areola is small, woolly, and bears a cluster of about twelve, pale 
brown, narrow, subulate or acicular, but rather strong aculei; 
those of the circumference are nearly equal in length, and form 
a circle J to f of an inch long; the central one 1 is longer and 
stronger than the rest, all slightly curved. The lower sepals of 
the calyx are short and acute, the superior one and the petals are 
spathulate, and alike of a rich cinnabar colour.— Bot. Mag. 4326.

Chirita Walkerice (Gardner). Mrs. General Walker detected 
this fine species of Chirita in Ceylon in 1830. It remained for 
Mr. Gardner, the able director of the Botanic Garden, Peradenia, 
Ceylon, to send the seeds to us in 1845, and to establish it as a 
new species with a full and accurate character. In 1846 our 
plants bloomed, and proved the species to be well worthy of a 
place in every collection, from the beauty of the flowers and their 
continuing long in perfection. Indeed there is scarcely a month
