FLORICULTURAL NOTICES. 
NEW AND RARE PLANTS FIGURED IN THE LEADING BOTANICAL PERIODICALS FOR 
SEPTEMBER, 
Allium cyER^rLEUM. An exceedingly interesting species of Allium, with leaves 
and inflorescence like those of the leek, and beautiful bright blue flowers, the colour 
of which varies a little in intensity, though it is usually azure. It was " originally 
found by Pallas in abundance upon the salt plains of Asiatic Russia, near the 
Irtisch river ; afterv^ards by Ledebour, on the Altai mountains, near the fortress of 
Buchtarminsk, flowering in May and June." From seeds received by the Horti- 
cultural Society, through Dr. Fischer, in 1834, it has been freely germinated. In 
our gardens it forms a neat bulbous plant, of about eighteen inches in height, 
perfectly hardy, and requiring a moderately rich soil. Offsets from the old roots 
will afford a means of propagation, and the seeds may likewise be sow^n in pans as 
soon as they are ripe, treating them as other bulbous plants, and not removing the 
young stock till the second year after sowing. Bot. Reg. 51. 
Catasetum integerrimum. Mr. Skinner sent this fine species from Guatemala 
to the late Duke of Bedford at Woburn Abbey, where it appears lately to have 
produced its flowers. It is very distinct, " having a lip with the mouth considerably 
contracted, and quite entire." The leaves are particularly large, being more than 
four inches broad, while the blossoms are likewise of great dimensions, and exhale 
a rather heavy smelL There are two varieties, differing slightly in the colour of 
their flowers ; the one having greenish sepals and petals, much tinged with purple, 
and spotted with the same hue, the other being more decidedly green, spotted with 
reddish-purple, and possessing a smaller labellum, less obtuse at the base ; the lips 
of both are yellow internally, and very richly blotched. Bot. Mag, 3823. 
Cereus sPECiosfssiMUS ; hybriduSo a splendid hybrid production, raised by 
Mr. Mallison, gardener to Sir Samuel Scott, from seed of C. speciosissimus fertilized 
by C.flagelliformis, and partaking largely of the character of each. The stems are 
much more slender than those of the female parent, and approximate to the rounded 
form of the male, with, however, fewer angular ribs. The flowers are not so 
gorgeous as those of C. speciosissimus, but larger than those produced by C.Jlagel- 
liformis, and of the same deep crimson colour. It is known in gardens by the name 
of C. Mallisoni, and is a most valuable object. Bot. Mag. 3822. 
Clematis montAna. Without any claims to actual novelty, since it has been 
in the country several years, it may be assumed that the merits of this worthy 
plant are not yet sufficiently appreciated. " According to Dr. Royle, Clematis 
grata from its fragrance, and C. montana from the showy nature of its garlands of 
numerous white rose-like flowers, are the most desirable of the Himalayan species 
of this charming genus as ornamental plants. Certainly nothing can well be more
