NEW AND RARE PLANTS IN FLOWER.

and highly beautiful tribe of plants, as, in short, a collection of succulent plants 
seems almost an indispensable requisite to give to a good place its proper character 
and finish ; for from the great and singular variety that these plants assume they 
cannot fail to excite the interest and admiration of the cultivator at all seasons of 
the year. Mr. Low has especially some very fine specimens of that remarkable plant 
Cereus senilis, or, as it is commonly called, " The Old-man Cactus." 
Messrs. Rollison's, Tooting. Maxillaria Rollisonii. This is, we believe, 
a new species of Maxillaria, named in honour of Messrs. Rollison ; it assimilates 
very much in habit to M. stapelioides ; the flowers are small, cream-coloured, and 
beautifully spotted with red ; it makes a very interesting addition to the species of 
this genus previously known, and is worthy of a place in every collection. Onci- 
dium leucochilum. This beautiful species is again flowering most profusely at the 
above nursery, and recommends itself to the notice of every lover of Orchidese. 
Cistus speciosus, an old but highly beautiful stove plant, is now flowering in great 
perfection at the above nursery, and is highly worthy of cultivation. 
Mr. Young's, Epsom. Pentstemon gentianoides. This beautiful species oi 
Pentstemon is now producing its elegant blossoms in great perfection at this nur- 
sery ; the flowers are of a fine purple colour externally, while the inside of the 
mouth of the corolla is white, beautifully spotted with purple ; the foliage, though 
not so large as that of P. Murryanus, is of a deeper green, and very handsome, 
and the plant being a very abundant flowerer, is truly interesting and valuable, and 
no collection should be without it. Aconitum Chinense. This is a new species of 
this extensive genus, and, we think, is the finest with which we are acquainted ; 
the immense size and great beauty of its flowers, its remarkably fine foliage, and 
the habit it has of producing a fresh spike of flowers at the axil of every leaf, ren- 
der, it a most valuable addition to our stock of hardy herbaceous plants ; no collec- 
tion, however limited, should be destitute of it, as it is well adapted for any flower- 
garden purposes. Liatris borealis. This elegant new species of Liatris is now 
beautifully in flower at the above nursery ; the flowers are produced in clusters, 
and are of a pretty pink colour ; the plant is about two feet high, and when in 
flower has a very neat and interesting appearance. Dianthus superbus, Jlore pleno. 
This is a most splendid variety, and is, we believe, new ; the flowers are large, of 
the richest possible crimson colour, and are produced in great abundance, and a 
more beautiful object when in flower cannot well be imagined ; it is now adorning 
the flower borders of the above nursery, and should be in the possession of every 
person who possesses a flower garden. Mr. Young has likewise a quantity of splen- 
did specimens of Pentstemon Murrayanus now in flower, and we have nowhere seen 
such an excellent stock of this much admired species, as well as other beautiful 
species of this genus, as at this nursery. There is also a remarkably fine specimen 
of Clematis Sieboldi now flowering in a high state of perfection.
