NEW AND RARE PLANTS IN FLOWER.

greenhouse of this gentleman, which is of a stronger and more luxuriant habit than 
most others of the same character, with which we are acquainted ; but its distin- 
guishing feature is that the spots in the flowers, (which otherwise resemble M. 
Smithii, and others,) are not of one uniform colour, but are mottled and blotched 
in a most curious and interesting manner. It is certainly a most ornamental 
plant, and highly worthy of a place in any collection where variety is sought for 
or desired. 
Messrs. Rollisons', Tooting. Maxillaria tenuifolia. This is a new and 
exceedingly pretty species of the extensive genus above mentioned, and derives its 
name from its small and narrow foliage. The flowers are small, but singularly 
beautiful, combining in them a striking variety of rich and showy colours. It is a 
plant of considerable merit, and should be in every collection of orchidacese. In 
the excellent collection of these gentlemen a new and curious species of Pleurothalis 
is now in flower, the blossoms of which, though small, are interesting and pretty, 
and are produced in racemes which spring from the centre of the leaves. It is 
valuable only to lovers of novelty. Messrs. Rollison also possess a new species of 
Dendrobium, now coming into flower, which they have recently imported from 
Ceylon ; the flowers appear to resemble D. cucullatum externally, but they were 
not expanded when we saw them, and the most remarkable feature in the plant is 
that the pseuclo bulbs are nearly an inch in diameter at the base, from which they 
gradually become elongated into slender stems, from one to two feet in height, r and 
on these latter the young shoots and flowers are produced. It will probably prove 
valuable, and will doubtless be new. Helichrysum macranthum. This is a very 
elegant new species of this interesting genus, the flowers of which are of a delicate, 
pale rose-colour, and are very interesting and ornamental. It is now in flower in 
the greenhouse of this nursery. 
Mr. Young's, Epsom. Pkilibertia grandiflora. This interesting climbing 
greenhouse plant, which is yet extremely rare, is now flowering profusely at this 
nursery ; the flowers are of a light stone-coloured ground, and are prettily streaked 
and marked with purple. The plant produces three or four flowers from the axil 
of each leaf, and it appears to flower in very abundant succession; on which 
account it will prove a valuable accession to our present stock of greenhouse 
climbing plants. Malm Towardii. This is a handsome new species of Malm, 
producing a large spike of its showy blossoms when not more than one foot high. 
It is a half-hardy species, and is now in flower in the open ground, at the above 
nursery, though it will doubtless require the protection of a greenhouse or frame 
in the winter. Platystemon Californicum. This pretty annual is now producing 
its elegant pale sulphur-coloured blossoms in the nursery of this gentleman, and 
forms a most interesting feature among other hardy annuals. Bartonia aurea, 
another plant of annual duration, and equally rare and interesting, is also exhibiting 
its bright orange-coloured flowers most profusely at this nursery, and is highly 
worthy of a place in every collection.
