FLORICULTURAL NOTICES. 
THE COMPOSITE-FLOWERED TRIBE {Composites). 
Senecio cru^ntus. Blood-red Senecio. This species is said to be one of tlie 
parents of all the beautiful hybrid plants, usually called Cinerarias, which now decorate 
our greenhouses so profusely in the spring months. The flowers are smaller and less 
beautiful than those of many of its progeny, and from the repeated impregnations 
between this plant and S. maderensis, it is now rarely met with in its natural 
character. From a most valuable account of the climate of the Canary Islands 
(of which the above plant is a native) by Messrs. Webb and Berthollet, in which 
are included ample particulars respecting the locality it usually inhabits, Dr. Lindley 
deduces that the plants we are accustomed to call hybrid Cinerarias decidedly 
belong to the greenhouse, and should be kept in a moderate temperature, with a 
greater proportion than usual of atmospheric humidity. They would also appear 
to require but a partial exposure to light. Bot. Reg. 7« 
THE CORNEL AG TRIBE {Iridacece). 
Phalocallis pli^mbea. Lead-coloured Phalocallis. In the general appearance 
of the flowers of this beautiful plant, a striking resemblance to the species of 
Marica is perceptible. It has been named by the Hon. and Rev. W. Herbert, in 
whose collection at Spofforth it flowered in the autumn of ] 838. Unfortunately 
it is found to display but one blossom on the summit of its stem, and this ex- 
pands before sunrise, and fades before noon. The flowers are principally of a 
pale lead colour, but their internal structure is both curious and very pleasingly 
marked with yellow and brown. The gentleman above-mentioned presumes that 
it will be found to succeed in an open border with a southern aspect. Bot. Mag.

THE ORCHIS TRIBE {OrchidacecB). 
Maxillaria tenuifolia. Slender-leaved Maxillaria. Two distinct modes of 
growth are observable in the plants constituting the genus Maxillaria; the one 
with prostrate and the other with ascending rhizomata or stems. To the latter 
section belongs the present species, which produces its pseudo-bulbs in a suc- 
cessional series, one above the other. It is less interesting in its habit than many 
other species, but the flowers are peculiarly beautiful ; for, though small, they are 
most liberally blotched with scarlet on a greenish-yellow ground. In its cultiva- 
tion or propagation, not the slightest difficulty is experienced, as it will thrive 
either in a pot filled with the usual materials, or on a block of wood, and may be 
increased to any extent by separating a single bulb from its rhizoma. Mr. Thomas 
Hartweg, who has been sent on a botanical mission to Mexico by the Horticultural 
Society, discovered the species here noticed in the vicinity of Yera Cruz, Mexico, 
and it has flowered in the gardens of the Horticultural Society at Chiswick.
