Cattleya Mossi^. Mrs. Moss's Superb Cattleya. Unquestionably one of 
the most magnificent of all vegetable productions, surpassing even C. labiata in the 
size of its flowers, and the exquisite richness of the markings of its labellum ; added 
to which, its fragrance is said to be most powerful and agreeable. We give the 
following dimensions as stated by Sir W. J. Hooker : — " The diameter of this 
splendid flower is, from the tip of the upper sepal to the tip of the labellum, seven 
inches and a half ; from tip to tip of the two opposite petals eight inches and a 
half ! each petal being a little more than four inches long, and two inches and a 
half in breadth ; twenty-four inches in the circumference of the entire blossom ! " 
It is named after Mrs. Moss, of Otterspool, near Liverpool, in whose collection it 
first produced its gigantic flowers, and to which it was introduced from La Guayra, 
through the medium of George Green, Esq., of Liverpool, in September 1836. It 
differs from C. lahiata^ to which its flowers bear a great resemblance, " by its 
elongated, branching stem, bearing many deeply sulcated pseudo-bulbs, by the 
much broader sepals and petals, which latter are unguiculated at the base, and by 
the colour, and markings and size of the lamina of the labellum." Bot. Mag. 3669. 
NOTICES OF NEW AND RARE PLANTS 
IN FLOWER IN THE FEINCIPAL NURSERIES IN THE VICINITY OF LONDON. 
Messrs. Henderson's, Pine Apple Place. Eutoca Wrangeliana. This pretty 
annual is now flowering most abundantly in the open ground at the nursery of the 
gentlemen above named, and is well calculated for planting in beds or masses in 
the flower-garden, as it makes a most brilliant display when thus treated. Poten- 
tilla Tongui. This is a neat and very interesting little plant, of trailing habits, 
and producing a great number of its showy orange and brown-coloured blossoms ; 
it is a valuable species for planting on rock- work, mounds, or any elevated and 
conspicuous situation. Seckim SieholdiL A Japan species of some interest, and 
apparently perfectly hardy ; its dense clusters of small pink blossoms, with which 
the plant is most profusely furnished, are nov/ exhibiting themselves at this nursery, 
and remain expanded a considerable time. 
Mr. Knight's, Chelsea. Gesneria rupestris. This elegant little plant, of 
which a figure has been given at page 53 of the present volume of this Magazine, 
is flowering in great perfection in the stove of this gentleman, and is one of the 
most delightful objects which have yet been cultivated in our stoves. Aristolochia 
kgperborea. We noticed this species in our July number, and there stated that it 
was destitute of a specific name. We now give the one under which Mr. Knight 
received it, and add, that it is again flowering much more abundantly in the 
collection of that gentleman. It is a very handsome species, and possesses but 
little of the offensive odour for which its allies are remarkable. Ferraria azurea. 
An extremely beautiful, and we believe new, species of this interesting genus of
