scape does not bear more than one flower, instead of several, but of this I cannot 
so well judge." This species was imported by G. Barker, Esq., of Birmingham, 
with whom it flowered in November 1838. It was originally found by Count 
Karwinski, near Oaxaca, and is now supposed to be frequent in collections. Like 
most of its allies, it is a very beautiful plant, and requires a less degree of mois- 
ture and temperature than many other orchidacea3. Bot. Reg. 2(3. 
THE ARUM TRIBE {Aroidea;). 
Caladium petiolatum. The remarkable structure of the plants of this tribe 
is in all cases interesting, and in the present species, combined with the striking 
tints, is peculiarly so. It has a long and curiously mottled stem, or petiole, sur- 
mounted by a pair of large pinnate leaves ; and from its base the flower-scape 
arises. This latter generally attains the heiglit of one foot, and on its summit 
the flower appears, enveloped in a large, rich purple, and very ornamental spathe. 
Tubers were first discovered by Mr. Boultbee jun., in the island of Fernando Po ; 
these were transmitted to Joseph Boultbee, Esq., Springfield, Knowle, Birming- 
ham, in whose stove they flow^ered in 1832 ; since which period it has blossomed 
in the Glasgow Botanic Garden. It usually flowers in June, and thrives best 
in a rich loamy soil, with a plenteous supply of water while growing. Bot. Mag.

NEW, RARE, OR INTERESTING PLANTS IN FLOWER IN THE PRINCIPAL 
SUBURBAN NURSERIES. 
Bor5nia crenulata. — A very pretty species, slightly inferior to B. serrulata, 
from which it is distinguished by its shorter, darker green, and crenated foliage, 
and deeper coloured flowers ; these latter being also axillary and solitary, (instead 
of in terminal clusters), and much more expansive. It is figured in the fourth volume 
of this Magazine, and is now flowering most abundantly in the greenhouse of 
Messrs. Loddiges, Hackney. By its less straggling habit, and tlie stems being- 
well covered with leaves, it is rendered very nearly equal to B. scrrtdata. 
BuRLiNGTONiA VENi^STA. — Mossrs. Loddigos possess a handsome specimen of 
this extremely elegant and little orchidaceous plant, in flower at the present time. 
It grows most successfully on a piece of wood, producing its long, channelled, and 
deep green foliage in a similar direction on either side of the stem, this being occa- 
sionally interspersed with small, attenuated roots. The flowers are protruded in 
half-pendent racemes ; they are numerous, comparatively large, and pure white, 
with a slight tinge of yellow down the centre. Its native country is Brazil. 
Chorizema varia.— -Decidedly the finest species of this highly interesting- 
genus yet introduced. It has recently blossomed in great perfection at the nursery 
of Mr. Hally, Blackheath. In the size and brilliant colours of its flowers, it is 
certainly surpassed by no other species ; while the leaves and habit are of a 
remarkably ornamental character. Growing with great rapidity and vigour, it
