LIST OF NEW PLANTS. 
Pentandria Monogynia — Cinchonacece. 
Rondeletia longiflora. A native of Brazil, imported by 
Messrs. Veitch, of Exeter. R. Odorata and R. Speciosa are 
well-known inhabitants of our stoves, the present species re¬ 
sembles in some degree R. Odorata in its inflorescens, being pro¬ 
duced in clusters : “ The individual flowers have a tube an inch 
and a half in length; the colour is a blueish lavender, very 
deep and exceedingly attractive ; there is also a trifling odour 
when the flowers are perfect.” In the cultivation of this plant 
the most important particular to be observed is the frequent stop¬ 
ping of the young shoots, to prevent the naked appearance so fre¬ 
quently observable in other species of this genus; in other respects 
it agrees with its congeners. It flowered for the first time in the 
collection of the nurseryman above named, in July of the present 
year. — Pax. Mag. Bot. 
Polygamia Moncecia — Leguminosce. 
Acacia biflora. This is a pretty greenhouse plant, of the ca¬ 
pitate division of the genus acacia , the flowers being produced 
plentifully in small round heads. It was originally introduced 
to this country in 1803, but was subsequently lost and was again 
made known by Messrs. Low & Co., of Clapton, who imported 
it about two years back. The plant rises to about three feet in 
height, of tolerably compact growth, and produces its blossoms 
for the most part in pairs, as the special name implies. It aflects 
the usual treatment for this class of plants, with the addition of 
a little timely pruning while young.— Pax. Mag. Bot . 
Icosandria, Di-pentagynia— -Ficiodecc. 
Mesembryanthemum tricolor. This beautiful little and once 
favorite tender annual has here received a notice calculated to 
bring it once more to its proper station among the summer or¬ 
naments of our greenhouses. The whole family are exceedingly 
interesting, and this species preeminently so. It was introduced 
so far back as 1795, but has since been much neglected. It re¬ 
quires the treatment usual for tender annuals, observing to sup¬ 
ply it but moderately with water while young. The flowers are
