This superb Erythrina was communicated to the author by A. B. Lambert,
esq., with whom it flowered in the month of November, for the first time
in this kingdom. It is at present treated as a hot-house plant, but Mr.
Lambert informs us that it is perfectly hardy, and strikes so freely
that, although at present it is a nondescript and very rare plant, it
will, doubtless, soon make its appearance in most collections: its
splendid flowers and easy culture will soon recommend it into general
notice. There are but five species of this genus yet known; the present
subject will therefore be a valuable addition to the number. The falling
off of the leaves is its only defect, which we have no doubt but a
hardier mode of treatment will remove. It is supposed to be a native of
South America.
