Contrary to what we observe in most of the plants of this genus, the
present very rare and no less beautiful species of Flax forms (if not a
tree, as its name imports) a shrub of the height of several feet, which
begins to flower in the green-house in March, and continues to be more
or less covered with blossoms to the close of the summer.

It is a native of the Levant, from whence it was introduced to this
country in the year 1788, with a profusion of other vegetables, by JOHN
SIBTHORP, M. D. the present celebrated Professor of Botany in the
University of Oxford; who, for the laudable purpose of promoting the
science in which he is so eminent, and of enriching the Oxford
collection, already rendered most respectable by his unwearied labours,
meditates, as we are informed, a second journey into Greece.

Hitherto this plant has produced no seeds in this country, and it is
with difficulty increased by cuttings.

Our figure was drawn from a plant which flowered in the spring with
Messrs. GRIMWOOD and Co. Kensington.

Of this genus, two species only have as yet been discovered, the one a
native of Great-Britain, the other here figured the produce of Siberia
and Cappadocia, both hardy, perennial, herbaceous plants; the latter,
more particularly, from the bright orange colour of its flowers, held in
high estimation as an ornamental plant, and flowering in May and June.
This species, as yet rare in this country, is usually propagated by
parting its roots in autumn; it may also be raised from seeds, which
ripen frequently on strong healthy plants: to succeed in its
cultivation, we should plant it in a composition of loam and bog earth,
and place it in a north
