scarcely acute, longitudinally striated, smooth and glossy,
spreading, or a little reflexed : inner series 8 to 10-part-
ed, the segments spreading, and supporting the rays,
oblong, obtuse, membranaceous, w ith a fleshy base. Re-
cefiacle paleaceous, the chaff similar to the segments of
the inner series of the involucrum. Rays 8 to 10, spreading,
sterile, or producing no style or stigmas. Florets o f
the disk fertile, tubular, 5-toothed; teeth short, erect.
Namens 5 : jilaments distinct, smooth : anthers connected
into a tube. % /e smooth, exserted. 2-parted,
the segments firnbriate, spreading. AkeniaovseedWnear,
flat, pubescent, in which it differs from G. Cervantèsii
which is spathulate.
This very distinct species was pointed out to us this
Autumn by Don Mariano Lagasca, at the Nursery of
Messrs. Whitley, Brames, and Milne, at Fulham, as his
Uahha crocata; it is readily distinguished from all the
other species by its hollow fistulous stem, which is
scarcely branched, and by which it is readily distinguish-
ed from G, coccínea and G. Cervanthsii, and is nearer re-
lated to G. ròsea, (the Dáhlia ròsea of Cavanilles,) a species
also with bipinnate leaves, and very different from
the rosea of the gardens, which is nothing but a variety
of G. variáhilis : we have already, in the “ Florist s Guide,”
given our reason for adopting Willdenow’s name of
Geo R G iN A in preference to D a h l i a of Cavanilles, there
being a genus from the Cape named D a h l i a before by
Thunberg, and Willdenow’s name is adopted by Decandolle,
Kunth, and most of the continental Botanists, and
it IS most proper, as Thunberg’s genus has the right of
priority.
The present species was raised at Madrid, in the year 1804, from
Mexican seeds sent by D. Sesse, according to Lagasca; it requires the
same treatment as the more common sorts, to be planted in the open
borders in April, to be taken up as soon as the frost sets in, and to
be kept dry and out of the reach of frost through the Winter- a poor
sandy sod suits it best, as in that it will grow dwarfer, and produce
more flowers; it will require to be well secured by being tied up to a
strong stake, as its stems are easily broken down by the wind; it is
readily increased by dividing at the root, or by seeds.
The genus was named by Willdenow, in compliment to J. G. Georgi,
a Russian Botanist, and autlior of some valuable works on the botany
ot Russia. Bahliawas in compliment to A. Dahl, a Swedish Botanist.
