“ M. Kunth, who first established the genus, appears to
have been acquainted with only one species, namely l.flo r i-
hiinda, which he describes as herbaceous, but it is most probably
shrubby, like the other three species which I have
added to the genus. The species are all natives of Mexico,
from which country the subject of the present article was
introduced in 1827, by Robert Barclay, Esq. in whose collection
it flowered last Autumn for the first time. The plant
is decidedly shrubby, and merits a place in every collection,
from the abundance of its snowy heads of flowers, which
have a very fragrant smell, resembling that of honey. The
Melampodeæ constitute a very distinct group of the Helian-
thece,^ containing, besides the present genus, Melampddium,
Poly'nmia, U'nxia, Joegèrïa, and Montanda. The capitulum
of Eriocoma is really simple, as is proved by the expansion
of the florets being from circumference to centre, a though
from the defective nature of the involucrum, and the total
separation of the florets by the enlarged persistent paleæ, one
would be apt to conclude that it was compound. This genus
agrees with Echinops in the form and consistence of its florets,
and also in the anthers being furnished with two teeth
at their base .”
For the above account of the present interesting genus,
we are indebted to Mr. David Don, who, from the richness
of Mr. Lambert’s extensive Herbarium, has been enabled to
add three more species to the genus, besides the present, one
only being before described. In Mr. Barclay’s collection it
was planted by the side of a wall in the Flower Garden,
where it produced its numerous panicles of fragrant flowers
last September and October; it needs the protection of a mat
in severe frosty weather in Winter, by which means the
greater part of the plants from Mexico, and the temperate
parts of South America, will succeed very well ; by this
means Escallonia Jloribûnda has stood well with us this severe
Winter, and is now growing very fine.
The generic name is derived from tyiov, wool, and Koga,
a lock of hair, from the numerous woolly hairs, with which
the paleæ are covered.
1. Back view of the Involucrum. 2. One of the scales from the Receptacle, that
