Generic Charactkb. — Involucre with many imbricated scales ; 
receptacle honey-combed and chaffy. Florets of the ray feminine and 
ligulate ; those of the disk hermaphrodite and tubular. Anthers mutic 
Description, &c. — The two species which compose this genus were separated from Doronicum by the late 
Professor Don, on account of their honeycombed receptacle, double pappus, and hornless anthers. Professor Don 
called this genus Diplocoma, from two Greek words, signifying a double lock of hair, in allusion to the seeds 
being furnished with a double row of pappus ; but Professor De CandoUe has changed its name to Heterotheca, 
which signifies a double sheath, though we are not told how it is applied.

Description, &c. — A hardy perennial, growing from a foot to eighteen inches high, " branched, and 
terminating by a loose corymb of flowers, striated with numerous longitudinal stripes, some of which are tinged 
with purple, and densely clothed with spreading hairs that are unequal in length." The leaves are hairy on both 
sides, and fringed at the margin ; some of them are fiddle-shaped, and others tapering gradually to the point : 
the stem leaves are sessile, and stem-clasping a little at the base ; but the radical leaves are on tolerably long 
petioles. The whole plant is covered with hair. The species is a native of Mexico, whence it was introduced in 
I827. Tlie plants flower during the summer, and ripen abundance of seed. The stems die down to the ground 
towards the latter end of autumn, and the roots should be slightly protected during very severe frosts. 
GENUS XXIX. 
ARCTOTIS, Lin. THE ARCTOTIS. 
Lin. Sgst. SYNGENESIA POLYGAMIA NECESSARIA. 
Generic Character. — Flowers radiate. Receptacle honeycombed, bristly. Seeds doubly furrowed on the back ; pappus chaffy. Involucre 
imbricate ; scales rough at the margin. 
Description, &c. — The species belonging to this genus are all somewhat tender, though they will flower well 
in the open air if slightly protected through the winter. They are all remarkable for the size and beauty of 
their flowers, which are frequently tinged with a kind of reddish orange, which harmonises admirably with green. 
In situations where it is not convenient to protect the plant during winter, cuttings should be made in tlie 
summer, which wiU strike easily if planted in a border of light earth, and which may be potted in autumn, in
