“ The whole plant is much less hairy than the preceding ; the stems are
taller, and diffusely branched, rounded, and of a dark red colour ; the older
ones becoming frequently nearly smooth. The leaves are narrower, more
pointed, and often entire, particularly the uppermost ; the radical ones are
more deeply divided. The capitula are solitary, and on longer purplish
peduncles. The rays are longer, narrower, and o f a deeper orange yellow,
nearly twice the length of the involucrum, which is furnished at the base
with a solitary bractea : in both species they are generally 8 in number. The
paleæ are much more deeply coloured, almost black, while in triloba they
are of a chestnut colour.” D . Bon Mss.

hase of the Achenia. 3. Floret spread open. 4. The 5 Stamens spread open to show the
