florets being much more numerous, and each blotched at the base with a rich purplish-brown so as to form a ring 
inside the flower round the disk. "When the florets of the ray fall, the same peculiarity is observable in the 
florets of the disk as was described in the preceding species, excepting that they are much less dry. The species 
is a native of the Cape of Good Hope, and was introduced about 1835. Its seeds are now common in the 
seed-shops, and they should be sown in February or March, covering them at night, if the weather should be 
cold, with a flower-pot or glass, when they will come into flower in May. Mr. Hopgood, of the Bayswater 
nursery, has some plants of this species still beautifully in flower this day, October 7th ; though the specimen 
figured in our plate was gathered from one of the samo plants early in May.

Description, &c. — This beautiful little plant is one of those which we owe to the exertions of poor Douglas, 
it having been sent home by him from California in 1835. It is quite hardy, and should be sown in March or 
April, when it will come into flower early in June. It does not, however, last long ; and the seeds are generally 
ripe in July or August.

Descbiption, &c The plant is of no beauty ; but we notice it on account of its having been lately cultivated 
on a large scale both in England and Germany, for the purpose of crushing the seeds for oil. In Germany, it 
has been cultivated near Stuttgard, and in England, in Norfolk, by Mr. Taylor ; in both instances, the experiment 
has been attended with success. The plant is a native of Chili, whence it was introduced in 1794 by Archibald 
Menzies, Esq. In its native country this plant is celebrated for producing oil, and indeed the name of Madia is
