Loasa was the name originally given to the genus by 
Adanson, as supposed, in compliment to some Spanish bo- 
tanist, but why it should have been altered to Loosa by 
Linnzeus we are not told, and are inclined to believe the 
difference to be a misprint. Sir James Smith adopts the 
spelling in the works of Linnzeus; we have adhered to that 
of Adanson. — 
The present is, we believe, an unrecorded species, 
though a sample gathered by Mr. Menzies at Valparaiso, 
and preserved in the Banksian Herbarium, is inscribed, 
with a quere, Loasa acanthifolia; a denomination that will be 
found, on investigation, to belong to a very distinct species 
from this. In fact, the subject of this article comes nearer 
to Loasa hispida (ambrosicfolia of Jussieu) than to any we 
know of; but there the foliage is alternate, of another 
form, and less divided. . 
The drawing was taken from a plant raised by Mr. Grey 
Bennett, in his hothouse at Walton upon Thames, from 
seed from Valparaiso, and is the first of the genus known 
to have appeared in the gardens of this country. 
The group, as far as we are acquainted with it, belongs 
entirely to South America, and seems to abound principally 
in Chili and Peru. Some of the species are of great beauty 
with large brilliantly coloured flowers. Many of them, like 
the present, are covered with a stinging pubescence, and 
require to be handled with the same caution as our common 
Nettle. 
The genus was first appended by Jussieu to his Onagra- 
rie, but afterwards formed, along with MenrzeE ta, into a 
separate order, by the title of Zoasew. The order agrees
