‘leaflets shorter than the ray, very hispid on the lower part which 
encircles the seed, and terminating in a lanceolate, rather blunt, 
foliaceous, and scabrous appendage. FLorRets of the ray yellow, 
. wedge-shaped, ending in three unequal lobes almost white; 
ose of the disk yellow, with black anthers. AcH#NIA obcom- 
roth of a shining black, without any trace of a pappus; those of the 
ray as well as the central ones sometimes, but not always, abortive. 
Poputar AND GeoGrapHicaL Notice. This, the only species of 
the genus, belongs to a small group of Composite, called Madiez, all 
natives of California, or the adjoining north-west coast, one species 
only being also found in Chili. Though widely differing in many 
particulars of importance, their genera are connected together by a 
certain resemblance in appearance, and by the circumstance that the 
outer achenia, always without a pappus, are enveloped in the leaflets 
of the involucrum. As no very high importance is usually attached to 
this character, Professor De Candolle observes, in a note to his Pro- 
dromus, that these genera ought strictly to be divided amongst other 
tribes of Senecionidex, and that Oxyura in particular, should, with 
- Madia, be referred to Heliopsidex, but that in natural as well as in 
civil ordinances the strictest justice is often the greatest wrong. The 
same remark may be, in the case of this and several other Senecioni- 
dex, applied to the style, the modifications of which are now con- 
sidered by many as absolute characters of the different great divisions 
of Composite; and yet we have here, as near as words can express it, 
exactly the style of Vernoniacex, with which no one would think of 
uniting Oxyura. G. B. 
INTRODUCTION; WHERE GROWN; CuLTURE. This is one of the 
numerous hardy ornamental plants introduced by the Horticultural 
Society, through their Jate indefatigable collector, Mr. Douglas. It is 
an annual of early growth and pleasing appearance, when raised in 
masses, though certainly not more handsome than many of our own 
neglected annuals, which, however properly rejected from our corn- 
fields, would be great ornaments to our garden if carefully sown in 
large masses. Our drawing was made in the Horticultural Society’s 
Garden. It requires but the care demanded 2 annuals generally. 
DERIVATION oF THE Nam 
Oxyura, o£ve sharp, and ovpa a tail, in allusion to the sharp appendages, as 
they are called, to the branches of the style, although in fact these — 
constitute the whole of the branches, CarysantHEeMmorpes, chrysanthe 
like.
