found to belong to some other genus ; but, although certainly not a Chrysopsis, it 
does not appear to agree with the character of any other known genus, but to 
form a new one in that group of Heleniee calle by {\rrey and Gray the Eugail- 
lardie. 'The form of the style is not, it is true, decidedly that of either of the four 
first great divisions of Composite, for the branches are not so flat as in Asteree, 
there is no tuft of hairs at the base of the sterile portion as in most Senecionidee, 
the branches are not obtuse as in Eupatoriacee, nor so hairy as in Vernoniacee ; 
we must therefore be guided by the secondary characters derived from the com- 
bination of the opposite leaves, yellow flower, paleaceous pappus, &c., in fixing 
its place amongst Senecionide of the tribe Heleniew. In this tribe the nearest 
affinities of Oxypappus are on the one hand with Palafowia, on the other with 
Hymenoxys, but it is abundantly distinct from both. I have borrowed the generic 
name from a sectional one, once proposed by De Candolle for a species of 
Hymenoxys, now unoccupied, as that plant is adopted as a genus (by Fischer and 
Meyer) under Nuttall’s name of Péilomeris.

This second species, nearly allied to the Californian one described and figured 
above (p. 23, pl. xv.), does not throw any further light on the affinities of the 
genus. The style (represented in the plate with rather too broad branches) brings 
it nearer to Asteree than to Senecionide, but the leaves are opposite and the aspect 
of the plant not unlike that of Galnsoga. It may, therefore, be better placed 
among the Euheleniee than at the end of Asteree.
