434 FLORA NIGRITIANA. 
paleze of the receptacle represent the subtending bracts, and the 
appendages in question a pair of opposite bracteole on the 
pedicel (callus basilaris) of the flower; and it is well known 
how very rarely the presence or absence of such bracteole can 
be made available even as a good generic character. In the 
Coronocarpus Prieureanus, they are generally smaller than m 
C. Kotschyi, but occasionally as much as } of a line long. 
Whether the genus should be referred to Hcliptee among 
Asteroidee, or to Coreopsidee among Senecionidee, is a matter 
of doubt. Its close affinity is evident with Blainvillea, Wedelia 
and Viguiera, genera now classed in three different subtribes.
