Bentham and Hooker (Gen. Plant. ii. p. 381) refer Mendezia bicolor to Spilanthes ; but 
having very carefully examined Coulter and Seemann’s specimens which were referred 
to Zinnia, in Kew herbarium, we identify them with Delessert’s figure, and we think it 
should be referred to this genus. Coulter and Seemann’s specimens have rather broader 
leaves, and are much more branched than the plant figured; but in floral structure 
they agree almost exactly. The disk-flowers in Coulter’s specimens are bidentate and 
uniaristate, whilst in Seemann’s the awn appears to be always wanting.
