I refer this plant to Hymenoxys with some degree of doubt, 
arising chiefly from its undivided leaves. The flowers and 
fruit and pappus seem entirely to belong to that Genus, and 
the powerful odour of Chamomile exhaled, when the capitula 
are bruised, is also characteristic of Hymenoxys. The specimens 
are a span or more high, much branched, herbaceous; the leaves 
about an inch long. The peduncles are quite naked, terminat- 
ing every branch and bearing a solitary yellow flower.
