Nomenclatural Notes
Status: nom. illeg. later homonym non P. exilis (A. Gray) A. Gray (1873).
Remarks
From his P. exilis (A. Gray) A. Gray (1873), Gray excluded its basionym Aphantochaeta exilis A. Gray (1856) and cited the latter as a synonym of P. exilis A. Gray var. aphantocheta (cf. St. Louis Code Art. 48.1).
