Pilea, with 600–715 species, is the largest
It is distributed throughout the tropics, subtropics, and warm temperate regions (with the exception of Australia and New Zealand).
Description
The majority of species are shade-loving
Uses
Pilea is of little economic importance; one species is used in
Horticulture
Six species have horticultural value (P. cadierei, P. grandifolia, P. involucrata, P. microphylla, P. nummulariifolia, and P. peperomioides),[2] Some pileas are grown for their ornamental
The ASPCA includes many pilea species in the list of plants that are non-toxic to pets.[4]
Systematics
The genus has attracted little monographic attention since Weddell (1869), and the majority of taxonomic contributions have come from floristic treatments. To date, 787 species names have been published (International Plant Names Index, 2003) and estimates for the species number range from 250 to 1000.[5] Based on previous floristic treatments, about 30% of the species from regions not yet covered by contemporary floristic treatments may be undescribed.
The genus name Pilea is Latin for "felt cap", a reference to the calyx covering the achene.[6]
