A very distinct species well characterized by its short flowers. It 
has much the appearance of Pavetta indica L., so far as vegetative 
characters are concerned, but is not at all closely allied to that species; 
it is suggestive of Pavetta involucrata Thw., of Ceylon, but is very 
different from that species.

This species is common and widely distributed in Luzon. There are at 
present 21 specimens in the Herbarium of the Bureau of Science, all from 
that Island, the Provinces of Isabela, Abra, Bontoc, Benguet, Ilocos Sur, 
Union, Pangasinan, Zambales, Pampanga, Rizal, Bataan, Laguna, and 
Batangas, being represented.
