Type in the U. S. National Herbarium, No. 1,593,569, collected
at Serra do Caraca, Municipio Santa Barbara, State of Minas
Geraes, Brazil, April 13, 1933, by Mello Barreto (No. 874; Herb.
Jard. Bot. Betto Horizonte No. 5465).
This plant is remarkable for its dense, fine indument, which gives
a decided ashy color to the under side of the leaves and to the outside
of the flowers. The sepals are broadly keeled, almost as broadly
as in P. Parritae, a species of the wholly unrelated subgenus Tacsonia.
