Kugler — Platythrea

February 1975 by W. L. and D. E. Brown. The collections were 
both made from small colonies found under limestone slabs in 
pine forest ( Pinus occidentalis) with some form of everlasting 
prominent in the understorey ( Gnaphalium or a related species 
in Compositae: Inuleae) along the road from Cabo Rojo to the 
Alcoa bauxite mines. The first collection was made at Km 28, 
elevation about 1200 m, and the second at Km 33 (1500 m). Al- 
though special attention was paid to the rotten wood microhabitat 
in 3 weeks of intensive collecting all over the Dominican Republic, 
no P. strenua were found anywhere else in the country.
