Distribution and Ecology

New Guinea. "A species usually found in the upper montane and subalpine regions, sometimes venturing out into the alpine grasslands, or a survivor from burned subalpine shrubberies replaced by grasslands, 1750-3810 m. Flowers March - October" (Van Royen 1979). Based on data from 46 collection localities, its climate preferences include a mean annual temperature of 12.5°C, with an average minimum in the coldest month of 6.3°C, and a mean annual precipitation of 3148 mm (Biffin et al. 2011, Table S5).

Regional distribution is as follows (Van Royen 1979):

"WNG. Wisse Lakes, Carstensz Mts, Ilaga area, Mt. Doorman, Mt Wichmann, Lake Habbema, Star Mts.

"TNG. Sirius plateau, Mt Hagen, Kubor Range, Pengagl Creek - Mt Wilhelm area, Mt Kerigomna, Mt Otto, Mt Michael, Mt. Piora, Mt Amungwiwa.
