Pollination of the Ericaceae: Chamaedaphne
In Alaska, nonstratified seeds of Diapensia lapponica, Chamaedaphne
calycidata, Saxifraga tricuspidata and Ledum decumbens showed no or few germinating seeds under short-day conditions (Densmore, 1997).
Bogs in the Northern Lakes Region of Indiana are characterized additionally by the presence of a distinctive suite of ericaceous shrubs including Andromeda glaucophylla, Chamaedaphne
calyculata, and Vaccinium macrocarpon, along with carnivorous plants such as Sarracenia (Homoya et al.
The authors compared the usage and distribution of two plant species reaching their range limit in different parts of Estonia: leatherleaf Chamaedaphne
calyculata (common in eastern Estonia, Figures 5 and 6) and bog myrtle Myrica gale (common in western Estonia, Figures 7 and 8).
The signature plants of the bogs, Chamaedaphne
calyculata, and the fen, Potentilla fruticosa, were NA positive, whereas Sphagnum spp.
