“Polar semi-desert dominated by mountain avens ( '' Dryas octopetala ''), Ny Ålesund, Svalbard.”
“In the Arctic, extremely steep environmental gradients are frequent on a microtopographical scale and ecotypic differentiation has been demonstrated over such short distances for alpine timothy (Phleum alpinum ), Carex aquatilis , mountain avens , and purple saxifrage , all widely distributed plant species in the Arctic.”
“Such an effect was demonstrated for mountain avens ( '' Dryas octopetala '') on Svalbard during a warm period in early winter  (see previous subsection on projected temperature responses).”
“White mountain-avens may cover entire ridges in the Alaska Range, associated with moss campion, black oxytrope, arctic sandwort, lichens, grasses, and sedges.”
“Today, introduced annual grasses, including various species of avens, brome, fescue, and barley, occupy most of the remaining grassland areas.”
“The alpine vegetation is typically tundra, and includes discontinuous patches of low-growing heather (Ericaceae), sedge (Carex spp.), and mountain avens (Dryas hookeriana).”
“Surface material deposits from glaciers and icefields form moraines which are colonized by lichens and mosses, horsetail Equisetum sp., willows Salix spp., fire weed Epilobium sp., and mountain avens Dryas drummondii.”
“Alpine vegetation is also characterized by heather (Ericaceae) with sedges (Carex spp.) and mountain avens (Dryas hookeriana) on warmer sites.”
“The dwarf scrub communities are dominated by crowberry (Empetrum nigrum) and include other ericads (Vaccinium spp.), arctic willow (Salix arctica), and white mountain-avens (Dryas octopetala).”
“In the colder alpine regions, mountain avens (Dryas hookeriana), dwarf shrubs, forbs, grasses, and lichens constitute the main vegetative cover.”

A place for me to keep words I found (or found anew) while reading Diana Gabaldon's Outlander series. (Culling my enormous "Learned (or Encountered) in Reading" list.)
