Loiseleuria

 

a genus of plants of the family Ericaceae, comprising a single species, the alpine azalea (Loiseleuria procumbens). They are prostrate evergreen subshrubs, which form thick pulvinate mats. The leaves are small, crowded, leathery, and opposite. The pink or white flowers are gathered in groups of two to five at the end of branches in an umbel-like raceme. The alpine azalea, which grows on bald mountains, in rocky lichen-covered and thicketed tundras, and in groves of dwarf stone pines, is distributed in the circumpolar and northern regions of Eurasia and North America, as well as in the mountains of Eurasia. It is cultivated in rock gardens.

Within this family, Alpine azalea Loiseleuria procumbens was particularly appreciated (1.95% of total diet volume), although its consumption has never been reported in previous studies on chamois diet.
This was true for three species that were present in the diet of both chamois and red deer (Carabelli 2008): Juniperus communis, Calluna vulgaris and Loiseleuria procumbens.
The monophyly of a clade comprising Leiophyllum, Loiseleuria, and Kalmia (i.e., Kalmia s.l.) also has been strongly supported in a detailed phylogenetic analysis of this group (Kron & King, 1996).
