Unfortunately, I was using a new lens, so I need to go through the learning curve of what works technique-wise–you may notice that the last two photos have unintentional soft-focus issues. I wouldn’t normally share these images (and I have better ones of these species), but I’m including them to show the local parents of the hybrid in the first image.
Phyllodoce × intermedia (first image) is a first-generation cross (often) of the whitish- to greenish-yellow flowered Phyllodoce glanduliflora and the pink- to purple-flowered Phyllodoce empetriformis. As noted in the Flora of North America entry for purple mountain-heather (Phyllodoce empetriformis),
Phyllodoce × intermedia…[has] a decidedly intermediate floral morphology, combining glandular, mostly nonciliate sepals more than 3 mm long and pinkish, cylindric to ovoid corollas.
I hope the intermediateness is evident in these photographs. Compare: presence/absence and length of hairs on the flower-supporting pedicels among the three; corolla (flower) colour; presence/absence of glands on the sepals; presence/absence and length of hairs on the corolla; and corolla shape (urceolate or urn-shaped in Phyllodoce glanduliflora, campanulate or bell-shaped in Phyllodoce empetriformis, and something in-between for the hybrid).
As the name implies, mountain-heathers are plants of montane to alpine habitats (though I most frequently associate them with the upper montane–just below the altitudinal zone where one starts to find subalpine meadows). These particular plants were growing along the shore of Quiniscoe Lake, within a coniferous forest.
Sevon or eight species of Phyllodoce are recognized worldwide, five of which occur in the western and northern parts of North America. Parts of Europe and Asia also have species of Phyllodoce.
