北美黃櫟 (Quercus muehlenbergii)觀察者
douggoldman描述
Numerous trees of this species growing in a generally rocky, upland forest, many of the rocks appearing to be basalt or something similar. Acorn cap about 1.5 cm diameter.
This species hasn't been documented in Guilford County since the 1960s, but it's still present here in this surprisingly large population.
I was tipped off to this population here by fallen leaves seen in this observation:

山月桂屬 (屬 Kalmia)觀察者
douggoldman描述
Kalmia angustifolia ("a") and K. latifolia ("l"), compared. Effectively cultivated plants, but naturally occurring in a block of surface Sphagnum and peat collected in 2006 from a raised coastal bog in Jonesport, Washington County, Maine. In 2006 K. angustifolia was present but small and sparse in the peat block, but K. latifolia was not evident at all, so it must have germinated later from seed in the peat.
Flower photos taken on 18 May 2022; sterile stems photo taken on 8 June 2022; fruit photos taken on 4 August 2022.
