Geology (mantle petrology & volcanology) and botany adventures between Hawaiʻi and Utah.
Vaccinium_sultan on IG and elsewhere.
Plants called Vaccinium reticulatum outside of East Maui and Hawaiʻi Island are V. x pahalae. Vaccinium peleanum is a high elevation species typically with purple-blue fruit and glaucous leaves. Skottsberg lumped it into V. reticulatum but we don't follow Skottsberg's classifications in this home.

There is also a clinopyroxene xenocryst to the left of the xenolith. eruptions here were phreatomagmatic and thus highly explosive. Plant fossils preserved in the tuff are often so well preserved we can identify them down to the species.

I do have a few pictures of Hawaiian garnet pyroxenite mantle xenoliths posted on here. They have a midlithospheric origin from an elevated geotherm and the cpx tends to be darker as they are often quite augitic.
