*This is actually Quercus x welshii, a hybrid recognized in 'The Flora of Colorado', key from CSU, but not by iNaturalist nor TNRS

Flowers: White, 5 petal, numerous stamen; hanging in cylindrical cluster (2 - 3").
Leaves: Simple, alternate, oval, finely serrate.
Twigs: Slightly bitter odor when scratched.

Note: Key & TNRS both acknowledge name"Padus virginiana subsp. melanocarpa", however iNaturalist does not recognize as a species

Flowers: Yellow in pairs, cylindric to campanulate, petals united, subtended by 2 elongated red leaf-like cupped bracts.
Leaves: Opposite, simple, ovate to elliptic, red venation on underside.

*Distegia involucrate is both the name in my key and the TNRS accepted name, however iNaturalist does not recognize it as a species

Leaves: Alternate, elliptic.
Fruit & leaves appear to be finely tomentose, however actually a 'peltate scale', giving foliage a silver-satin tint.
