Common Snowberry
Symphoricarpos albus var. albus
Synonyms: Symphoricarpos albus var. pauciflorus, Symphoricarpos pauciflorus, Symphoricarpos racemosus

The photo above shows a close-up of the terminal
inflorescence and paired leaves of common snowberry as seen at SnowKing SnoPark
on the southern flanks of Mt. Adams......July 1, 2005. Note
the short, bell-shaped corolla tube of the flowers. The photo doesn't show enough details so this could be variety laevigatus rather than var. albus.
