The compound flower cluster identifies angelica grayi as a member of the carrot family (apiaceae). The plant produces a thick, grooved stalk bearing pinnate leaves at widely spaced, alternate intervals, and terminates in the spherical umbel, formed of around 20 separate clusters (umbellules), each containing several dozen small white flowers. These have a green center, surrounded by tiny white petals, with several protruding stamens. The base of the leaf stalks clasp the main stem, which is green at first, becoming reddish when mature.
