About Angelica lineariloba subsp. scabrida (Clokey & Mathias) C.Y.Liao & S.R.Downie
Angelica lineariloba is a species of the genus Angelica, commonly called poison angelica or Sierra angelica. It is native to the Sierra Nevada, as well as adjacent slopes and flats in California and western Nevada, growing at elevations between 6000 and 10,600 feet. This is a taprooted perennial herb that grows an erect, hollow stem reaching up to roughly 1.5 meters tall. Its large, feathery leaves are composed of many highly dissected leaflets, which range in shape from linear to threadlike. The plant's inflorescence is a compound umbel with up to 40 rays, which hold clusters of small flowers that are white to cream in color. Papery sheaths form at the base of each petiole where it branches from the stem. This plant is overall similar in appearance to two other large umbellifers: cow parsnip and swamp whiteheads. However, cow parsnips have large lobed, undivided leaves, while swamp whiteheads have pinnate leaves and individual flowerheads that form dense, round balls.
