Angelica lineariloba
species of plant
Angelica lineariloba is a species of Angelica known as poison angelica or Sierra angelica. It is native to the Sierra Nevada and nearby slopes and flats in California and western Nevada from 6000 to 10,600 ft in elevation. This is a taprooted perennial herb producing an erect, hollow stem up to about 1.5 meters tall. The large but feathery leaves are made up of many highly dissected leaflets which are linear to threadlike in shape. The inflorescence is a compound umbel with up to 40 rays holding clusters of small white to cream flowers. There are papery sheaths at the base of each petiole where it branches from the stem (see image at left). The plants overall are rather similar to the other large umbellifers cow parsnip and swamp whiteheads, but cow parsnips have huge lobed but undivided leaves, while swamp whiteheads have pinnate leaves and the individual flowerheads are dense, round balls.

Why this record matters
“Angelica lineariloba” is worth following because a concise public description often conceals a longer documentary argument. Here, Angelica, lineariloba and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jun 28, 2025. The linked authority identifier is Q4762685. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1996.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
