Pallenis spinosa
species of plant
Pallenis spinosa, commonly known as spiny starwort or spiny golden star, is an annual herbaceous plant belonging to the genus Pallenis of the family Asteraceae. The Latin name of the genus is derived from palea (chaff), referring to the chaffy receptacle, while the species name spinosa, meaning spiny, refers to the spiny bracts surrounding the flowers.
Description
Pallenis spinosa reaches on average 60 centimetres (24 in) of height. Leaves are alternate, lanceolate or elliptical. The basal ones have short petioles, while the cauline ones are sessile or semiamplexicaul. A solitary inflorescence grows at the top of the branches. The large, slightly convex receptacle shows numerous, yellowish orange, hermaphrodite disc florets and two whorls of yellow ray florets. The long, villous, involucral bracts end in an apical sharp-pointed spine. The flowering period extends from May through July. Fruits are achenes of about 2–2,5 millimeters of length.
This brief starts where responsible research should: with the source description of “Pallenis spinosa” as species of plant. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 17, 2025. The linked authority identifier is Q1547224. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
