Helichrysum luteoalbum, commonly known as Jersey Cudweed or Weedy Cudweed, is a cosmopolitan weed. It grows as an erect herb up to 70 centimetres high, branching from the base. Flowers are cream, yellow, white, or pink.[1] This species is so widely distributed that it is unclear where it is native and where naturalised. In general it is considered naturalised in North and South America, and native to every other continent.[5] Confusion between Pseudognaphalium affine and Pseudognaphalium luteoalbum: Both appear to be quite close as per Keys in Flora of Pakistan, as below:
Keys are also available in Flora of China, with phyllaries silvery gray to yellowish in Pseudognaphalium luteoalbum as per description in it. Other important aspects as per keys are: Dwarf herbs, 10-40 cm tall; leaves 1-veined Annual herbs; leaves spatulate or spatulate-oblong, apex obtusely rounded, base narrower. P. luteoalbum Stems white lanate; leaf base decurrent, sometimes slightly amplexicaul; capitula 2-4 mm in diam. Dwarf herbs, 10-40 cm tall, usually branched from base; leaves spatulate or spatulate-oblanceolate, not amplexicaul or auriculate, whitish tomentose on both surfaces; pappus connate at base. P. affine Specimens in GBIF can be seen at P. luteoalbum (specimen one, two and three and four) and P. affine (specimen one, two). Based on the above, I will have a relook at different posts in our database. On further checking, I found that Pseudognaphalium luteoalbum is not mentioned in The checklist of Nepal and there is only one specimen of it from India in GBIF out of the total 18,062 available in GBIF. .
Wild Weed For ID : California : 19FEB15 : AK-21 : 4 posts by 3 authors. Attachments (1) Small, wild weed seen in Fremont on 27/9/14. Id please. Probably a Gnaphalium sp.
