#compositae — Public Fediverse posts

Thanks to Mauricio Bonifacino and Matt Taylor (Identic), the Lucid Key to the tribes of Compositae is now back online after having disappeared from the web for a few years:

The pappus of the Australian daisy Angianthus tomentosus consists of jagged scales topped by feathery bristles. #daisies #asteraceae #compositae

The flattened cypsela of Brachyscome aculeata, Australia. #daisies #compositae #asteraceae

The feathery pappus (parachuting hairs) on the cypsela (fruit) of Rhodanthe spicata from Western Australia. #asteraceae #compositae #dasies #microscopy

New England aster (𝘚𝘺𝘮𝘱𝘩𝘺𝘰𝘵𝘳𝘪𝘤𝘩𝘶𝘮 𝘯𝘰𝘷𝘢𝘦-𝘢𝘯𝘨𝘭𝘪𝘢𝘦), from yesterday's hike:

Wait a second, why does this herbarium sheet of a Calotis have the cypselas of a Rutidosis?

I guess that should teach me not to rely blindly on the specimen identifications of more senior botanists.

Very happy that my Kleinia is finally producing its first flower-head. #asteraceae #compositae #succulents

Happy to have seen Celmisia sericophylla, which stands out among Australian Celmisias with its leaves woolly also on the upper side. The species is endemic to Victoria. #asteraceae #compositae #botany

Craspedia costiniana, Koscuisko National Park, New South Wales, Australia. This alpine daisy is easily recognised by the very long hairs on the leaves. #asteraceae #compositae #daisies

Euchiton limosus, an Australian cudweed, with a pollinator. Victorian alps. #asteraceae #compositae #daisies

Ewartia nubigena, an Australian 'Edelweiss' equivalent. Different genus but same tribe of #daisies, and similar appearance as an alpine cushion plant. North of Thredbo, New South Wales. #asteraceae #compositae

Daisies are somewhat thin on the ground in the wet tropics, but I am seeing a few common weeds. Here Emilia sonchifolia ('lilac tasselflower') and Sphagneticola trilobata ('Singapore daisy'). #asteraceae #compositae

Interesting outcome of my vacation in Cairns. Noticed this weedy #daisy at the caravan park, was puzzled what it was. After Frank Zich of the Australian Tropical Herbarium identified it as Erigeron bellioides, it turned out that while it was already on the Queensland Plant Census, it wasn't on the Australian national one. Now being added. #asteraceae #compositae #weed

Have recently been trying out some field/vacation options for #microscopy, and I am warming up to the Apexel 200x smartphone microscope. Fiddly to centre over the camera lens, admittedly, but okay for what it is. Here the pappus of Tridax procumbens #asteraceae #compositae

Dittrichia graveolens (Inuleae), 'stinkwort', now flowering in the ACT. Originally from S Europe, N Africa, and NW Asia. #asteraceae #compositae

From a few weeks ago, but I think I didn't post it then: Ozothamnus cupressoides in Kosciuszko National Park, New South Wales. The fitting species epithet refers to the cypress-like scale leaves of this shrub. #asteraceae #compositae

Volume 2 issue 2 of CAPITULUM is out!

Cassinia quinquefaria in full bloom on Black Mountain, ACT. #asteraceae #compositae

Related Ozothamnus diosmifolius is commonly called rice flower, but it has more globular flowerheads, and looking at this species, I think it would actually deserve the name more.

Coronidium waddelliae near Kiandra, New South Wales. Not sure I have ever seen it a prolific as this year. #asteraceae #compositae

Just outside of Dalgety, New South Wales, we found three introduced Erigeron (Conyza) growing side-by-side: canadensis, sumatrensis, bonariensis. #asteraceae #compositae

Cassinia monticola near Kiandra, New South Wales, Australia. #asteraceae #compositae

Chrysocephalum semipapposum near Nimmo, New South Wales, Australia. #asteraceae #compositae

Chondrilla juncea, Canberra, ACT, Australia. A nearly leafless roadside weed with a vaguely asparagus-like appearance before if flowers. #asteraceae #compositae

Flowerheads of Ozothamnus cuneifolius, near Merimbula, NSW, Australia. #compositae #asteraceae

Flowerheads of Euchiton involucratus, an Australian cudweed, in Merimbula, NSW. #asteraceae #compositae
