Microseris scapigera is a yellow-flowered daisy, a perennial herb, found in New Zealand and Australia. It is the only New Zealand species of Microseris, and one of three Australian species along with Microseris lanceolata and Microseris walteri. It is classified in a group of plants, the tribe Cichorieae, that includes chicory and dandelion.
The murnong or "yam daisy" has been referred to M. scapigera, M. lanceolata, or M. forsteri, but is now classified as M. walteri.
Now rare and vulnerable due to loss of habitat.{{Cite web|title=Flora of Victoria|url=https://vicflora.rbg.vic.gov.au/flora/taxon/0227cb8c-4a85-47ae-9b9e-24d4ba831aae|access-date=2020-06-26|website=vicflora.rbg.vic.gov.au}}
Taxonomy and nomenclature
Joseph Banks and Daniel Solander collected specimens of the plant in New Zealand in 1769 or 1770, but Solander's manuscripts were never published. The locality of their collection is stated by later authors as either the Bay of Islands or Queen Charlotte Sound (Totara nui). Georg Forster (1786) listed the name "Scorzonera scapigera S." in an appendix without description.{{cite book |last1=Forster |first1=Georg |title=Florulae Insularum Australium Prodromus |date=1786 |publisher=Joann. Christian Dietrich |location=Göttingen |page=91 |language=la}} Species 534. [https://www.biodiversitylibrary.org/item/41812#page/99/] Allan Cunningham gave a brief description in 1839, mentioning Solander's manuscripts and Banks' specimens plus another specimen collected by his brother Richard.{{cite journal|last1=Cunningham|first1=Allan|date=1839|title=Florae insularum Novae Zelandiae precursor|url=https://www.biodiversitylibrary.org/page/42901188#page/137|journal=Annals of Natural History|volume=2|issue=8|page=125|doi=10.1080/00222933809512347 |quote=1.

Joseph Dalton HookerKnown as "Hooker filius" to distinguish him from his father, and abbreviated as "Hook. fil." or "Hook.f.". thought that the species didn't belong well in Scorzonera: he had proposed a subgenus, then placed it in Microseris, beside M. pygmæa of Chile.Raoul had applied the name of Chilean Microseris pygmæa (Hook. et Arn.) DC to a New Zealand species, presumably this one. (Raoul Choix des Plantes, p. [https://gallica.bnf.fr/ark:/12148/bpt6k1025092h/f55.image.r=Microseris 45]; de Candolle Prodromus pp. 88–[https://www.biodiversitylibrary.org/item/7156#page/94/ 89]; Hooker & Arnott "Contrib. Flora S.Am. – Compositæ" Comp. Bot. Mag. v. 1 p. [https://www.biodiversitylibrary.org/page/34221204#page/29/ 30].) He gave the name as Microceris Forsteri in 1852,{{Cite book|last=Hooker|first=Joseph Dalton|title=The botany of the Antarctic voyage of H.M. discovery ships Erebus and Terror in the Years 1839-1843: under the command of Captain Sir James Clark Ross.

Raoul, but the species is quite a different one.}} however Cunningham's description with the epithet scapigera takes precedence. Carl Heinrich Schultz 'Bipontinus' published the combination Microseris scapigera in 1866, listing Hooker's M. forsteri and Forster's S. scapigera as synonyms.{{cite journal |last1=Schultz |first1=C.

Neither Hooker nor Schultz referenced Cunningham's description; in 2015 Sneddon designated a lectotype for Schultz's name.APNI citation [https://id.biodiversity.org.au/instance/apni/5371511 5371511] "Nova Zelandia [New Zealand]. near Totara nui [Queen Charlotte Sound], 1769, Banks and Solander; lecto: (here chosen): BM; isolecto: WELT."
Some authorities have grouped M. scapigera with the other Australian forms into single species under the name M. lancifolia, for example A census of the vascular plants of Victoria, Edition 3. (1990) and Australian Plant Census (2011). Sneddon (2015), in Flora of Australia maintained two separate species, and the Melbourne Herbarium has supported both plus a third unnamed species since the early 1990s. The third species was formally described by Neville Walsh in 2016, matching herbarium specimens were identified, and the name M. walteri was selected.
Conversely, M. scapigera has earlier been "misapplied to" M. lanceolata in the Flora of South Australia (1st and 2nd editions, 1929 and 1957) and The Student's Flora of Tasmania (1963).{{cite web |title=Name 73429 (Microseris scapigera) |url=https://biodiversity.org.au/nsl/services/rest/name/apni/73429/api/apni-format |website=Australian Plant Names Index |access-date=5 October 2020}}
Botanical naming
{{Further|Murnong}}
For more than 30 years Murnong was named as Microseris sp. or Microseris lanceolata or Microseris scapigera. Royal Botanic Gardens Victoria botanist Neville Walsh clarified the botanical name of Microseris walteri in 2016 and defined the differences in the three species in the table below.{{cite journal |last1=Walsh |first1=Neville |title=A name for Murnong (Microseris: Asteraceae: Cichorioideae) |journal=Muelleria |date=2016 |volume=34 |url=https://www.rbg.vic.gov.au/documents/MuelleriaVol_34_-_p63_Walsh.pdf}}

Uses
Plants of Microseris scapigera sensu have no tubers, but roots that are "fleshy, only slightly fibrous, and slightly, but tolerably bitter when eaten raw".{{cite journal |last1=Walsh |first1=Neville |title=A name for Murnong (Microseris: Asteraceae: Cichorioideae) |journal=Muelleria |date=2016 |volume=34 |pages=63–67 |doi=10.5962/p.292268 |s2cid=251001015 |url=https://www.rbg.vic.gov.au/documents/MuelleriaVol_34_-_p63_Walsh.pdf |access-date=4 October 2020}} Indigenous Australians may have eaten this plant also, but historical sources describe murnong as a sweet tuber. The bitterness in Microseris scapigera roots can be removed by blanching the roots in boiling water for 5 minutes, before consumption or further cooking.
Aboriginal populations in southeastern Australia relied on tubers of the daisy yam as a staple,Beth Gott, ‘Murnong — Microseris scapigera: a study of a staple food of Victorian Aborigines’, Australian Aboriginal Studies, no. 2, 1983, pp. 12, 14. and actively cultivated it.{{Citation | author1=Pascoe, Bruce | author-link=Bruce Pascoe | title=Dark Emu : aboriginal Australia and the birth of agriculture | publication-date=2018 | publisher=Magabala Books | isbn=978-1-925768-95-4}} It is known as ngampa in the Thura-Yura languages.Simpson, Jane and Luise Hercus. 2004.
