Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley.

Distribution
Endemic. Confined to the North Island where it occurs locally from Te Paki south to the Hauraki Gulf islands, Cuvier Island and Waitakere Ranges
Habitat
Open or relatively bare clay pans, under short scrub or within rough pasture, in coastal locations. Often seen under tall kanuka (Kunzea spp.) forest where it grows on exposed clay or in shallow leaf litter. Seems to do best in semi-shaded sites.
Features
Small, tufted, non-rhizomatous herb with a simple or multiciple root stock. Roots stout, rather fleshy, closely packed on stock up to 3 mm diameter. Rosette leaves 10-25 x 5-15 mm, grey-green to dark green, ovate, obovate-spathulate, obovate-oblong to obovate-cuneate, margins coarsely or shallowly, often rather distantly crenate-dentate to crenate-serrate or rarely subentire to entire; usually widest at or close to the proximal teeth, tapering from proximal teeth to the base, membranous, both surfaces velutinous, densely clad in soft, fine hairs; apex obtuse sometimes apiculate. Petioles 5-20 mm long, flat to subterete. Cauline leaves 0-3, similar to rosette leaves, smaller. Scapes 10-80 mm long, glabrescent, slender, somewhat wiry, pliant. Capitula 5-10 mm diameter; involucral narrow-oblong, obtuse to acute, glabrescent; hyaline margins narrow. Ray florets numerous, c.30-80, 0.3-0.8 mm long, white, disc florets 10-15 or more, yellow. Cypsela 2.5-2.75 x 1 mm, brown to grey-brown, obliquely obovate, glabrous, margins thickened. Beak stout 0.5 mm long, following curvature of margin.
Similar taxa
Distinguished from the other New Zealand species by the large dark green to grey-green, soft, velvety, coarsely to shallowly serrated or entire, hairy leaves. The seeds of this species are particularly distinctive due to their long, prominently curved beaks. It is most likely to be confused with Solenogyne gunnii, an introduced Australian species, which differs by its oblanceolate to lanceolate leaves, and shorter, densely hairy, rather than glabrescent, fruiting scapes no longer than the longest leaf.
Flowering
September - March
Flower colours
White, Yellow
Fruiting
November - June
Propagation technique
Easy from fresh seed or rooted pieces
Threats
Not directly threatened but generally uncommon throughout its known range. Often grows in rough or poorly maintained pasture reverting to scrub so is vulnerable to pasture improvement
Etymology
lagenophora: From the Latin lagen ‘bottle or flask’ and –phora a Greek suffix denoting a carrier, possibly referring to the urceolate (urn-shaped) cypsela.
Taxonomic Notes
The correct spelling of the genus has been the matter of some debate. Drury (1974) argued that the naming author of the genus Cassini had first spelled the genus as Lagenifera in 1816, and that this spelling therefore took priority over his later Lagenophora (proposed in 1818). Nevertheless Nicolson (1996) put forward a proposal to reject the earlier Lagenifera in favour of Lagenophora, and this proposal was accepted under the Vienna Code (see Art. 14.11 & App. III 2006). Nevertheless this ruling was accidentally overlooked by New Zealand botanists until it was drawn to their attention in 2013 (P. J. de Lange pers. comm. August 2013).
Lagenophora sublyrata, Drury (1974) considered might be better accommodated in Solenogyne - this aspect needs further study. Nakamura et al. (2012) however merged this species, as L. lanata with the Australian L. gracilis a view that has been disputed. The most recent view is that the correct name for this plant is now L. sublyrata (Wang & Bean 2019), this is followed here for now.
