<i>Calandrinia</i> sp. Boolardy Station (P. Jayasekara 719-JHR-01) is a synonym of <i>C.</i> <i>mirabilis</i> (Montiaceae)

Calandrinia mirabilis Chinnock & J.G.West was described by West and Chinnock (2013) as a large (5-15 cm tall, 10-120 cm diam.), prostrate to decumbent annual with fleshy, spathulate, basal leaves that become shorter and spathulate to obovate along each stem/scape, which usually terminates with an inflorescence axis of 3-7(-15) flowers.The flowers can be very large and showy (up to 45 mm diam.) and are medium pink to magenta in colour with irregular white, orange-red and yellow bands in the lower third, with 8-11 petals, 4 stigmas, and numerous stamens (e.g.F. Obbens & R. Davis FO 9/13 PERTH 08477361, https://www.inaturalist.org/observations/75628598).The capsules are 4-valved.Initially the valve tips barely separate (i.e. a pore-like opening); however, they may open further with maturity.Capsules appear square in cross section due to the valve abscission lines becoming slightly thickened and raised.Each capsule has many reniform to sub-reniform, shiny, mid to dark tan seeds, c. 0.6 mm long, 0.45 mm wide, with a very fine, colliculate, surface pattern.Prior to being formally named, C. mirabilis was recognised at PERTH from 2009 by the phrase-name C. sp.Mt Clere (R.J. Dadd 5).At the time that name was erected, this taxon was known only from relatively few collections from Mt Clere, Walburg and Landor Stations in the mid to upper Gascoyne River catchment.
