Description

Caladenia caesarea is a terrestrial, perennial, deciduous, sympodial herb with a single, erect, hairy leaf 100–180 mm (3.9–7.1 in) long and 2–5 mm (0.079–0.197 in) wide. The plant is 150–350 mm (5.9–13.8 in) high with up to three mustard-coloured or lemon-yellow flowers with a brownish-red labellum, with two rows of glossy yellow calli along its mid-line. The flowers are 50–100 mm (2.0–3.9 in) long and 40–70 mm (1.6–2.8 in) wide. [2] [3] [4]

Taxonomy and naming

This orchid was first formally described in 1912 by Karel Domin who gave it the name Caladenia filamentosa var. caesarea in the Journal of the Linnean Society, Botany from specimens collected by Arthur Dorrien-Smith near Bridgetown in 1909. [5] In 1989, Mark Clements and Stephen Hopper raised the variety to species status as Caladenia caesarea in Australian Orchid Research. [6]

In 2001, Hopper and Andrew Brown described three subspecies of C. caesarea in the journal Nuytsia , and the names are accepted by the Australian Plant Census:

Distribution and habitat

Subspecies caesarea grows in seasonally wet areas between Wagin, Tenterden and Busselton in the Avon Wheatbelt, Jarrah Forest and Mallee bioregions of south-western Western Australia. [4] [10] Subspecies maritima grows on granite and rock outcrops and is restricted to the Leeuwin-Naturaliste National Park and Ludlow areas of the Jarrah Forest bioregion, [4] [11] and subsp. transiens grows in shallow soil in open mallee in disjunct locations in the Jarrah Forest bioregion.
