Thomasia grandiflora

Thomasia grandiflora, commonly known as large-flowered thomasia,[2] is endemic to the south-west of Western Australia. The flowers are pinkish-purple with a papery appearance hanging in pendents from the leaf axils. The calyx lobes are prominent and larger than the petals.

Description

[edit]

Thomasia grandiflora is a small shrub that grows to about 1 m (3 ft 3 in) high and wide. The dark, bright green leaves vary in shape, usually heart-shaped or occasionally narrowly elliptic, slightly flexible, leathery and 15–25 mm (0.59–0.98 in) long. The flowers have wide, conspicuous, pinkish-purple calyx lobes that are more prominent than the petals. The calyx is thicker near the mid-vein. The small petals are densely covered with star-shaped hairs, occasionally with only a few scattered hairs. The flowers have a papery texture and about 2 cm (0.79 in) across on short pendant stalks. The flowers are followed by capsules containing black seeds that are shed from the plant when ripe. Flowering occurs from winter to spring.[3][4][5]

Taxonomy and naming

[edit]

Thomasia grandiflora was first formally described by botanist John Lindley in 1839 who published the description in A sketch of the vegetation of the Swan River Colony in 1839.[6][7] The specific epithet (grandiflora) is from the Latin grandis meaning "large" or "great"[8]: 378  and flos meaning "flower"[8]: 338  referring to the large flowers of the species.[5]

Distribution and habitat

[edit]

Large-flowered thomasia is a widespread species, mostly found in near-coastal locations growing in open forest in the south-west of Western Australia.[5]
