Description
editHypocalymma angustifolium is an erect, multistemmed shrub that typically grows to a height of up to 1.5 m (4 ft 11 in). Its leaves are linear, triangular in cross-section, channelled on the lower surface, and glabrous, mostly 15–30 mm (0.59–1.18 in) long and 0.8–1.2 mm (0.031–0.047 in) wide. The flowers are arranged singly or in pairs in leaf axils, and are sessile with short bracts and bracteoles at the base. The sepals are thin, membranous, about 1.5 mm (0.059 in) long. The petals are about 8 mm (0.31 in) across, white to cream coloured or occasionally pink, egg-shaped with the narrower end towards the base, 3.0–3.5 mm (0.12–0.14 in) long. There are usually 25 to 35 stamens with the filaments joined at the base, and about the same length as the petals. Flowering occurs from June to October and the fruit is a capsule 4–5 mm (0.16–0.20 in) in diameter.[2][5][6][7]
Taxonomy
editHypocalymma angustifolium was first formally described in 1837 by botanist Stephan Endlicher, who gave it the name Leptospermum angustifolium in Enumeratio plantarum quas in Novae Hollandiae ora austro-occidentali ad fluvium Cygnorum et in sinu Regis Georgii collegit Carolus Liber Baro de Hügel, from specimens collected by Charles von Hügel near the Swan River.[8][9] In 1843, Johannes Schauer transferred the species to Hypocalymma as H. angustifolium.[10] The specific epithet (angustifolium) means 'narrow-leaved'.[11]
Distribution and habitat
editWhite myrtle is widespread between Eneabba and Ravensthorpe and inland to Manmanning and Wagin in the Avon Wheatbelt, Esperance Plains, Geraldton Sandplains, Jarrah Forest, Swan Coastal Plain and Warren bioregions. It grows in sandy soil, often in somewhat swampy places.
Use in horticulture
editThis species can be maintained as a well-rounded bush in cultivation and is suitable for growing in a container.[7] It requires good drainage and prefers a position in partial shade, protected from heat and wind.[7] It has a degree of frost-resistance.[7] Flowering stems may be cut for floral arrangements[3]
