Prostanthera cuneata, commonly known as alpine mint bush,[2] is a species of flowering plant in the mint family Lamiaceae, and is endemic to mountainous areas of south-eastern continental Australia. It is an erect, compact shrub with egg-shaped leaves with the narrower end towards the base, and pale lavendar to almost white flowers with purple blotches.
Prostanthera cuneata is usually an erect, more or less compact shrub that typically grows to a height of 0.5–1.5 m (1 ft 8 in – 4 ft 11 in) but often tending to prostrate as it ages. The branches are more or less cylindrical and covered with white hairs. The leaves are strongly aromatic when crushed, egg-shaped with the lower end towards the base, often appearing wedge-shaped, 4–6 mm (0.16–0.24 in) long, 3.5–5 mm (0.14–0.20 in) wide and sessile or on a petiole up to 0.5 mm (0.020 in) long. The flowers are arranged singly in four to ten leaf axils near the ends of branchlets, each flower on a pedicel 1–2 mm (0.039–0.079 in) long. The sepals are green, usually tinged with purple and form a tube 2.5–3 mm (0.098–0.118 in) wide with two lobes. The lower sepal lobe is 3–4.5 mm (0.12–0.18 in) long and the upper lobe 2.5–4 mm (0.098–0.157 in) long. The petals are pale lavendar to almost white with reddish or purple blotches inside, 9–15 mm (0.35–0.59 in) long, forming a tube 6–8 mm (0.24–0.31 in) long. The lower central lobe is 6.5–9 mm (0.26–0.35 in) long and the upper lobes are 5–6 mm (0.20–0.24 in) long with a central notch 1–2 mm (0.039–0.079 in) long. Flowering occurs from November to April.[2][3][4]
Prostanthera cuneata was first formally described in 1848 by botanist George Bentham in de Candolle's treatise Prodromus Systematis Naturalis Regni Vegetabilis.[5][6] The specific epithet cuneata means "wedge-shaped".[7]
Alpine mint bush occurs in alpine and subalpine closed heath and shrubland in granite-based soils in New South Wales and Victoria, often in association with snow gums (Eucalyptus pauciflora).[8][2] In Tasmania, the species is listed as "presumed to be extinct" under the state's Threatened Species Protection Act 1995.[8] In New South Wales it is found south from the Brindabella Range and in north-eastern Victoria at altitudes between about 1,500 and 2,000 m (4,900 and 6,600 ft).
In cultivation this plant has gained the Royal Horticultural Society's Award of Garden Merit.[9][10] It has an RHS hardiness rating of H4 (hardy throughout most of the UK, down to -5°/-10 °C)[9] and is suited to USDA hardiness zones 8 to 9.[11]

Prostanthera cuneata, es una especie de planta arbustiva del género Prostanthera perteneciente a la familia de las lamiáceas. Es un endemismo de Australia oriental (Estados de Nueva Gales del Sur y, sobre todo, Victoria), incluida Tasmania.[2]
Se trata de un arbusto de una altura de 0,5 a 1m, compacto y denso, fuertemente aromático, con ramas cubiertas de pelos cortos y de glándulas más o menos sentadas. Dichas ramas llevan hojas, sentadas o cortamente pecioladas, glabras, algo espesadas, con el limbo de márgenes enteros o subcrenados, de forma obovada a cuneiforme y con el ápice redondeado a obtuso. Miden unos 4-5mm de largo por 3-3,5mm de ancho y tienen el envés densamente glandular y de un verde más pálido que el haz. Las flores son axilares y concentradas en los nudos superiores en inflorescencias monoflorales con bractéolas caedizas de 3-3,5mm de largo. Dichas flores tienen el cáliz, glabro y de labios enteros, mediocentimétrico con el tubo de 2,5-3mm y el labio superior de unos 2-2,5mm nada o poco acrescente en la fructificación. La corola, interior y exteriormente más o menos veluda, mide 1-1,5cm de largo, con el tubo y la garganta de color blanco punteado/manchado de púrpuro, malva o rojo/naranja, mientras los lóbulos de los 2 labios son generalmente de color blanco a blanco-violáceo. El conectivo de las anteras de los estambres lleva un apéndice, bífido, de unos 1,5mm de largo y las anteras propiamente dichas pueden llevar un acumen apical más o menos digitado.[3][4]
Crece en matorrales subalpinos espesos y en monte bajos, frecuentemente como sotobosque de Eucalyptus pauciflora, sobre suelos rocosos graníticos.[3]
Prostanthera cuneata fue descrita, sin figurar, por George Bentham y publicado en Prodromus Systematis Naturalis Regni Vegetabilis, de Alphonse Pyrame de Candolle, vol. 12, p. 560, n.º 9, en el año 1848[1].[5][1]
