Hemiphora is a genus of five species of flowering plants in the mint family, Lamiaceae and is endemic to Western Australia. Plants in this genus are woolly shrubs with warty, hairy leaves and with five petals joined to form a tube-shaped flower with four stamens. These species are similar to those in the genus Chloanthes in that the base of the leaves extends down the stem. They differ from Chloanthes, in that the leaves only extend a short distance down the stem.
Plants in the genus Hemiphora are evergreen shrubs which have their stems, leaves and parts of their flowers densely covered with woolly hairs. The leaves are simple and are arranged in opposite pairs or in whorls of three, covered with woolly hairs and small blisters. The leaves appear narrow because their edges are turned under, so that the lower surface of the leaf is not visible. The flowers are arranged singly in leaf axils and are surrounded by leaf-like bracts and two bracteoles. Flowers have five sepals which are joined at their base to form a very short tube with five lobes. The five petals are joined to form a curved tube with five lobes, the lower lobe roughly triangular in shape, the two side lobes and the upper two all similar in size and shape. There are four stamens sometimes with the lower pair shorter than the upper ones or sterile.[2][3][4]
In 1876, Ferdinand von Mueller described Chloanthes elderi and placed it in the section Chloanthes sect. Hemiphora.[5] In 1882, Mueller raised Hemiphora to genus so that Hemiphora elderi became the type species of the new genus.[1][6] In 2011, Barry Conn, Murray Henwood and Nicola Streiber transferred four species, previously in the genus Pityrodia into Hemiphora.[2]
All species of Hemiphora are endemic to Western Australia.[3]

Hemiphora es un género de plantas con flores de la familia de las lamiáceas. En su aceptación actual ampliada, incluye 5 especies aceptadas;[1] previamente, el género era considerado monoespecífico, con Hemiphora elderi como única especie.[2][3] Es estrictamente endémico de Australia occidental (Estado de Western Australia).[4]
Son matas perennes de poca altura (unos 50cm), densamente peludo-lanosas con pelos dendroides, de tallo erecto ramificado con hojas simples, densamente peludas, enteras o serradas, sésiles y algo decurrentes, opuestas o decusadas o en verticilos de 3, pudiendo parecer estrechas por el borde fuertemente revoluto, de haces rugosas o con hinchazones. Las flores son axilares y solitarias, zigomórficas, hermafroditas, bibracteoladas, con el cáliz profundamnete pentalobulado y de tubo corto, mientras la corola es bilabiada, pentamera, con tubo largo, curvado y distalmente dilatado y con el labio superior bilobulado y el inferior trilobulado. Hay 4 estambres, implantados en la mitad inferior del tubo de la corola, todos fértiles o los 2 inferiores reducidos a estaminodios; el conectivo carece de apéndices o son inconspicuos. El fruto es seco, indehiscente o dividido en 2 mericarpos con semillas dilatadas multirepliegadas.[5][6][2]
El género ha sido establecido por Ferdinand von Mueller y publicado en Systematic Census of Australian Plants, p. 103 en 1883,[1].[7]y que había anteriormente descrito, como Chloanthes elderi de especie tipo, en Fragmenta phytographiæ Australiæ, 1876, p. 13[2]. La especie tipo es Hemiphora elderi F.Muell. (F.Muell.), especie que se consideró durante tiempo como la única del género.[2][3]
Hemiphora, vocablo construido con el griego ήμί, medio, mitad y φορά, tener, soportar, llevar; o sea «que lleva la mitad»,[9] pues el género, cuando se estableció, contaba con una única especie, H. elderi, que tiene solo 2 estambres fértiles y los otros 2 reducidos a estaminodios.Comparable a la etimología, similar, de otros 2 géneros de la familia: Hemigenia y Hemiandra.
