Pityrodia is a genus of flowering plants in the mint family, Lamiaceae and is endemic to Australia, most species occurring in Western Australia, a few in the Northern Territory and one in Queensland. Plants in this genus are shrubs with five petals joined to form a tube-shaped flower with four stamens of unequal lengths.
Plants in the genus Pityrodia are evergreen shrubs with erect, usually cylindrical branches. The leaves are simple, net-veined and their bases partly wrap around the stem (decurrent). The flowers may occur singly or in groups and exhibit left-right symmetry. There are 5 sepals which are joined at their bases and 5 petals joined to form a tube. The tube may have 5, unequally sized lobes at the tip or two "lips" - the upper lip having two lobes and the lower one three. There are four stamens with one pair longer than the other. The fruit is a drupe containing up to four seeds.[2][3]
The genus was first described by Robert Brown in 1810. Brown published his description in Prodromus Florae Novae Hollandiae and designated Pityrodia salvifolia as the type species.[1][4] The name Pityrodia is an Ancient Greek word meaning "scale-like".[5]
Pityrodia was originally included in the Verbenaceae. In a review of the genus in 1979, Ahmad Abid Munir included Pityrodia and nine other genera in a family Chloanthaceae, all endemic to Australia and sometimes referred to as "Australian Verbenaceae".[2] The name Chloanthaceae has not been widely adopted and Pityrodia is now included in the Lamiaceae.[6]
In his 1979 paper, Munir described 27 species from Western Australia, 16 from the Northern Territory and one from Queensland,[2] but in 2011, Barry Conn, Murray Henwood and Nicola Streiber transferred some species to Dasymalla, Hemiphora and Quoya and raised a new genus Muniria to which four species of the former Pityrodia were transferred.[7] A new species from Western Australia, (Pityrodia iphthima) has since been described.[6]

Pityrodia es un género de plantas con flores con 20 especies aceptadas pertenecientes a la familia de las lamiáceas.[1]Es un endemismo de Australia, esencialmente del suroeste (Western Australia).[2]
Se trata de arbusto o subarbustos perennes, no aromáticos, con ramitas de sección más o menos redondeadas y con indumento de pelos dendroides/ramificados o escamosa, indumento también presente en las hojas que son opuestas y decusadas, pecioladas o subsésiles a sésiles pero no decurrentes, o en verticilos de 3-4, con limbo de bordes poco a nada revolutos. La inflorescencia es muy variable, con flores bibracteoladas, zigomorfas y hermafroditas. Tienen el cáliz pentalobulado con los lóbulos, romos, del mismo tamaño, persistente pero no acrescente en la fructificación, más corto que la corola; esta última, interior y exteriormente peluda, es más o menos bilabiada con el labio superior bilobulado y el inferior trilobulado. El androceo tiene 4 estambres todos fértiles, mientras el ovario es peludo y más bien liso y deriva en un fruto drupáceo seco, dehiscente en 2 mericarpos biloculares -con 1 semilla por lóculo- no encerado en el cáliz persistente.[5][6][4][7]
El género ha sido descrito originalmente por Robert Brown y publicado en Prodromus Florae Novae Hollandiae et Insulae Van Diemen, p. 513, 1810, con Pityrodia salvifolia como especie tipo[1] que, en la clasificación revisada reciente, entra en el género Pityrodia stricto sensu.

Nota: Recientes estudios citológicos conducen a desmembrar el antiguo género Pityrodia, por polifilético, y a readmitir como válidos los géneros Dasymalla Endl. y Quoya Gaudich. cuyas especies estaban enbglobadas en el género y, por otra parte, el género Hemiphora F.Muell. se extiende para incluir ciertas especies antes atribuidas a Pityrodia. También se crea el género nuevo Muniria N.Streiber & B.J.Conn con 4 especies anteriormente incluidas también en Pityrodia. Este artículo toma en cuenta estos recientes cambios y se refiere, entonces, al género Pityrodia s.s. .Pityrodia é um gênero botânico da família Lamiaceae
