Rumex skottsbergii

Rumex skottsbergii, or more commonly known as lava dock,[1] is a shrub of the genus Rumex. The genus comprises approximately 200 species all derived from a single species and are therefore monophyletic.[2] Furthermore, Rumex skottsbergii is endemic to Hawaii, where it is known as pāwale. Pāwale are commonly found in open lava fields that are at low elevations which range from 460-1300m.[3][4] A similar plant in this genus is Rumex giganteus. Their similarity lies between their erect nature and leaves. However, the difference lies in their inflorescences.[2] The inflorescences is described as being a cluster of flowers from the main stem axis .[5]

Rumex skottsbergii can be identified through their green, narrow, compact inflorescences, erect nature and small leaves. Their stems are usually stiffly erect with 7-10dm long and glabrous.[2] Rumex skottsbergii can also be identified through their unisexual flowers and medium-sized yellowish greenish branched inflorescences; their outer tepals are also a distinguishable trait found within this genus.[2]

Distribution

Rumex skottsbergii are found in Hawaii and are species that flourish in low elevation and open lava fields.[2]

Uses

Rumex skottsbergii was used for medicinal purposes and was used to treat a childhood's diseases known as pāʻaoʻao and constipation. The childhood disease would cause physical weakening.[6]
