Alternanthera nahui |
Alternanthera nahui, common name nahui,[3] is a species in the family Amaranthaceae, native to New Zealand and to Norfolk Island.[1]
It is a perennial herb that has a slender tap root. Its stems are 1.5–3.0 mm in diameter and tend to lie down.[3] It can be distinguished from Alternanthera sessilis by its narrower leaves, its keeled tepals, its shorter staminodes and style.[3]
It was first described in 2009 by Peter Heenan, Peter de Lange and J. Keeling.[1][2]
There are no synonyms according to Plants of the World Online.[1] However, according to NZPCN it has, from time to time, been incorrectly referred as Alternanthera sessilis (L.) Roem. & Schult.[3]
It is a coastal and lowland species found in both seasonally and permanently wet habitats.[3]
In the 2018 conservation assessment of de Lange and others under the New Zealand Threat Classification System it was classed as "Not Threatened", having a "large, stable population".[4]
