GenusPimelea(Thymelaeaceae) in New Zealand 5. The taxonomic treatment of five endemic species with both adaxial and abaxial leaf hair

Abstract

New Zealand Pimelea species with hair cover on both adaxial and abaxial leaf surfaces include three established taxa that are redescribed and, where necessary, typified. Pimelea sericeovillosa is a cushion plant (three subspecies sericeovillosa, pulvinaris and alta). Pimelea aridula, with two subspecies (aridula and oliga) and Pimelea concinna are medium-sized, erect shrubs. All live inland in the South Island mountains. Pimelea barbata is a scarce, procumbent new species (two subspecies barbata and omoia) and Pimelea mimosa is a rare procumbent to decumbent new species that may be extinct in the wild. Both are from hill country in the eastern North Island. Hybrids and conservation needs are considered. An identification key is presented for all hairyleaved Pimelea species in New Zealand. Relationships with the Australian Pimelea flora are discussed, including evidence for Late Tertiary migration of the genus to New Zealand.

“…The Pimelea genus Banks & Sol.ex Gaertn., encompassing small shrub and forb species commonly known as rice flowers, is indigenous to Australia, Lord Howe Island, New Zealand, and the island of Timor. A thorough exploration based on herbarium records and diverse botanical studies has unveiled a total of 140 distinct Pimelea species [1]. Among these, four species, viz., P. simplex F. Muell.…”

Pimelea leiophylla (Thymelaeaceae): a new endemic species from Tasmania's east coast

“…ex Gaertn. consists of approximately 125 species (Rye 1990(Rye , 1999Copeland & Telford 2006;Burrows 2011). Of these species, 90 are endemic to Australia (Rye 1990(Rye ,1999Copeland & Telford 2006) and a further 35 species occur in New Zealand (Burrows 2011).…”

“…Rye (1999) later suggested that the boundaries of the proposed sections are unresolved and require work, particularly with addressing the placement of the New Zealand species. Burrows (2008Burrows ( , 2011 agreed, noting that some New Zealand species of Pimelea do not fit well with Rye's infrageneric classification, and as such it was not adopted for the species occurring in New Zealand. Instead, the New Zealand taxa were informally divided into two groups: those with leaf hair and those without (Burrows 2008).…”
