GenusPimelea(Thymelaeaceae) in New Zealand 2. The endemicPimelea prostrataandPimelea urvillianaspecies complexes

Abstract

The taxonomy of the glabrousleaved plants ascribed to Pimelea prostrata and P. urvilliana (here each regarded as members of a species complex) is examined. The entities that were originally classed under the names prostrata and urvilliana are identified and the species typified and described.

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

“…The same conceptual approach, terminology and conventions are employed here. As before (Burrows 2008(Burrows , 2009a(Burrows , b, 2011, comparative morphologic criteria are used to discriminate between the taxa. Definition of species was carried out after qualitative and quantitative examination of numerous living and herbarium specimens to develop data sets on many character states.…”

“…Part 2: The genus Pimelea in New Zealand Speciation, character distribution and informal subgeneric groups The current revision of the genus Pimelea in New Zealand (Burrows 2008(Burrows , 2009a(Burrows , b, 2011 reveals that the flora is moderately richly endowed with species (35) and additional subspecies (18). Compared with the Australian Pimelea flora, spread over a much larger land mass (c. 100 species, Rye 1990) this is a relatively high number, but abundant speciation in the genus in New Zealand is paralleled in many others in a variety of families, probably for the same reasons.…”

“…Brief discussion of the evidence for interspecific crossing (as outlined in Burrows 2008Burrows , 2009aBurrows , b, 2011 follows in relation to this.…”

“…It draws on information presented in all five articles of this revision (Burrows 2008(Burrows , 2009a(Burrows , b, 2011 and the current article) and also introduces a limited amount of new but cognate information. Informal groupings of the 35 New Zealand species, based on exclusive occurrences of character states, are noted (Table 3).…”

Taxonomy and conservation of allopatric moth populations: a revisionary study of theNotoreas perornataWalker complex (Lepidoptera: Geometridae: Larentiinae), with special reference to southern New Zealand

“…Many of the Pimelea species have remained undescribed until recently, but revisionary work is currently tackling this group (Burrows 2008(Burrows , 2009a(Burrows , 2009b. This intimate relationship between host and moth constitutes a distinctive element in many New Zealand open habitats from the high alpine to coastal zones including alpine grasslands, montane short tussock grasslands, riverbeds and coastal cliffs.…”
