Resolving species complexes among taramea, speargrasses, Aciphylla (Apiaceae) using ddRADseq.

Leon Perrie (Museum of New Zealand Te Papa Tongarewa); Lara Shepherd (Museum of New Zealand Te Papa Tongarewa). The 40 species of Aciphylla endemic to New Zealand make it one of the country’s biggest indigenous genera.  In the Apiaceae, the colloquial name of speargrasses reflects that the leaflets of most species have sharp, stiff, skin-piercing apices with the …
