Sonchus kirkii, also known as New Zealand sow thistle, or shore puha is a herb in the Asteraceae family. [3] It grows in coastal New Zealand. [4]

Contents

Appearance

The shore puha has green leaves extending upwards with spiky sides. On the top is a yellow flower. The shore puha can grow up to 15-30 centimeters tall. Occasionally it grows up to 100 centimeters. [5]

Conservation status

The conservation status of the shore puha is currently at "declining" and its umbrella category is "at risk". [3]

Threats

Other species of weeds that grow faster may be the reason for the shore puha to be at a declining status as it is outcompeted. The sowthistles Sonchus asper and Sonchus oleraceus can take over the habitats that the shore puha prefer and colonizing the area quicker. Up until the mid-1980s the shore puha was common, but since then its numbers have been declining. [3]

Kirk first observed P. kirkii on Great Barrier Island. It was described by Joseph Dalton Hooker from material collected by Thomas Kirk, possibly from the Thames Goldfields, and published in 1869. The initial brief description titled Pittosporum n. sp.? by Thomas Kirk was published in his paper on Great Barrier Island in 1868. This description along with herbarium specimens were sent to Dr. J. D Hooker at Kew Gardens in 1868, and he collaborated to name it after T. Kirk, by giving it the specific epithet kirkii within the publication that was otherwise written by Kirk.
