Many plants are reported from Marlborough for the first time.

26 plants new to the Sounds-Nelson Botanical District are listed.

34 plants new to the North-Eastern Botanical District are listed.

12 plants new to the North-Western Botanical District are listed.

Various additions and subtractions are made in the lists of endemic plants published by Cockayne for the botanical districts of Marlborough in his “Vegetation of Marlborough.”

Attention is drawn to the occurrence almost at sea-level of many species normally subalpine or high montane.

Several hybrids new to the New Zealand Flora are indicated, including the first known occurrence in the genus Haastia.

The delimitation of Botanical Districts in Marlborough is facilitated by the study of “overlap.”

Many plants previously known from a single habitat or thought to have a very restricted distribution are shown to be common or widespread.

Existing records believed to be erroneous are indicated.
