A Preliminary Catalogue of New Zealand Plants Cultivated in Britain. By Professor A. Wall, Canterbury College, Christchurch. [Read before the Philosophical Institute of Canterbury, 3rd April, 1929; received by Editor, 23rd April, 1929; issued separately, 30th November, 1929.] For convenience of reference the plants are grouped in genera, in alphabetical order, and the species within each genus are also in this order. Attention is concentrated upon those plants which are grown in the open. A preliminary attempt has been made to make the list of such plants exhaustive, but the plants grown in houses are certainly not all included here. New things are constantly coming in and new arrivals may or may not succeed, so that no list of this kind can be quite certainly completely comprehensive. The references to all plants grown at Kew are given on the authority of the published hand-lists and some of these plants have not been actually seen by myself. A note of interrogation is added whenever I have had reason to doubt the accuracy of the determination, whether my own or that of others. I shall be greatly obliged to growers into whose hands this list may come for any information about plants which have been overlooked here.
