Explanation of Abbreviations and Signs.

1. Plants marked thus ° (e.g., °Melicytus micranthus) in the list are those that I have not collected myself or seen in the collections of others, but are introduced on the evidence of previous collectors. It may perhaps be noted that Raoul's list has been very carefully drawn up, and is throughout reliable. Though the identifications of Mr. J. F. Armstrong's list may not always be correct, still some plant can generally be found which the name represents; but in J. B. Armstrong's list there are names of many species which obviously do not occur on Banks Peninsula. Some of these can at once be rejected on external evidence, but in other cases it is manifestly impossible to say that the plant has not been found on the peninsula, though its occurrence there may be highly improbable. It is included in my list if there is any subsidiary evidence to suggest that it may have become extinct or have been overlooked. These species inquirendae are marked with a small (¹) before the initial letter of the genus—e.g., (¹)Eleocharis Cunninghamii. This is intended to indicate that there is some reason to believe that the plant occurs or has occurred on the peninsula, but that it has not been recently found. Similarly the species excludendae—those plants which, though recorded, probably have not been found on the peninsula, or which have been identified in error—are marked with a small (²) before the initial letter of the genus — e.g., (²)Fimbristylis fiondosa. Of course, the line between species inquirendae and species excludendae is often very indistinct. It is quite possible that some of the species excludendae may subsequently be found on the peninsula, but the evidence in their favour does not justify their inclusion at present. Should they be discovered they can be readily reinstated. Of the species inquirendae, some are included in my list, and others, where perhaps the evidence for their occurrence is somewhat weaker, are only noted. In any count of the list, of course, only those which are definitely included should be reckoned.

2. Plants whose names are preceded by an asterisk, thus, *Asperella gracilis, have not been found on the Lyttelton Hills—i.e., between Gebbie's Pass and Lyttelton North Head. Plants not so marked are to be found or have in the past been found on the Lyttelton Hills. Some are perhaps now extinct there. It will also be noted that some plants recorded from the Lyttelton Hills are not recorded from Banks Peninsula; this in the majority of cases is probably due to the fact that the district nearer Christchurch has been more exhaustively examined than the more remote one. This, however, is not always the case, for Senecio saxifragoides and Myosotis australis var. seem to be confined to the smaller district.
