Flora of New Zealand Series

CHROMOSOME NUMBERS

SPECIES

The arrangement is as follows:

a. Gymnosperms

b. Dicotyledons

c. Monocotyledons

The families` within these three major plant groups are arranged in alphabetical order; the genera are listed alphabetically within families, the species alphabetically within genera and the varieties alphabetically within species.

The names are arranged under families recognised in the Flora of New Zealand Volume I and II; other than this no taxonomic judgments have been made and the generic and specific names quoted are those given in the work consulted even if these names are not currently used. Authorities are cited for each entry just as they are given in the work consulted. If no authority was given none is entered on our list.

It should be noted that

(1) Only named spp. have been included, i.e. "Leucopogon 11 spp." or "Callitriche n. sp." are omitted.

(2) Genus counts are not included, i.e. "Fuchsia x = 11".

(3) Hybrids are not included.

(4) Horticultural vars are not included.

(5) In general, published counts for any sp. regarded as indigenous to N.Z. are included whether the plants investigated originated in this country or not. Sources of error include.

(a) doubtful identity of N.Z. plants with cosmopolitan spp. where local counts are lacking, e.g. Bidens pilosa

(b) misidentification where counts are based on garden-grown specimens in other countries, e.g. Cordyline australis

(c) ambiguous use of specific epithets where synonymies are complex, e.g. Metrosideros diffusa.

(6) In Hebe and Solanum only counts made by Hair and Baylis respectively are cited, as these counts are related to comprehensive taxonomic revisions.

(7) In Gramineae the only counts cited are those by Hair and Beuzenberg, by Calder and by D. M. Moore, all based directly on plants from the N.Z. Botanical Region.

NUMBERS

Gametic (n) and sporophytic (2n) numbers are quoted just as they are given in the work consulted.

REFERENCES

The full reference to papers quoted here only by author's surname and year may be found in the Annals of Taxonomic Research (Fl. N.Z. Vol. I, 1961, pp. xiii-xxxiv; Vol. II, 1969, pp. xv–xxx).

AUTHORS

(1) N.Z. authors working on N.Z. plants in N.Z.Original papers have been consulted and chromosome counts are cited under the author's name, by surname and year of publication.

Nordenskiöld (Luzula) and Ornduff (Senecio) are treated as N.Z. authors since both worked for some time in N.Z. collecting cytological material. As Macquarie Id is regarded as part of the N.Z. Botanical Region, D. M. Moore's records of plants from there are treated as from N.Z.

(2) Overseas authors

The original papers have not been consulted and counts are quoted as cited in Darlington and Wylie "Chromosome Atlas" 1955 (D. & W.), in Löve and Löve "Chromosome Numbers of Central and Northwest European Plant Species" Op. bot. Soc. bot. Lund Vol. 5, 1961 (L. & L.) and in the "Index to Plant Chromosome Numbers" (IPCN). The latest issue of IPCN used is that for 1967. "IPCN Suppl." without date, refers to a supplement which records counts published in various years previous to 1956.

Overseas authors whose counts are not recorded in D. & W., or in L. & L., or in IPCN are cited here by surname and year. These are marked with an asterisk to distinguish them from N.Z. authors.

ORDER OF CITATION

(1) N.Z. authors and overseas authors quoted by name, are cited first; where there is more than one reference for the same sp. the authors are listed alphabetically, e.g.

Hair 1963: 245

Rattenbury 1957: 938

(2) Counts from D. & W. with page reference, e.g. D. & W.: 19.

(3) Counts from L. & L. with page reference, e.g. L. & L.: 215.

(4) Counts from IPCN, the relevant year and the page being cited, e.g. IPCN 1965: 24.

Each count is cited only once; where original N.Z. papers are quoted the equivalent references from D. & W., L. & L. or IPCN are omitted.
