“…The new counts are mostly somatic numbers, determined on root-tip material, using 130 minutes of pre-fixation treatment with saturated aqueous p-dichlorobenzene and staining with alcoholic carmine (Snow 1963). Plants transplanted from the wild were grown at the Royal Botanic Gardens Sydney.…”

New records of chromosome numbers are presented for eleven Australian species of Veronica sens. lat. Reference is also given to records previously published for ten species that have been referred to Derwentia, Parahebe or Chionohebe, but that are now included in a widely circumscribed Veronica. The species formerly included in Derwentia, Parahebe or Chionohebe exhibit secondary base numbers of x = 21, 20 or 19, whereas those formerly retained in Veronica have x = 18 (or 17). For the species formerly referred to Detzneria, from New Guinea, we present only a very approximate count of 2n = 38-42 which, however, differs from the previous report of 2n = 48.

Meiosis of triploid Lolium. II. Discrepancies between the analyses of chromosome configurations at metaphase I in inverse autoallotriploid combinations

Chromosome configurations were analysed at metaphase I in six plants of each of the two inverse autoallotriploid types of Lolium temulentum x L. multiflorum with the genome combinations TTM and TMM. In the combination with two large genomes and one small (TTM), there was no preferential pairing but with two small genomes and one large (TMM) there was preferential pairing. The findings are discussed in relation to the differences in DNA amounts of the two species and the associated differences in meiotic times of larger and smaller genomes. The results question the value of pairing data in triploids for the assessment of the relatedness of diploid species.

A study of chromosome association and chiasma formation in the amphidiploid between Lolium multiflorum and Festuca drymeja

The chromosomes of Festuca drymeja are larger than those of Lolium multifiorum and the two complements can be distinguished in the F1 hybrid and allotetraploid. Chromosome associations at metaphase 1 in the amphidiploid was typical of an allopolyploid because all the bivalents were symmetrical, which indicates complete preferential homologous chromosome pairing. Chromosome behaviour within the two genomes of the amphidiploid differed from that in the corresponding diploid species. The mean chiasmata per bivalent of the F drymeja complement was much higher in the allotetraploid than in the diploid species and there was a corresponding reduction in the L. multifiorum complement compared with the diploid. Total chiasma frequency of the amphidiploid was determined by the additive effect of the two genomes but there is evidence that the distribution of chiasmata was related to the specific genomes.
