Chromosome studies in some New Zealand and Jamaican bryophytes

Chromosome numbers in some Mosses from New Zealand

“…A recent revision of the family Hypopterygiaceae by Kruijer (2002) has renamed a number of former Hypopterygium species. Newton (1973) Newton (1973) is n=5 and is the same for Australia examined meiotically (Ramsay 1974). The meiotic chromosome number recorded here for Cyathophorum bulbosum from Dunedin (Table 2) had the same chromosome number n=5 and similar bivalents to the Australian collections examined previously.…”

“…Family Bartramiaceae Beever et al (1992) report three species of Philonotis from New Zealand. The mitotic chromosome number of n=6 was recorded for Philonotis tenuis from the South Island by Newton (1973). Previous chromosome records for other species in the genus are (Fritsch 1991, Goldblatt & Johnson 2000 from Europe, India, Japan, Australia, China and Chile.…”

Australian mosses - new chromosome numbers and a compilation of chromosome data

“…In his revision of the genus for Australia, Gilmore (2006) does not mention having examined the specimen of P. harrrisi but when the above collection was compared to specimens of Philonotis tenuis named by Gilmore, it was found to be identical and P. harrisi is thus placed into synonymy with P tenuis. Newton (1973) recorded n=6 from gametophytic mitotic studies of P. tenuis from New Zealand. The chromosome voucher (58/63) named as P. harrisi from Eungella in Queensland in Ramsay (1967aRamsay ( , 1974 has been re-examined and corrected to P. tenuis.…”

“…Both Newton (1973) at mitosis and Ramsay (2009) at meiosis have reported n=5 for New Zealand specimens.…”

“…25) and H. menziesii n=5 (Newton 1973) from gametophytic mitosis from New Zealand. There are no previous reports of mitotic counts in species with the number n=4.…”
