During a collecting trip by the authors in June of 2001 throughout northern Queensland, two species were found, the Laurasian Nowellia curvifolia (Dicks.) Mitt. from the cloud forest of Bellenden Kerr summit and the Malesian-Australasian Nowellia langii Pears. from the montane forests of Cardwell Range.IntroductionThe authors, within the framework of Flora of Australia project, visited the mountain ranges of northern Queensland, between 9 and 20 June 2001. The ma-in object of the trip was to collect material for the revision of the Australian spe-cies of Frullania, but abundant collections were also made of other liverworts and some mosses. The collecting trip was sponsored by the Australian Biological Resources Study Participatory Program and supported by the Natio-Acta Biologica Plantarum Agriensis 2: 201222nal Herbarium of New South Wales, Royal Botanic Gardens Sydney (NSW), by the James Cook University, School of Marine and Tropical Biology, Townsville (JCU) and by the Cryptogam section of the Australian National Herbarium, Canberra (CANB). ResultsDuring the trip two species of Nowellia Mitt. were found in two different localities. As the genus is thoroughly revised by Grolle (1968), it was easy to identify them, asNowellia curvifolia (Dicks.) Mitt. (Subg.

(CANB, EGR, BRI, NSW).Distribution: It is widespread in the more oceanic parts of the northern temperate belt of eastern Canada and USA, in Eurasia from the Azores and Britain to European Russia and the Caucasus Mts, in the milder climactic coastal parts of Siberia , and in Sakhalin, Korea, Japan, China including Taiwan. It is also found as far south as the higher tropical mountains in Mexico, Venezuela,  Brazil, Sri Lanka, Indonesia, Malaysia and the Philippines (see maps in Grolle (1968), Gradstein & Váňa 1987, distributional data in Chuah-Petiot (2011), Gradstein&Costa(2003),Gradstein&Váňa(1994),Leónet al.

New to Australia.Illustration: Grolle 1968: 42, fig. 8. Map: Grolle 1968: 46, map 2.Pócsetal.:NowelliainAustralia23DiscussionNowellia Mitt. is a peculiar genus within the family  Cephaloziaceae Mig. distinguished by the ventral margin of the bilobed leaf modified into a water-sac. Grolle (1968) in his monograph enumerated 7 species; Robinson (1970) described one more (N. reedii). Out of the 8 species, N. curvifolia is Laurasian, with oceanic boreo-temperate distribution, but penetrating south on tropical mountains. Four of them are Neotropical and three Palaeotropical, with quite restricted Indo-Malesian distributions. None of them were previously known from Australia. It is easy to distinguish the two Australian species from each other, as is demonstrated in the key below (based on Grolle 1968):1. Well-developed leaves at least 10–15 cells high from the leaf insertion to the sinus between the two acute segments of lobe; lobe margins entire. Water-sac large, 16–20 cells wide, inflated only in the lower half. Stem with 8–12medullarycells.………………………….. Nowellia curvifolia2. Well-developed leaves only 4–6 cells high from the leaf insertion to the si-nus between the two acute segments of lobe, lobe margins with long ciliae. Water-sac small, only 6–10 cells wide and fully inflated. Stem with 3–6medullarycells.…….……......................................... Nowellia langiiIt is phytogeographically interesting that the distribution of the two species overlapsatthejunctionofLaurasiaandGondwana.GradsteinandVáňa(1987)discussed the penetration of Laurasian elements into Gondwana, citing Nowellia curvifolia as a typical example. The new Australian locality is one of the southernmost occurrences in the world.
