Chromosome Numbers in Some Pacific Pteridophyta G Chromosome Numbers in Some Pacific Pteridophyta G. BROWNLIE1 ABSTRACT: Haploid chromosome complements are recorded for two species of Psilotaceae, and for 36 species and one variety of ferns (27 species from New Caledonia, 7 species and 1 variety from New Zealand, and 1 species from N ew Guinea ). It is suggested that Schizaea fistulosa Labill , and Schizaea fistulosa var. australis Gaud. are specifically distinct. A further suggestion is made that the cytologically varied species of Lindsaea together with such genera as Loxsoma and Leptolepia may constitute a distinct fern family. THE VALUE OF CYTOLOGICAL RECORDS of the NOTES ON CRITICAL GENERA type listed below lies in the contributions they Schizaea can make to an understanding of relationships within groups of plants. Information such as Records of chromosome counts in this genus this complements earlier morphological work, are few ( Lovis, 1958; Brownlie, 1%1) but and can be used only in conjunction with such these bear OUt the generally held belief that records, for it is in itself merely another morph­ the present species are relics only of an old ological criterion.

  • Plant Life of Western Australia
    INTRODUCTION The characteristic features of the vegetation of Australia I. General Physiography At present the animals and plants of Australia are isolated from the rest of the world, except by way of the Torres Straits to New Guinea and southeast Asia. Even here adverse climatic conditions restrict or make it impossible for migration. Over a long period this isolation has meant that even what was common to the floras of the southern Asiatic Archipelago and Australia has become restricted to small areas. This resulted in an ever increasing divergence. As a consequence, Australia is a true island continent, with its own peculiar flora and fauna. As in southern Africa, Australia is largely an extensive plateau, although at a lower elevation. As in Africa too, the plateau increases gradually in height towards the east, culminating in a high ridge from which the land then drops steeply to a narrow coastal plain crossed by short rivers. On the west coast the plateau is only 00-00 m in height but there is usually an abrupt descent to the narrow coastal region. The plateau drops towards the center, and the major rivers flow into this depression. Fed from the high eastern margin of the plateau, these rivers run through low rainfall areas to the sea. While the tropical northern region is characterized by a wet summer and dry win- ter, the actual amount of rain is determined by additional factors. On the mountainous east coast the rainfall is high, while it diminishes with surprising rapidity towards the interior. Thus in New South Wales, the yearly rainfall at the edge of the plateau and the adjacent coast often reaches over 100 cm.

GIUDICE2 Summary: The spores of Schizaea fistulosa from Chile were studied using light microscopy (LM), scanning (SEM) and transmission electron microscopy (TEM). The spores are monolete and elliptic in polar view. The major equatorial diameter is 71-85 µm and the polar diameter is 54-61 µm. The laesurae are 50-60 µm long and, in some cases, bifurcated. The sporoderm ultrastructure is first mentioned and described here. The exospore is two-layered in section, verrucate-tuberculate with single or fused elements forming short ridges. The perispore is single-layered, 10-30 nm thick and it is only visible under transmission electron microscopy. On the spore surface, numerous, single or fused, spheroids and nanospheroids of different sizes were observed attached to the perispore surface. The results are discussed and compared with previous studies in Schizaea. Key words: Schizaeaceae, Schizaea fistulosa, spores, morphology, ultrastructure.

Adansonia, sér. 3, 36 (1): 21-43. http://dx.doi. org/10.5252/a2014n1a3 ABSTRACT A colony of a fern, Lygodium hians E.Fournier (Schizaeales), studied on the southwest Pacific Island of New Caledonia, displays a growth form unusual for any member of this genus. Other living species of the genus Lygodium Sw. are characterized by twining fronds, with indefinite growth, which climb extensively on the support provided by other nearby vegetation. These fronds can arise from as early as the sporeling stage and fulfil both vegetative and reproductive functions, with spores produced in lateral sorophores in the upper parts of the fronds. By contrast, in L. hians, climbing fronds are only rarely produced and these carry terminal to subterminal sorophores.

SMITH University Herbarium, 1001 Valley Life Sciences Bldg. #2465, University of California, Berkeley, California 94720-2465, U.S.A. Key words: pteridophytes, floristics, phylogenetics ABSTRACT The status of floristic work on pteridophytes around the world is reviewed. Relatively modern floras exist for most temperate and Mediterranean areas, including Europe, the former Soviet Union, North America north of Mexico, Chile, South Africa, and Australia, but are absent, partial, or outdated for many, if not most, tropical and subtropical countries/regions. Exceptions in the New World include Mexico, Mesoamerica, and certain of the Antilles. For many areas we have only annotated checklists (e.g., Tropical East Africa, Malaysia, Mount Kinabalu) or partially written floras (Ecuador, Malesia). Modern treatments for island floras are also few, exceptions being for New Zealand (Brownsey & Smith-Dodsworth, 2001), Hawaii (Palmer, 2003), and the Mariana Islands (Raulerson & Rinehart, 1992). Floristic “hotspots”, e.g., Colombia, Brazil, Madagascar, New Guinea, and the Himalayas, often have inadequate or incomplete modern accounts. Treatments of the ferns are planned or in progress for many countries, including Venezuela, Bolivia, East Africa, and China, but these often proceed at a painstakingly slow pace.
