  • TML Propagation Protocols
    PROPAGATION PROTOCOLS This document is intended as a guide for Tamborine Mountain Landcare members who wish to assist our regeneration projects by growing some of the plants needed. It is a work in progress so if you have anything to add to the protocols – for example a different but successful way of propagating and growing a particular plant – then please give it to Julie Lake so she can add it to the document. The idea is that our shared knowledge and experience can become a valuable part of TML's intellectual property as well as a useful source of knowledge for members. As there are many hundreds of plants native to Tamborine Mountain, the protocols list will take a long time to complete, with growing information for each plant added alphabetically as time permits. While the list is being compiled by those members with competence in this field, any TML member with a query about propagating a particular plant can post it on the website for other me mb e r s to answer. To date, only protocols for trees and shrubs have been compiled. Vines and ferns will be added later. Fruiting times given are usual for the species but many rainforest plants flower and fruit opportunistically, according to weather and other conditions unknown to us, thus fruit can be produced at any time of year. Finally, if anyone would like a copy of the protocols, contact Julie on [email protected] and she’ll send you one. ………………….. Growing from seed This is the best method for most plants destined for regeneration projects for it is usually fast, easy and ensures genetic diversity in the regenerated landscape.

  • Multiple Resprouting from Diaspores and Single Cotyledons in the Australian Tropical Tree Species Idiospermum Australiense
    Journal of Tropical Ecology (2002) 18:943–948. With 1 figure. Copyright 2002 Cambridge University Press DOI:10.1017/S0266467402002626 Printed in the United Kingdom SHORT COMMUNICATION Multiple resprouting from diaspores and single cotyledons in the Australian tropical tree species Idiospermum australiense WILL EDWARDS1 and PAUL GADEK School of Tropical Biology, James Cook University, Cairns, Australia 4878 (Accepted 3rd November 2001) KEY WORDS: Idiospermum, large seeds, multiple resprouting In 1999, Dalling & Harms simulated 100% above-ground herbivory on seedlings of Gustavia superba, a large-seeded species from Barro Colorado Island, Panama, and showed the remarkable ability for cotyledons to regenerate up to eight new shoots. They used this evidence to propose that cotyledon size (at least in this species) was adaptive in surviving pre- and early post-germination hazards (Dalling & Harms 1999). In this note we describe the first record of multiple resprouting in an Australian tropical plant species. Idiospermum australiense (Diels) S. T. Blake (Calycanthaceae) exhibits characteristics similar (but not identical) to G. superba that support the contention of Dalling & Harms (1999). Idiospermum australiense is a rare canopy tree species (Briggs & Leigh 1996) that occurs in restricted populations in lowland tropical rain forests in north Queensland, Australia. The species produces the largest dicotyledonary dias- pore in the Australian flora. Fresh diaspores can weigh up to 225 g and com- prise between two and six thick, starchy cotyledons (modal cotyledon number is four) released within an ephemeral, corky seed coat (Worboys 1999). Diasp- ores are gravity dispersed and the seed coat rapidly decays, exposing cotyledons to the immediate environment prior to germination.

  • Primitive Angiosperm Flower – a Discussion*
    Acta Bot. Neerl. 23(4), August 1974, p. 461-471. The structure and function of the primitive Angiosperm flower – a discussion* Gerhard Gottsberger Departamentode Botanica, Faculdade de Ciencias Medicas e Biologicas de Botucatu, Estado de Sao Paulo, Brazil SUMMARY Morphological and functional features of primitive entomophilous Angiosperm flowers are discussed and confronted with modem conceptions onearly Angiosperm differentiation. Evidence is put forward to show that large, solitary and terminally-borne flowers are not most primitive in the Angiosperms, but rather middle-sized ones, groupedinto lateral flower aggregates or inflorescences. It is believed that most primitive, still unspecialized Angiosperm flowers were pollinated casuallyby beetles. Only in a later phase did they graduallybecome adaptedto the more effective but more devastating type of beetle pollination. Together with this specialization, flower enlargment, reduction of inflorescences, numerical increase of stamens and carpels, and their more dense aggregationand flatteningmight have occurred. In have maintained the archaic condi- regard to pollination,many primitive Angiosperms tion of because beetles still dominant insect whereas in cantharophily, are a group, dispersal they have been largely forced to switch over from the archaic saurochory to the more modern modes of dispersal by birds and mammals,since duringthe later Mesozoic the dominance of reptiles had come to an end.

  • 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.

Wood features ofthe family have been summarized by Metcalfe and Chalk (1950); various authors have mentioned one or more traits in studies dealing with Calycanthaceae (e.g., Wilson 1979) or other families (e.g., Garratt 1934). In view of recent interest in Idiospermum australiense (Diels) Blake, a new comparative study is needed. One goal of the present study is clarification of relationships of Idiospermum to Calycanthus and Chimonanthus. Wood anatomy of Idiospermum was described by Blake ( 1972) and Wilson ( 1979); a new description is offered here to provide more quantitative data. De­ scriptions of the wood of Calycanthus and Chimonanthus provided here incorporate such quantitative data, but also modify earlier descriptions with respect to some important qualitative features. Material of the recently de­ scribed genus Sinocalycanthus (Cheng and Chan 1964) was not available, although the description of that genus suggests it is not strongly different from Calycanthus or Chimonanthus. The present study incorporates material of Calycanthus floridus L. var. floridus, C.

  • (OUV) of the Wet Tropics of Queensland World Heritage Area
    Handout 2 Natural Heritage Criteria and the Attributes of Outstanding Universal Value (OUV) of the Wet Tropics of Queensland World Heritage Area The notes that follow were derived by deconstructing the original 1988 nomination document to identify the specific themes and attributes which have been recognised as contributing to the Outstanding Universal Value of the Wet Tropics. The notes also provide brief statements of justification for the specific examples provided in the nomination documentation. Steve Goosem, December 2012 Natural Heritage Criteria: (1) Outstanding examples representing the major stages in the earth’s evolutionary history Values: refers to the surviving taxa that are representative of eight ‘stages’ in the evolutionary history of the earth. Relict species and lineages are the elements of this World Heritage value. Attribute of OUV (a) The Age of the Pteridophytes Significance One of the most significant evolutionary events on this planet was the adaptation in the Palaeozoic Era of plants to life on the land. The earliest known (plant) forms were from the Silurian Period more than 400 million years ago. These were spore-producing plants which reached their greatest development 100 million years later during the Carboniferous Period. This stage of the earth’s evolutionary history, involving the proliferation of club mosses (lycopods) and ferns is commonly described as the Age of the Pteridophytes. The range of primitive relict genera representative of the major and most ancient evolutionary groups of pteridophytes occurring in the Wet Tropics is equalled only in the more extensive New Guinea rainforests that were once continuous with those of the listed area.

Except for the effec's of the weather which are given elsewhere in this report, the year was one of steady and sound development. The building program of the previous year had been completed, and early in 1971 landscaping around the annex was finis3ed and the grounds once again were quiet and serene, suitable for study and contemplation by the thousands of persons who visit the garden each year. Among events which undoubtedly will mark this year in the garden's history are two, especially, which should be mentioned. The botanic garden is a member of the American Association of Museums and durinJ; the year we applied for accreditation by that organization. In August we were notified that we had been granted interim approval until an on-site evalu1tion of the institution could be made by the AAM Accredit1tion Visitin~ Commit­ tee. This visit is expected early in 1972. The second item of interest is that the botanic garden for the first time applied for a plant patent to cover a new hybrid which soon will be released to the horticultural trade.
