  • Discussion of what factors would lead to comfort. Knowledge of things about – not necessarily names but being able to observe detail ,note difference and being aware of how plants can differ. Knowledge of anmals, tracks, scats and signs. Skills of survival? Where is north, aspect and vegetation change etc etc .
  • Lect 5 flora identification 2013

    1. 1. OEEDU5003 Connecting with Nature Week five Flora identification.
    2. 2. Ecological literacy • What does it mean to be ecologically literate? • EL is about knowing and being comfortable in a place? • What would make you more comfortable in a place?
    3. 3. Flora Identification Using Costermans’ Trees of Victoria and adjoining areas book
    4. 4. Diagnostic features of plants • List some diagnostic features used to ID plants • Leaves, buds, flowers, fruits, barks, shape, height,… • Observe leaves provided – Identify as many different characteristics as you can
    5. 5. Characteristics of leaves (Costermans, 1998, p. 46) • Vein pattern (lateral, lanceolate, ovate, longitudinal veins, oblique) • Margins – toothed, scalloped, serrated, smooth • Colour – if 2 surfaces different = discolorous • Shape & size • Texture – waxiness (glaucous – bluish-green) • Leaf attachment – opposite or alternate • Attachment to stem – sessile (stalkless, no petiole) • Symmetry or oblique • Glands • Smell (lemon-scented, peppermint)
    6. 6. Characteristics (Costermans, 1998, p. 46) • a. Lateral veins at large angle to midvein (eg, Mahogany, Bloodwood) • b. Long lanceolate leaf (eg, Manna Gum group) • C. Ovate leaf, intra- marginal vein distant from margin (eg, Red Box)
    7. 7. Look closely at the leaves
    8. 8. Characteristics (Costermans, 1998, p. 46) d. Lateral veins at small angle to midvein (eg, narrow-leaved peppermint) e. Lateral veins tend longitudinal (eg, snow gum) f. Leaf broad, curved, asymmetrical, oblique (eg, Messmate)
    9. 9. Juvenile leaves (Costermans, 1998, p. 46)
    10. 10. Buds, Flowers & Fruits (Costermans, 1998, p. 48)
    11. 11. Buds (Costermans, 1998, p. 48)
    12. 12. Flowers (Costermans, 1998, p. 48)
    13. 13. Parts of eucalypt fruits (Costermans, 1998, p. 48)
    14. 14. Barks – see pages viii-ix
    15. 15. Wattles – Pods & Seeds • All wattles form pods • Differences in pods can be helpful for ID. • The seed attachment stalk (funicle) is a good diagnostic feature. • Eg Blackwood, this is red & doubly encircles the seed • Eg Lightwood, it is white & folded at the seed base
    16. 16. Key Groups of Wattles for ID (Costermans, 1998, p. 131) • Adult foliage always bipinnate (‘feathery’), p. 132 • Adult foliage as phyllodes (‘simple leaves’), p. 135 • Flowers in cylindrical spikes, p. 135
    17. 17. Key Groups of Wattles for ID (Costermans, 1998, p. 131) • Flowers in globular heads, p. 138 • Phyllodes one main vein, p. 138 • Phyllodes with more than one main vein, p. 143
    18. 18. Using the Costermans’ Book • Need to know where your patch of bush is located? • What vegetation type? • See pp. 8-9
