  2. 2. Mimosoideae<br />Consists of herbs, shrubs, trees, or vines, with spines sometimes present<br />
  3. 3. Roots<br />Sometimes have a symbiotic association with nitrogen-fixing bacteria, which induce formation of root nodules<br />
  4. 4. Leaves<br />Usually compound<br /> - pinnate, bipinnate, trifoliolate, rarely palmate<br />sometimes simple or unifoliolate<br />usually spiral <br />basal pulvini often present<br />leaflet folding responses (e.g., Mimosa spp.)<br />Generally stipulate, sometimes stipellate<br />
  5. 5. Flowers<br /><ul><li>Actinomorphic/ Radial
  6. 6. bisexual, sometimes unisexual
  7. 7. Corolla</li></ul> - typically 5<br />- distinct petals<br />-basally fused petals (valvate in bud)<br /><ul><li>Hypanthium sometimes present</li></li></ul><li>Inflorescence<br />Variable, typically bracteate<br />
  8. 8. Fruit<br />Generally a legume<br />sometimes indehiscent, winged (samara), drupe-like or divided into transverse partitions (loment)<br />
  9. 9. Anther<br />Longitudinal, rarely poricidal in dehiscence<br />
  10. 10. Gynoecium<br />Unicarpellous<br />Superior ovary<br />1 (rarely 2 or more) carpel<br />1 locule<br />Style and stigma are solitary<br />Marginal placentation<br />Ovules are anatropous, bitegmic<br />Nectaries often present <br />
  11. 11. Androecium<br />Stamens are numerous, distinct and basally fused<br />
  12. 12. Mimosa Pudica<br />also known as Makahiya,<br /> Sensitive plant, or <br />Touch-me-not<br />Leaves bipinnately<br /> compound, with 1 or 2 <br />pinnaepairs, 10-26 <br /> leaflets per pinna<br />Pedunculatepale pink or purple flower heads arise from leaf axils<br />
  13. 13. Mimosa Pudica<br />fruit consists of clusters of <br /> 2-8 pods, which break <br /> into 2-5 segments and <br /> contain pale brown <br /> seeds<br /><ul><li>-flowers pollinated by </li></ul> wind and insects<br /><ul><li>seeds have hard seed coats which restrict germination</li>
