| Extrorse anthers are somewhat concentrated in primitive dicots and primitive monocots and are rare in more advanced groups. |
| Such herbaceous monocots are envisaged as evolving in the relatively uniform environment of the moist tropics. |
| A wide range of monocots produce bulbs of modified leaves which store food over the winter. |
| For example, thale cress and rice are model species for dicots and monocots, respectively. |
| Many proteins with similar properties have since been isolated from tobacco and other plant species, both dicots and monocots. |
| The known flora consists of 41 ferns and fern allies, 3 gymnosperms, 291 monocots, and 516 dicots. |
