Faimilies

The order is a cosmopolite (plants foond throughoot maist o the warld includin desert an frigid zones), an includes maistly yerbaceous species, altho a smaa nummer o trees (sic as the giant Lobelia an the giant Senecio) an shrubs are an aa present.

Asterales are organisms that seem tae hae evolved frae ane common auncestor. Asterales share characteristics on morphological an biochemical levels. Synapomorphies (a character that is shared bi twa or mair groups throu evolutionary development) include the presence in the plants o oligosaccharide inulin, a nutrient storage molecule uised insteid o starch; an unique stamen morphology. The stamens are uisually foond aroond the style, aither aggregatit densely or fused intae a tube, probably an adaptation in association wi the plunger (brush; or seicontar) pollination that is common amang the faimilies o the order, whaurin pollen is collecit an stored on the lenth o the pistil.
