>From what I understand about Asteraceae, more than 90 percent plants are
herbs, shrubs and trees may not contribute more than 5-10 percent species.
I propose that let members take the simple way out. Looking at the heads,
let them differentiate whether petals (truly petal-like ray florets) can be
seen or not, of not they would fit into group Discoideae; if members can
see ray florets (petals for non botanists), they can judge whether all are
similar (only ray florets) to fall under Liguliflorae, or there are ray
florets (petals) on periphery and differently coloured discs in the centre,
to fall in Radiatae.
I think this simple guidance, plus a list of genera covered under each
group (as suggested by Dinesh ji) should help members arranging their
photographs.
Your suggestions please for making uploads as simple as possible in this
large family.
If we find a particular group too large, we can always further split on the
basis of yellow vs non yellow heads, a feature used in many floras.
