Aster or Erigeron?

It can often be difficult to distinguish between these two genera, especially on the basis of a single, general shot, as above - though helpfully, this one shows habitat, habit, upper surface of flower-heads and upper surface of leaves (albeit not in close-up detail). The individual species often vary considerably, making it quite a challenge to arrive at a reliable name. A common plant is Aster flaccidus but this normally has undulate margins to its leaves; there are a number of Erigerons to consider.

PLEASE, each time you post, provide an approximate elevation (exact not necessary), approximate location in terms of nearest village, pass, lake or whatever and DO ALSO photograph the leaves (foliage) as well as flowers - otherwise it can be IMPOSSIBLE to arrive at a definite identification. Ideally, take SEVERAL photos per specimen showing flowers (front and underneath), foliage (top surface and underneath), habitat shot and habit of plant - I realise this requires greater effort but once a methodical approach is adopted, it is straightforward to do and does not take that long (though hard-going at extreme elevations.....but having taken the time, effort and expense to get to these lovely places, worth getting the most out of it and helping the study of Pakistan flora); nowadays with digital cameras and small memory cards (which can accept large numbers of images) and small batteries, this can readily be done. When I began exploring the Himalaya in the 1980s, one used slide-film, which was expensive, so only 1 or 2 photos could be taken per plant and a tripod plus macro-lens was needed for close-up images of flowers. That has all changed. If anyone reading this is heading to the Himalaya in the coming years and would welcome further advice about securing a good set of images of the flora seen (sufficient to enable me to provide identifications), do get in touch.
