The capacity for population increase of H. latifolia is high with the contribution from disc achenes usually considerably more important than that of ray achenes. Plants derived from ray achenes will contribute more, relative to those derived from disc achenes, in declining populations or populations in which disturbance reduces the survival of the growth stage more than the survival of the dormant seed stage.-from Authors
