This species has nearly all the floral characters of 7. amabile, except that the flowers 
are large and the calyx-lobes relatively longer; but it is altogether a more robust 
plant, witiph large leaves and numerous distinctly stalked flowers in each head or umbel. 
Possibly it; may be only a vigorous state of 7. amabile.
