Discussion

Over its extensive range, Phemeranthus parviflorus varies considerably in several characters, including overall size. Although this variation is more or less continuous, correlating very generally with habitat type and geographic location, some populations that are found toward the limits of the species’ range and that exhibit combinations of tendencies to extremes in the variable characters have been recognized separately. The Alabama populations, few and confined to a very small area on gneiss in the central part of the state, disjunct from the main trans-Mississippi distribution of P. parviflorus, with elongate stems, small flowers, and stigmas often three-lobed, or three instead of one, have been described as Talinum appalachianum. Plants from Arizona with stems slender and tending to elongate, sepals acuminate-cornate and usually purplish, and capsules ovoid have been described as T. gooddingii. Plants from the mountains of New Mexico with elongate stems, subsessile flowers, markedly congested cymes, and acuminate, often persistent sepals have been described as T. confertiflorum (P. confertiflorus).

Reports of Phemeranthus brevifolius from western Texas and southern New Mexico, where it does not actually occur, apparently have been based on misidentified specimens of P. brevicaulis.
