The common dandelion is actually a microspecies
and there are a number of other dandelion species, so identification can be tricky.
Ugent (1970a) grouped all these 'microspecies
' into the 'Solarium brevicaule complex' and proposed continuing hybridization of cultivated species with yet another wild species outside the complex (S.
Yet, quantitative studies of variation in agamospermous grasses give little evidence of microspecies
formation (Usberti and Jain, 1978; Ishimitsu and Tateoka, 1983; Helgadottir and Snaydon, 1986; Kellogg, 1990).
Ecological differentiation of the microspecies
Salicornia dolichostachya Moss and Salicornia ramosissima J.
The first three mechanisms produce highly variable arrays of clonal or uniparental microspecies
. Sexual reproduction among microspecies
is limited, reducing their relevance to discussions of sexual isolation and speciation.
