au·tog·a·my

(aw-tog'ă-mē),
A form of self-fertilization in which fission of the cell nucleus occurs without division of the cell, the two pronuclei so formed reuniting to form the synkaryon; in other cases, the cell body also divides, but the two daughter cells immediately conjugate.
Synonym(s): automixis
[auto- + G. gamos, marriage]

10B) may have changed from insect pollinated to pure autogamy, but autogamy is not uncommon in this genus, so this failsafe system may even have facilitated establishment of colonizers.
Melampy and Hayworth (1980) suggested that autogamy may have evolved in this species because of the unreliability of insect pollination.
Low pollinator availability due to climate is also the likely factor in the prevalence of autogamy in species (in one case, populations of a species) of Parahebe (Veroniceae) in New Zealand.
