A new species of Salicornia (Chenopodiaceae) from European Russia

摘要

Salicornia heterantha is described as a new species from the Rostov province in SE European Russia. It differs from other species of Salicornia by (1) the central flower of the dichasia being fused to the main axis of the spike, and (2) the comparatively long anthers in combination with short inflorescences. Only two localized populations are known, from saline clays on the banks of a salt lake. S. heterantha shows a peculiar heterocarpy: fruits of lateral flowers are dispersed freely while the fruit of the central flower remains fixed to the spike.
