Floral Structure, Breeding System and Fruit‐set in the Threatened Sub‐shrub Tetratheca juncea Smith (Tremandraceae)

Reproductive ecology of Tetratheca juncea

Concern for pollinator decline has become a global issue. Gross et al. (pp. 771-777) investigate fecundity levels in the threatened shrub Tetratheca juncea, a species that has undergone a major range contraction in the last 200 years. The species is facultatively outcrossing with flowers presented for buzz pollinators. Across populations fruit-set varied widely and the pollinators were elusive, a feature common in Tetratheca.
