Flowering Ecology of the Species of the Genus Hypoxidia (Hypoxidaceae: Asparagales) [PDF]

open access: yesJournal of Botany, 2011
Hypoxidia (Hypoxidaceae) is endemic to the Seychelles islands. The two species H. rhizophylla and H. maheensis have rarely been studied. The first studies of floral ecology are described based on 19 years of observations of cultivated (1992–1994) and wild (1998–2011) plants of H. rhizophylla and a single flowering event of cultivated H. maheensis. In H.
