Forstera
''Forstera'' is a genus of small perennial plants in the Stylidiaceae family named in honour of the German naturalists Johann Reinhold Forster and his son, Georg Forster, who had previously described ''Forsteras sister genus, ''Phyllachne'' just five years earlier. It comprises five species that are endemic to New Zealand with the exception of ''F. bellidifolia'', which is endemic to Tasmania. The species in this genus resemble those in a subgenus of the related genus ''Stylidium'' called ''Forsteropsis'', but they are more closely related to the genus ''Phyllachne''. Proposals to merge the two genera based on information from cladistic analysis have emerged because of these genera's morphological similarities and evidence that they are paraphyletic. == Description == The species in ''Forstera'' are generally erect or decumbent perennials with small imbricate leaves and pedicellate, actinomorphic flowers.〔Good, R. (1925). (On the geographical distribution of the Stylidiaceae ). ''New Phytologist'', 24(4): 225-240.〕 ''Forstera'' and its closely allied sister genus ''Phyllachne'' have often been regarded as the most plesiomorphic genera in their family. Characteristics that this genus shares with ''Phyllachne'' include apically fused thecae that form a single-celled curved anther and the epigynous nectaries. ''Forstera'' can be distinguished from ''Phyllachne'' by its long peduncle (absent in ''Phyllachne'') and the cushion plant habit of ''Phyllachne''.〔Laurent, N., Bremer, B., Bremer, K. (1998). Phylogeny and generic interrelationships of the Stylidiaceae (Asterales), with a possible extreme case of floral paedomorphosis. ''Systematic Botany'', 23(3): 289-304.〕
