Welcome to Myrcia s.l.
All Neotropical Myrtaceae except Tepualia belong to the exclusively fleshy fruited tribe Myrteae (sensu Wilson et al., 2005). Myrteae can be divided into nine informal groups (Lucas et al., 2007). One of these groups, Myrcia s.l. is defined by its foliaceous cotyledons and soft seed coat combined with bi- or trilocular ovaries containing two ovules and inflorescences usually in panicles. Myrcia s.l. itself can be divided into subgeneric groups (Lucas et al., 2011).
This scratchpad has so far been mostly populated by Chrissy Wilson (college based sandwich student 2011-12) but is in constant development by the Myrtaceae team at RBGKew to gradually classify all accepted species of Myrcia s.l. into one of ten subgeneric sections (Lucas et al., in prep.). The scratchpad currently has an emphasis on the c.110 species of a subgeneric group corresponding to clade 9 of Lucas et al. (2011), or Myrcia sect. Aulomyrcia (O. Berg) Griseb (see Lucas et al., 2016). The scratchpad provides type images and protologues of those species, or links to those available online, in a single place. It is hoped that once publicised it will be a resource used and populated by any interested researcher.
Update - September 2017
Myrcia 'sections' will be published soon and all accepted species have been placed in one of these groups. Only those of 'sect. Aulomyrcia' have images and links. Species placement is out of dates in places but actively being updated. Please contact the scratchpad editors if you have queries.
If you have arrived here via a search engine - welcome. We would value any thoughts or feedback you might.
