Systematics of Planchonella Pierre: The largest Sapotaceae genus in subfamily Chrysophylloideae

open access: yesTAXON, EarlyView.
Abstract Planchonella is the largest genus in subfamily Chrysophylloideae (Sapotaceae), believed to circumscribe about 110 species, occurring throughout tropical Asia, Australia, and Oceania, as well as the Seychelles and Hawaii. Previous studies have confirmed the monophyly of Planchonella but also identified problems such as species limits of the ...

Taxonomy and dated molecular phylogeny of Allium oreophilum sensu lato (A. subg. Porphyroprason) uncover a surprising number of cryptic taxa

open access: yesTAXON, EarlyView.
Abstract Allium oreophilum, hitherto the representative of the monotypic A. subg. Porphyroprason from the second evolutionary lineage of Allium, is studied in detail. Over about 150 years, A. oreophilum was regarded as a somewhat polymorphous species with two synonyms, all described in the 19th century.

Resolving taxa in a challenging orchid species complex using evidence from phylogenetics, morphometrics and floral scent chemistry

open access: yesTAXON, EarlyView.
Abstract Species can be difficult to circumscribe using morphology alone, and additional data can thus be useful for resolving challenging species complexes. Here we provide a case study of a South African orchid species complex which we resolved by analysing morphology, floral scent chemistry and molecular data.

Phylogenomic evidence reveals non‐monophyly of Paepalanthoideae (Eriocaulaceae) and challenges the broad concept of Paepalanthus

open access: yesTAXON, EarlyView.
Abstract Eriocaulaceae is a pantropical family of approximately 1200 species across 18 genera, with its highest diversity in the Neotropical region. Traditionally, the family has been divided into two subfamilies, Eriocauloideae and Paepalanthoideae, based on floral traits. Here, we use target‐capture sequencing of nuclear markers to test the monophyly
