the macro-morphological variation and geographical distribution of six morphologically similar taxa from the Schoeno-plectus corymbosus complex with distinctly muricated nutlets (viz Schoenoplectus confusus subsp. confusus var. confusus and var. rogersii, S. confusus subsp. natalitius, S. muricinux, S. muriculatus and Scirpus corymbosus var. juncif...

... the case of "S. sp. a" from Flora of west tropical africa (Fig. 2) In the Flora of west tropical africa, hooper (1972) distinguished "S[cirpus]. sp. a". Compared with the other west african species it was similar to S. brachyceras hochst. ex a. rich. but it was characterized in having a contracted inflorescence of dark spikelets that was exceeded by the erect stem-like bract and a transversely ridged ...

As part of an ongoing project promoted by the Korea National Arboretum, aimed at tracing the original materials used to describe vascular plant taxa in Korea, we detected problems with the typification of Neoscirpus dioicus Y.N.Lee & Y.C.Oh (2006b: 25) and some nomenclatural issues related to that name.

... A recent study has merged several tropical African Schoenoplectus with transversely rugose nutlets under the name S. muricinux (Verloove et al., 2018). Although the present study positions several of these taxa within the same monophyletic group (e.g., S. confusus, S. muriculatus, S. muricinux) it also places other broadly accepted taxa, like S. decipiens (Browning, 1990;Gordon-Gray, 1995) in the same clade. ...
... Moreover, S. confusus var. rogersii, another taxon in the synonymy of S. muricinux (Verloove et al., 2018), is here shown to be sister to S. brachyceras, a widely accepted taxon (Browning, 1992;Jiménez-Mejías & Cabezas, 2009) also recognized as close to S. muricinux (Verloove et al., 2018), but not placed in its synonymy. Although it is clear that the limits of many of these taxa are not well defined, we re-adopt Browning's (Browning, 1991a) treatment of S. muricinux and its allies until molecular, and additional morphological and micromorphological data can be applied to the problem. ...

Molecular phylogenetic studies based on Sanger sequences have shown that Cyperaceae tribe Fuireneae s.l. is paraphyletic. However, taxonomic sampling in these studies has been poor, topologies have been inconsistent, and support for the backbone of trees has been weak. Moreover, uncertainty still surrounds the morphological limits of Schoenoplectiella, a genus of mainly small, amphicarpic annuals that was recently segregated from Schoenoplectus. Consequently, despite ample evidence from molecular analyses that Fuireneae s.l. might consist of two to four tribal lineages, no taxonomic changes have yet been made. Here, we use the Angiosperms353 enrichment panel for targeted sequencing in order to: (1) clarify the relationships of Fuireneae s.l. with the related tribes Abildgaardieae, Eleocharideae and Cypereae; (2) define the limits of Fuireneae s.s., and (3) test the monophyly of Fuireneae s.l. genera with emphasis on Schoenoplectus and Schoenoplectiella. Using more than a third of Fuireneae s.l. diversity, our phylogenomic analyses strongly support six genera and four major Fuireneae s.l. clades that we recognise as tribes: Bolboschoeneae stat.nov., Fuireneae s.s., Schoenoplecteae, and Pseudoschoeneae tr.nov. These results are consistent with morphological, micromorphological (nutlet epidermal cell shape), and embryo differences detected for each tribe. At the generic level, most sub‐Saharan African perennials currently treated in Schoenoplectus are transferred to Schoenoplectiella. Our targeted sequencing results show that these species are nested in Schoenoplectiella, and their treatment here is consistent with micromorphological and embryo characters shared by all Schoenoplectiella species. Keys to recognised tribes and genera are provided.
