Type Studies

Archilejeunea (Spruce 1884: 88) Stephani (1888: 113) is a pantropical genus with about 28 species in two subgenera, subg. Archilejeunea with five species and the remaining ones in subg. Dibrachiella (Spruce 1884: 90) Schiffner (1893: 130) (Gradstein & Buskes 1985). The genus has been well-studied in the Neotropics and Australia (Gradstein & Buskes 1985; Thiers & Gradstein 1989; Gradstein 1994; Gradstein & Schäfer-Verwimp 2012) but the treatments of the African and Asiatic species are incomplete or outdated (e.g., Stephani 1911; Verdoorn 1934; Vanden Berghen 1951; Udar & Awasthi 1981a, 1982; Mizutani 1993; Gradstein et al. 2002). Several species have not been studied since their first publication. Moreover, recent molecular-phylogenetic studies indicate that Archilejeunea is not monophyletic (Wilson et al. 2007). Members of A. subg. Archilejeunea were resolved in a clade with Caudalejeunea (Stephani 1890: 18) Schiffner (1893: 129) and Schiffneriolejeunea Verdoorn (1933: 89), while those of A. subg. Dibrachiella resolved in a distant clade with species of Spruceanthus Verdoorn (1934: 151) and Ptychanthus Nees (1838: 211). As a result, the genus urgently needs revision.

Following recent molecular phylogenetic studies in Old World Gesneriaceae the nomenclatural implications for names in Henckelia are examined. New combinations are made in Codonoboea and Loxocarpus to account for species now excluded from Henckelia. A list is presented in which the current position of all species hitherto assigned to Henckelia is given, including the new combination Henckelia rotundata (Barnett) D.J.Middleton & Mich.Möller. A new combination in Oreocharis is made.

Following recent molecular phylogenetic studies, the genus Sphaeromeria has been synonymized with Artemisia and its taxa are included in Artemisia subg. Tridentatae. The new combination is proposed, Artemisia nuttallii (Torr. & A. Gray) Mosyakin, L.M. Shultz & G.V. Boiko, comb. nov. (= Sphaeromeria argentea Nutt., non A. argentea L’Her.; Tanacetum nuttallii Torr. & A. Gray; Artemisia macarthuri Sòn. Garcia et al., nom. illeg.). Notes on typifications of the names Sphaeromeria argentea and S. capitata Nutt. (now Artemisia capitata (Nutt.) Sòn. Garcia et al.) are provided; both are typified by Nuttall’s specimens from BM. Additional original specimens of these two species recently found in the Turczaninow memorial collection at the National Herbarium of Ukraine (KW) are discussed.

Taxonomic Changes

Molecular phylogenetic studies of complex thalloid liverworts have resolved relationships that require taxonomic and nomenclatural changes. Since Bucegia and Preissia are deeply nested within Marchantia, species formerly placed in these genera are transferred to Marchantia as Marchantia romanica, comb. nov. and Marchantia quadrata, respectively, and placed in the new subgenus, Marchantia subg. Preissia, comb. et stat. nov. The families Exormothecaceae and Corsiniaceae are merged under the earlier name Corsiniaceae. The genus Stephensoniella Kashyap becomes a synonym of Exormotheca and its sole species S. brevipedunculata is transferred to Exormotheca, with the new combination Exormotheca brevipedunculata. In the Cleveaceae, the recent recognition of Clevea as distinct from Athalamia, necessitates the new combination Clevea nana to replace the name Clevea hyalina on the basis of nomenclatural priority.

The Creation

Recent molecular phylogenetic studies (Egan et al., in prep.) have demonstrated widespread polyphyly within the genus Pueraria. A new classification is presented here that delineates monophyletic groups previously considered congeneric with Pueraria. This taxonomic treatment provides several new species combinations and a more natural circumscription of Pueraria by reinstating the genus Neustanthus, transferring one species to Teyleria and establishing two new genera: Haymondia and Toxicopueraria.

Conniella apterygia is redescribed from re-examination of the holotype, two paratypes, and six additional specimens. The genus is closely allied to Cirrhilabrus, sharing similarities in general morphological and meristic details, but is separated from Cirrhilabrus and most other labrid fishes in lacking pelvic fins and a pelvic girdle. Recent molecular phylogenetic studies have provided strong evidence for the deep nesting of Conniella within Cirrhilabrus, contradicting its generic validity and suggesting that the loss of pelvic elements is autapomorphic. Consequently, the species is redescribed and assigned to the genus Cirrhilabrus, as Cirrhilabrus apterygia new combination. The pelvic morphologies of related cirrhilabrin labrids are discussed, and a new synapomorphy is identified for Paracheilinus.

The genus Opuntia is one of the most emblematic of the cactus family (Cactaceae) and a species-rich clade within subfamily Opuntioideae. After molecular phylogenetic studies showed that the traditional broad circumscription of Opuntia could not be retained as the genus was polyphyletic, various segregated genera were recognize based on both morphological data and phylogenetic studies. Here, we reassessed an old and enigmatic taxon, O. schickendantzii, through molecular and morphological investigations. Our results support that O. schickendantzii was best circumscribed within the Salmonopuntia lineage based on molecular and morphological features. As a consequence, a new combination is proposed, and an epitype from the herbarium BAF is designated. An updated description of the taxon with illustrations is also given.

Leaf Size And Shape

The sporophytes of the genus Herbertus are rare or completely absent in some areas. The first discovery of the sporophyte of Herbertus in Europe, on H. sendtneri from a herbarium specimen collected in Austria in 1851, is reported here. We report that finely papillose spores characterize Herbertus species which have originated in the Northern Hemisphere, whereas the spores of the species which have originated in the Southern Hemisphere are tuberculate or shortly spinulose. Based on morphological studies of over 600 herbarium specimens of Herbertus, supported by previously published molecular phylogenetic studies, H. armitanus and H. circinatus are new synonyms of H. sendtneri. It is distinct from other Northern Hemisphere species by its coarsely toothed leaf base, despite large variation in leaf size and shape, and leaf apex cilia. The range of H. sendtneri is now extended to east Africa (Tanzania) and Malesia (Papua New Guinea and the Solomon Islands).

Utricularia is a morphologically and ecologically diverse genus currently comprising more than 230 species divided into three subgenera—Polypompholyx, Utricularia, and Bivalvaria—and 35 sections. The genus is distributed worldwide except on the poles and most oceanic islands. The Neotropics has the highest species diversity, followed by Australia. Compared to its sister genera, Utricularia has undergone greater rates of speciation, which are linked to its extreme morphological flexibility that has resulted in the evolution of habitat-specific forms: terrestrial, rheophytic, aquatic, lithophytic, and epiphytic. Molecular phylogenetic studies have resolved relationships for 44% of the species across 80% of the sections. Scant data are available for phylogeography or population-level processes such as gene flow, hybridization, or pollination. Because nearly 90% of the species are endemics, data are urgently needed to determine how to protect vulnerable species and their habitats.

The genus Hedyotis sensu lato was splitted into several genera on basis of morphological and molecular evidences. Under this generic delimitation, seven new taxonomic treatments, including six new synonyms and one new combination, are proposed for the Flora of China. The name Hedyotis tenelliflora that misapplied to Scleromitrion angustifolium is also corrected with morphological comparison.
