A taxonomic revision of the 17 Caribbean-endemic species of Wittmackia (Bromeliaceae) is presented. This group is a monophyletic lineage previously circumscribed as Hohenbergia subg. Wittmackiopsis but later transferred to Wittmackia based on phylogenetic and morphological evidence. This taxonomic treatment includes a complete overview of the morphological variation of the species, their geographical distribution and habitat, and notes on their ecology and conservation. A taxonomic key for the identification of the species is provided. Finally, complete descriptions with comments on the taxonomy, geographic distribution and habitat are presented.

As Species

Within Astraea Klotzsch (1841: 194), Astraea lobata (Linnaeus 1753: 1005) Klotzsch (1841: 194) may be considered the most taxonomically complex species due to its wide geographical distribution and the several varieties that have been proposed for this species by Müller Argoviensis (1866, 1874). In his concept, Müller Argoviensis (1866) united under Croton lobatus Linnaeus (1753: 1005) plants with 3–5-partite leaves almost as long as the petioles, subulate stipules, the bracts not well developed and ovaries with varied indumentum. In De Candolles’s Prodromus, Müller Argoviensis (1866) recognized eight varieties, maintaining this concept in the Flora Brasiliensis (Müller Argoviensis 1874) with few modifications. Morphological characters and geographical distribution support the recognition of some of these varieties as species distinct from A. lobata. As part of an undergoing taxonomic revision of Astraea, these distinct taxa must be validly published for further studies on this genus. Therefore, in this note we propose these novelties with commentaries about morphology and geographic distribution, along with photos to illustrate them and lectotypifications when necessary.

Morphological Differences

A recent study of European annual taxa of Alyssum has revealed that A. simplex includes two cytotypes (diploid and tetraploid) which differ in genetic markers, evolutionary history, and monoploid relative genome size. In this paper we present a new taxonomic treatment of A. simplex in which we treat the two cytotypes as two separate species. We select and discuss suitable names for both taxa (diploid A. simplex and tetraploid A. collinum), examine their morphological differences and survey their geographic distribution. In addition, we compare both cytotypes with the morphologically similar and genetically related species A. strigosum and designate lectotypes and a neotype of several relevant names.

A New Species

A taxonomic revision of Flemingia subg. Rhynchosioides based on morphology and molecular information (matK and ITS) is presented. The subgenus comprises six herbaceous taxa (F. gracilis, F. mukerjeeana, F. nilgheriensis, F. rollae, F. tuberosa and F. vestita). All species except F. vestita are endemic to India. Morphological evidence and molecular phylogeny revealed that the subgenus is monophyletic. Nevertheless, the systematic position of F. tuberosa remains unclear on account of its unique ecology and inflorescence. A new species, F. mukerjeeana, is described and four binomials, namely F. gracilis, F. nilgheriensis, F. tuberosa and F. vestita have been lectotypified. Furthermore, all species have been described, illustrated and their ecology discussed. A taxonomic key including the recently described species from Thailand, F. sirindhorniae, is also provided for easy identification.

Othonna L. (Asteraceae: Senecioneae: Othonninae) is a genus of some 120 species concentrated in the Greater Cape Floristic Region (GCFR) of South Africa, with a few species extending into southern Namibia, Angola, and Zimbabwe. The South African species of Othonna were last revised more than a century ago, and many species, particularly from the southern African winter rainfall region, remain poorly understood. This study focused on the geophytic species comprising the O. bulbosa group, distinguished by their tuberous rootstock and annual, leafy, aerial stems. A comprehensive taxonomic treatment is presented, including descriptions, complete nomenclature and typification, illustrations, and geographical distribution. Twenty-five species are recognized, of which four are newly described (O. lilacina Magoswana & J. C. Manning, O. nigromontana Magoswana & J. C. Manning, O. revoluta Magoswana & J. C. Manning, and O. sinuata Magoswana & J. C. Manning), and 18 names are reduced to synonymy. The species differ in habit, shape and incision of foliage, capitulum type (radiate vs. disciform), number of involucral bracts, pappus length, and cypselae (myxogenic vs. nonmyxogenic). We place the species into four morphologically diagnosable series (series Heterophyllae Magoswana & J. C. Manning, series Disciformes Magoswana & J. C. Manning, series Perfoliatae Magoswana & J. C. Manning, and series Undulosae Magoswana & J. C. Manning) based on habit and capitulum type.

This study presents a taxonomic revision of the Pteronia adenocarpa group. Six species are recognised within this group, namely P. adenocarpa, P. armatifolia, P. elongata, P. hutchinsoniana, P. stoehelinoides and P. viscosa. The group is distinct in its characteristic basally hairy cypselae, as opposed to the glabrous-glossy, glandular and/or variously hairy cypselae with the hairs evenly distributed throughout the surface found in the remaining species of the genus. We here present a detailed taxonomic treatment with descriptions, nomenclature, diagnostic characters, geographical distribution and maps, ecological information as well as the key to the species.

Abstract—Rogiera (Guettardeae, Rubiaceae) is a Neotropical genus distributed from Mexico to northern South America that includes shrubs, treelets, or trees, which were previously treated in the taxonomically controversial and confused Rondeletia complex. Rogiera can be recognized among other Rubiaceae by the combination of multiflowered inflorescences, heterostylous flowers, quincuncial corolla aestivation, a hairy ring at the corolla mouth, and capsular fruits with loculicidal dehiscence. Despite the recent taxonomic circumscription of Rogiera there is not a comprehensive taxonomic treatment to it. Moreover, regional floristic treatments disagree on the species circumscriptions, with discrepancies in the number of species of Rogiera from 11 to 20. Based on molecular and morphological evidence studied on field and herbarium specimens, we present a taxonomic revision of Rogiera. We recognize ten species; Mexico is the center of diversity with nine species, four of them endemic. An identification key, descriptions, distribution maps, nomenclatural history, phenological data, and illustrations of all the species in the genus are provided for the first time. Several names required lecto- or epitypifications designated here.

First Time

A comprehensive taxonomic treatment for the New World genus Duranta L. (Duranteae, Verbenaceae) is presented for the first time. The genus consists of shrubs or small trees that are largely distributed in the Neotropics. The analyses of the morphological features support the recognition of 31 Duranta species. Duranta repens L. var. canescens Moldenke and D. mutisii L. f. serrulata Moldenke are elevated to the species rank. The previously misunderstood identity of D. obtusifolia Kunth is here untangled and properly discussed, while D. buxifolia Poir., endemic to the Caribbean, and D. xalapensis Kunth, endemic to Mexico, are resurrected from the synonymy of D. triacantha Juss. and D. erecta L., respectively. Eight taxa are here synonymized: D. brachypoda Tod. (= D. erecta), D. repens var. lopez-palacii Moldenke (= D. canescens P. Moroni), D. repens var. serrata Moldenke (= D. stenostachya Tod.), D. sprucei Briq. var. breviracemosa Moldenke (= D. mutisii), D. arida subsp. serpentina R. W. Sanders & Judd (= D. arida Britton & P. Wilson), D. peruviana var. longipedicellata Moldenke (= D. peruviana Moldenke), D. parvifolia Moldenke (= D. vestita), and D. vestita var. glabrescens Moldenke (= D. vestita Cham.). Duranta cajamarcensis Moldenke and D. parviflora Turcz. are reclassified as belonging to genera Citharexylum L. and Priva Adans., respectively. Lectotypes are designated for the names D. recurvistachys Rusby (second-step), D. rostrata Pasq., and D. xalapensis Kunth. Furthermore, D. penlandii Moldenke is reported for the first time in Colombia.
