A New Species

The Chimanimani Mountains, located at the Mozambique-Zimbabwe border, are geologically unique in that they consist of quartzites giving rise to peaks and outcrops between zones of schist supporting grasslands. The nutrient-poor quartzitic soils house a high number of endemic plant species. One of these is Sericanthe chimanimaniensis, which is here described as new for science. We give a detailed description and distribution map, illustrations, information on ecology and phenology, and an assessment on the conservation status. An identification key to closely allied species is presented.

Insight Into

Schoenus is a predominately austral genus of sedges in which the Southern African taxa have recently received detailed taxonomic attention, starting with a transfer of 24 species into Schoenus from Tetraria and Epischoenus in 2017. The taxonomy of the Southern African Schoenus species is currently being revised, which has brought insight into the existence of several species new to science. Here, we build on this recent taxonomic work by describing one new species that has been previously overlooked (Schoenus inconspicuus), while including a distribution map, an assessment of conservation status and an updated identification key.

A New Species

SummaryA Gabonese taxon cultivated for decades in the botanic gardens of Europe as Anchomanes nigritianus is shown to be a new species to science, and on current evidence, is best placed as the fourth species of the Gabonese-centred, poorly known genus Pseudohydrosme. Data on the morphological separation between Anchomanes and Pseudohydrosme are reviewed. Although phylogenomic studies may show in future that the two genera need to be merged, for the moment their separation is reinforced on morphological grounds. Anchomanes lacks the spathe tube, ovoid-globose, 2 – 4 locular pistil and thick, lobed stigma on a symmetric, stout style that we show to characterise the redelimited Pseudohydrosme. (Anchomanes has oblong, polygonal, 1-locular pistils, stigmas asymmetric, sessile, thin and disc-like or on asymmetrical conical styles and are pointed or brush-like). In addition, Pseudohydrosme (where known) has stipitate (versus sessile) fruits and on current evidence lacks the lacticifers recorded from Anchomanes. We test the hypothesis that the taxon is a new species to science, naming it as Pseudohydrosme bogneri, and conclude that it is Critically Endangered (Possibly Extinct) using the IUCN 2012 standard. Pseudohydrosme bogneri appears to be the tenth documented probable global extinction of a plant species that has occurred among the narrowly endemic plant species of the Libreville area, Gabon.

A new species of Microlicia is described from the municipality of Morro do Chapéu, Bahia, Brazil. Microlicia morrensis is apparently related to M. petasensis and differs by its leaves that have a denser indumentum of eglandular trichomes, hypanthia densely covered with eglandular trichomes, calyx lobes triangular to widely triangular and lacking a stout eglandular trichome at the apex, petals rounded at the apex, and antepetalous stamens with appendages 4/5 to totally divided into two lobes. Photos of herbarium material and dried floral parts, a distribution map, notes on its conservation status, and an identification key to the species of Microlicieae from Morro do Chapéu are provided.

A New Species

A new species of Calea sect. Calea, endemic to the rocky grasslands of the municipality of Diamantina, Minas Gerais, southeastern Brazil, is described. Calea diamantinensis is morphologically similar to Calea lantanoides which differs by its leaf blade elliptic (vs. ovate to widely ovate), margin entire and straight (vs. crenate and revolute), surface solely glandular-punctuated (vs. villous), receptacle paleae obtrullate (vs. narrowly elliptic), capitulescence composed by 3–4 heads (vs. 6–12 heads), cypselae glandular-punctuated ca. 2.7–3 mm long (vs. non-glandular, ca. 1.8–2.5 mm long) and pappus scales ca. 15–17 (vs. 20–25). Illustration, photos, distribution map, habitat considerations and conservation status are provided, as well as an identification key for Calea species from the municipality of Diamantina, Minas Gerais.

This work presents and describes Hypoxis atlantica, a new species only known from two disjunct coastal areas in eastern Brazil. Despite our best efforts to collect this species in other areas, we had to assess its conservation status as data deficient. We include here a complete description, photographs, a distribution map and an updated identification key to the species of Hypoxis in South America.

Beaucarnea olsonii is described and illustrated from tropical deciduous forests of SW Puebla, Mexico. The new species can be distinguished from other Beaucarnea species by its massively swollen base that abruptly tapers into slender branches, by its conspicuously long stigma, and by its pedicel articulation that occurs at 2/3 of the length of the pedicel below the flower. With this new addition, the total number of endemic species of Beaucarnea for Mexico increases to 10, making this country the greatest center of diversification and endemism for the genus. We also provide a distribution map and a conservation status recommendation for the new species, as well as a key to the Beaucarnea species of southern central Mexico.

In this study, Fritillaria arsusiana (Liliaceae) is described and illustrated as a new species from Hatay province in southern Anatolia, Turkey. It is related to F. amana and F. hermonis by habitus features and broadly campanulate flowers, but differs mainly by its bulb shape and size, smaller leaf and flower features, and flower colour. It has also been morphologically compared with F. wendelboi, F. pinardii, and F. latakiensis. The detailed description, diagnostic characters, original photographs, geographical distribution, habitat and phenology, etymology, conservation status, and identification key of the new and the related species are presented in this study. IUCN conservation status of F. arsusiana is suggested as Critically Endangered (CR).
