A New Species

Cyanea heluensis H. Oppenheimer, sp. nov., a new, narrowly distributed endemic species, is herein described and illustrated with line drawings and digital field photos. It is currently known from a single mature plant and is restricted to the upper Helu planeze on leeward Mauna Kahalawai, West Maui, Hawaiian Islands. It differs from all other species of Cyanea Gaudich. with its narrow, shallowly lobed leaves, gently curved muricate corollas, and undulate sepals caducous in fruit. A key to the new species and its congeners on Mauna Kahalawai is provided. Its conservation status and efforts to propagate the species are discussed.

A New Species

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.

We describe here Begonia medeiroii, a narrow endemic species from the Atlantic Rainforest. The conservation status of this species was assessed as critically endangered according to IUCN criteria. This species resembles to B. catharinensis and B. hirtella in some characteristics, differing among other features due the presence of adventitious vegetative buds on the adaxial surface of the leaves.

A New Species

A new species of Senecio section Adamantina is here described as Senecio hortensiae (Senecioneae, Asteraceae), an endemic species from Parque Nacional dos Pontões Capixabas, Espírito Santo state, Brazil. This new species is recognised by the sessile leaves densely clustered at the median part of the stem and by the radiate capitula in a terminal lax panicle. It is closely related to Senecio graciellae but differs basically by the size and margins of the leaves, capitulescence and number of ray florets. Illustrations, comments, distribution map, and conservation status are provided for the new species. Additionally, a diagnostic key to the species of Senecio section Adamantina is provided.

Onosma ghahremanii (Boraginaceae) is described and illustrated as a new endemic species from the Alborz Mts., N Iran. The new species is related to O. gaubae, O. borragoidinum and O. microcarpum, but differs from them in indumentum type, corolla color and stamen characteristics. Some notes are also presented on the ecology, distribution, and conservation status of the new species and a distribution map is provided.

A new species of Trigonachras from Borneo is described and illustrated. Trigonachras postardanjeisin is endemic to the ultramafic soils of the Tawai Forest Reserve in Sabah, Malaysia (Borneo). It is morphologically close to the widespread Trigonachras acuta but differs by its glabrous inflorescence and infrutescence axes and fruits. The two species also differ by their ecology and distribution. Line drawings are provided for the new taxa, along with discussions of its morphological affinities and preliminary risk of extinction assessment.

A New Species

A new species of gecko of the genus Hemidactylus (Squamata: Gekkonidae) is described from São Nicolau Island, Cabo Verde Archipelago, and the Sal and Boavista island populations of Hemidactylus boavistensis (i.e., Hemidactylus boavistensis boavistensis comb. nov. and Hemidactylus boavistensis chevalieri comb. nov.) are recognized as subspecies. Hemidactylus nicolauensis sp. nov. is genetically distinct from H. bouvieri, to which it has previously been referred, and from all other closely related endemic Hemidactylus from Cabo Verde Islands in mitochondrial (12S & cyt b) and nuclear (RAG2, MC1R) markers. It is characterized morphologically by its distinct colouration and a diagnostically different arrangement of digital lamellae. With the description of this new species, São Nicolau is now known to harbour three single-island endemic gecko species, and the documented reptile diversity in Cabo Verde is raised to 23 endemic species. As a result of our taxonomic changes, existing conservation regulations should be updated and the conservation status of these taxa should be re-evaluated.

A New Species

Microlicia woodii is described as a new species from the Meseta de Motacú, Santiago de Chiquitos, eastern Bolivia, a region rich in endemic plants. The new species seems to be closely related to Microlicia sphagnicola, and can be recognized by a combination of elliptic leaf blades 8–10 × 3.2–5 mm, glandular-punctate on both surfaces, petioles 0.2–0.4 mm long, rectangular and dorso-ventrally flattened, solitary 5–6-merous flowers, external and internal intercalycine eglandular trichomes ca. 1–2 mm long, pink petals, and dimorphic, bicolored and polysporangiate anthers. Line drawings, photographs, a distribution map, and notes on its conservation status are provided. Additionally, we designate a lectotype for Microlicia insignis and document the first records for this species in Bolivia, at Parque Nacional Noel Kempff Mercado.
