Parahyparrhenia bellariensis, an extremely rare and highly narrow endemic grass, has been rediscovered after almost 184 years from Cuddapah [Kadapa] district, Andhra Pradesh. The first description of its complete habit, basal portion and other features of the spikelets are provided along with new locality of its occurrence. In addition, photographs of the habitats, live plants, and a key to distinguish two Indian endemic species, distribution map and illustration are provided. As per the IUCN Red List Criteria this species is assessed here as Critically Endangered (CR). In order to facilitate the prospective conservation of this grass, we have discussed about the peculiarity of its habitat.

Two new micro-endemic species of Eriocaulaceae are described from the Campos Rupestres of Serra Nova State Park, a conservation unit located in the Espinhaço Range in northern Minas Gerais state, Brazil. Herein we provide descriptions, illustrations, photographs and maps, together with notes on morphology, distribution, phenology, taxonomy, and conservation. Paepalanthus ferrugineus is distinguished mainly by the reddish-brown involucral bracts, surpassing the floral disc, with the apex attenuate and tufted adaxially, tufted sepals and hairy petals. Syngonanthus polyaxis is easily differentiated by the inflorescence architecture with three morphologically distinct axial parts. Both species are considered Critically Endangered according to the IUCN Red List criteria.

A New Species

The new species Chiococcagrandiflora Lorence & T.Van Devender from Sinaloa and Sonora, Mexico differs from its congeners by its larger, showy white flowers in compact cymes of 3–9, and infundibuliform corollas 16–20 mm long with tubes 13–17 mm long and lobes 3–3.5 mm long. Its distribution, habitat, and relationships are outlined. The conservation status for this species is estimated to be Endangered (EN) based on IUCN Red List Criteria.

A New Species

A new species of indotyphlid caecilian amphibian, Hypogeophis montanus sp. nov., is described based on a series of specimens from the Seychelles island of Mahé, collected from two localities in 2013 and 2015. The new species most closely resembles the Seychelles (Mahé) endemic H. brevis in being short (maximum known total length in life ca. 110 mm) and long snouted, but differs by having more vertebrae, a relatively smaller head, and substantially distinct mitochondrial and nuclear gene sequences. Hypogeophis montanus sp. nov. is known from higher elevations (718–731 m) than H. brevis (ca. 350–650 m), and its elevationally restricted distribution on a single small island likely renders it threatened under IUCN Red List criteria. Hypogeophis montanus sp. nov. is the third species of small and long-snouted caecilian reported from the Seychelles. Along with H. brevis and H. pti, H. montanus sp. nov. is among the smallest known species of caecilian and possibly has the smallest global distribution.

A New Species

Begonia tinuyopensis is described and illustrated as a new species from Zamboanga del Norte, Philippines. This new species resembles B. mearnsii by having a decumbent stem, scattered hairs over the entire plant, terminal inflorescence bearing 2 staminate tepals and 5 pistillate tepals. However, Begonia tinuyopensis is distinct by having sparse pilose (vs. matted with long brown hairs) stems, ovate (vs. suborbicular to subreniform) leaves and glabrous (vs. densely pubescent) ovary. We assign B. tinuyopensis as Endangered (EN) following IUCN Red List Criteria.
