The present paper deals with the taxonomy of Selaginella from Nepal based on the examination of herbarium collections housed in major herbaria of Europe and Asia (with additional collections from virtual herbaria). A total of 25 species are recognised here, while Selaginella trichophylla and S. laxistrobila are two new records for the flora of Nepal, India (Sikkim) and Bhutan; Selaginella monospora var. ciliolata is synonymised to S. trichophylla; detailed descriptions, distribution and ecology and IUCN conservation status assessments (based on literature) are presented. For most of the species, illustrations of the leaves and strobili are provided for identification of the morphologically similar taxa.

Background and aims – The intensive botanical prospections carried out in Gabon since the publication of the national checklist in 2006 have resulted in c. 34 300 new specimens (amounting to 30% of all collections made in the country) and an annual increase of 25 species in average. As a result, 5175 species of vascular plants are now recorded from Gabon, of which 650 are considered endemic. However, most of the recent discoveries have not yet been published. This paper is the first of a series documenting additions to the flora of Gabon, and new records of poorly known species. It concerns specifically new records from the Lower Ogooué Ramsar site, the third largest delta of Africa, and certainly the most intact, which includes 80% of the country’s wetlands and a wide variety of other habitats.Methods – The new records presented here come essentially from fieldwork conducted in Gabon between 2008 and 2016 by the authors and colleagues. Further information comes from the study of herbarium specimens in BR, BRLU, K, LBV, MO, P and WAG. For each species, information on distribution and ecology is given, and the studied Gabonese collections listed. In case of rare or range-restricted species, collections from other countries are also listed, and a distribution map is provided, as well as an evaluation of the conservation status based on the categories and criteria of the IUCN Red List.Key results – We report 18 additions to the flora of Gabon, including four genera new to the country (Capparis, Gisekia, Hoffmanniella and Leptochloa) and the first records of the neotropical Justicia secunda being naturalised in tropical Africa. New distribution records are also provided for 16 rare Gabonese endemics or near-endemics. Some species are also newly reported from Cameroon (Cissus leemansii, Salacia coronata) and Equatorial Guinea (Cissus leemansii, C. louisii, Lychnodiscus grandifolius, Placodiscus resendeanus, Rutidea gabonensis, Uvaria bipindensis). Two species, which were reported in the 2006 checklist based on misidentifications, are excluded from the Gabonese flora.

Abstract. Saensouk P, Saensouk S. 2021. Taxonomic studies and three new records on genus Geostachys (Baker) Ridl. in Thailand. Biodiversitas 22: 3057-3067. A comprehensive taxonomic study and three new records of genus Geostachys (Baker) Ridl. in Thailand have not been reported. This research aimed to study the taxonomical aspect of the genus Geostachys in Thailand based on herbarium collections, fresh materials, and available literatures. Nine species of Geostachys have been recognized with their updated nomenclature in Thailand, namely G. angustifolia K. Larsen, G. chayanii Mayoe, G. decurvata (Baker) Ridl., G. holttumii K. Larsen, G. kerrii K. Larsen, G. penangensis Ridl., G. pierreana Gagnep., G. smitinandii K. Larsen, and. G. tratensis Picheans. & Mayoe. Three species, namely G. decurvata, G. pierreana, and G. penangensis are found to be new records to Thailand. Six species, namely G. angustifolia, G. chayanii, G. holttumii, G. kerrii, G. smitinandii, and G. tratensis were endemic to Thailand. The identification key to species, detailed descriptions, photographs, vernacular name, geographical distribution, ecology, phenology, conservation status, and taxonomic notes have been provided.

A morphological review of the diminutive annual species from the Stylidium despectum R.Br. group (Stylidiaceae) is presented. Twelve species are recognised, of which 10 are endemic in the south-west of Western Australia and two are widespread across southern temperate Australia. Following examination of type material, herbarium collections and field observations, a change of circumscription is presented for S. despectum and S. inundatum R.Br. The former name is applied to a widespread species that occurs in Western Australia, South Australia, Victoria, New South Wales and Tasmania, and is characterised by scattered or rosetted leaves, pink and/or white corolla lobes in a fan-shaped arrangement, and an immobile floral column. S. brachyphyllum Sond. is newly placed into synonymy under S. despectum and a lectotype selected. S. inundatum is redefined as a south-western Australian endemic with scattered leaves, vertically-paired or evenly spreading corolla lobes, and a mobile floral column. A lectotype is designated for S. inundatum, and S. sidjamesii Lowrie & Kenneally is treated as conspecific. S. beaugleholei J.H.Willis is confirmed for Western Australia, South Australia, Victoria and Tasmania. S. asymmetricum Wege, a new and apparently rare species from the Northern Jarrah Forest in south-western Australia, is formally described and revised descriptions are provided for S. longitubum Benth., S. pygmaeum R.Br., S. rhipidium F.L.Erickson & J.H.Willis, S. roseoalatum F.L.Erickson & J.H.Willis, S. roseonanum Carlquist, S. tinkeri Lowrie & Kenneally, S. utricularioides Benth. and S. xanthopis F.L.Erickson & J.H.Willis. A lectotype is designated for S. longitubum Benth. and S. utricularioides var. rosulatum Mildbr. is newly placed into synonymy under S. roseoalatum. A key to species is provided, along with photographs to aid identification. Further field-based studies are required to refine the taxonomy of this group and to better understand the distribution, rarity and conservation status of some of the taxa. In Western Australia, seven species are listed as being of conservation concern, of which S. asymmetricum, S. tinkeri and S. xanthopis require immediate further survey to ascertain whether they should be given Threatened Flora status.

A New Species

On basis of morphological analyses and field investigation, a revision of Bolusiella (Angraecinae; Orchidaceae) was undertaken. We examined 302 specimens from several main herbaria, and for each of the six taxa recognized we provide a morphological description, distribution, habitat, phenology and IUCN conservation status assessment. Distribution maps and an identification key are also provided. Detailed examinations of specimens and comparison with nomenclatural types resulted in one novelty, Bolusiella fractiflexa, which is distributed in lowland and montane forests of Cameroon, Burundi and Rwanda. This species is close to Bolusiella maudiae and B. talbotii in general aspect but differs from them in having only a small or absent spur and a basally fractiflex inflorescence. Some taxonomic changes are made: B. alinae is synonymous with B. talbotii, and B. batesii is lectotypified and considered synonymous with B. zenkeri. Two new records are provided: B. maudiae from Nigeria and B. zenkeri from Liberia.

There are seven endemic species of Boswellia Roxb. ex Colebr. on Socotra Island, Yemen. Boswellia socotrana Balf. f. is a culturally, economically, and ecologically important species on the island. The name Odina aspleniifolia Balf. f. has been considered as a synonym, but there are morphological differences between the two taxa sufficient to justify their distinction at subspecific rank. Therefore, O. aspleniifolia is transferred to Boswellia as B. socotrana subsp. aspleniifolia (Balf. f.) Lvončik. A lectotype is designated for O. aspleniifolia. The distribution and ecology of both subspecies are discussed, as is their conservation status.

A worldwide taxonomic revision of the species belonging to the moss genus Chionoloma Dixon (Pottiaceae) is here presented. Our work is based on the morphological analysis of more than 2600 specimens deposited in different herbaria or collected during field trips. A total of 131 names were found and their nomenclatural types were examined, resulting in the lectotypification of 45 names. It is concluded that Chionoloma is composed of 22 species and one variety, seven of them are here newly combined (C. circinatum (Besch.) M. Alonso, M. J. Cano & J. A. Jiménez; C. cylindrotheca (Mitt.) M. Alonso, M. J. Cano & J. A. Jiménez; C. hyalinoblastum (Broth.) M. Alonso, M. J. Cano & J. A. Jiménez; C. melanostomum (Mitt.) M. Alonso, M. J. Cano & J. A. Jiménez; C. orthodontum (Müll. Hal.) M. Alonso, M. J. Cano & J. A. Jiménez; C. sarawakense (Dixon) M. Alonso, M. J. Cano & J. A. Jiménez; and C. stenocarpum (Thér) M. Alonso, M. J. Cano & J. A. Jiménez). Moreover, 42 names are newly synonymized and a total of 74 new records for various countries are reported. Keys, descriptions, illustrations, photographs, and distribution data of each species are provided.

Abstract The Hkakabo Razi Landscape, in northern Kachin, Myanmar, is one of the largest remaining tracts of intact forest in South-east Asia. In 2016, we undertook a survey in its southern margins to assess bat diversity, distribution and ecology and evaluate the importance of the area for global bat conservation. Two collecting trips had taken place in the area in 1931 and 1933, with four bat species reported. We recorded 35 species, 18 of which are new for Kachin. One species, Murina hkakaboraziensis, was new to science and three, Megaerops niphanae, Phoniscus jagorii, Murina pluvialis, were new records for Myanmar. Our findings indicate high bat diversity in Hkakabo Razi; although it comprises only 1.7% of Myanmar's land area, it is home to 33.6% of its known bat species. This emphasizes Hkakabo Razi's importance for conserving increasingly threatened, forest-interior bats, especially in the families Kerivoulinae and Murininae. There is also a high diversity of other mammals and birds within the Hkakabo Razi Landscape, which supports its nomination as a World Heritage Site.
