Abstract Three species belong to the genus Convolvulus L. from the Convolvulaceae family, new to Flora of Western Desert District were recorded. These species were Convolvulus cantabrica L., Convolvulus reticulatus Choisy and Convolvulus stachydifolius Choisy. Species were photographed, their taxonomical and ecological characters, as well as their geographical distribution in the Western Desert were demonstrated. Plant samples were collected, precisely identified, dried and herbarium specimens were prepared and deposited at Anbar University Herbarium (AUH). Some notes on habitat, flowering and fruiting periods were provided. The means and reasons that helped these species to be distributed in new places within the Western Desert District of Iraq were realistically discussed, it was found that there was no sample of the three mentioned species that were collected from the Western Desert District at all.

Some species of the subgenus Tachycines (Gymnaeta) are cavernicolous. In this paper, three new species of this subgenus, namely Tachycines (Gymnaeta) zaoshu sp. nov., Tachycines (Gymnaeta) shuangcha sp. nov., and Tachycines (Gymnaeta) tongrenus sp. nov., from karst caves in Guizhou Province, China are described. The results of this study expand our knowledge of the geographical distribution of the cave species of the subgenus Tachycines (Gymnaeta) in China. The morphological photographs of the three new cave species are provided.

Three new species in the diatom genus Eunotia were found in the freshwater ponds and streams of Acadia National Park, Maine, USA. Eunotia novaeangliae sp. nov. belongs to the E. incisa group, species with nose-like apices and terminal raphe fissures distant from the ends. It is most similar to E. tenelloides in that species cluster, although differs in the valve shape, geographical distribution, several ultrastructural details and slight but consistent differences in valve dimensions and striae density. Eunotia panda sp. nov. is in the E. bilunaris group, species with slight even curvature and smooth margins of the valves. However, E. panda can be distinguished from E. bilunaris by dorsally slightly recurved apices with rounded ends, ultrastructural details and noticeably constant valve width. Eunotia spatulata sp. nov. is most similar to E. eurycephala, but differs from that taxon by having straighter and significantly larger valves with more swollen apices. All three taxa were sufficiently abundant in the samples collected from the park that they could be found in both SEM and LM microscopes. Eunotia novaeangliae and E. panda have both been illustrated in other publications before but not named. All three species occurred in waters of low conductivity and pH, typical for the genus. Acadia National Park appears to be a hotspot for Eunotia species diversity, and further study of the oligotrophic waters of this site is certainly warranted.

Three new species of Rubiaceae from Central Africa are described and illustrated. Chassalia lutescens O.Lachenaud & D.J.Harris (widespread from Cameroon to Democratic Republic of Congo) is recognised inter alia by the T-shaped ventral furrow of the seeds and the orange-yellow discoloration of inflorescences in herbarium specimens. Psychotria nodiflora O.Lachenaud & D.J.Harris (Central African Republic, Congo-Brazzaville and Democratic Republic of Congo), belonging to Psychotria subgen. Psychotria sect. Involucratae, is unique among African species of the genus in having paired axillary inflorescences. Psychotria pteropus O.Lachenaud & D.J.Harris (Central African Republic and Democratic Republic of Congo) belongs to Psychotria subgen. Tetramerae; it is closely related to P. leptophylla Hiern but differs in its narrow corolla tube and globose to ellipsoid fruits.

Although Africa and Indonesia have not been particularly well surveyed for Mycosphaerella leaf spot fungi, several species are known to occur on Eucalyptus leaves in these areas. Three new species of Mycosphaerella with anamorph states are described from herbarium specimens and cultures in the present study. Mycosphaerella suttoniae and Mycosphaerella heimioides are described from Eucalyptus leaves from Indonesia. The former species is of particular interest, because its anamorph Phaeophleospora epicoccoides is the first species of Phaeophleospora linked to Mycosphaerella. Mycosphaerella irregulariramosa is described from Eucalyptus saligna growing in the Northern Province of South Africa. Both M. irregulariramosa and M. heimioides have Pseudocercospora anamorphs, and these are described as Pseudocercospora irregulariramosa and Pseudocercospora heimioides. Notes are also provided on the host range and geographic distribution of previously described species of Mycosphaerella on Eucalyptus leaves in other parts of Africa and in Indonesia. Key words: Eucalyptus, Kirramyces, Mycosphaerella, Phaeophleospora, Pseudocercospora, systematics.

Taxonomic notes are provided in some Acanthoderini genera. Three new species are described: Scythropopsis intricata Santos-Silva, Botero and Wappes from Mexico, Aegomorphus robustus Santos-Silva, Botero and Wappes and Eupromerella boliviana Santos-Silva, Botero and Wappes from Bolivia. The following synonymies are proposed: Psapharochrus Thomson, 1864 as synonym of Aegomorphus Haldeman, 1847; Acanthoderes (Psapharochrus) albomaculatus Fuchs, 1963 and Acanthoderes griseomaculata Zajciw, 1971 as synonyms of Symperasmus alboniger (Bates, 1861); Pteridotelus contaminatus Thomson, 1865 as synonym of Scythropopsis melanostictica (White, 1855); Psapharochrus jameswappesi Tavakilian, 2018 as synonym of Aegomorphus wappesi (Galileo, Martins & Santos-Silva, 2015); and Psapharochrus histrio Casey, 1913 and Psapharochrus guatemalensis Casey, 1913 as synonyms of Aegomorphus circumflexus (Jacquelin du Val, 1857). Acanthoderus circumflexus Jacquelin DuVal, 1857 is proposed as nomen protectum and Acanthocinus rusticus Klug, 1829 as nomen oblitum. Aegomorphus contaminatus (Thomson, 1965) is revalidated. Scythropopsis Thomson, 1864 and Symperasmus Thomson, 1864 are herein elevated to genus rank. The geographical distribution of ten species is expanded and a key to differentiate Acanthoderes, Aegomorphus, Scythropopsis, and Symperasmus is provided.

Three new species of the genus Craspedomerus from China are described and illustrated: C. giganteus Li & Zhou sp. n. from Sichuan, C. gongshanus Li & Zhou sp. n. from Yunnan and C. zhangi Li & Zhou sp. n. from Tibet. Four species are reported for the first time from China: C. sinetuber (Coiffait, 1977a) from Tibet, C. cyanipennis Scheerpeltz, 1976b, C. ganeshensis Coiffait, 1983 and C. glenoides (Schubert, 1908) from Yunnan. These four and two additional species previously recorded from China (C. beckeri Bernhauer, 1934 and C. violaceipennis Cameron, 1928 are redescribed and illustrated. Sensory peg setae located on the underside of the paramere of the aedeagus of all nine Chinese species are compared using scanning electron microscopy (SEM) and the result shows that this character is useful for species identification. A key to the Chinese species of Craspedomerus is presented and geographical distribution of all sixteen species of Craspedomerus is mapped.

The paper contains results of fi eld observations of plants and cameral research of herbarium specimens kept in the Herbarium of Komarov Botanical Institute (LE), included in the aggregate Draba cinerea Adams s. l. (D. cinerea, D. arctica J. Vahl, D. arctogena (E. Ekman) E. Ekman, D. oblongata R. Br. ex DC., D. parvisiliquosa Tolm., D. taimyrensis Tolm.). The problem of differentiation and identification of the taxa comprising the aggregate is discussed. The distribution of several species is clarified. Three new species are described from the Northern Russia: D. metaarctica Petrovsky, D. tolmatchevii Petrovsky and D. tundrostepposa Petrovsky. A key for determination of the species of the aggregate is given.

The geographic location, climatic, and soil conditions of Samar Island render a mosaic of varied habitats which harbor numerous endemic, rare, and endangered species of plants. The island province is one of the centers of plant endemism in the Philippines. Included in this rich biodiversity of flora are members of genus Begonia of the family Begoniaceae. In 2018, researchers of the University of the Philippines found in the island three unknown Begonia species. With rhizomatous habits, persistent stipules, protandrous inflorescences, four-tepaled flowers, three winged capsules and bifid placenta, the three species are clearly members of Begonia section Baryandra. Studies of literature, herbarium specimens, and living plants support the recognition of the three new species: Begonia sohoton, Begonia tarangban and Begonia burabod.
