Brachychiton Schott & Endl. has previously been included under Sterculia and its generic status has been uncertain. Characters of the follicles, seed coats and embryo strongly support the retention of Brachychiton as a separate genus. The genus comprises five sections, including one new section, Oxystele Guymer. Characters useful in identification and classification are reassessed and those found to be of most significance are described in detail and illustrated. Chromosome numbers of 2n = 40 for 12 species are recorded for the first time. Keys for the identification of taxa are given. Detailed new descriptions, distribution (including a map based on herbarium specimens), ecology, conservation status and relationship are provided for each taxon, and most taxa are illustrated. Taxa described as new are: B. acuminatus, B. albidus, B. chillagoensis, B. collinus, B. compactus, B. diversifolius subsp. orientalis, B. fitzgeraldianus, B. grandiflorus, B. megaphyllus, B. muellerianus, B. multicaulis, B. obtusilobus, B. populneus subsp. trilobus, B. spectabilis, B. tridentatus and B. xanthophyllus. The following five new combinations are made: B. garrawayae (Bailey) Guymer, B. tuberculatus (W. Fitzg.) Guymer, B. viridiflorus (W. Fitzg.) Guymer, B. viscidulus (W. Fitzg.) Guymer and B. vitifolius (Bailey) Guymer. Naturally occurring hybrids within the genus are frequent between partially sympatric species. Eight hybrids are recorded and described: B. x allochrous, B. x carneus, B. x excellens, B. x hirtellus, B. x incarnatus, B. x roseus, B. x turgidulus and B. x vinicolor.

Taxonomy of some Central, Middle and South West Asian representatives of Lepidium s. l. is revised and updated. Poorly known taxon, L. rubtzovii, is shown to be unrelated to L. coronopifolium s. l., but close to L. lacerum. Three new combinations (L. lacerum subsp. rubtzovii, L. leventii, and L. macrocarpum) are proposed. The names L. deserti, L. persicum subsp. arianum and L. seravschanicum, and Stroganowia kazachstanica are newly recognized as synonyms of L. obtusum, L. ferganense, and L. cardiophyllum, respectively. For L. ferganense and L. macrocarpum, lectotypes are designated. Besides, L. lacerum subsp. rubtzovii is reported for the first time for China (instead of subsp. lacerum), L. leventii for Iran, L. macrocarpum for Tajikistan, and L. obtusum for Afghanistan. In contrast, occurrence of L. lacerum in Uzbekistan and Turkmenistan is considered doubtful.

The following are new combinations: Aleiodes insignis (Brues 1926), Aleiodes lateralis (Cameron 1905), Aleiodes maculicornis (Brues 1926), Aleiodes siccitesta (Morley 1937), Cyclophatnus flavum (Cameron 1910), Rhaconotus striatulus (Cameron 1909), Tolonus cingulatorius (Morley 1912), Zatypota tropica (Morley 1912). Netelia morleyi Townes, Townes & Gupta 1961 is transferred from the subgenus Netelia Gray 1860 to the subgenus Paropheltes Cameron 1907. One new replacement name is proposed: Aleiodes philippinensis nom. nov. for Rhogas lateralis Baker 1917, nec Troporhogas lateralis Cameron 1905. Lectotypes are designated for Antrusa persimilis Nixon 1954, Rhyssalus striatulus Cameron 1909, Troporhogas trimaculata Cameron 1905, Hemiteles cingulatorius Morley 1912, Paniscus ferrugineus Cameron 1889 and for Xanthojoppa inermis Morley 1917. Some previously overlooked type specimens are interpreted and illustrated and some errors in the literature corrected. Hosts are recorded for two genera of Ichneumoninae for the first time: Catadelphops nasutus (Heinrich 1962) was reared from Proserpinus terlooii (Edwards 1875) (Lepidoptera: Sphingidae) in the USA, and Aethianoplis excavata (Roman 1910) was reared from Precis octavia (Cramer 1777) (Lepidoptera: Nymphalidae) in Uganda.

Seven genera new to science, i.e.: Helmutiopsis, Huriopsis, Johnsheardia, Klauskalbia, Kudratovia, Kurokawia and Poeltonia of the Physciaceae are proposed for the ‘Rinodina’ atrocinerea, the ‘Rinodina’ xanthophaea, the ‘Rinodina’ cinnamomea, the ‘Heterodermia’ obscurata, the ‘Rinodina’ straussii, the ‘Anaptychia’ isidiata and the ‘Physconia’ grisea groups consequently that all form strongly supported monophyletic branches in a phylogeny analysis based on a combined matrix of nrITS and mtSSU sequences. Phylogenetic positions of species belonging to the genera Kashiwadia s. l., Leucodermia, Mischoblastia,Oxnerella, Phaeorrhiza s. l., Polyblastidium and Rinodinella s. l. are discussed. Oxnerella afghanica which for the first time recorded as parasitic lichen species from both epiphytic and saxicolous crustose lichens is designated as type species for the genus Oxnerella. Sequences of the recently described Physcia orientostellaris as well as Huriopsis xanthophaea and additional sequences of Kashiwadia aff. orientalis and Mischoblastia aff. oxydata are submitted to the GenBank. The positions of Polyblastidium casaterrinum from Costa Rica, ‘Rinodina’ efflorescens from Białowieża, Poland, and ‘Mischoblastia’ confragosula from Cambodia in the Physciaceae are confirmed in a phylogeny analysis based on the nrITS sequences. The presence of ‘extraneous mycobiont DNA’ in lichen associations is exemplified with earlier incorrect identifications of Heterodermia, Kashiwadia, Kurokawia,Oxnerella and Poeltonia specimens. Fifty-six new combinations are presented: Helmutiopsis alba (for Rinodina alba Metzler ex Arn.), Helmutiopsis aspersa (for Lecanora aspersa Borrer), Helmutiopsis atrocinerea (for Parmelia atrocinerea Fr.), Huriopsis chrysidiata (for Rinodina chrysidiata Sheard), Huriopsis chrysomelaena (for Rinodina chrysomelaena Tuck.), Huriopsis lepida (for Lecanora lepida Nyl.), Huriopsis luteonigra (for Rinodina luteonigra Zahlbr.), Huriopsis plana (for Rinodina plana H.

Morphological, anatomical and chromosome studies of Hyophila crenulata C, Mull. Ex Dus, Thuidium gratum (P. Beauv) Jaeg., Barbula lambarenensis P. Vard.. Stereophyllum nitense Mitt. and Bryum coronatum Schwaegr from Nigeria, were carried out with a view to bridging some knowledge gaps that exist in their characterization and providing insightful information that could be useful in elucidating their taxonomic status. The morphological and anatomical studies revealed several gametophytic and sporophytic attributes which have not been previously reported and which were diagnostic for the moss species studied. The chromosome studies revealed the chromosome numbers to be Hyophila crenulata n = 4; Thuidium gratum n = 12 (10 + 2 m); Barbula lambarenensis n = 3; Stereophyllum nitense n = 9; and Bryum coronatum n = 10. The study concluded that the details of the morphological and anatomical descriptions as well as the chromosome numbers being reported for the first time in this study for the moss species studied could be very useful in their identification and taxonomic delimitation.
