Separate Genus

Following recent studies showing that Asian Schefflera should be treated under the separate genus Heptapleurum, the names for the Thai species belonging to this genus are listed. Two new combinations are proposed for S. bengalensis and S. poomae. For two species of Schefflera recognized, S. pueckleri and S. simulans, different epithets must be used under Heptapleurum, namely H. calyptratum and H. affine.

Species Groups

ClubionaLatreille, 1804, with more than 500 named species, is one of the largest genera of Araneae. The genus has 15 synonyms, most of which are not listed in the World Spider Catalog (2018) and unknown to many arachnologists. The most comprehensive survey ofClubionasensu lato by Wunderlich (2011) also lacked a few synonyms. In this paper all genus group names described inClubionaare listed with their type species. Most of these names correspond to the species groups recognised inClubionasensu lato. We agree thatPorrhoclubionaLohmander, 1944 (=Clubionagenevensis-group) deserves a status of a separate genus and provide the diagnosis of this taxon. Three species ofPorrhoclubionathat occur in Central Asia are surveyed, and two of them are described as new to science:P.laudata(O. Pickard-Cambridge, 1885),comb. n. (♂♀, Xinjiang, Tibet, China),P.bosmansisp. n.(♂♀, Tajikistan), andP.moradmandisp. n.(♂♀, Fars, Iran). It seems that all records ofP.genevensisL. Koch, 1866 from China refer toP.laudata. The records ofClubionavegetaSimon, 1918 from Tajikistan and Iran refer toP.bosmansisp. n. andP.moradmandisp. n., respectively. The following new combinations have been established:Porrhoclubionadecora(Blackwall, 1859),comb. n.,P.diniensis(Simon, 1878),comb. n.,P.leucaspis(Simon, 1932),comb. n.,P.minor(Wunderlich, 1987),comb. n.,P.pseudominor(Wunderlich, 1987),comb. n.,P.pteronetoides(Deeleman-Reinhold, 2001),comb. n.,P.vegeta(Simon, 1918),comb. n.,P.viridula(Ono, 1989),comb. n., andP.wunderlichi(Mikhailov 1992),comb. n.(all ex.Clubiona). SEM study of the structure considered earlier as scopula inClubionaandPorrhoclubionareveals that it is represented by several lateral rows of movable macrosetae (spines) with a locking mechanism.

New names are proposed for the fossil European Tertiary species of Ilex (The Palaeoflora Europaea Project): Ilex angustifolioides nom. nov., Ilex boulayi nom. nov., Ilex friedrichii nom. nov., Ilex latifolioides nom. nov., and Ilex opacina nom. nov. Ilex integrifolia Baikovskaja from Central Asia is renamed Ilex aschutassica nom. nov. (non extant Ilex integrifolia Hort. ex Vilmorin and Ilex integrifolia Chapman ex Knowlton). Ilex mormonica nom. nov. of North America is proposed in place of Ilex acuminata Becker (fossil) non Ilex acuminata Willdenow (extant). Ilex polarica nom. nov. from Greenland is validated in place of Ilex macrophylla Heer (fossil) non Ilex macrophylla Blume (extant). Ilex fortunensis Hahn (extant) is renamed Ilex hahnii nom. nov. (not fossil Ilex fortunensis van der Burgh). Ilex subrotunda sp. nov. is validated instead of the previously invalidly published I. ohashii, lacking holotype designation when published. Fossil-species of Ilex, based on the dispersed pollen, Ilex major, I. colchiciformis, I. hyrcaniformis, I. macroclavata, I. tener, are transferred to the pollen fossil-genus Ilexpollenites. Fossil-species based on leaves, Ilex artocarpidioides and Ilex ovata are segregated into a separate genus Celastrilex gen. nov. Fossil-species Ilex pseudostenophylla, based on leaf remains, is excluded from Ilex and placed into a new fossil-genus Frangulops gen. nov. The following new combinations are proposed: Ilex ulmacea comb. nov., Ilexpollenites: Ilexpollenites major comb. nov., I. colchiciformis comb. nov., I. hyrcaniformis comb. nov., I. macroclavata comb. nov., I. tener comb. nov.; Celastrilex artocarpidioides, C. populifolia; Frangulops pseudostenophylla. Furthermore, Celastrus ulmaceus is neotypified; Ilex acuminata Saporta, I. berberidifolia, I. mougeotii and I. rueminiana are lectotypified.

Seed Coats

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.

Infraspecific Taxa

The pantropical genus Schefflera J. R. Forst. & G. Forst. (Araliaceae) was recently found to be polyphyletic, making it necessary to restrict the generic name to a small clade in the southwest Pacific and to transfer the members of the four remaining clades to other genera. Recent studies of the Neotropical clade have shown that it comprises five morphologically and geographically coherent subclades, each of which is being recognized as a separate genus. In the present synopsis, Crepinella Marchal is resurrected to include the 33 currently recognized species and four infraspecific taxa belonging to one of these subclades, necessitating 36 new combinations (32 species, two subspecies, and two varieties); two names are also lectotypified. Members of Crepinella can be recognized by their leaves with coriaceous leaflets and small stipular ligules, compoundumbellate inflorescences, and 2- to 5-carpellate ovaries, coupled with a distribution that is largely restricted to montane vegetation on the sandstone tepuis of the Guiana Shield, with just three species occurring on sandstone substrates elsewhere in Brazil, Colombia, Ecuador, and Peru.

The taxonomic status of the genus Pernettya Gaud. (Ericaceae) has been assessed by comparing morphological, anatomical, chemical and cytological characters between Pernettya, Gaultheria L. and a number of other genera in the Gaultheria group of the tribe Andromedeae. It has been concluded that Pernettya is not sufficiently distinct from Gaultheria to be maintained as a separate genus. Two new names and fifteen new combinations within Gaultheria are here proposed.

Dissochaeta is a plant genus of woody climbers, classified in the tribe Dissochaeteae (Melastomataceae). The taxonomic history of the genus is complicated and includes some allied genera like Dalenia, Diplectria, Macrolenes and Omphalopus. Most of them are already regarded as synonyms of Dissochaeta except for Macrolenes which is considered a separate genus here as well. Dissochaeta is characterised by its scrambling habit, interpetiolar outgrowths, 4-merous flowers, dimorphic stamens and berry-like fruits. A taxonomic revision of Dissochaeta is presented, which includes references, a complete list of synonyms, detailed morphological descriptions of the species and an identification key, as well as information on the distribution, habitat and ecology, vernacular names, notes and lists of examined specimens. Fifty four species and two varieties of Dissochaeta are recognised. We designate several lectotypes, propose eleven new combinations and we describe one new species and one new variety.

Abstract—Doellingeria and Eucephalus form the earliest-diverging clade of the North American Astereae lineage. Phylogenetic analyses of both nuclear and plastid sequence data show that the Doellingeria-Eucephalus clade consists of two main subclades that differ from current circumscriptions of the two genera. Doellingeria is the sister group to E. elegans, and the Doellingeria + E. elegans subclade in turn is sister to the subclade containing all remaining species of Eucephalus. In the plastid phylogeny, the two subclades are deeply divergent, a pattern that is consistent with an ancient hybridization event involving ancestral species of the Doellingeria-Eucephalus clade and an ancestral taxon of a related North American or South American group. Divergence of the two Doellingeria-Eucephalus subclades may have occurred in association with northward migration from South American ancestors. We combine these two genera under the older of the two names, Doellingeria, and propose 12 new combinations (10 species and two varieties) for all species of Eucephalus.
