Oritrophium (Kunth) Cuatrec. is a neotropical genus with a disjunct distribution in the Andes (Bolivia, Colombia, Ecuador, Peru, and Venezuela), the center of Mexico, and the mountains of the Guiana Shield in Venezuela, with a remarkable diversity in Ecuador. We present a taxonomic study for Ecuador that represents the first modern and exhaustive revision of this genus in this country. We recognize eight species and four subespecies. We provide a dichotomous key, descriptions, synonyms, morphological and nomenclatural notes, distribution maps, and photographs of living plants. Three names are lectotypified and two names are neotypified.

A New Species

Microlicia (Melastomataceae) is a Neotropical genus nearly restricted to southeastern Brazil, and the Guiana Shield in Venezuela, with a few species in some places in the Andes of Bolivia and Peru. A new species of Microlicia endemic to the mountains of eastern Andes of Colombia is described and illustrated. Its affinities with other morphologically similar species from Venezuela are also documented. This novelty is the first record of the genus for Colombia and the northern Andes. It is argued that this disjunct distribution of the genus is attributable to the phenomenon of long-distance seed dispersal by wind.

During the taxonomic study of the genus Bothriochloa from India, B. ewartiana was reported for the first time in Asia from India. Earlier, it was known only from Australia, Lesser Sunda Island (Sumbawa, Timor), Philippines (Luzon), and Papua New Guinea (Madang). We have discussed about its amphitropical disjunct distribution over a vast continental gap with respect to some variability reported in the morphological attributes. A hypothesis behind its seclusion from Far East is also discussed. The images of the habitat and habit of B. ewartiana along with its detailed comparison with a close species B. woodrovii are provided. The taxonomic limits of each Indian species of Bothriochloa along with their ranges of morphological variations and distribution have been discussed in a detail. The Indian endemic B. parameswaranii (synonym nova) has been relegated, based on the morphological study, as a new taxonomic synonym of B. insculpta. Moreover, keys to identify closely allied genera and the species of Bothriochloa in India are provided. At the end, identification, taxonomic notes and the range of variations of Dichanthium foulkesii, D. jainii & D. concanense have been discussed in a detail.

First Time

The Praxelinae comprises two genera—Praxelis and Chromolaena—and 19 species in Rio Grande do Sul, the southernmost State of Brazil. This is the first taxonomic treatment of these genera in the state according to their current circumscriptions. Chromolaena squarrosoramosa is formally reported for the first time for the flora of the state. The names C. callilepis and C. paraguariensis are used for the first time to refer to species previously known as Eupatorium polyanthum and E. angusticeps. Eupatorium angusticeps, considered in previous studies endemic to Rio Grande do Sul and probably extinct, is synonymized under C. paraguariensis and has its geographical range extended. Two neglected names, C. elliptica and C. latisquamulosa, are re-established, and C. umbelliformis is synonymized under C. elliptica. Furthermore, C. rhinanthacea is recollected for the first time after 40 years, and C. gentianoides is rediscovered in the state after almost 200 years of the original collection. Identification key and morphological descriptions, as well as distribution maps, field photographs, illustrations and general comments on the biology, ecology and identification of the species are provided.

Three New Species

AbstractThe genus Ericydeus Pascoe (Polydrosinae: Naupactini) distributed throughout the United States of America up to Argentina is revised and a cladistic analysis including 16 species is conducted. Three new species are described: E. bahiensis, E. argentinensis and E. cupreolus. Ericydeus humeralis Hustache is synonymized under E. nigropunctatus (Chevrolat); and E. modestus viridans (Boheman) and E. modestus duodecimpunctatus (Dalla-Torre, Emden & Emden) are elevated to species rank. Other valid species are: E. hancocki (Kirby), E. schoenherri (Perty), E. sedecimpunctatus (Linnaeus), E. yucatanus (Champion), E. roseiventris (Champion), E. quadripunctatus (Champion), E. modestus (Gyllenhal), E. forreri (Champion), E. lautus (LeConte) and E. placidus (Horn). In the cladogram obtained the species from South America gather in a clade (E. argentinensis, E. sedecimpunctatus, E. nigropunctatus, E. schoenherri, E. hancocki, and E. bahiensis) and the species from Central and North America form a separate clade (E. yucatanus, E. roseiventris - E. quadripunctatus, E. cupreolus, E. viridans - E. modestus, E. duodecimpunctatus, E. forreri, E. lautus - E. placidus). The character evolution follows a southern-northern direction. The paper includes a redescription of the genus, redescriptions or descriptions of its 16 species, a dichotomous key, habitus photographs, drawings of diagnostic structures, distribution maps, a cladogram, and a discussion of the phylogeny and distribution of the genus.

This paper presents a taxonomic study of genus Vincetoxicum s.str. from southern Asia. Eleven regional endemic species are recognized on the basis of herbarium studies and fieldwork. Three new species are described: V. lenifoliumsp. nov. (endemic to Pakistan), V. stewartianumsp. nov. (endemic to India), and V. subcanescenssp. nov. (endemic to Pakistan, Kashmir and Tibet). Three species names, V. cabulicum, V. glaucum and V. kenouriense, previously treated as synonyms of V. glaucum, V. canescens and V. hirundinaria, respectively, are resurrected. A neotype is designated for the Afghani endemic V. cabulicum. A lectotype is chosen from the syntypes of V. glaucum. We resolve the long-standing taxonomic problems in three species complexes: V. arnottianum, V. luridum, V. sakesarense, and V. stocksii; V. glaucum, V. canescens and V. cabulicum; and V. hirundinaria and V. kenouriense. Geo-taxonomic distinctions of southern Asian taxa are highlighted by excluding from henceforth the long misrecognized western Eurasian taxa V. canescens and V. hirundinaria. Furthermore, a detailed account of the genus including illustrations of whole plants, leaves and corona, distribution maps, a taxonomic key, morphological descriptions, synonymy, notes, and information on phenology, distribution and habitats is provided. Finally, provisional conservation assessments are provided, which indicate that V. cardiostephanum and V. sakesarense are critically endangered.

Biogeographic Analysis

Using track analysis and cladistic biogeography, we identified areas of endemism of hummingbirds in the Andean and Neotropical regions. Our results point out that the current areas of endemism of hummingbirds occur in the Andes, Guiana Shield, the Lesser Antilles, western Central and North America and the Chiapas Highlands. The cladistic biogeographic analysis suggests a hummingbird distribution shaped mainly by dispersal events.

A New Species

Elaphoglossum Schott ex J. Sm. sect. Polytrichia Christ is characterized by the presence of subulate scales and the absence of hydathodes. We did a molecular phylogenetic analysis using three non-coding plastid markers and found that five species thought to belong to section Elaphoglossum are actually members of section Polytrichia. The five species were previously thought to belong to section Elaphoglossum because they lack the characteristic subulate scales of section Polytrichia. We refer to these species as the Decursivum Group. We assign two other species to this group based on their morphological similarity to the known members of the group. Besides lacking subulate scales on the laminae, the seven species of the Decursivum Group are distinctive by having a submarginal connecting vein, a character otherwise absent in section Polytrichia. The group is entirely Neotropical, occurring at middle elevations and extending from the West Indies and Mexico to Bolivia and southeastern Brazil. For the Decursivum Group, we provide a taxonomic treatment including a key, descriptions, illustrations, distribution maps, discussion, and lists of specimens examined. Lectotypes are designated for Acrostichum miersii Baker and A. papyraceum Fée. A new species from the Andes, E. vascoae F. B. Matos & R. C. Moran, is described and illustrated.

AbstractHypseocharis is a genus endemic to the high Andes and sister to all other Geraniaceae genera. Regarding its basal position in Geraniaceae evolution, its germination ecology can provide important insights into the early evolution of physical dormancy. Imbibition tests performed on seeds of two Hypseocharis populations from Bolivia indicate that their seeds indeed have physical dormancy like all other Geraniaceae. These results indicate that physical dormancy in Geraniaceae evolved during the Eocene before the uplift of the Andes mountains and before the events that led to the cross-Atlantic disjunct distribution of Geraniacae.
