Taxonomic notes on Mexican Ruellia (Acanthaceae)

The new nameRuellia comonduensis is provided for the species previously known asR. cordata Brandegee.Ruellia chilpancingana, a new species known only from Guerrero in southwestern Mexico, is described and compared to morphologically similar species. It is unique among Mexican species ofRuellia based on the following combination of characters: caducous bracteoles and secondary bracteoles, multiflowered dichasia from leaf axils, yellowish and cylindric-funnelform corollas, exserted stamens, and few (four or fewer) seeds per capsule. Macromorphological features and pollen ofR. chilpancingana are illustrated.     

Ruellia section Chiropterophila (Acanthaceae): a novelty from Mexico

RAMAMOORTHY, T. P., 1991. Ruellia section Chiropterophila (Acanthaceae): a novelty from Mexico. A brief review of the structure of the genus Ruellia is provided. A new section, ft. section Chiropterophila is described. Ideas regarding evolution in the section are offered. It is suggested that some of the taxa in the section may be neoendemics.     

Ruellia sect.Urceolata (Acanthaceae), a novel species complex from southern Mexico

A new section in MexicanRuellia, R. sect.Urceolata comprising three species (includingR. cedilloi, spec. nova), endemic to Mexico, is described and illustrated. The taxonomic relationship and differentiation of the species are discussed. Evolution in Mexican Ruellas seems to be occurring at the diploid level.     

Aloe nugalensis sp. nov. (Asphodelaceae), a new gypsum endemic from northeastern Somalia

The new species Aloe nugalensis Thulin, a shrubby plant with long, drooping leaves and a drooping, branched inflorescence with long‐pedicellate orange red flowers, is described from a gypsum hill in the Nugaal valley of northeastern Somalia. The only known material is an individual grown in the Botanical Garden of Uppsala University from seeds collected in Nov 1985 that first flowered in Feb 2011.     

Spathacanthus magdalenae sp. nov. (Acanthaceae), a riparian forest species from Veracruz,Mexico

Spathacanthus magdalenae Cast.‐Campos (Acanthaceae) is described and illustrated as a new riparian forest species from central Veracruz and from the eastern slopes of the volcano Cofre de Perote, Mexico. The new species is similar to Spathacanthus parviflorus, but differs in wider leaves and longer corolla tube. A key to all four species of Spathacanthus is provided.     

Eucyclops dumonti sp.nov. from Central Mongolia

Anthropogenic biological introductions have captured the attention of marine scientists and resource managers in recent years. Human-mediated marine bioinvasions are presently acknowledged as often ecologically and financially devastating events. Despite recent increases in scientific interest and financial resources devoted to nonindigenous nuisance species globally, fundamental questions pertaining to taxonomic identity, geographic source, introduction vector and invasive population dynamics frequently remain unanswered. Ecological surveys based on photometric and observational methods are unable to identify cryptogenic taxa, source populations, multiple introductions, or genetic diversity. The twofold goal of this paper is to discuss the application of molecular genetic techniques to fundamental ecological questions pertaining to bioinvasions and to demonstrate the utility of DNA technology in providing data useful in the development of predictive models for marine bioinvasion science.     

Justicia tetrasperma sp. nov.–a linking species between Justicia and Monechma (Acanthaceae)

Justicia tetrasperma , a new species of Justicia sect. Monechma , is described on material from Shaba in Zaire. Its capsules with four smooth and compressed seeds is a character combination in favour of an inclusion of Monechma in Justicia .     

Rhus neoglutinosa sp. nov. (Anacardiaceae) and Teclea borenensis sp. nov. (Rutaceae) from Ethiopia.

Two new species, Rhus neoglutinosa M. Gilbert (Anacardiaceae) and Teclea borenensis M. Gilbert (Rutaceae) are described in preparation for the forthcoming Flora of Ethiopia.     

Zingiberanamalayanum sp. nov. (Zingiberaceae) from India

Zingiber anamalayanum (Zingiberaceae), a new species from the southern western Ghats, India is described and illustrated. A phenetic analyses to assess the similarity indices and the uniqueness of the new species have been performed. A diagnostic key to Zingiber spp. in south India is provided.     

Diospyros korupensis sp. nov. and Diospyros onanae sp. nov. (Ebenaceae) from Cameroon

Diospyros korupensis Gosline is described as a new species endemic to the Korup National Park in Cameroon and neighbouring areas on the slopes of Mt Cameroon. Diospyros onanae Gosline is described as a new species from the South and Southwest Regions of Cameroon allied to the poorly known D. soyauxii Gürke & K. Schum. ex. Gürke.     

Coffeatoshii sp. nov. (Rubiaceae) from Madagascar

A new species of Coffea from southern central Madagascar, C. toshii, is described and illustrated. The new species is similar to C. buxifolia but differs due to its short, broad spreading habit (vs narrow habit), conspicuous domatia (vs inconspicuous), consistently red fruit (vs reddish purple to dull purple or red), longer fruiting pedicel (vs shorter), presence of bracts (vs absence) and occurrence at lower elevations (vs high elevation).     

Xiphion heracleanum sp. nov. (Iridaceae) from Morocco

As a part of the revision of Xiphion (Iris subg. Xiphion) for the ‘Flora Iberica’ project, some material collected in the 19th and 20th centuries in the Tangiers area (northern Morocco) was found impossible to assign to any of the known taxa in the genus. In part, they resembled X. junceum and X. rutherfordii, but showed a peculiar combination of vegetative and floral characters which to date is exclusive. Accordingly, the new species X. heracleanum Mart. Rodr. & M. B. Crespo is described for these plants, and evidence is reported to justify the adopted treatment. Relationships to other taxa in the genus are also discussed, and the new combination X. rutherfordii (Mart. Rodr., P. Vargas, M. Carine & Jury) Mart. Rodr. & M. B. Crespo comb. nov. is provided.     

Burmannia bengkuluensis sp. nov. (Burmanniaceae) from Sumatra

A new species of Burmannia (Burmanniaceae), Burmannia bengkuluensis Tsukaya et Daernadi, discovered in a swamp adjacent to Bengkulu Airport, Sumatra, Indonesia, is described. It has poorly developed photosynthetic leaves and resembles B. ledermannii Jonker, described from a specimen collected in Palau, in having poorly developed leaves, narrowly 3‐winged erect flowers, and in particular, funnel‐shaped anthers, but differs in having dark purple flowers, longer outer perianth lobes, well‐developed, fan‐shaped inner perianth lobes, and a thick and short style. Sequence data on genomic DNA regions covering ITS1 and ITS2 are also provided.     

Cheirostylis seidenfadeniana sp. nov. (Orchidaceae) from India
