Revision of the genus joosia (rubiaceae)

Brittonia - Seven species ofJoosia are recognized, four of which are new:J. ulei,J. aequatoria,J. standleyana, andJ. macrocalyx. All of the species are confined to western South America from...     

Revision of the genus Haniffia (Zingiberaceae)

The genus Haniffia is revised, in comprises two species of which one is described as new: H. albiflora from Thailand. Both species are illustrated.     

Revision of the genus Froesia (Quiinaceae)

Froesia venezuelensis, a new species from Venezuela, is described, and the two previously known species ofFroesia are revised.     

Revision of the genus philactis (Compositae)

Philactis (Compositae-Heliantheae) is a genus of three species, all of limited distribution. A revision is presented, based upon herbarium specimens and field work. Cytological data are from bud material fixed in the field, and from root tips of seedlings. The basic chromosome number appears to be 14.P. nelsonii andP. liebmannii are tetraploid (2n = 56), andP. zinnioides is hexaploid (2n = 84).     

Revision of the genus Fascicularia Mez (Bromeliaceae)

The genus Fascicularia Mez is revised as part of a study of the Bromeliaceae for the Flora de Chile. Morphological and anatomical investigation of herbarium and living material from cultivation as well as DNA-studies (RAPDs) in cultivated material has led us to conclude that Fascicularia bicolor (Ruiz & Pav.) Mez, the only one species in the genus, comprises two subspecies which are distinguished by their leaf anatomy and morphology.     

Revision of the genus Clibadium (Asteraceae, Heliantheae)

Clibadium L. (Asteraceae, Heliantheae) is a genus of 29 species distributed throughout latin America, from Mexico to Peru, and in the West Indies, with high numbers of species in Costa Rica, Colombia, and Ecuador.Clibadium includes shrubs and small trees; usually with loosely aggregated capitula; herbaceous phyllaries arranged in 1–5 series; receptacles usually paleaceous throughout; corollas of pistillate florets 2–4-lobed; corollas of the staminate florets 4–5-lobed; purple to black anthers; and chromosome numbers alln=16. Two sections of species previously recognized are here considered as subgenera (subg.Paleata and subg.Clibadium) containing two and four sections, respectively.Clibadium subg.Paleata contains five species distributed in sects.Eggersia (3 spp.) andTrixidium (2 spp.), and subg.Clibadium has 24 species distributed among sects.Clibadium (6 spp.),Glomerata (9 spp.),Grandifolia (5 spp.), andOswalda (4 spp.).     

Revision of the southeast Asian genus Trivalvaria (Annonaceae)

The number of species in Trivalvaria is reduced from eight to four. A new variety of T. macrophylla from North Sumatra is described. Two Polyalthia species, P. nemoralis and P. oligogyna, found in Laos, North Vietnam, and Hainan, are brought into the synonymy of Z dubia. The genus further ranges from NE India and the Andarnan Islands to Java and Borneo. It is distinguished from other Asian Annonaceae by the characteristic venation of the leaves, the imbricate sepals and petals, and the single basal ovule.     

Revision of the genus Clathrina (Porifera, Calcarea)

The genus Clathrina has one of the most difficult systematic arrangements in the Porifera, Class Calcarea. Few morphological characters can be used to describe its species, and the systematics and the geographical distribution of its species have changed several times, according to the point of view of the systematists. 'Lumpers' consider that clathrinas are morphologically plastic, while 'splitters' believe that even slight morphological differences should be considered sufficient to distinguish between species. The morphology of several specimens/species of Clathrina , including the type species, when possible, was studied and used to produce the first revision of this genus. Using results obtained from previous morphological and molecular studies, the morphological characters were chosen and analysed in all studied specimens. In total, 43 species were found, nine of which are new to science. These results agree with the viewpoint that morphological characters such as type and distribution of spicules, size of actines, spines, anastomosis of the cormus, organization of the osculum and presence of granules in cells, are useful when establishing the taxonomy of the genus.  © 2003 The Linnean Society of London, Zoological Journal of the Linnean Society , 2003, 139 , 1−62.     

Revision of the southeast Asian genus Sageraea (Annonaceae)

Sageraea consists of 9 species, two of which are newly described: S. sarawakensis from Sarawak and S. zeylanica from Sri Lanka. Its distribution ranges from India to the Philippines and Indonesia. Sageraea is closely related to Stelechocarpus , with which it shares the imbricate aestivation of the sepals and petals. Further characteristics are the usually glabrous plants, the coriaceous leaves, the thick, fleshy stamens, and ovules or seeds in 2 series.     

Revision of genus Argyrophenga (Lepidoptera: Satyridae)

Abstract

The endemic New Zealand genus Argyrophenga Doubleday is revised. The genus is shown to consist of three species, antipodum Doubleday, harrisi n.sp., and janitae n.sp. Wing pattern, wing coloration, and male genitalia of all species are described and illustrated. Keys to species are given for both sexes. Taxonomic conclusions are supported by biometric and distributional data. Flight behaviour is described. A brief comparison is made between Argyrophenga and the other endemic New Zealand satyrid genera.
