In this ninth and final part of a revision of the ocypodid genus Macrophthalmus Latreille (Crustacea: Brachyura), eight species are considered— M. leptophthalmus (H. M. Edw.), M. boteltobagoe (Sakai), M. philippinensis SereGne, M. consobrinus Nobili, M. gastrodes Kemp, M. franchettii Maccagno, M. gallardoi SereGne and M. vietnamensis SereGne—and the status of a species previously considered valid, M. holthuisi SereGne, is reconsidered. Only M. leptophthalmus, M. boteltobagoe and M. philippinensis are considered valid. Macrophthalmus , as here revised, contains 38 living and three extinct species, whilst 33 species have been reduced to synonyms. These various species are summarily listed and a key to the living species is provided.  相似文献

Maranta subgen. Maranta includes species related to M. arundinacea L. It is characterized by aerial shoots with a strong monopodial tendency, absence of root tubers, simple inflorescences or few-branched, often diffuse synflorescences, florescences with few, herbaceous spathes, and comparatively large, distinctly pedicellate flowers. There are occasional exceptions to all these characters. Most species are partial selfers, only two or three being allogamous. Sixteen species are recognized, eight of which are new: M. linearis, M. sobolifera, M. lindmanii, M. zingiberina, M. incrassata, M. rupicola, M. amazonica , and M. tuberculata. The new species are described, and all species are defined and discussed, data being given about distribution and habitat. Growth habit and rhizome structure are essential taxonomic characters, but leaf shape and indument distribution are more useful characters for routine identification. Of the species referred to subgen. Automaranta by Schumann in Das Pflanzenreich, three are excluded: M. cordata, M. pohliana , and M. foliosa.  相似文献

Twenty-six species of silica-scaled chrysophytes representing the genera Chrysosphaerella (1 species), Mallomonas (19 species) and Synura (6 species) are reported based on transmission electron microscopy from the springtime flora of the slightly acidic bog-lake Baláta-tó, a Nature Reserve, situated in Southwest Hungary. Ten of them ( Mallomonas alata, M. clavus, M. insignis, M. mangofera, M. oviformis, M. papillosa, M. pillula, M. scalaris, M. transsylvanica and Synura multidentata ) are new records for Hungary. Furthermore, two species, M. pillula and M. scalaris are for the first time found in the Carpathian Basin and M. alata f. hualvensis is a new record for the flora of Europe. Dispersal problems are discussed.  相似文献

ABSTRACT. The Neotropical species of Metopia Meigen are revised, and a total of fifteen species recorded from the region. Five species are described as new; M.aurigans sp.n., M.pulverulenta sp.n., M.hispidimana sp.n., M.flava sp.n., and M.cubitosetigera sp.n. Three species are recorded for the first time from the Neotropical region; M.inermis Allen, 1926, M.krombeini Sabrosky, 1953, and M.sinipalpis Allen, 1926. Four new synonyms are proposed; M.tessellata Allen, 1926, syn.n. of M.perpendicularis Wulp, 1890, M.macrocera Dodge, 1968, syn.n. of M.brasiliana (Townsend, 1929), M.astuta Dodge, 1968, syn.n. of M.brasiliana (Town-send, 1929), and M.lucipeda Reinhard, 1961, syn.n. of M.campestris (Fallen, 1810). Males of M.polita (Townsend, 1935) and M.juquiana (Townsend, 1934) are recorded for the first time. A key to all American species of Metopia is provided, and the phylogenetic affinities of the Neotropical species are briefly discussed.  相似文献

Ecological studies were carried out on 19 endangered populations of Meconopsis horridula, M. paniculata, M. simplicfolia, M. sinuata and M. villosa from the Sikkim Himalayas. The populations of M. horridula, M. paniculata and M. sinuata inhabit open alpine slopes, those of M. simplicfolia are restricted to alpine meadows, while those of M. villosa are confined to the interiors of temperate forests and along forest fringes. The habitats of these species remain snow-hound from October to February. Analyses suggest that all the species except M. horridula , have a broad area of distribution, but narrow habitats and niches. All five species are confined to moist, clayey to silty soils with acidic pH, high concentrations of organic matter, nitrate, phosphate, potassium and calcium. M. paniculata is a 'generalist', whereas all other species investigated are 'specialists'.  相似文献
