Sympodial structure of spikelets in the tribe Schoeneae (Cyperaceae).
Spikelet morphology of 250 specimens of 47 species of Schoeneae was examined using light microscopy and scanning electron microscopy. We confirmed that spikelet structure in Schoeneae is cymose with a sympodial "rachilla." Monopodial spikelets, as described by most current literature, were not found in Schoeneae. Prophylls are not always present in sympodial spikelets and cannot be used to dete...
متن کاملSedges in the mist: A new species of Lepidosperma (Cyperaceae, Schoeneae) from the mountains of Tasmania
The status of a putative new species of Lepidosperma from the mountains of south-western Tasmania, Australia, was investigated. Phenetic analysis (Flexible UPGMA Agglomerative Hierarchical Fusion and semi-strong hybrid multidimensional scaling) was conducted on a database derived from morphological and anatomical characters scored from herbarium material, culm anatomy slides and scanning electr...
متن کاملon translation of phatic communion and socio-cultural relationships between the characters of the novels
phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
15 صفحه اولSpecies Delimitation and Interspecific Relationships of the Genus Orychophragmus (Brassicaceae) Inferred from Whole Chloroplast Genomes
Genetic variations from few chloroplast DNA fragments show lower discriminatory power in the delimitation of closely related species and less resolution ability in discerning interspecific relationships than from nrITS. Here we use Orychophragmus (Brassicaceae) as a model system to test the hypothesis that the whole chloroplast genomes (plastomes), with accumulation of more variations despite t...
متن کاملRevision of Afro-Malagasy Otomops (Chiroptera: Molossidae) with the description of a new Afro-Arabian species.
The paucity of data for the molossid bat Otomops throughout its range has hindered our ability to resolve the number of Otomops species present within the Afro-Malagasy region (including the Arabian Peninsula). This paper employed an integrative approach by combining morphometric (cranial morphology) and molecular (mitochondrial cytochrome b and D-loop sequences, nuclear intron sequences and mi...
