Application of soft X-ray microradiography to observation of cystoliths in the leaves of various higher plants
Soft X-ray microradiography was applied to observation of the cystoliths, calcified bodies of higher plants, in the leaves ofMorus bombycis, Humulus scandens, Ficus elastica, F. retusa (Moraceae),Boehmeria platan...

Calcification in Higher Plants with Special Reference to Cystoliths
The cystolith, a calcified body in the leaf of higher plants, was observed by soft X-ray microradiography using the mature leaves of nine species from five families. The microradiographs revealed very large ci...

Karyomorphology ofCrossostylis (Rhizophoraceae)
We present the first report on somatic chromosome numbers and morphology in eight of 13 recorded species ofCrossostylis, one of inland genera of Rhizophoraceae. The chromosome number ofCrossostylis is 2n=28 in al...

Seed coat anatomy ofCrossostylis (Rhizophoraceae): its evolutionary and systematic implications
The seed coat structure of all 13 species ofCrossostylis was studied to contribute to an understanding of species delimitation and relationships within the genus. The mature seed coat is relatively uniform and co...

Silicon-accumulating idioblasts in leaves of Cecropiaceae (Urticales)
A survey of the structure and mineral composition of leaf idioblasts in the Cecropiaceae was conducted. In all six genera of the family, idioblasts usually occur as trichomes or enlarged epidermal cells and ne...

Phylogenetic relationships inCrossostylis (Rhizophoraceae) inferred from restriction site variation of chloroplast DNA
Phylogenetic relationships among the nine species ofCrossostylis (Rhizophoraceae) were elucidated using cladistic analysis of restriction site variations of chloroplast DNA. As a result, this genus was found to c...

Phylogeny of the family hydrocharitaceae inferred fromrbcL andmatK gene sequence data
The family Hydrocharitaceae, with 15 genera and ca. 80 species, shows a remarkable morphological diversity which presumably developed as an adaptation to their aquatic habitat. This is particularly true in the...

Molecular phylogeny ofNothofagus (Nothofagaceae) based on theatpB-rbcL intergenic spacer of the chloroplast DNA
The genusNothofagus is distributed in the Southern Hemisphere from South America to Oceania, and its distribution has been assumed to be formed by continental drift by means of Gondwana break-up during the Mesozo...
