Syncyte formation in the microsporangium of Chrysanthemum (Asteraceae): a pathway to infraspecific polyploidy
Polyploidy, which is thought to have played an important role in plant evolution and speciation, is prevalent in Chrysanthemum (x = 9). In fact, polyploid series are known in C. zawadskii (2x, 4x,… Expand
Embryology of Amborella (Amborellaceae): Descriptions and Polarity of Character States
Amborella trichopoda Baill. which, based on recent analyses of multiple genes, was identified as the first branch in the angiosperm evolution. Comparisons with two other basal angiosperms… Expand

Abstract The flowers of mangrove plants are pollinated by a variety of pollinators including birds, bats, and insects. This study analyzed the floral scent chemistry of mangroves on Iriomote Island… Expand
An embryological analysis of Myrtales : its definition and characteristics
A combination of embryological characteristics clearly defines Myrtales as comprising Combretaceae, Lythraceae (including Punicaceae and Sonneratiaceae), Melastomataceae, Myrtaceae, Onagraceae,… Expand
Mode of pollen-tube growth in Pistils of Myrica rubra (Myricaceae): a comparison with related families.
BACKGROUND AND AIMS It is generally known that fertilization is delayed for more than a few weeks after pollination in Fagales. Recent studies showed that, during that period, pollen tubes grew in… Expand
Phylogenetic analyses of Malpighiales using plastid and nuclear DNA sequences, with particular reference to the embryology of Euphorbiaceae sens. str.
We present phylogenetic analyses of Malpighiales, which are poorly understood with respect to relationships within the order, using sequences from rbcL, atpB, matK and 18SrDNA from 103 genera in 23… Expand

Ovules and Seeds in Subfamily Phyllanthoideae (Euphorbiaceae): Structure and Systematic Implications
Lingelsheimia) are distinct from the rest of the subfamily in having a thick inner integument (over six cells thick), an exotegmen composed of cuboidal cells (type II), and vascular bundles in the… Expand
Phylogenetic Relationships of Betulaceae Based on matK Sequences with Particular Reference to the Position of Ostryopsis
Embryology and relationships of Lauraceae (Laurales)
Abstract Embryology of Lauraceae, hitherto poorly known, was investigated on the basis of 35 species from 23 genera to contribute to a better understanding of familial and generic relationships. Data… Expand
