Systematic Embryology of the Anisophylleaceae

The Origin of Diversity in Begonia: Genome Dynamism, Population Processes and Phylogenetic Patterns

“…These numbers indicate that basic chromosome numbers within these families are situated between x = 10 and 13. However, within the basally branching family Anisophylleaceae, chromosome numbers of x = 7 and x = 8 are reported (Tobe & Raven, 1987). The above data suggest a diploid chromosome number for the genus Begonia between 20 and 26; chromosome numbers of 2n = 36 or 38 were probably established after polyploidisation and genome stabilisation early in the evolution of this genus.…”

The Arabidopsis SUPERMAN Gene Mediates Asymmetric Growth of the Outer Integument of Ovules.

“…Because of the relative morphological conservation of ovules within taxa, ovule morphology has proven a useful criterion for phylogenetic analyses within and between angiosperm families and in examination of the relationships between angiosperms and other seed plants (for examples, see Crane, 1985;Tobe and Raven, 1987;Taylor, 1991;Doyle et al, 1994). One of the most distinctive features of ovule morphology used in such studies is the location of the micropyle relative to the funiculus.…”

A monograph of the Anisophylleaceae (Cucurbitales) with description of 18 new species of Anisophyllea

“…Most morphological, anatomical, palynological, embryological, as well as aluminum accumulation studies supported the exclusion of Anisophylleaceae from Rhizophoraceae and concluded that the four genera of Anisophylleaceae are closely related (Behnke 1982, Tobe & Raven 1987b, Dahlgren 1988, Juncosa & Tomlinson 1988a, b, Keating & Randrianasolo 1988, Vezey et al 1988. Most notably, the recent molecular analyses unambiguously confirmed the monophyly of Anisophylleaceae (Zhang et al 2006(Zhang et al , 2007.…”

“…Croizat (1943) and Hutchinson (1973) treated Polygonanthus as a separate family, Polygonanthaceae, based on a study by Baehni & Dansereau (1939) that stressed the distinctness of this genus and suggested that Polygonanthus was a Saxifragaceae. Despite these, there is little doubt, on the basis of morphological and wood anatomical evidence, that Polygonanthus fits well in Anisophylleaceae, together with the three other genera that have traditionally been placed there (see Kuhlmann 1944, Pires & Rodrigues 1971, Tobe & Raven 1987b.…”
