We evaluated this hypothesis in the context of a phylogeny of 918 monocotyledons assembled from 19 published trees. Binary and multistate breeding system characters were mapped onto a set of composite trees, and alternative models of character change were compared using maximum likelihood. Over a range of tree topologies and optimizations, we found three to eigth times as many changes from hermaphroditism to dioecy as we did from monoecy to dioecy. Also, the rate at which monoecy gave rise to dioecy was not significantly higher than the rate at which hermaphroditism gave rise to dioecy. Our analysis implies that the correlation of monoecy and dioecy in angiosperm families does not reflect a preponderance of changes from monoecy to dioecy. Instead, we postulate that the family-level correlation results from the clustering of breeding systems changes in the underlying phylogeny. Our results suggest renewed attention to modeling the transition from hermaphroditism to dioecy, possibly involving transient intermediates such as gynodioecy.}, keywords = {breeding systems, dioecy, monocotyledons, phylogeny, parsimony, maximum likelihood}, author = {Weiblen, George D. and Oyama, Ryan K. and Donoghue, Michael J.} } @article {324, title = {Distribution of Triglochin maritimum (Juncaginaceae) in Poland}, journal = {Fragm.

The main reason for the proposal lies in the different and partly independent developmental patterns of the periath/androecial and the gynoecial components of the flower. In many cases in the Zosterales, e.g. Triglochin, Lilaea, Potamogeton, and Scheuchzeria, there is stamen/tepal superposition: each stamen is formed above a perianth member in a way suggesting an axillary relationship, and the set of organs occur in whorls of different numbers according to the taxon. Similarly, in the Alismataceae and related families, the perianth members occur in whorls of three, and there is commonly an association between a petal and a superposed pair of stamens which develop in association with it, often from what appears to be a common primordium. Further stamens may be initiated above (some Alismataceae) or below (Hydrocleis) the firstformed stamens. In all these cases carpels are initiated in what seems initially to be a whorled pattern above the androecium, with the numbers in a whorl corresponding to those in the perianth. However, it has been shown in Potamogeton and Ruppia that carpel positioning is more flexible and appears to operate like an ordinary phyllotactic system. The flowers can be seen as being made up of two different types of module, one being the perianth/stamen complex, and the other the carpel. We now have additional data for floral development in two genera of Alismataceae, Luronium and Wiesneria, which complement older data and seem to reinforce the concept of independence of development in the two regions. Phylogenetic analysis indicates these genera are in interesting position within Alismataceae: Luronium is near other genera showing some range of gynoecial organisation, and Wiesneria is part of a complex including Sagittaria which shows extreme variation in meristic complexity.}, keywords = {Helobial, flowers, development, evolution, Alismatidae, Alismataceae, monocots}, author = {Posluszny, Usher and Charlton, W.

Flower development and anatomy of Acorus calamus and flower anatomy of A. gramineus were studied. Findings were compared with published reports on paleoherbs. Important developmental features include an abaxially median tepal that is initiated first and is similar to a flower-subtending bract and unidirectional flower development with an inversion of organ initiation sequence in the second tepal whorl. The mature gynoecium is largely synascidiate, but early development of carpels is plicate, and the apocarpous portion persists up to anthesis. The carpels form dorsal bulges on the style, enclosing longitudinal intercarpellary slits. The dominance of the synascidiate portion and the apical position of the placenta result from a late and distinct basal elongation of the gynoecium. Stigma, pollen transmitting tract, and ovary are filled with secretion. Secretory papillae are present from the stigma to the placenta; papillae also occur on the rims of the integuments of the ovules. In the uppermost part of the inflorescence, the adaxial floral sectors are reduced in number and structure, and at the apex of the inflorescence, a peloria-like structure is formed. Developmental and morphological similarities seem to be closer between Acorus and Piperales than between Acorus and other magnoliids.
