Both complete and incomplete flowers are abundant among flowering plants. Incomplete flowers lack one or more of the four components found in complete flowers. There is not a specific lacking component shared between all incomplete flowers. For instance, elm trees lack both petals and sepals, while...
Summary: Plants with Crassulacean acid metabolism (CAM) have long been associated with a specialized anatomy, including succulence and thick photosynthetic tissues. Firm, quantitative boundaries between non‐CAM and CAM plants have yet to be established – if they indeed exist.Using novel compu...

The gynoecium, located in the fourth and innermost whorl of a flower, is the female reproductive organ of flowering plants which has specialized functions for successful pollination, seed maturation and seed dispersal. Although it is a highly complex organ that differs widely in form between species...

SUMMARYConclusions reached by Young(1981) concerning the evolutionary status of homoxyly in woody Angiosperms are biassed because the results of his analyses are based upon the silent acceptance of certain postulates and on assumptions emanating from such current but most probably untenable tenets. ...
studies of pollination are invaluable for understanding the evolution of flowering plants and their distribution in the world today. As sedentary organisms, plants usually must enlist the services of external agents for pollen transport. In flowering plants, these are (roughly in order of diminishing ...
petal, inflowering plants, a sterile floral part that usually functions as a visuallyconspicuouselement of aflower. Petals are modifiedleavesand are often brightly coloured to attract specificpollinatorsto the flower. Petals often come in multiples of three inmonocotsor in multiples of four or five...
inflorescence, in a flowering plant, a cluster of flowers on a branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (peduncle) and by the timing of its flowering (determinate and indeterminate)....
