ABC genes, sepallata and leafy genes and how they interact to direct organ formation in flowers
The Araceae and the petaloid monocots.
This covers four more monocot families.
Looks at some of the trees that focus on the earliest angiosperms.
This covers the liverworts and the evidence that they were the first land plants (Qiu's tree). It also has the main innovations plants made when they moved to land, the life cycle of Chara and ferns, trends in the reduction of the gametophytic stage and Kendrick and Crane's tree summarizing early plant evolution.
This covers the evolution of the seed including examples of seeds and pictures of the cycads, ginkgos and conifers.
This covers fossil flowers, the saga of Archaefructus and Brachyceran flies and what they tell us about angiosperm evolution.
This covers pictures of the bizzare Welwitchia, Ephedra and Gnetum. It also has images of the tallest, most massive and longest lived trees.
This covers patterns of diversification, Darwin's abominable mystery, morphological series showing link of floral organs to leaves, pollen diversity, raphides in Impatiens, male and female gametophytes.
This covers the lycophytes, equisetophytes, psilophytes and the ferns. It also covers the evolution of the megaphyll and has pictures of a couple of botanical jokes!
This covers two basal angiosperm groups: the Magnoliaceae and teh Illiciaceae.
This shows the fundamental differences between monocots and dicots, but keep in mind that although the monocots are monophyletic, the dicots are not, and some even advocate getting rid of the term “dicot”.
Orchidaceae
This covers origami leaves, the Magnoliaceae, Lauraceae and Piperaceae.
Juncaceae, Cyperaceae, Poaceae.
S-allele systems, Pollen Tubes, Stigmatic Papillae, Synergids and the 4-celled embryo sacs.
New species can form from changes in breeding systems, temporal separation, pollinator shifts or by polyploidy.
