ABC Plus Model of the Genetic Control of Flowers

ABC genes, sepallata and leafy genes and how they interact to direct organ formation in flowers

Araceae, Liliaceae, Uvulariaceae, Trilliceae

The Araceae and the petaloid monocots.

Amaryllidaceae, Alliaceae, Ruscaceae and Iridaceae

This covers four more monocot families.

Origins of Angiosperms

Looks at some of the trees that focus on the earliest angiosperms.

Early Land Plants

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.

Evolution of the Seed

This covers the evolution of the seed including examples of seeds and pictures of the cycads, ginkgos and conifers.

Fossil Angiosperms

This covers fossil flowers, the saga of Archaefructus and Brachyceran flies and what they tell us about angiosperm evolution.

Gnetophytes

This covers pictures of the bizzare Welwitchia, Ephedra and Gnetum. It also has images of the tallest, most massive and longest lived trees.

Introduction to the Angiosperms

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.

Free-sporing Tracheophytes

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!

Magnoliaceae & Illiciaceae

This covers two basal angiosperm groups: the Magnoliaceae and teh Illiciaceae.

Monocots vs. Dicots

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”.

Orchids

Orchidaceae

Origami Leaves & Magnoliids

This covers origami leaves, the Magnoliaceae, Lauraceae and Piperaceae.

Poales

Juncaceae, Cyperaceae, Poaceae.

Pollen Tubes, Stigmatic Papillae, S-Locus Function

S-allele systems, Pollen Tubes, Stigmatic Papillae, Synergids and the 4-celled embryo sacs.

Speciation

New species can form from changes in breeding systems, temporal separation, pollinator shifts or by polyploidy.
