Sphagnum moss has very a distinctive structure resembling netting or webbing visible in the leaves and shown here in the antheridium. The same pattern is seen here in a sphagnum leaf.

The antheridium resemble peacock feathers. The abundance of similarities between all living things at all scales is mind blowing.

Bryophyte Landscape

This moonly image is a small portion of antheridium of sphagnum moss. Today I am playing with using multiple images displaced into landscape scenes. It’s a theme I’ve been trying to incorporate into my printmaking class with mixed results.

Embryonic Illusions

These images are manipulations of slides of embryonic development in a dicot angiosperm. The long and rounded multicellular structures are cotyledons, structures that resemble leaves, but only persist long enough to support the developing embryo and perhaps the young germinating plant by providing nutrition.
There appear to be tiny people in my cotyledon slides.

Asteraceae

Image

Asters belong to the family Asteraceae, a grouping distinguished by their inflorescence. The flowers are arranged in a head (captitulum). In the aster, many disc flowers are surrounded by many ray flowers which each have one petal. Asters exhibit radial symmetry, but what would they look like if they had bilateral symmetry?

Salvia gregii is a member of the mint family, lamiaceae. Distinguishing features of this family include flowers exhibiting bilateral symmetry, aromatic compounds, and most interestingly square stems. In addition to mint this family includes basil, lavender, thyme, salvias, and rosemary.

S. gregii is a salvia. When the keel is depressed, two stamen and one forked stigma are exposed. The forked stigma, when sticking out, it looks like the tongue of a dragon. The stamen are fused to the corolla (petals) while the style is free, attached to the ovary.

tracheophyte

The fern gametophyte, the prothallus, houses both archegonium and antheridia. The sperm requires water to swim to the archegonia for fertilization to occur. Even though ferns are land plants, free water is required for fertilization. The sporophyte grows on the gametophyte which eventually disintegrates.
