1 Club Mosses, Ferns & Horsetails: the Seed-free Vascular Plants
2 Vascular Plants - a quick review Two unrelated groups within cryptogams seed free vascular plants are recognized as phyla: 1. Lycopodiophyta : lycopods 2. Polypodiophyta: ferns, horsetails, and whisk ferns
3 Vascular Plants - a quick review Why were the seed-free plants grouped together? They produce free spores, the principal dispersal units, via meiosis. Spore: a reproductive cell, capable of developing into an adult without fusion with another cell. spores
4 Vascular Plants - a quick review Why were the seed-free plants grouped together? Spores develop within a sporangium (pl. sporangia) sporangium spores
5 Vascular Plants - a quick review Why were the seed-free plants grouped together? Spores germinate and develop into gametophytes that exist independently of the spore-producing plants. The gametophytes (haploid, n) tend to be inconspicuous and short-lived. sporangium gametophyte spores
6 Vascular Plants - a quick review Why were the seed-free plants grouped together? Like all plants, seed-free plants produce two kinds of gametes in their gametophytes: sperm and egg that unite to form a zygote (2n or diploid) via fertilization! sporangium zygote gametophyte spores
7 Vascular Plants - a quick review Why were the seed-free plants grouped together? The sporophyte (2n) develops from the zygote and is more conspicuous, usually perennial and lives for an indefinite period! sporophyte sporangium zygote gametophyte spores

9 Wisconsin Seed-free Plants The best manual to identify lycopods and ferns is Ferns of Northeastern and Central North America (2 nd ed.) in the Peterson Field Guides Warning: Families and genera (and thus species names) are changing quickly in the seed-free plants
10 Phylum Lycopodiophyta club mosses, spike mosses, quillworts! Leaves microphylls: generally small, simple, one-veined leaves. Microphylls evolved by the process of enation and vascularization. An enation is a veinless, lateral protrubence on the stem. When the enation becomes vascularized it is termed a microphyll.! Sporangia: the spore producers on the sporophytes are located singly on the upper surfaces or in axils of the bracts of a cone or of green leaves!
11 Phylum Lycopodiophyta! Carboniferous forest from Illinois This group arose in the Later Silurian about 420 million years ago and was dominant in the Carboniferous and used to be much more diverse.!
12 Phylum Lycopodiophyta! Lycopodiaceae - club mosses 15 genera and about 375 species Lycopodium now split into several genera cosmopolitan distribution, most diverse in tropics Evergreen, stems elongate and dichotomously branching. Leaves often densely covering the stem. Oily compounds in the cell walls ignite rapidly into a flash of light and were used by magicians and sorcerers in the Middle Ages. More recently they were used as a flash early in photography and in experimental photocopying machines. Many species over-collected for Christmas wreaths. Diphasiastrum complanatum Ground cedar, crowfoot

Spores borne in or near the axils of well-differentiated sprophylls, usually on 4 sided stroboli. Heterosporous: different spores!! Unlike Lycopodiaceae, Selaginellaceae are heterosporous with different types of spores: microspores and megaspore (not related to size) the micro give rise to male gametophytes and the mega give rise to the female gametophytes.
21 Selaginellaceae - spike mosses Phylum Lycopodiophyta! Heterosporous: different spores!! Unlike Lycopodiaceae, Selaginellaceae are heterosporous with different types of spores: microspores and megaspore (not related to size) the micro give rise to male gametophytes and the mega give rise to the female gametophytes.
24 Isoetaceae - quillworts Phylum Lycopodiophyta! 1 genus and about 150 species; worldwide; 2 spp. in WI - Isoetes echinospora most common Aquatic or semi-aquatic plants with corm-like stems with secondary growth.

25 Isoetaceae - quillworts Phylum Lycopodiophyta! Heterosporous plants with sporangia borne at the base of sporophylls which are similar to vegetative leaves. Megasporangia + microsporangia
26 Phylum Polypodiophyta - ferns & horsetails! Equisetaceae - horsetails, scouring rushes [previously placed in own phylum - Equisetophyta] 1 genus, Equisetum, 15 species with a cosmopolitan distribution except for Australia or New Zealand [9 species in Wisconsin] Plants are primarily colonizers of unforested areas, lake margins and wetlands Shoots monomorphic or dimorphic (see right). Often highly branched (horsetails) appearing like leaves. Others not branched (scouring rushes). Internodes with conspicuous vertical ridges; jointed stems; stems hollow (both important taxonomic features for keying species)
27 Equisetaceae - horsetails, scouring rushes Phylum Polypodiophyta! Leaves in whorls; leaves one veined, verticillate, united to form a sheath around the stem; these leaves are probably reduced megaphylls: Megaphylls are larger than microphylls have a blade that has a complex system of veins. megaphyll sheath branch Megaphyll theory is supported by placement of Equisetum among primitive ferns using DNA.
28 Equisetaceae - horsetails, scouring rushes Phylum Polypodiophyta! Sporangia clustered terminally in cones composed of polygonal, umbrella-like structures with sporangia beneath.
29 Equisetaceae - horsetails, scouring rushes Phylum Polypodiophyta! Horsetails are homosporous, have green spores with hygroscopic elators, and form conspicuous green gametophytes

32 Phylum Polypodiophyta the true ferns! Most diverse of the vascular cryptogams, both in species number (ca. 11,000 worldwide) and form (small aquatics to trees). Like the horsetails (which may be thought of as specialized ferns), leaves are megaphylls; blade is called a frond and the petioles as stipes.
33 Phylum Polypodiophyta ferns! Circinate vernation: vernation is the arrangement of folded leaves in a bud, forming a crozier or fiddlehead, i.e. coiled or rolled up at the tip and unfolding lengthwise when emerging - due to auxin and differential growth of tissue. Protects young bud.
34 Phylum Polypodiophyta ferns! Sporangia borne on the margin or the lower surface of the leaf; often grouped in sori (pl.) sorus (sing.); a sorus may be protected by a flap-like structure called the indusium - an important feature for identification of ferns due to its remarkable variation in size, shape, and position.
35 Phylum Polypodiophyta ferns! The sprorangium is often associated with an annulus a cluster or row of cells with thick walls that open the sporangium and catapult the spores into the air. Ferns can be either homosporous or heterosporous. annulus
36 Phylum Polypodiophyta ferns!
37 Phylum Polypodiophyta! There is major disagreement on what are the fern families, but 30 are generally recognized worldwide. In Wisconsin there are 9 families. Characters used to circumscribe families often relate to cryptic features such as the presence or absence of annulus and its orientation, the length and diameter (number of cells) of the sporangial stalk, spore shape, stem and petiole crosssection anatomy. The primitive ferns include horsetails and whiskferns.
38 Phylum Polypodiophyta! Ophioglossaceae - adder s tongue family Primitive ferns; 2 genera in Wisconsin: Ophioglossum and Botrychium (now 3 genera) Sporangia are on an erect axis with a green blade attached below the sporangia bearing part Ophioglossum pusillum Adder s tongue fern
