Taxonomy

• Division Lycophyta – club mossesLycopodium and Selaginella* microphylls* one sporangium per sporophyll

• Division Sphenophyta – horsetails* microphylls (not photosynthetic)* sporangia clustered into strobili

• Division Polypodiophyta – fernsaka Pteridophyta* megaphylls* many sporangia per sporophyll

Page 3: Botany Lab Prep SEEDLESS VASCULAR PLANTS BIO 201 - BOTANY.

Lycophyta - Lycopodium

• True vascular tissue (root, stem, leaf)

• Leaves as microphylls

Page 4: Botany Lab Prep SEEDLESS VASCULAR PLANTS BIO 201 - BOTANY.

Lycopodium

• All microphylls alike

• Spores on microphylls or strobili

Page 5: Botany Lab Prep SEEDLESS VASCULAR PLANTS BIO 201 - BOTANY.

Lycophyta - Selaginella

• Anisphyllous microphylls

• Stobili present
