Psilotum 1, 2, 3, 4, 5

XS of Stem - identify all the tissues. 1, 2, 3
XS and LS of sporangium - examine synangium, bracts and enations. 1, 2, 3, 4
Examine specimens in jars and dishes, and living plants.
 

Lycopodium 1, 2, 3, 4, 5, 6, 7

XS of root - identify tissues
XS of rhizome - identify tissues, and stele.
XS and LS of strobilus - identify all parts and structures. 1, 2,3
If gametophytes are available, identify structures.
Specimens in jars and herbarium sheets and living plants are available for identification of parts.
 

Selaginella  1, 2, 3,4

LS and WM of strobilus - identify all parts and structures. 1, 2, 3, 4, 5
Spore (with gametophyte and germinating sporophyte. 1
Specimens in jars, and dried "resurrection fern", and living plants.
 

Isoetes  1, 2, 3

XS of rhizophore/sporophore/corm - identify structures and parts.
Megasporangium 1
Examine specimens in jars or dishes.
 

Equisetum 1, 2, 3, 4, 5, 6, 7

XS of rhizome. Identify all parts, and tissues. Concentrate on one species, but compare with a couple of other species to see how they may vary.
XS of aerial/upright/fertile/sterile stem. Again examine one, but look at several, since there is quite a bit of variation in locations of tissues. Find all tissues, canals, etc. 1
XS and LS of strobilus. Identify all structures. Also dissect a specimen of a mature strobilus under a dissecting scope, and identify structures. 1, 2, 3
WM of spores 1
WM of prothallus with antheridia,

Examine specimens in jars, dishes, herbarium mounts and live plants.

Take a piece of strobilus from the jar indicated, place on a slide under a microscope, and break open some sporangia to release the spores. If your specimen is dry to begin with proceed to the next step. If it is wet, examine the spores, and watch as they dry out.

Now GENTLY breathe on the spores so that the humidity of your breath can be detected by the hygroscopic elaters. Quickly look through the microscope and observe the actions of the spores.
