Parts of plant. Structure of Clubmoss or Lycopodium (Running clubmoss or Lycopodium clavatum
ADVERTISEMENTS: In this article we will discuss about the structure of Lycopodium with the help of diagrams. The main plant body is sporophytic. It consists of slender and branched stem, numerous small leaves (microphylls) and dichotomously- branched roots (Fig. 7.23A, B). Roots: ADVERTISEMENTS: The primary root or first formed root of the young sporophyte is […]

2. Cortex: 3 layers in L.cerenuum 3. Outer and inner cortex is parenchymatous and middle cortex is sclerenchymatous 4. Endodermis: single layered, often with casparian thickening 5. Pericycle: One to many layered made up of parenchymatous cells 6. Stele: basically protostele Varies in different species:

Observe fresh specimens and prepared slides of Selaginella and/or Lycopodium. Draw and describe the important characteristics that differentiate these plants from bryophytes, including stem and leaf structure, below ground parts, and where spores are produced.

In this article we will discuss about the anatomy of lycopodium. Also study the strobilus, arrangement of sporangia, L.S. strobilus and spores of lycopodium. Cut thin transverse sections of stem, leaf and root by inserting the material in pith, stain in safranin- fast green combination, mount in glycerine and study- under microscope. Stem: 1.

Lycopodium (from Greek lykos, wolf and podion, diminutive of pous, foot) [2] is a genus of clubmosses, also known as ground pines or creeping cedars, [3] in the family Lycopodiaceae. Two very different circumscriptions of the genus are in use.

Lycopodium clavatum (Fig. 538A) is a temperate to sub- tropical, terrestrial species very common on the Indian hills, specially the Himalayas. The sporophyte has a weak, prostrate stem trailing along the surface and rooted down with adventitious roots growing anywhere on the lower surface.

Figure 6.1.1. 1: A preserved Lycopodium gametophyte. The flat thallus extending out to the right is the gametophyte. The sporophyte emerges from its left side, the root system developing downward and shoot system developing upward. This gametophyte would normally be green and photosynthetic, but the pigments were lost in the preservation process.

The Epidermis of the stem typically has Stomata. The outer Cortex usually contains Chlorenchyma. This photosynthetic tissue may contain a lot of air spaces & can be continuous with the leaves. The take home message is that the stems can make a major contribution to the total amount of photosynthesis that takes place in Lycopodium.

Lycopodium cernuum Strobili. Plant body is the sporophyte. Differentiated into root, stem and leaves. Considering the variation in habit of different species, Pritzel (1900) divided the genus Lycopodium into two sub-genera: Urostachya. Rhopalostachya. Erect or pendant stem. Stem-Dichotomously branched. Roots arise only from base of stem.

Asexual propogation of sporophytes can occur via an underground stem that travels horizontally, called a rhizome. Figure 2.5.3.1.3 2.5.3.1. 3: A Lycopodium sporophyte growing vegetatively. The branches occur in Y-formations, showing dichotomous branching. There are many small, thin leaves (microphylls).

Lycopodium is homosporous and the spores are produced within large, short-stalked, reniform to somewhat sub-globose sporangia, borne singly either in the axils or on the stem, a little above the sporophylls.
