THE CLUB-MOSS FAMILY
 
The club-moss family is well represented in Saskatchewan, particularly in northern regions. These herbs prefer the cool temperatures of the boreal forest. Their roots grow from the underside of the creeping stems. The stems are densely leafy and may be branched. The leaves are ranked, that is, they are in vertical rows. The reproductive structure is the sporangium, or spore sac, which releases spores. In this family, there is only one type of spore. The spore sacs are usually arranged into a cone-like structure called a strobilus.
 
INUNDATED CLUBMOSS
 
  LATIN NAME:    Lycopodiella inundata
 
WHAT DOES IT LOOK LIKE?
 
Inundated club moss has only horizontal stems that lie flat on the ground. The leaves are all the same and are 5 to 6 mm long. The leaves are linear to narrowly triangular and are twisted towards the upper side of the stem. The erect cone stalks are also leafy and end in cones 1 to 3 cm long. The sporophylls are very similar to the leaves.
 
WHERE DOES IT GROW?
 
Inundated clubmoss grows in wet bogs, fens, and organic lake shores.
 
WHERE IS IT FOUND IN SASKATCHEWAN?
 
This species is found in northern Saskatchewan in the Athabasca Plain, Churchill River Upland, Selwyn Lake Upland, and Tazin Lake Upland ecoregions.
 
WHY IS IT RARE?
 
Inundated clubmoss is threatened in Saskatchewan because it is rare and regionally restricted to the north. Local population sizes vary. No immediate threats are known at the present time.
 
HOW TO IDENTIFY INUNDATED CLUBMOSS
  * Are the sporophylls similar to the stem leaves?
* Are the stems lying flat on the ground?
* Are the leaves twisted towards the upper side of the stem?
* Did you find it in northern Saskatchewan?
If you answered yes to all of these questions, you may have found inundated clubmoss!
