Arceuthobium pusillum

Eastern dwarf mistletoe

Adaptation

 

  The Arceuthobium pusillum is one of the smallest and evolutionary advanced plants.  It has adapted extremely well for its habitat and surrounding environment ensuring the continued existence of the species.  In order to parasitize its host organism the eastern dwarf mistletoe has adopted a root-like system similar to fungi, called an endophytic system.  This network of hyphae  penetrate the host trees bark and eventually anchors itself in the wood of the tree, and penetrates the xylem and the phloem of the host tree without damaging it. More on the endophytic system will be explained in Nutrition section.

 Immature fruits of Eastern dwarf mistletoe;USDA Forest Service - Forest Health Protection - St. Paul Archive, USDA Forest Service, www.forestryimages.org Although this organism cannot move it has developed an extremely bizzare means of ensuring the spread of its seed.  When the seeds are ready for discharge they are forcefully shot from the female plant using built up water pressure.  The seeds can reach distances of up to 55 ft (16.5m) and obtain speeds of close to 55 mph.  And if this wasn't enough the seeds are coated in gooey sticky gel that allows the seed to stick to anything that it may come into contact with (i.e. another branch, a different tree, or even an animal).  But more on that under Life History.
