Robin Jones,Clive Maynard,Ian Stewartbracts, calyxes, awns) which cause the whole diaspore to move on the ground and propel the diaspore in a definite direction (McCann 1959). Trypanospermic or boring fruits are examples of antitelechoric dispersal mechanisms and are equipped with a hygroscopic drilling apparatus or with a sharply pointed tip which enables them to penetrate the soil.

Autochory,ereas others prevent dispersal and are antitelechoric (Fahn and Werker 1972). Ballistic dispersal, a form of telechoric autochory, occurs when the diaspore is propelled explosively, by a fruit that opens suddenly or by a triplever (Willson et al. 1990). It may be due to tension in dead hygroscopic t

Restriction of Dispersal Due to Anchorage Mechanisms,ena differ vastly, the advantages conferred to the species by way of anchorage are similar. Myxospermic diaspores form a superficial layer of mucilage upon moistening, while trypanospermic diaspores have the ability to “drill” (bore) their diaspores into the soil.
