TaxonomyEquisetales is an Order in the Class
Pteridophyta.
In the
Plant theory Equisetales is the only Order in the Class
Equisetidae. The division in
Subphases is limited as only one family,
Equisetaceae, is surviving at the moment.
Equisetaceae are placed in
Subphase 4. This shows the prominent quality of Silicon, being in
Subphase 4 in the
Silicon series, just as
Equisetaceae is. Equisetum is the plant having the highest content of Silicon of all known plants, up to 80%.
Equisetales shows also the prominent place of
Subphase 4 in general, the Phase that is the strongest, most vital and longest surviving.
Phase 4 is the most alive, showing what it is, without hesitation and retirement.
Subphases4.
Equisetaceae: Equisetum.
IntroductionThey have an emphasis on the
Silicon series beside the quality of the
Iron series.
They have a conflict between their own family and the community. Or they derive the strong family structure from the community.
