Conclusion: In Togo the horticultural flora was rich with 612 species including 20 Pteridophytes
17 Gymnosperms and 575 Angiosperms.
These are symbiotic associations observed in 200 botanical families representing 1,000 genera and about 300,000 plant species  including angiosperms, gymnosperms, pteridophytes
, and some bryophytes with a limited range of fungi belonging to a single order, that of Glomeromycota .
The taxonomic treatments cover pteridophytes
and gymnosperms, dicotyledons, and monocotyledons.
One (1) species was classified as gymnosperm, four (4) were classified as pteridophytes
, and 103 were classified as angiosperms.

Spores of Equisetum dominate among the Pteridophytes
The flora of the Archipelago of San Andres and Providencia has been relatively well studied, and at least two major expeditions have included these islands, the "Fifth George Vanderbilt Expedition" in 1941, and the "Catherwood Chaplin West Indies Expedition" from the Academy of Sciences of Philadelphia in 1948, of which only the Pteridophytes
were published (Proetor, 1950).
