TAXONOMY PLANT COLLECTION  


 This is, I believe, one of the few plant collections, based on taxonomy. It contains one plant from each of the twenty-two classes of Plantae, accordantly to my Taxonomy Tree. This means that I have the most unrelated plant collection that it is possible to have.
 
 WHY? It all started with a caudiciform collection that grew too large. I reduced it by limiting it to one plant from each family. After some time I found I had discovered 99 Families, and had been able to get a representative plant from 95 of these.
 Once again I reduced the collection: Firstly, I tried limitation by Orders, but that only cut it down to 46 plants. So, I reduced it further to Classes. The Sub-Kingdom TRACHEOBIONTA comprises 17 Classes. My caudiciform collection contained 11 of these. With the 5 Classes from the Mosses, I would have the entire kingdom! (Some include the 13 Classes of green algae - I don't).
 My former caudiciform collection now forms a special part of the Copenhagen Botanical Garden. More about how plants are divided into groups on TAXON.
   HOW? I'm working on a way to keep the plants alive and healthy, and, have the freedom to leave them unattended for several weeks at a time. They are divided in to two groups by water needs. Certain bowls contain a special, hidden, interior which allows just the right amount of water up to the soil. Another system keeps the bottom of the bowls filled with water to an even level.
 It is my belief that plants, in general, benefit from a constant level of humidity in the soil. In this way they are able to extend their roots to the levels that suit them best. Maintaining moisture levels in the capillary root system between watering sessions, prevents drowning and rotting, often caused by infrequent and heavier watering. In the wild, moisture is more constant than in pots, and I try to duplicate this. I am convinced that, ‘a little water often’, is better than ‘drowning them occasionally’.
   TREE!  Taxonomy systems constantly changes, and recently, DNA sequences of three genes have made it possible to create a taxonomy tree, resembling the evolutionary tree. I have used the last systems with Classes: Bryophytes: Cavalier-Smith, 1998. Pteridophytes and Spermatophytes: Reveal, 1996.
 The new systems, based on PholyCode, divides the plants accordantly to DNA code from three genes.
 APG is the main source, and their main groups are clades: Angiosperms: Magnoliids (
Gyrocarpus), Monocots (Dioscorea), Commelinids (Amorphophallus), Eudicots (Stephania, Core Eudicots (Delosperma), Rosids (Monolena), Eurosids I (Kedrostis), Eurosids II (Jacaratia), Asterids (Agapetes), Euasterids I (Fockea) and Euasterids II (Cussonia). Welwitschiales and Ephedrales are now part of Gnetales.

WET Section
Anthocerotopsida, Hepatopsida, Bryopsida, and Sphagnopsida. Psilotopsida,
 Equisetopsida, Lycopodiopsida, Selaginellopsida, Isoetopsida, Pinopsida, Piperopsida and Ranunculopsida

DRY Section
Polypodiopsida, Welwitschiopsida ,Ginkgoopsida, Ephedropsida, Cycadopsida, Gnetopsida, Andreaeopsida, Rosopsida, Magnoliopsida and Liliopsida.
To add a bit to the difficulty, I go for the smallest members of each class.

Non-vascular plants - Mosses. Vascular spore plants - Fern and allied. Plants with naked seeds - Gymnosperms. The flowering plants - Angiosperms.

 These is the taxonomy of all the plants I have.
 Bryophyta: Cavalier-Smith, 1998. Tracheophyta: Reveal, 1996.
