  4. 4. Selaginella lepidophylla  Called the Resurrection Plant, this plant can turn from a dried up ball into a leafy green plant overnight by soaking in water. It is native to Arizona and Texas.
  5. 5. Equisetum hyemale  This horsetail is a primitive vascular plant.  It is also called a scouring rush because the stems used to be used to clean pots and pans.
  6. 6. Lycopodium clavatum  A club moss native to Oregon.  It has only one kind of spore, a condition termed homosporous
  7. 7. Cycas rumphii  Commonly known as Queen Sago.  It is a small tree that grows about 10 m in height.  It is part of a species comples.
  8. 8. Ginkgo biloba  Common name: Maidenhair tree  This is the only species of the Phylum Ginkgophyta.  It is a large tree that has deciduous fanlike leaves.  It is popular in cities for it tolerates pollution well.

  15. 15. Psilotum nudum  This is whisk fern of the phylum pterophyta commonly called Skeleton Fork Fern.  It has no roots.  It is considered a primitive plant, possibly a descendent of the first vascular plants.
  16. 16. Wollemia nobilis  An evergreen tree known commonly as the Wallemi pine. It is a survivor of a conifer group once known only from fossils.  It was discovered in 1994 in a national park in Sydney, Australia.  It consists of merely 40 known individuals.
