Picture 9 - This is a picture of a fern. Ferns are the most adundant group of seedless vascular plants, with about 11,000 living species. Recent research indicates that they may be the closest relatives to the seed plants. The leaves are referred to as fronds and usually develop at the tip of the rhizome which is a horizontal underground stem with roots emerging from the sides, as tightly rolled up coils.
