The orchids known today make up one of the largest Angiospermous families in the world. Recent estimates place the number of genera at about 450 which estimates between 10,000 and 15,000 species (some authorities go as high as 20,000). They are without doubt one of the most highly specialized groups of green plants. Botanically the flowers are of more than passing interest for they deviate so distinctly from the norm of the Monocots. They are the possessors of a number of unique structures that are found in no other family of flowering plants.
