The number of species of flowering plants is estimated to be in the range of 250,000 to 400,000. This compares to around 12,000 species of moss or 11,000 species of pteridophytes, showing that the flowering plants are much more diverse. The number of families in APG (1998) was 462. In APG II (2003) it is not settled; at maximum it is 457, but within this number there are 55 optional segregates, so that the minimum number of families in this system is 402. In APG III (2009) there are 415 families.
How many families are in AGP III?

Working closely in conjunction with the definition of the Near East provided by the State Department is the Near East South Asia Center for Strategic Studies (NESA), an educational institution of the United States Department of Defense. It teaches courses and holds seminars and workshops for government officials and military officers who will work or are working within its region. As the name indicates, that region is a combination of State Department regions; however, NESA is careful to identify the State Department region. As its Near East is not different from the State Department's it does not appear in the table. Its name, however, is not entirely accurate. For example, its region includes Mauritania, a member of the State Department's Africa (Sub-Sahara).
What does NESA Teach?
