Plants by Scientific Name

 

Taxonomic note: Based on phylogenetic analysis, dramatic revisions of structural relationships within the plant kingdom are occuring. This is largely supported by genetic similarilty and the resultant understanding of evolutionary relations, as well as morhologic structure. For more information, consult Plant Systematics, A Phylogenetic Approach by Judd, Campbell, Kellogg and Stevens.

Consequently, the families here assigned may be significantly altered within the next several years. For the time being, family structure as delineated in the Jepson Online Interchange will be used. Therefore, the Boraginaceae family has recently been treated to include the Hydrophyllaceae family. Also many genus previously included in the Scrophulariaceae family are now taxonomically described as in the Orobanchaceae family.
