Jovan Hadži theories of animal evolution. He devised a system of classification in which he divided the animal kingdom into six phyla: Protozoa, Parazoa, "Ameria" (animals with no segments), "Oligomeria" (animals with few segments), "Polymeria" (animals with many segments) and Chordata. His choice of characters important for classification was generally discredited by his contemporaries, and the system was never accepted by zoologists. However, due to its simplicity, the system was widely used in science education in former Yugoslavia. His other major theory was that of the origin of metazoa - he developed an existing hypothesis stating that the first multicellular animals resembling
Phyla nodiflora look, which is why the plant is sometimes called matchweed. It is similar to the related species Phyla lanceolata, but differs in having much shorter leaves that are often blunt and much more rounded. Both species are common as weeds and in the ornamental environment. Common names in India include bukkan (Hindi), ratolia, vakkan (Marathi), podutalai (Tamil), vasir, and vasuka (Sanskrit). It is used medicinally to treat suppuration, common colds, and lithiasis. "Lippia canescens" Kunth, "Lippia incasiomalo" (Small) Tildsoan, "Lippia lickiflora" (L.) Michx., "Lippia nodiflora" var.
