Maotianshan Shales fossil record. Phylum Porifera (sponges; 15 species) and Priapulida (16 species) are also well represented. Other phyla represented are Brachiopoda, Chaetognatha, Cnidaria, Ctenophora, Echinodermata, Hyolitha, Nematomorpha, Phoronida, and Chordata. Possible molluscs include "Wiwaxia" and "Nectocaris". About one in eight animals are problematic forms of uncertain affinity, some of which may have been evolutionary experiments that survived for only a brief period as benthic environments rapidly changed in the Cambrian. Chengjiang is the richest source of the lobopodia, a group including many early panarthropods, with six genera represented: "Luolishania", "Paucipodia", "Cardiodictyon"," Hallucigenia" (also known from the Burgess Shale), "Microdictyon", and "Onychodictyon".
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.
