Confused about plant phyla
Phyta means plant... The different 'phytae' mark different levels in the taxonomy...

Example: 

Streptophyta from the Greek strepto, for twisted, i.e., the morphology of the sperm of some members and phyta (plant), a group including land plants and some algae

Embryophyta - land plants

Tracheophyta - vascular plants (from Ancient Greek τραχεῖα (trakheîa, “windpipe”) +‎ -ophyta) 

To answer your question... Phyta is a part of many plant taxonomy levels... It is not one type of plant but it marks the membership of a group to the kingdom of plants.
