phylal

adj

1. (not-comparable)Relating to a taxonomic phylum.

   “Phylum Aschelminthes. Roundworms, rotifers, and gastrotrichs are grouped together for anatomical reasons as one phylum, although some authorities give each a phylal status.”

   “A technique that is often poorly used is the “phylum and characteristics” approach. In this approach, students must memorize spellings of phylal names and lists of characteristics.”

   “The classification of organisms presented here is a general summary, down to the phylal level, with some groups carried down to still lower levels, and is published at the request of members of the Society for a comprehensive general grouping for guidance in further study on the basis of a selected bibliography.”
