PO:0030127 has errors. The current definition is "An inflorescence (PO:0009049) which at anthesis is composed of an indeterminate first order inflorescence axis (PO:0025104) and dichasial second order inflorescences (PO:0025240) with pedicellate (PATO:0001438) flowers (PO:0009046) and determinate higher order inflorescence axes"
The problems are (1) the "second order inflorescences" (that is a terrible term, but that is for another post) can be monocasial as well as dichasial. Monocot thyrses have monochasial second order inforescences. (2) the flowers do not have to be pedicellate. They often are, but they do not have to be for an inflorescence to be a thryse. (3) Some of the higher order axes are determinate (the monochasial or dichasial cymes), but other higher order axes are indeterminate. This is easier shown with a diagram like this one: https://commons.wikimedia.org/wiki/File:Heterokladische_Thyrse_(inflorescence).PNG. You see that the second order branches in this diagram are indeterminate.
