Cormus
BODY OF A PLANT DIFFERENTIATED INTO ROOTS, STEM, AND LEAVES, AS OPPOSED TO AN UNDIFFERENTIATED THALLUS
Cormus (: cormi) (from ancient Greek: κορμός, kormόs, 'stem') is the appearance of a plant that belong to Cormophyte (Pteridophyte and Spermatophyte). In cormus, the vegetative apparatus is no longer a Thallus, such as Algae, that can't be distinctly differentiated.
