Stem anatomy From a morphological point of view the stem presents: in hemicryptophyte scapose spe- cies, lignified and prostrate at the base, briefly creeping, in H. perforatum and H. perfo- liatum respectively; lignified creeping with ascending branches in H. pubescens; prostrate then erect, ligneous in H. tetrapterum and H. triquetrifolium, in the latter strongly branching (PIGNATTI 1982).	cache/abc-681.pdf	txt/abc-681.txt
