Gl. Vonposer et al., IRIDOID GLUCOSIDES SUBSTITUTION PATTERNS IN VERBENACEAE AND THEIR TAXONOMIC IMPLICATION, Plant systematics and evolution, 205(3-4), 1997, pp. 265-287
The familiar limits of Verbenaceae are controversial, ranging from a s
ensu late arrangement of seven subfamilies until a sharply defined sen
su stricto group consisting of only some genera from subfam. Verbenoid
eae. Iridoid contents of genera belonging to Verbenaceae s. 1. were ex
amined through a cladistic analysis, using outgroup analysis to evalua
te character polarity within the ingroup. The cladogram obtained shows
the distribution of the species according to their iridoid content.
