Eritrichieae tribe phylogeny (Boraginaceae) based on morphological characters in Iran

Eritrichieae tribe from Boraginaceae sect consists of 4 subtribes, 6 genera and 28 species in Iran. Thirty-three morphological characters in 28 species of Eritrichieae tribe and 6 species of its related species (4 species of Cynoglosseae tribe and 2 species of Myosotideae tribe) were studied. The main aim of this research was to investigate the phylogeny renovation of Eritrichieae tribe and its subtribes. The studies were performed on samples available from Tehran University Herbarium and Botanical Research Center of Mashhad University using the Maximum Parsimony method as implemented in PAUP* software. Trichodesma africanum from Cynoglosseae tribe was selected as the out-group. Results of analyses showed that Myosotideae is monophyletic but Cynoglosseae and Eritrichieae forming a clade together with their respective genera intermixed and none of them is monophyletic. Among of subtribes of Eritrichieae, Rocheliinae including only Rochelia (fruits with 2 nutlets), and Heterocaryinae including only Heterocaryum (with 4 nutlets, usually unequal, compressed, winged margin and appendages glochidiate) are monophyletic. So, situation of these subtribes are conserved. Within Eritrichiinae subtribe, the Lappula represented herein by 10 species was paraphyletic, and the Lepechiniella with 3 sampled species here was also not monophyletic. The Asperuginae subtribe (represented by Asperugo procumbens, solely), with calyx divided into linear-lanceolate lobes, accrescent and saucer-like in the fruiting stage, is here resurrected as the Asperugeae tribe.
