With the aim of inferring phylogenetic relationships among 86 species (including 45 species from Vietnam) mostly of the subfamily Convallarioideae (=Nolinoideae) (Asparagaceae sensu APG IV), we analyzed their chloroplast DNA sequences (rbcL and trnL-F) by both Bayesian inference (BI) and maximum likelihood (ML) methods. Our dataset included six of the seven tribes classified in this subfamily; Convallarieae, Dracaeneae, Liriopeae Nolineae, Polygonateae and Rusceae (Eriospermeae not examined). | ACADEMIA JOURNAL OF BIOLOGY 2023 45 4 93 109 DOI 2615-9023 18765 MOLECULAR PHYLOGENY OF CONVALLARIOIDEAE ASPARAGACEAE WITH EMPHASIS ON VIETNAMESE SPECIES Thi Mai Linh Le1 Ngoc Sam Ly2 3 Van The Pham4 Phuong Hanh Nguyen1 Duc Binh Tran1 Li-Na Dong5 Leonid V.

Our dataset included six of the seven tribes classified in this subfamily Convallarieae Dracaeneae Liriopeae Nolineae Polygonateae and Rusceae Eriospermeae not examined . Our study supported the sisterhood between Convallarioideae and Asparagoideae and the monophyly of all the tribes except Polygonateae. Within the Convallarioideae we examined Dracaena formed the basalmost clade. Theropogon did not positively nest in any of the tribes including Convallarieae in which it had often been classified. It was weakly defined as the second basalmost branch. Ruscus Rusceae nested in Polygonateae as the sister to Maianthemum .
