Fig. 1From: Primotrapa gen. nov., an extinct transitional genus bridging the evolutionary gap between Lythraceae and Trapoideae, from the early Miocene of North ChinaExtant Sonneratia and Trapa and the phylogenetic relationships of Lythraceae s.l. a Sonneratia apetala Buch.-Ham. from Qi’ao-Dan’gan Island Mangrove Nature Reserve, Zhuhai, Guangdong Province, China. b Trapa natans L. from Xuanwu Lake, Nanjing, Jiangsu Province, China. c, d A leaf of T. natans L. and an enlargement (d) showing the characteristic double apices of the teeth on the leaf margin (red arrows). e A series of fruits of T. natans showing different developmental stages. f A sepal of T. natans with the cortex removed, showing dital, recurved barbs. g The position of the ovary in Lythraceae s.l. mapped on the Bayesian 50% majority-rule consensus of 4000 trees from the combined molecular data of four gene regions [10, 11]Back to article page
