We studied the floral and pollination biology of Amomum maximum. Our observations suggest that flexistyly is present in this species, and stigmatic behavior is similar as reported for Alpinia species. Two phenotypes occur in a ratio of 1:1 in natural populations. No fruit set occurred in the unpollinated bagged plants. Significant differences in seed set(More)
Mature seeds of 109 species of Pedicularis representing 13 groups according to Tsoong’s infra-generic classification were investigated using light microscopy (LM) and scanning electron microscopy (SEM). The largest seeds occurred in P. superba (4.82 ± 0.32 mm × 2.18 ± 0.18 mm) and the smallest in P. crenata (0.95 ± 0.16 mm × 0.72 ± 0.08 mm). The individual(More)
Striking interspecific variations in floral traits of the large temperate genus Pedicularis have given rise to controversies concerning infra-generic classifications. To date, phylogenetic relationships within the genus have not been well resolved. The main goal of this study is to construct a backbone phylogeny of Pedicularis, with extensive sampling of(More)
