Table 1 Coding of mating types for 30 Bulbophyllum clade C species included in this study, following the mating type classification of [48]. Species fixed for outcrossing were coded as state ‘0’, and dimorphic (outcrossing/selfing) species as state ‘1’ (‘any-instance’ coding; see text for details). For two species (B. spp. nov. ‘B’ and ‘D’) mating type was coded as missing (‘NA’)
