Stamen length including anther
connivent, connivent, the stamens of a flower vary in length
length stamens exserted beyond distal end of corolla (applicable if corolla is tubular or campanulate) in the protologue we wrote "exertos" but when I compare the photos of 643 & 819 (grandibaccata) with those of 642 and 818 (guiermo-guerrae) I don't see a clear difference most photos we took in the field in Peru show stamens included, as described in the protologue, but one of my photos of Mione et al 713 shows stamens exserted a few mm

insertion of filament into anther inserting on the lower ventral face of anther inserting on the lower ventral face of anther
anthers of a flower open simultaneously? photos taken in Peru provide no evidence that anther dehiscence is Not simultaneous, but we may have merely photographed the flowers at a time of day after all anthers dehiseced photos taken in Peru provide no evidence that anther dehiscence is Not simultaneous, but we may have merely photographed the flowers at a time of day after all anthers dehiseced
