Pollinarial Morphology of Ten Species of Family Apocynaceae Found in Southern Shan State
- Pollinarial morphology of 10 species belonging to eight genera of Apocynaceae were studied. All the specimens were collected from Southern Shan State from July 2016 to September 2017. The flowering plants were collected, classified, identified and preserved. The pollen grains were found as tetrads and pollinia. Pollen tetrads were observed in two species Hemidesmus indicus (L.) R. Br. and Streptocaulon tomentosum Wight. and the eight species were pollinia. The small size of pollen tetrad was found in Hemidesmus indicus (L.) R. Br. and the large size of pollen tetrad was occurred in Streptocaulon tomentosum Wight. Pollinial morphology of 8 species was recorded with their size, shape, colour, orientation and translator attachment to the pollinia. The pollinia of each species were presented with photomicrographs.
