碩士 / 國立臺灣大學 / 植物學系 / 81 / This study is concerned with the 5 genera, 13 species of
tribe Millettieae in Taiwan, using light microscopy,
scanning electron microscopy, and transmission electron
microscopy to examine pollen morphology. It also uses
scanning electron microscopy to examine seed morphology. The
exine stratification is similar in the pollen of this
tribe. Its interstitium is in the form of columella. The
foot layer ranges from clear and connected to unconnected and
layered, but it is not divided by genus. Exine ornamentation
is clearly differentiated in each genera. However, there
is no way to distinguish between the exine ornamentation of
different genera. The types were distinguished by exine
ornamentation and exine stratification. The genera Derris,
Pongamia, and Wisteria are each represented by a single type.
The genus Millettia and genus Tephrosia are each represented by
three types. The pollen types of the tribe are
continuously changing. Palynological character is useless
in determining intergenus taxonomy; however, palynological
study can be used to identify the plants of the tribe as
complex in taxonomy. Using pollen types can clarify
intergenus taxonomy through comparison with morphology.
Palynological study and seed morphology support the
combination of the taxa of Tephrosia purpurea. In addition,
this study has determined two different kinds of exine
ornamentation in the pollen of Derris oblonga. It has also
determined that the pollen of Millettia pachycarpa and Pogamia
pinnata have different exine ornamentation at different
stages of development. Concerning the phenomenon of pollen
development, more research is necessary.
