Developmental sequences of reproductive units in Trithuria submersa

Developmental stage	Stamen	Carpel
1	Filament not elongated, anther not above carpels	Stigmatic hairs short (mean of longest hair = 253 ± 58 µm; n = 7)
2	Filament partially elongated, anther beginning to emerge above carpel body, but not above stigmatic hairs	At least one stigmatic hair per carpel has begun elongating
3	Filament fully elongated, anther above carpel tops and many of the stigmatic hairs. Anther not dehiscent	Typically two stigmatic hairs per carpel have elongated (mean = 463 ± 172 µm; n = 15)
4	Filament fully elongated as in stage 3. Anther dehiscent	Stigmatic hairs as in stage 3, some hairs bent with collapsed cells
5	Anther abscised	Stigmatic hair length as in stage 3 (mean = 480 ± 239 µm; n = 10)
