[B115]
Oxalis (Biophytum) sensitiva Perfect flowers.
Length of stigma lobes:
Short-styled is to mid styled long styled as:
100 164 26 141 61 100
The stigma of short-styled is decidedly the least papillose & I fancy that the midstyled stigma is more papillose than the long-styled one; but there is not much difference here
The style of the long-styled has much many more [glandular] & simple hairs on it than the mid styled; & the short-styled style has none at all.
Pollen grains, longest diameter
From long anthers of short style = 100
From mid anthers of short style = 91
From short anthers of mid style = 84
No other difference in appearance of pollen grain
