Limnanthemum Indicum 2. forms described by Thwaites ─ spec. allied to [illeg] bean dry & in spirit─
I have examined only 2 flowers in Spirits
Long-styled with style about twice as long as in short-styled; in long-styled to foliaceous stigma is larger, not so much folded together with stigmatic papillæ rather more protuberant on edges.─ In the long-styled filaments of stamens about half as long as in short-styled; & anther itself smaller:
I fancy pollen in short-styled short anther ⸮ / in long-styled is rather larger ─ see Thwaites note about same shape & ovule equally numerous in both forms.─
Examine pollen out of dry flowers in cupboard & again in spirit. Rexamine all above statements.─

long-styled ─ long style very much longer & thinner than in short-styled
Stigma seems more foliaceous in long-styled
pollen of short-styled 7-8
─ of long-styled ab 5-6
about long 6 short 7
long-styled is to short-styled in length as 14 to 5 breadth 3 3 to 5
Say only grains certainly larger short-styled
Length 280 long-styled ─ 14/5 breadth = 30/50
2nd [illeg] 210-70 ─ 3/1
In Menyanthes short-styled seem to be larger anther

If a thick needle be injected into the mouth of the nectary (fig. A) & then withdrawn, the viscid disc will surely be withdrawn, bearing with it the elegant fan of radiating pollen-masses. These undergo no change in position. but if the needle be now inserted into the nectary of another flower (fig. C.) the ends of the pollen-masses necessarily strike necessarily hit the upper slope surface & the laterally sloping sides of the rostellum, & glancing off
