Oxalis acetosella April 17 1862

5 Pistils with rough stigmas on level with 5 longer stamens — The 5 shorter stamens face the petals, & are a little more than 1/2 length of longer ones. Anther open nearly at same time; pollen coherent —

Anthers extreme, but then of longer ones so near pistil, that self fertilisation almost unavailable; especially as flower drops down????

I could see no nectar. Base of petal narrowed so passage to calyx — on each side of narrowed base, possibly a nectary.— I [forget] thinks these are salt-drusen, but I am not sure that has been seen nectar.—

Ap. 18 drop of nectar on narrow footstalk of each petal beneath & between the coherent fleshy projection or petals

Hooker believes long & short stamens are ordinal [illeg] character.—

Pollen same size in long & short anthers; & in both supposed forms viz 11 to 12/7000 & when much distended by water 14-15/7000.

Stigmas similar in both forms, perhaps papillæ longer in long-styled.—

Ap. 19 Examined 18 flowers — 14 with ste pistils projecting, 4 with equal length to longer stamens — apparently not due to age. ♀ flowers ­—

Ap. 21 Four more plants all long-styled. (Vehemently doubts about dimorphism.)

April 24th Prof. Oliver sent me 38 flowers, of which 24 long-styled & 14 short-styled. There is some variability of length of pistil; still I think there is something more in this difference.

Ap. 25. George brought me 17 flowers from so many plants from near Hanggrove — all these long-styled, several had pistils projecting fully as much beyond long-stamen, as these latter project beyond short-stamens—

à Important to note this variability in grains of dimorphic forms — 24 14 short

[2v]

Ap. 27 — 62. I examined 17 more flowers from as part of Big wood, all these long-styled, & some very long-styled; & 4 short-styled but in various degree — Evidently length of style extremely variable.—

10 flowers from near Southampton all very long-styled.— Ap. 29th—

Oxalis Bowii has pistil far below lower stamen

O. floribunda (Mr Turnbull) do do above upper stamen

may 3d. fertilised 2 flowers of O. Bowii (white worsted) with pollen of O. floribunda: one of O. Bowii with own pollen. black worsted: Flower closed, as gloomy day.

May 5 & 11th fertilised 6 flowers of O. Bowii (marked with white Bobbin) with pollen of long-stamen, but some of short may have got on.— Also 6 flowers (marked black worsted) with pollen of short & adjoining stamen & think I succeeded in none of long, which I reared, getting on.—

/None of them set pods/
