Dec 30 1868 Viola-nana from India from seed from John Scott — has flowered all summer & is now flowering, but very imperfect flowers & not one perfect flower.─ & seeded & seeds grown profusely.─
These consist of 5 sepals produced backwards round base of peduncle.─; sometimes reduced to 4 or 3 sepals!
5 exclusively minute scales representing of with purplish tips rudimentary & very irregular petals, of unequal length & one divided.─ I am not sure whether some of these were rudimentary stamen.─
2 (certainly only 2) stamens, with 2 distinct & somewhat distinct, very distinct spherical, prominent, anther-cells seated at base of large lancet-shaped membrane expansion. ─ most contain very little pollen. Anther became orange in older flowers [sketch] hollow beneath.
(Ovarium terminates in short flattened tube, a little bent over & close to anther ─ Thin tube seen absolutely open; in older flowers & withered, expand into slight circular membrane, which form a sort of stigma.─ The 2 perfect stamens face bent pistil, & ∴ no doubt are 2 upper stamens.─ There are rudiments unequally developed ↘

of 3 other anthers; generally very minute;─ one is often larger & in one specimen included single anther cell on one side with pollen.─ i think not above 20 or 25 grains of pollen in each cell ─ very delicate & transparent, emit tube whilst in cells.─
[in margin:] published as in edition
(N.B. Frank & I have now examined about 25 30 fl. out of them 5 had only 3 sepals, but in most case between them a partially coloured filamentary rudiment (much larger than ordinary rudiments) was developed, which from arising more inwards apparently represented one of a petals; in these flowers the minute rudiments were fewer in number ─ The reduced no' of sepals is not result of confluence of 2 sepals.─
