[C17]

Sept 15th 1841. Zoolog Gardens in a great tall scarlet Lobelia, same and-gam Dichogamous structure as observed at Maer.— does Pollen drop from the upper flowers on the lower? In Siphocamphylus two coloured species next genus to Lobelia — same structure, though the anthers were far from cleanly brushed out (as Lindley terms it by the cup-like fringe)

In Lobelia begonifolia & some small blue species same structure.— Here pollen cannot drop from flower to flower as they are not on upright stem, but I saw many Hive Bees visiting them, wh. do not insert proboscis at Mouth of flower [sketch] but at (a) where there is a natural slit, within which the separated filaments allow of passage — These bees, however, generally brushed over anthers & pistils because they generally alighted on the fringed lower lip & so crawled along upper side of flower — At Down this has not been the case, for the Bees went to mouth of Flower.—

{Tropæolum pentafolia has large spur nectary full of honey.— stamens bend slightly up to gangway — it is and-gun — dichogam—for pollen is shed, when pistil is short & the three segments of stigma quite close ─ however when pistil is grown much longer & these clefts open, yet there are some pollen & often much on anthers.— (One the Nasturtium Tribe)
