Schutzmittel der Pollens A. Kerner 1873. ─ [1873 is a later annotation; all the notes refer to the 1876 pamphlet.]

p. 4 wind flower cannot be close to ground

p 10 x importance of protection of pollen against wind & Rain

p. 22 (Q) closing of corolla to protect anther from Rain (bears on my view of Mimosa) & Drosera (Cop)

p. 28 Ray florets do ─ vy good

[Cited in Forms of flowers,p. 6.]

27 New Holland plant which open only on one flower on plants ─ think the common cross between 2 individuals

25 dark-coloured night flowers attract by odour alone.

31 Bending of flower peduncles & stamens to protect anther very good─ (see to this when I quote)

34. mechanical excitement causing movement of flower-peduncle ─ very important for Tendril paper (Cop)

So drops of Rain, Mimosa & Drosera

38. Reflection of tips of petals in Hanging flowers aids insects

53. successive opening of anthers & umbra in some flower & the [illeg] of flowers bears on injury of many from Rain.

55 difference of size of corolla in Dimorphic plants depends on greater length of stamen in the short-styled & consequence greater size if corolla in do Dimorphism

56 so in dioicous plants & Thymus-like cases.─ Copied

[Cited on Forms of flowers, p. 309, n: "It does not appear to me that Kerner's view ('Die Schutzmittel des Pollens,' 1873, p. 56) can be accepted in the present cases, namely that the larger corolla in the hermaphrodites and males serves to protect their pollen from rain. In the genus Thymus, for instance, the aborted anthers of the female are much better protected than the perfect ones of the hermaphrodite."]

[2]

p. 59 on relation of corolla to uterus of [illeg] for protection of pollen.

─ speaks constantly of coherent [illeg], in contradiction of incoherent (use other terms) or wind pollen

61. believes it found the external conditions do not directly cause favourable variation

62 wind-flowers best adapted for growing close together in company.─ sp. which grow isolated must have coherent entomophilous flowers

(such cases as Reseda & Escholtzia good illustrations of what I call incidental changes.)

64. Enumerate vy close spec. which are distinguished chiefly by different periods of flowering
