Mem. de l' Acad St. Petersburg 3/197 1809—10 (Published 1811) Kölreuter dissert. de pub. antherarum: (2d part, but contains conclusions) Pollen of air-coupling plants, such as chiefly Dioecious & Monoœcious globosum & excessively small - Commonest form is oblong, smallish & smooth

Pollen aculeatine almost passes to Compositæ & order of Malvaceæ - says it serves to attach it to insects, whose orifice is in fructifying Monodelphia & Syngenaria in ist maxima. [insertion:] (it is interesting there being provision in compositæ wh I thought would fructify themselves) (and this assistance is absolutely necessary in genus. Iris, in Viscum albus & in the Cucurbitaceous order). In X Athera Malva & Lavatera &c stigma is ready & open when pollen of own flower is past, but pollen is always brought by more recent flowers by insects - not without this assistance would impregnation ever take place as the pollen from the aculus adhere together like burs. (Do bees visit Malva more than other flowers - when one reflects how often they visit all flowers, it is no wonder every flower being impregnated)

p. 198 "an id aliquid in recessu habeat, quod hujuscemodi flores nunquam proprio suo pulvere, sed semper eo aliarum su speciei impregnentur, merito quaritur? Certe natura nil facit frustra."

I can answer this - put it at end of Chapter stating, that Koelreuter only asks his question with respect to Malvaceæ & say I believe I can answer it.

If self-fertilisation was natures intention, what can be the meaning of pistil [2 words illeg] to put out pollen, as in Comp. as in Lobelia [few words illeg]
