Excerpt from The Journal of the Horticultural Society of London, 1847, Vol. 2 It appears that if two stigma-bearing lobes of a triple or even tripartible style are cut Off, the whole germen may be fertilized by the one left. In such cases, therefore, the pollen tubes from one lobe must be able to penetrate all the cells of the germen. In cases such as I have seen, where both natural and hybrid seeds have been produced in one capsule, I cannot state whether the two sorts of pollen acted through the same or dif ferent lobes. I have in no instance succeeded in Obtaining any multiplicate cross by blending the pollen of two or more kinds intimately before their application. Mr. Knight thought he had given at the same time the curl of one cabbage and the red colour of another to a third variety. My invariable failure in such attempts induces me to think his recollection was inaccurate, 1f he meant that he had done so at one fructification. He might easily have Obtained the twofold features by two successive crosses, but I believe not in one generation by simultaneous application of different pollens: for I do not think that two grains even of the same pollen can get effectual access to the foramen of one and the same ovule. I now understand, nearly at least to my own satisfaction, in what manner the pollen of Rhododendron may in the fertilization of the ovules supersede the pollen of Azalea previously applied because I do not believe that they are always fertilized so soon as has been usually supposed. The stimulus may have been given to the germ or outer coat of the seed-vessel, and yet the fertilization may not have reached the ovule, and the operation which produces a living embryo may remain suspended till a change of weather and a moist atmosphere afford a supply of carbon, or whatever is needful thereto; and therefore that pollen which has perfect affinitytto the plant may develop itself effectually at a later period on a change in the state of the atmos phere; but, when the pollen has once reached and stimulated the foramen, further access will be assuredly denied. I have repeatedly observed in dry seasons the pollen of Rhododendron very parched and seemingly deficient, the stigmas dry, and the germens remain ing for weeks nearly stationary after flowering, as if no seed would be produced; but, upon a change of weather inducing moisture, universal fertility of the pods soon became apparent. I suspect that in such cases the fertilization has remained incom plete from want of the food necessary to the elongation of the tubes. If such views have any foundation in truth, it is possible that, in addition to mere water, a supply of the chemical ingre dients which are the food Of plants to the style may facilitate difficult impregnations. It is certainly desirable, where dry pollen is to be tried, to moisten the stigma to which it is about to be applied.
