. Handbook of flower pollination : based upon Hermann Mu?ller's work 'The fertilisation of flowers by insects' . Fertilization of plants. 126 INTRODUCTION But in North Ireland, where Sphinx convolvuli is relatively abundant, Convolvulus sepium (according to T. H. Corry) is even commoner than C. arvensis. There are transitional forms connecting the two groups of Lepidopterid Flowers. Hermann Miiller (Kosmos, iii, 1878, pp. 420-4) regards the following as such:—Daphne striata, Anacamptis pyramidalis, Gymna- denia conopea and odoratissima, Crocus vernus, and Lilium Martagon. The two first-named species represent all stages between Butterfly Flowers and Moth Flowers, for Hermann Miiller often observed that in the same alpine stations all colour gradations between rose red and white grew side by side. Butterflies and moths alike were observed as visitors and pollinators of both species. Crocus vernus and Gymnadenia odoratissima do not fluctuate in this undecided way between Butterfly Flowers and Moth Flowers, but incline distinctly to the latter group, as their colour only varies from white to pale rose. The circle of guests, in conformity with this coloration, consists chiefly of moths. While the four species just named show themselves to be transitional forms between Butterfly Flowers and Moth Flowers by displaying variable coloration, Ana- camptis pyramidalis and Lilium Martagon do this in a different way. They possess vivid colours and thus attract butterflies, but they also open in the evening and then emit a powerful and pleasing odour, by which moths (especially nocturnal Hawk-moths) are enticed..
