Opis

Excerpt from Journal of the Royal Horticultural Society, Vol. 11 Petals. - We may roughly classify the Saxifrages under three groups, according to the colour of the petals: pure white, as in hypnoides and granulata white dotted with small spots of red, as in umbrosa and stellaris; and bright red or bright purple or bright yellow, as in aizoides, Hirculus, and oppositifolia. I should like to ask whether this difference in the colour of the żower is at all correlated with its attractiveness to insects. According to the observations of Hermann Muller, some of the bright-coloured species, in their native homes amongst the mountains, are Visited by an extraordinary number and variety of insects. He gives a catalogue of 126 Species which he has observed to visit the bright yellow żowers of S. Aizoides. Eight of these are Coleoptera (beetles), 85 Diptera (żies), 20 Hymeno ptera (bees), and 13 Lepidoptera (butterżies and moths). To what extent are the żowers of the garden Saxifrages Visited by insects '2 What relation, if any, have the red dots on the white petals of several of the Species to insect fertilisation. The glandulosity of the calyx must interpose a barrier to small wing less insects creeping up into the żower from below.
