The species, however, appear to differ among themselves in the relative positions of the stamens and Fig. 96.—Puhnonaria oj^cinalis. In this beautiful and interesting family, though we have not above twenty British species, we find, as Miiller has well pointed out, the widest differences in the conditions of fertilisation. Pulmonaria officinalis is dimorphous, and sterile—not only with its own pollen, but even in some cases with that of a different flower, unless it belongs to the different form. Echium vulgare has lost the power of self-fertilisation, but, so K 2.
