The stigmas themselves are of a different shape, more flattened and not cylindrical. The pollen falls from the anthers abundantly on them, and germinates in the ordinary manner. The ovary which in lamarckiana and in all other new forms is wholly underneath the calyx-tube, is here only partially so. This tube is inserted at some distance under its summit.
A rose was interesting because it had a past. "Bosh," said the Realist, "I will tell you what a rose is; that is to say, I will give you a detailed account of the properties of Rosa setigera, not forgetting to mention the urn-shaped calyx-tube, the five imbricated lobes, or the open corolla of five obovate petals."
The most obvious characteristic marks are afforded by the flowers, which in O. muricata are not half so large as in biennis, though borne by a calyx-tube of the same length. In this respect the hybrid is like the biennis bearing the larger flowers. These may at times seem to deviate a little in the direction of the other parent, being somewhat smaller and of a slightly paler color.
