Note 50 — Class—CRUSTACEA. Sub-Class—CIRRIPEDIA. (continued 4)

Certain plants offer a closer, though not perfect, analogy. Thus, in the florets of some compositous flowers, the pistil, besides its proper female functional end, serves to brush the pollen off the anthers; while, in the florets of some other compositæ (see the account of Silphium in ‘Ch. K. Sprengel Das entdeckte Geheimniss der Natur’), the pistil is functionless for its proper end, the flower being exclusively male, but its style is developed, and still serves as a brush. So in the male Ibla, part of the ovaria, in a modified condition, is still present, and serves as a cementing apparatus.
