The flowei-s of the Cress, Mustard, Cabbage, etc., have four petals, arranged two and two opposite, somewhat like a cross, and they are said to be cruciform (Lat. crua:, cross; Fig. 108). 58. A conspicuous irregularity in the flower is caused by the production of appendages of various kinds. One petal in the Violet is f'^/Zf// '^'y^^\ prolonged so as to form a spur; this organ is tubular, and generally con- tains Nectar, or los sweet substance secreted by the flower. One species of Dicentra is two-spurred. All the petals of Fig. 106. A head of flowers of Heliopsis: i», involucre; ^ disk-flowers ; Itff, ray-flowers; ch, chaff; acli, achemia. Fig. 107.
