Observe, however, tiiat the veining of the leaf (Fig. 83) is different, that of Calla being straight, Hke the Dog's-tooth Violet. There is also a difference in the flowers. Tliose of Indian-Tur- nip were found to be dioecious, but the spadix, in the present case, bears both stamens and pistils, and the lower flowers, if not all, are perfect; some- times the upper ones consist of stamens only. Fig. 84 shows one of the perfect flowers much eulirged. The stamens, it will be observed, have two-celled anthers, opening lengthwise. MARSH Fig, onoAN. NO. COHESION. ADHESION. Poriantli. Wanting.

One of them projects forward in front of the flower, forming the Up, and bears under- neath it a long hollow simr, which, like the spurs of Columbine, is honey-bearing. The remaining five con- verge together forming a kind of arch over the centre of the flower. Each flower springs from the axil of a Is ii,|i.
