Flower and Flower Buds Note: a) the base of the urceolate corolla is filled with red-orange nectar visible through the wall of the corolla! b) corolla has both 5 lobes and 5 lobules alternating with each other c) stigma is darker green than the style, and is exserted beyond the dehisced anthers The flower bud on the right shows the corolla emerging from the calyx. The flower bud in the center has a closed calyx, and so is a younger bud.   (Photo by T. Mione in Connecticut, accession Leiva 138 = Mione 535)

Flower Development At Anthesis Note how distal end of corolla is not revolute when flower begins to open (left), but becomes revolute (right). Only the flower on the right has dehisced anthers. Units along top of photo are mm. (Photo by T. Mione, flowers on glass with glass elevated above red canvas to prevent shadow, in laboratory of Gregory J. Anderson).

Leiva, A. Sagástegui A. and M. O. Dillon).   Chromosome number n = 12 (Mione unpublished, meiosis of anthers from plants grown from seeds of Leiva 138).   Local name. Uses.
