Morfological aspects of the fruit, seed and post-seminal development of faveira (Clitoria fairchildiana R. A. Howard - Fabaceae)

The present work aimed to describe the morphology of the fruits, seeds and the post-seminal development of faveira (Clitoria fairchildiana R. A. Howard. - Fabaceae). The fruits and the seeds were characterized as its form and dimensions. Periodically, representative units of each germination phase had been removed for the morphological descriptions. The fruits are dehiscent legume of brown coloration. The seeds are unalbuminous, of flattened orbicular form, with a chestnut-green tegument. The hilum is elliptical, homochromus and of small size in relation to the seed. The cotyledons are free, of green coloration, plan-flattened, bulks and the embryo is invaginated. The beginning of the post-seminal development is marked by the disruption of the tegument and emission of the primary root, glabrous and cylindrical of yellow-green coloration. Later, the development of the secondary roots is observed, lightly white, filiforms and shortness. After that, the growth of hipocotyl provides the emergency of the cotyledons and plumule. The epicotyl elongates and often is observed eophylum expansion, which are simple, opposite, with simple and dispersed tricomes, short petioles, with stipules in the base. Often the development of the eophylum, it occurs the formation of the second pair of leaves, alternating, trifoliolate, with stipels in the base of the footstalks.
