Two phases were used. On the first phase, the filed phase, the external characteristics of the flower were analyzed using the established methodology of collection, conservation and transport of flowers. In the laboratory phase, the internal characteristics of the flower were determined, which was based on the guide "The flower, inflorescence and fruit", was by Biologist. Richard Javier Huaranca Acostupa (2010). In the species under study, it was determined that the flowering stage of Acnistus arborescens L, begins in the second week of the month of February and concludes the third week of the month of April. And this presents an inflorescence of the simple umbel type, with heterooclamid. The calyx is gamosepalous with 5 sepals. The stamen consists of five anthers and the gynoecium has a superior, bicarpel, bilocular and poly-ovular. In the case of Erythrina edulis Triana ex Micheli, the flowering stage starts from the fourth week of February and ends the fourth week of April. With a cluster inflorescence, with heteroclamid flowers with a ligulate corolla, hermaphrodites. Gamosepalous calyx with three sepals. The stamen consists of four stamens with greater length and four stamens of shorter length and the gynoecium has a superior, unicarpel, unilocular and poly-ovular |
