Abstract

In order to generate useful information to know the morphological variability and conserve and increase the spread of Cinchona officinalis L. (Rubiaceae) in its natural habitat, the characterization of the vegetative and reproductive organs of the species was carried out, in the sectors of Selva Alegre and Uritusinga, from Loja province (Ecuador). Qualitative-quantitative botanical descriptors were used for characterization. The trees of C. officinalis presented heights between 3 and 9 m, with opposite and decussate leaves, oval in shape, entire, penninervia, yellowish green, 7.3 to 16.9 cm long, with a 1.2 to 3.7 cm long petiole. In the quantitative variables such as width and leaf area, dissimilarity of values was evidenced between the two sites, with Selva Alegre presenting the highest value in the width of the base of the leaf blade of 4.33 cm. The flowers from the Selva Alegre site presented the highest values in the corolla area of 0.5 to 0.84 cm2, with a length of the stamens of 0.6 to 1.5 cm. On the other hand, the Uritusinga site reached the highest value in the length of the style of 0.8 - 1.6 cm, and the length of the flowers was 1.3 to 1.6 cm. The fruits presented an oblong or elliptical shape, dark red in color, with a length of 1.94 - 2.48 cm; the highest number of seeds per fruit was evidenced in the Uritusinga site, with the presence of 39 seeds/fruit with a seed length of 4.3 to 5.8 mm.
