| description | Cordia trichotoma, (Vell.) Johns, “Peteriby”, is a South American Borraginaceae, with feasible commercial application. The first part of this piece of research, a previous work, dealt with the study of the morphology and dimensions of the cell elements and their variation with age. In this second part, the study was focused on individual fiber morphology, all fibers as a statistical population as well as the relationship between fiber parameters. We were not able to identify the existence of two different statistical fiber populations, as previous works have claimed. This was made evident by the lack of more than one peak or any remarkable kurtosis in the qualitative frequency distribution analysis. The cell wall thickness increases are correlated positively with fiber width but not enough so as to keep the fiber flexibility coefficient constant. Accordingly, the wider the fiber, the higher the fiber flexibility coefficient. The fiber flexibility coefficient decreases in accordance with longer fibers. The fiber width is independent of fiber length. |

En la primera parte del trabajo se analizó la morfología, dimensiones y variación con la edad de los elementos celulares. En esta segunda parte se estudió la morfología individual de las fibras, el conjunto de fibras como una población estadística, y la relación de los parámetros fibrosos entre sí. De acuerdo con trabajos morfológicos anteriores de latifoliadas naturales, se trató de confirmar la existencia de dos poblaciones estadísticas de fibras, hecho que no se observó en este caso, no pudiendo emostrarse más de un máximo o una curtosis significativa en las distribuciones de frecuencia por atributos. El espesor de pared aumenta a medida que aumenta el ancho de fibra pero no en forma suficiente para mantener el coeficiente de flexibilidad constante. De tal manera, las ibras más anchas poseen mayores coeficientes de flexibilidad. A medida que aumenta la longitud de fibra, el coeficiente de flexibilidad disminuye.
