The species Retrophyllum rospigliosii (Pilg.) C. N. Page (Female Romerillo) and Prumnopitys harmsiana (Pilg.) de Laub. (Male Romerillo) are conifers native to Peru and form an important part of the cloud forests of the Department of Cajamarca. Their woods are in demand in the local market for carpentry works, due to their physical-mechanical properties and good finish; however, information on the microscopic structure is scarce. The aim of this work was to characterize and determine the anatomical differences in the wood of the two species and thus expand the knowledge of their structures. Samples were obtained by non-destructive method, prepared and studied by microtomy and maceration; whose description was made using the IAWA standard. The main qualitative characteristic that allows differentiating them is the presence of diffuse parenchyma in Retrophyllum rospigliosii and absent in Pr...

Las especies Retrophyllum rospigliosii (Pilg.) C. N. Page (Romerillo hembra) y Prumnopitys harmsiana (Pilg.) de Laub. (Romerillo macho) son coníferas nativas del Perú y forman parte importante de los bosques nublados del Departamento de Cajamarca. Sus maderas son solicitadas en el mercado local para obras de carpintería, debido a las propiedades físico mecánicas y buen acabado; sin embargo, información sobre la estructura microscópica es escasa. El presente trabajo tuvo como objetivo caracterizar y determinar las diferencias anatómicas de la madera de las dos especies y así ampliar el conocimiento de sus estructuras. Se obtuvieron muestras por método no destructivo, preparadas y estudiadas mediante la microtomía y maceración; cuya descripción se realizó utilizando la norma del IAWA. La principal característica cualitativa que permite diferenciarlas es la presencia de paré...
