Comparative analysis of the leaf architectural characters of Saurauia bontocensis Merr. and Saurauia polysperma (Blanco) Merr. with the application of Digital Image Analysis Software

Abstract. Daipan BPO, Buot IE Jr., HMO. 2022. Comparative analysis of the leaf architectural characters Saurauia bontocensis Merr. and polysperma (Blanco) with application Digital Image Analysis Software. Biodiversitas 23: 3869-3875. Major confusion still exists among several authors concerning taxonomy dagwey plant. This species is economically significant to Ikalahan tribe Luzon, Philippines. Several papers claimed that plant bontocensis, while others stated it subglabra. Many botanical websites S. subglabra synonymous polysperma, another article distinguished from polysperma. Thus, help resolve taxonomic ambiguities, this paper performed a comparative aid digital image software cluster analysis. Results revealed blade alone, delineate two species, particularly, in terms laminar size, shape, symmetry, L:W ratio, base apex angle, shape. Additionally, venation specifically, on 2º 5º vein categories, 3º course, angle 1º, areolation, freely ending ultimate veins, marginal venation, rank. Generally, have larger, longer, wider leaves compared The architecture produced very promising result differentiating could be used address some these species. study indicated are distinct Moreover, use was helpful computations various characters, particularly herbarium exsiccate absence actual samples.
