Abstract

Abstract

 Twenty-seven accessions from six (6) Cucumis L. taxa were observed to determine and elaborate differences when it comes to leaf venation patterns or leaf architecture characters. In this study, matured leaves from Cucumis species and subspecies namely: C. pustulatus Naudin ex Hook.f., C. dipsaceus Ehrenb. ex Spach, C. ficifolius A. Rich., C. melo ssp. melo, C. africanus L.f., and C. myriocarpus ssp. myriocarpus, were collected and subjected to leaf venation analysis. The leaf venation patterns of these Cucumis accessions were fully highlighted and illustrated in this study following the research published by Masungsong et al. (2023). Results showed that the Cucumis accessions exhibited similarities in apex shape (convex), base shape (lobate), base angle (wide obtuse), apex angle (odd lobed obtuse), laminar shape (orbiculate with distinct serrations at the margins), primary vein (actinodromous suprabasal), secondary vein (craspedodromous), quaternary vein (regular polygonal reticulate), and marginal ultimate venation (looped). Dissimilarities of leaf characters were observed in blade class, primary vein size, and secondary vein spacing. These results were congruent to the previously studied Cucumis species. Thus, the use of leaf architecture or leaf venation analysis is very valuable in describing and categorizing taxonomically complicated species like Cucumis.
