The paper reports a morphological study of fruits and seeds of Ruscus hypoglossum L., a species interesting as an ornamental plant. Initially, the length, width and weight of fruits as well as seeds were measured in 14 natural populations growing in Croatia. The length/width ratios of fruits and seeds were calculated, as well as the fruit/seed ratios of length, width and weight. Interannual differences in the analyzed traits over three years were compared in two populations. The most promising populations for further selection for ornamental use were the Bilogora population with the largest fruits (length 12.30 mm, width 11.56 mm, weight 0.75 g) and the Strahinščica population with the roundest fruits (length/width 1.04). The average number of seeds per fruit for the populations was 1.40. Variability between the three years was minor for fruit traits but significant for seed traits.

Genetic relatedness among basil accessions including six species of Ocimum (O. basilicum L., O. americanum L., O. x citriodorum L., O. minimum L., O. gratissiumum L., O. tenuiflorum L.) and six botanical varieties or cultivars of O. basilicum L. [var. basilicum L. cv. Genovese, var. basilicum L. cv. Sweet Basil, var. difforme Benth., var. purpurascens Benth., cv. Dark Opal, and var. thyrsiflorum (L.) Benth.] were analyzed by random amplified polymorphic DNA (RAPD) markers. Five primers were used for amplification. They yielded a total of 102 easily scorable polymorphic markers. Jaccard indices were calculated and phylogenetic relationships were determined by neighbor-joining cluster analysis. Different Ocimum species were clearly divided into separate clusters with the exception of O. minimum accessions, which clustered together with O. basilicum accessions. In addition to morphological, chemical and crossability data, RAPD analysis can be a useful tool for resolving existing problems in identification and classification of basils.
