“…The investigation of D. lotus under introduction conditions shows evident polymorphism, which affects (nearly) all morphological features of this species (Grygorieva et al, 2009a(Grygorieva et al, , 2009b. We can find the varieties of all features which fluctuate in highly visible limits.…”

“…To test the hypothesis of the high variability of successfully colonizing species, it is necessary to estimate the variability of their phenetic and genetic traits. We have previously described the degree of the variability of Diospyros lotus fruits (Grygorieva et al, 2009c). In this study, we estimate the variability of the morphometric parameters of the male and female flowers of this species in the introduction population of Slovakia.…”

The morphological variability of the male and female flowers of 23 date plum (Diospyros lotus L.) genotypes found together at date plum collection in Arboretum Mlynany (Slovak Republic) was investigated. The collection consists of seed-propagated genotypes, which were established in 1970 with introduced seeds from different countries. Results showed that male and female flowers of D. lotus genotypes differed from each other in terms of shape and size. According to the morphological analysis, several features were found variable both within and between different plants. Moreover, significant differences in the colour of their corolla were detected. Female and male flowers of D. lotus genotypes were grouped according to the absolute parameters of flowers, and five (male flowers) and three (female flowers) clusters were identified. The degree of affinity between species was assessed using values of Euclidean distance. Using the principal component analysis, female and male flowers were separated into groups with similar morphological parameters. Our investigation has extended the understanding of the morphological features of D. lotus flowers as compared to the previously published data, which were limited only to a short description.

“…A morphometric study of flowers and fruits of D. lotus (Grygorieva et al 2009) showed that the average diameter of the calyx in D. lotus is 22 mm while the average calyx lobe is 9.5 mm long. Similar calyx types occur both in Eurasian and New World species (e.g.…”

Diospyros is a large genus of woody flowering plants with a predominantly subtropical and tropical modern distribution. Fossils attributed to Diospyros are mainly leaf impressions from Cretaceous and Cenozoic strata across the Northern Hemisphere. However, it is difficult to assign such fossils to Diospyros because genus-diagnostic leaf characteristics remain to be identified. Unequivocal fossil records of Diospyros are few, including staminate flowers with in situ pollen from the late Eocene of South Australia and dispersed pollen from Cenozoic strata in the Northern Hemisphere. Here, we investigated dispersed pollen and calyx remains from Miocene deposits of Denmark using a combined scanning electron/light microscopy approach. Tricolporate, relatively large pollen with lalongate pori and long bow-shaped colpi and a distinctive micro/nanorugulate exine ornamentation together with persistent 4-lobed flower calyces allow unambiguous identification of the genus. Based on the large size of the calyx, we describe a new fossil-species of Diospyros. Further, a review of the fossil pollen record of Diospyros shows that, in addition to the Australian record, the genus was present in South China, western North America and Europe during the Eocene and in East and South Africa and Central Asia during the Oligo-Miocene. Although still scanty, the pollen record can contribute vital information for timecalibrated molecular phylogenies to resolve conflicting biogeographic inferences. A thorough description of the historical biogeography of Diospyros is still in its infancy. While we initiate such a study here, development of a comprehensive picture will require further studies of dispersed pollen grains with high taxonomic resolution.
