“…Yet, there is a large amount of recent literature exploring morphological variations in plants as dependent on environmental factors. For instance, sea daffodils (Pancratium maritimum L.) vary their morphological features according to the bioclimatic variables to which they are exposed, including precipitation, average annual temperatures, and strong irradiance [33]. Subtler climate effects were observed in Pinus flexilis E.James, where there was no macroscopic variation in morphology on a large elevation gradient (1600-3300 m), yet stomatal density was inversely correlated with elevation [34].…”

Globularia is a genus of small evergreen and perennial shrubs that are widespread in Europe. Globularia section Empetron includes a group of three species, G. cordifolia, G. meridionalis, and G. neapolitana, that have been taxonomically disputed for more than 150 years. Many morphological features have been proposed to discriminate these species. Nevertheless, evidence from both past and recent literature suggest that these differences among species are not consistent. In order to shed new light in this long-disputed group, we investigated 10 populations of the G. cordifolia species complex with both classical and geometric morphometrics and used environmental predictors in multivariate regression to explain patterns of variation. Our results showed that bract area and calyx teeth length are correlated with solar radiation and annual precipitation, whereas leaf dry mass per unit area can be explained by temperature seasonality. Leaf shape can be explained by temperature seasonality as well, although with a lower amount of explanatory and predictive power. Despite a comparatively low sample size in terms of populations, our results were based on a large number of individuals and were supported by a robust statistical approach. We can conclude that differences among the three species of Globularia could be related to the combined effects of several ecological variables and might not have taxonomical value. Our novel approach provided an ecological interpretation on a species complex that makes up a continuum of forms within the environmental framework of the Mediterranean basin.

“…Leaf gas exchange and storage in P. maritimum are also regulated by aerenchyma tissue within leaf inter-vein spaces that acts by maintaining air circulation and relative humidity in leaf tissues and preventing leaf overheating. 24 Also, leaf adaptation to dry coastal environments resulted in vascular elements ensuring efficient water supply to the photosynthetic tissues. 24 As the flowers open at dusk, 25,26 release a strong scent during the night.…”

[27][28][29][30] Although, several aspects concerning pollination, pollen morphology, seed dispersal and germination, phytochemistry and genetics of P. maritimum have been investigated, 31,32 there is a scarcity of data on the ecophysiological traits of P. maritimum inhabiting maritime sands; therefore, much is still to be discovered.…”

On Pancratium maritimum (sea daffodil, sea lily, sand lily)

The perennial geophyte sea daffodil, sea lily or sand lily (Pancratium maritimum L.) is a flowering species during the dry summer, widely distributed along Mediterranean seashores and grown in a wild stage. Populations of sea daffodil are exposed to sea breeze, salt spray, water shortage, strong solar radiation, elevated temperatures, substrate instability and moving sand. Also, it is expected that excessive tourism and human-induced activities will constrain the development of populations of P. maritimum, which have resulted from a long-term evolutionary process. P. maritimum exhibits large white flowers of a great aesthetic value during dry and hot summer weather conditions, when simultaneously flowering plant taxa are scarce. The buds remain protected below the soil surface on the underground perennial organ and the growth period alternates with a period of dormancy. The above-ground organs and tissues are exposed to harsh, ambient conditions and the large inflorescences of remarkable beauty and fragrance carry particular ornamental worth and thus economic value.
