This study examines the anatomical structure of the glandular apparatus in Satureja cuneifolia Ten., as well as the chemical composition of the essential oil derived from it. Leaves were collected from a population in Dalmatia (Croatia). Anatomically, the glandular scales feature a unicellular base, a unicellular stalk and a 12-celled head. Each glandular apparatus was observed to be surrounded by epidermal cells. Qualitative and quantitative GC-MS analysis of the essential oil showed that linalool, carvacrol and p-cymene were its main constituents.

A number of anatomical adaptations to an arid habitat can be noted in the microscopic structure of Spartium junceum L. vegetative organs. The xerophytic adaptation of the leaf is seen in its short life and the transformation of its inner structure, with palisade parenchyma dominating. The top part of the stem has taken over the leaf function, while sclerenchyma fiber and conductive elements occupy most of its secondary units. A peculiar feature of the primary structure of the root is its incompletely developed endodermis, and the secondary structure points to its storage and mechanical roles. GC/MS analyses of the essential oils showed that they consist mainly of monoterpene hydrocarbons with α-thujene as the main compound. The essential oils also play a xeromorphic role in this plant species.
