Abstract
The aim of this study was to determine the morphological and autecological characteristics of Salvia rosifolia Sm. which is an endemic plant (Lamiaceae) distributed in Erzurum and its environs. Morphologically, it was observed that the species had a perennial root system, the herbaceous stem was ascending, unbranched, leaves pinnatisect, oblong-eliptic, glandular and eglandular hairs were present on the both surface of leaves. Bracts were ovate-acuminate and bracteols lanceolate. It was observed that calyx was campanulate and corolla bilabiate and also species contained two A type of stamen. Ecologically, the chemical and physical analysis was carried out on soil and plant samples collected from 22 different localities in Erzurum and its environs. Present results showed that the plant generally prefers loamy, sandy-loamy and sandy-clayey-loam textural soils, with a slightly alkaline or neutral pH. They also preferred non-saline or slightly saline soils which were both medium and rich calcium carbonate. The result obtained from soil and plant analyses were evaluated statistically and it was found that there was a relation between the quantities of phosphorus, nitrogen and potassium and plant abundance and distribution.
