Morphological features of the endemic Erodium somanum are investigated based on the specimens collected from natural populations from Soma in Manisa. Almost all morphological characteristics are expanded and some morphological characteristics are firstly determined in this study. E. somanum is a dioecious species and in this study drawings of male and female individuals are given for the first time. An umbel is 3-5 flowered in female plants and 6-11 flowered in male plants, pedicels accrescent to 20-25 mm in fruit. Flower morphology was identified in detail and drawings are given for the first time. Stigma color ranges from yellow to red in populations. The fruit is long-beaked 4.8-8 cm, stout and adpressed pilose, glandular below. Mericarp morphology investigated for fruit characters has a special diagnostic value for systematic studies. The mericarp micromorphology and seed micromorphology were determined for the first time. Mericarp size 9-12 mm, mericarps have two apical shallow pits (foveoles) without furrow beneath. Mericarp surface ornamentation is foveate with crowded bristles of dissimilar size, some longer and others shorter. Mericarp pit is crowded with eglandular hairs and some sparse, long-stalked glands which are also at the start of the awn. Seed size is 4.5-6×1.5-2 mm, seed type is narrowly ovate, seed surface is ruminate.
