Genus Lepidium L. is one of the largest genera in the Brassicaceae, consisting of ± 175
species worldwide (Bowman et. Al., 1999). It is distributed wordwide,mainly in temperate
and subtropical regions. The genus is poorly represented in Arctic climates, and in tropical
areas it grows in the mountains (Mummenhoff et. Al. 2001). According to Flora of Turkey,
14 taxa is disturbed in Turkey (Hedge, 1965 and Güner 2000).
In this study is shown distribution of Turkish Lepidium L. which are L. campestre (L.) R.Br.,
L. spinosum Ard., L. sativum subsp. sativum L., L. sativum subsp. spinescens (DC.) Thell., L.
ruderale L., L. perfoliatum L., L. vesicarium L., L. caespitosum Desv., L. cartilagineum
subsp. cartilagineum (J. May.) Thell., L. cartilagineum (J. May.) Thell. subsp. crassifolium
(Waldst. & Kit.) Thell., L. latifolium L., L. lyrtaum L., L. graminifolium L., L. virginicum L.

As part of a recent revision of the genus Scutellaria L. (Lamiaceae) in Turkey, the taxonomic
revision of Scutellaria L. section Salviifoliae (Boiss.) J.R.Edm., including a key to the
species, detailed morphological descriptions, distribution maps, and illustrations, is presented
here. The study is based on herbarium materials kept at the herbaria AEF, ANK, BM, EGE,
GAZI, HUB, ISTE, ISTF, JE, K, LD, OXF, W and WU, and field observations. The section
Salviifoliae is considered to comprise four species, distributed in the range from East
Mediterranean to Caucasus. Of these species, S. salviifolia Benth. is endemic to Anatolia. S.
diffusa Benth. and S. heterophylla Montbret & Aucher ex Benth. are restricted to East
Mediterranean. S. pontica K.Koch is only occurs in Euxine province. These four species are
distinguished from one another by their habit, corolla and leaf morphology. The
phytogeography of the section and close affinities of the species within the section are
discussed. The section is characterized by impressed-veined leaves resembling those of the
genus Salvia and secund flowers in one-sided inflorescence. The members of the section
Salviifoliae are 5-45 cm height, prostrate to ascending, and perennial herbaceous plants, found
in a variety of habitats, such as clearings in Pinus, macchie, scrubs, rocky and stony slopes,
grassy slopes, and alpine pastures. Pollen and nutlet characteristics of the species are also
studied in detailed with light and electron microscopies. The pollen type of the section is
tricolporate. The pollen shapes of the species are prolate-spheroidal or oblate-spheroidal.
Sculpturing in the mesocolpium and the apocolpium is bireticulate. Polar axis vary from 17.5
to 29.7 µm and the equatorial axis from 19.3 to 29.5 µm. Nutlets are grey-black, ovoid, ca. 1.5
mm, and have adpressed hairs covering completely the surface.
