A new record for the fl ora of Turkey: Lathyrus atropatanus (Leguminosae)

Transcaucasia, are very similar to each other; they are even thought to be synonyms (Davis, 1970). It was collected from Van Province in 2008. L. atropatanus is diff erent from L. nivalis mainly in its dense adpressed indumentum. First attempts were made to identify the collected samples using Flora of Turkey (Davis, 1970; Davis et al., 1988; Güneş & Özhatay, 2000). According to the identifi cation based on the Flora of Russia (Komarov, 1948), it was concluded that it is L. atropatanus, recorded for the fl ora of Turkey for the fi rst time. New records and new taxa of articles have increased with revision studies recently (Aytaç & Duman, 2010; Kürşat et al., 2011, Özhatay et al., 2011). Lathyrus atropatanus is closely related to Lathyrus nivalis. It diff ers from the latter in having the leafl ets (5-)11-28 × 1-4 mm (not 15-63 × 1-5), stipules 5-15(-20) × (0.5-)1-3 mm (not 5-25(-27) × 0.5-5), peduncle 3.3-10 mm (not 4.1-20.6), fl ower length (15-)20-26(-27) mm (not 18-24), fl ower purple-dark blue (not violet or lilac), wings whitish or clear white (not whitish), calyx hairy, (6-)7-8 mm (not glabrous, 6-10), seeds prolate, P/E = 1.43 (not prolate, P/E = 1.52), pollen shape subprolate, P/E = 1.30 (not spheroidal, P/E = 1.12), pollen P × E = 42.07 × 32.34 μm (not P × E = 39.00 × 34.84), chromosome number and types 2n = 14, m,m,m,m,sm,m,m (not 2n = 14, m,m,m,sm,m,m,m)
