8. Chenopodium atripliciforme Murr, Magyar Bot. Lapok 1: 360 (1902).

Lectotype

( Uotila 1993): AFGHANISTAN, Kurrum valley, 1879, J.E.T. Aitchinson 980 (G11875! isolectotypes BM000629112! C, G-BOISS! FI, K! S).

Taxonomic notes.

Murr (1902) cited two distant records (Russian Far East and Afghanistan) in the protologue of C. atripliciforme . We agree with Uotila (1993) that the specimen from the first location (Ussuri) probably belongs to C. bryoniifolium Bunge, which is similar in leaf shape to C. atripliciforme .

Description.

Annual up to 1 m, mostly branched; leaves petiolate (petioles up to 4 cm). Leaf blades triangular, basally truncate or broadly cuneate, entire to erose-dentate. Inflorescence branched, terminal and axillar, slender; clusters consisting of 2-4 flowers or rarely flowers solitary. Fruit 1.2-1.4 mm with papillate pericarp. Seed black, almost smooth with indistinct small pits (Fig. 10C, D ).

Habitat.

Rocky places, forest margins; (1800)2000-3300 m a.s.l.

Phenology.

Flowering: June-September; fruiting: August-October.
