Description

1.1. Chamaenerion angustifolium (L.) Scop.

(Fig. 2A).

Epilobium angustifolium L. ≡ Chamerion angustifolium (L.) Holub (1972: 86).

Lectotype (designated by Raven 1962a):—Habitat in Europea boreali, Herb. Linn. No. 486.1 (LINN digital image).

Distribution: —Widely distributed in the Pan-Himalaya region.

Note:Chamaenerion angustifolium have two subspecies, diploid (n = 18) C. angustifolium subsp. angustifolium and tetraploids (n = 36) C. angustifolium subsp. circumvagum (Mosquin 1966: 167) Moldenke (1973: 289). Triploids occasionally occurred in diploid and tetraploid contact zone (Sabara et al. 2013). These two subspecies are delimited by morphology (Mosquin 1966) as the following key.

C. angustifolium subsp. angustifolium
