Campanula cana from Manali-GS28062022-3

[Gurcharan Singh]

Campanula cana Wall.

All three species on which there has been enough discussion in our group were named by N. Wallich, and obviously first illustrated in his Wallich Catalogue, 1812, which being without descriptions were treated as Nomen Nudum unless validated by author himself or some other author. C. pallida Wall, was first validly published in Asiat. Res. 13: 375 (1820), C. colorata Wall. in in W. Roxburgh, Fl. Ind. 2: 101 (1824) and C. cana Wall. in Roxburgh, Fl. Ind. 2: 101. (1824). FBI treated them under two species C. colorata Wall. (syn: C. pallida). However, beause of being published earlier, C. pallida gets priority as accepted name over C. colorata.

     The two species C. pallida and C. cana, both represented in Western Himalayas can be separated as under as per Eflora of China:

1. C. pallida: Stem single, rarely two or more; leaves hispid, lower often with winged petiole, calyx lobes triangular to subdeltoid, hispid outside, often toothed. 

2. C. cana: Stems usually several from base; leaves white soft hairy, lower not with winged petiole, calyx lobes subulate to narrowly triangular, softly hairy outside, usually not toothed.

Here is C. cana, photographed from Manali, 29-10-2009.
