TWO NEW SUBSPECIES OF TROPAEOLUM (TROPAEOLACEAE) FROM THE IV REGION (COQUIMBO), CHILE
Two new subspecies of Tropaeolum hookerianum Barn. are described. Apart from T. hookerianum subsp. austropurpureum presented here, only one other Andean-Pacific temperate Tropaeolum, T. azureum Bert. ex Colla, has blue to purple flowers. The second taxon, T. hookerianum subsp. pilosum, is distinguis...
