| 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 distinguished by pilose pedicels, a feature unique among Andean-Pacific temperate species. Both novelties are Chilean endemics restricted to the IV Region (Coquimbo), as also is the nominate subspecies. All three are allopatric, and considered together extend the species' range to the north, to the south and to the east. Their characters and interrelationships pose implications for Tropaeolum evolution which are likely to be of interest to exponents of phylogenetics... |

| Chaetanthera acheno-hirsuta (Tombesi) Arroyo, A.M.R. Davies & Till-Bottraud (Asteraceae: Mutisieae), previously known from the upper limits of the vegetation (>3900m) on the eastern side of the Andes in San Juan Province, Argentina, is cited for Chile from six collections made in the Andes of the III Region (Atacama Region) between 3500-4000 m. The new record for the flora of Chile is based on Chaetanthera pulvinata (Phil.) Hauman var. acheno-hirsuta Tombesi, here elevated to species. Chaetanthera acheno-hirsuta belongs to Chaetanthera subgenus Egania. Its closest relatives, based on morphological characteristics, are C. apiculata (J. Remy) Benth. & Hook.f. and C. acerosa (J. Remy) Benth. & Hook.f. It is distinguished from C.... |
