摘要

The object of the present contribution is the taxonomical study of the Family Amaryllidaceae (Liliopsida, Order Liliales) for Santa Fe, which includes 90 genera and about 1000 species of tropical and subtropical regions of the world. The methodology consisted in observation in the field,- analysis of plant collections (Herbaria SF, SI and UNR) and existing literature. Our preliminary results show that the family is represented in Santa Fe by three genera with nine taxons, plus an additional one of doubtful occurrence: Habranthus gracilifolius Herb., H. pedunculosus Herb., H. schuhianus Ravenna (one of the few endemic species in the province), H. tubispathus (L'Her.) Traub, Rhodophiala bifida (Herb.) Traub, Zephyranthes Candida (Herb, ex Lindl.) Herb., Z.filifolia Herb, ex Kraenzl., Z. minima Herb, subsp. minima andZ. seubertii E.P. Hume. The species Habranthus brachyandrus (Baker) Sealy has been mentioned for the province, but no herbarium specimens have been found so far. A distribution map, dichotomic keys for genera and species and some photographs are presented.
