Nothoscordum montevidense Beauverd (1906) : 1011 — Cabrera (1968): 515.

Cryptophyte, native with distribution in the Southern Cone Region of South America; previously recorded from Buenos Aires province but not from mountainous areas.

Characteristics. Perennial herb, 5–10 cm tall. Bulb solitary, globose, ca 1 cm in diameter. Sheaths short. Leaves to 10 cm long, parallel-veined, linear, with apex acute. Peduncles erect. Inflorescence: an umbel, with 2–10 flowers. Tepal perianth yellow, 3.5–5 mm long. Anthers to 2 mm long. Fruit: a capsule.

Comments. This is an infrequent species in the study area. It grows in shallow to moderately deep, damp soils on rocky and grassy slopes with other white-flowered Nothoscordum species. Cabrera (1968) reported N. montevidense from Buenos Aires province but not this subspecies. Hurrell (2009b) reported the existence of 3 subspecies in the Rioplatense region of northwestern Buenos Aires province. Our Paititi specimens belong to N. montevidensis ssp. latitepalum because they are relatively tall and present flowers with wide yellow tepals.
