Thalictrum minus has been reported from mainland Alaska (E. Hultén 1968); we have been able to confirm its occurrence only in the Aleutian Islands.

Initially pendent, the flowers become erect. The beak is 0.75-1 mm, much shorter than the achene, and not fimbriate.

Thalictrum minus

provided by wikipedia EN

Thalictrum minus, known as lesser meadow-rue,[1][2] is a perennial herb in the family Ranunculaceae that is native to Europe, Northwest Africa, Yemen, Ethiopia, South Africa, Southwest Asia, and Siberia. It grows on sand dunes, shingle, coastal rocks or calcareous grassland, cliffs and rocky gullies at up to 1,600 to 3,000 m (5,200 to 9,800 ft) elevation at southern latitudes.[3] It grows to 30 cm (0.98 ft) tall with erect stems and 1 cm (0.39 in) leaves that are highly subdivided, 3-4 ternate to pinnate.[4]

The plant contains an alkaloid 'Thalidisine', which is also present in other Thalictrum species.[5]
