Ichtyoselmis macrantha (also spelled Ichthyoselmis; formerly known as Dicentra macrantha; large-flowered dicentra) is the only species in the genus Ichtyoselmis.

It is a perennial plant growing from a long rhizome, native to woodland and glades at elevations of 1,500–2,700 metres (4,900–8,900 ft) in northern Burma and southern China.

In Sichuan Province, China, it is known as goldfish plant, because of the shape and color of the flowers.

[2] Although the correct spelling of the Greek word uses th (theta), the scientific name uses t. Leaves are divided in threes twice or three times and toothed.

Flowers hang at the end of leafy stems up to 1 m (3.3 ft) tall in cymes of 3-14 flowers and have two long, thin sepals and four cream to pale yellow petals.
