Cryptocoryne legroi

Cryptocoryne legroi de Wit is now regarded as a synonym of C. walkeri, a marsh plant from central Sri Lanka; it is also listed as C. walkeri 'legroi'.¹²⁴ De Wit described it as a separate species in 1970; owing to intermediate forms in the characters of the inflorescences, like C. lutea it is now included in C. walkeri.²³ Its chromosome number of 2n = 42 identifies it as a triploid form of this species; no natural localities are known.⁴

The rosette grows about 10–15 cm tall; the submersed leaves are elongated ovate, pointed and wavy at the margin, glossy olive green above and red to reddish brown below.² The slow-growing, easy-care plant copes with low as well as strong light and suits groups in the foreground and midground.²
