(Matucana haynei herzogiana)
Matucana haynei is a species of Magnoliopsida first described by Christoph Friedrich Otto, and given the simplified Asian name by Nathaniel Lord Britton and Joseph Nelson Rose. Low, globose or shortly cylindrical bodies, either solitary or clustering. The flowers are subapical, usually more or less zygomorphic, diurnal, in various colours, but mainly red, yellow or pink. However, a few species, notably M. oreodoxa, have actinomorphic flowers and were placed in a separate genus - Eomatucana - by F. Ritter. They are reported to flower easily at a young age. All members of the genus cannot tolerate too much moisture and must be watered only during their growing season and when the substrate is dry. They must also be kept warm through the winter or risk losing their roots. Members of Matucana grow quickly and may be grown from seed.
