Malesherbia lactea
Species of flowering plant
Malesherbia lactea is a perennial geophyte native to the La Rioja and San Juan regions of Argentina and the Antofagasta and Atacama regions of Chile.[1][2][3] It has ovate leaves that end in a sharp point.[2] Similar to other members of Malesherbia, the flowers are red and white, and tubular in shape.[2][4]
There are two varieties of M. lactea, var. crassicaulis (Bull-Hereñu) and var. lactea.[1][4] Variety crassicaulis differs from var. lactea in its thicker and longer stem. It grows at lower altitudes (2700 m) than var. lactea (2500 – 4300 m) and is considered more robust.[4][5][6][3] Variety crassicaulis only grows in Atacama, while var. lactea grows throughout the native range of M. lactea.[5][6] It is hypothesized that var. lactea differs in ploidy level, though this has not been supported by molecular work.[4]
Variety crassicaulis was originally classified as Malesherbia rosulata.
