Munzothamnus is a monotypic genus[2][3] of flowering plants in the family Asteraceae containing the single species Munzothamnus blairii, which is known by the common name Blair's wirelettuce, or Blair's munzothamnus. It is endemic to San Clemente Island, one of the Channel Islands of California. It grows along steep, rocky cliffsides and canyons on the island. It is a shrub producing a fleshy, woolly stem usually over a meter in height, often approaching two meters. Leaves occur in tufts at the ends of the stem branches. They are up to 15 centimeters long, oblong in shape, and sometimes very shallowly lobed. They are woolly when new but lose their hairs and become shiny green with age. The inflorescence is a large array of up to 35 flower heads. Each head has a cylindrical base under a centimetre long and contains 9 to 12 light lavender or pinkish flowers. Each flower is a ray floret with an erect tube and a strap-shaped ligule with a toothed tip. The ligule is just under a centimetre long. The fruit is a cylindrical, ribbed achene with a white pappus.
Like many Channel Islands endemics, this plant was reduced to rarity by the presence of feral goats on the islands; the goats have been removed.[1]
The Latin name of Munzothamnus refers to the American botanist Philip A. Munz.[4][5]

Munzothamnus es un género monotípico[2][3] de plantas herbáceas perteneciente a la familia Asteraceae. Su única especie: Munzothamnus blairii (Munz & I.M.Johnst.) P.H.Raven, es originaria de Norteamérica. El género fue descrito por Peter Hamilton Raven y publicado en Aliso 5(3): 345, f. 6, en el año 1963.[4]
Es un arbusto con tallo lanoso generalmente de más de un metro de altura, aproximándose a los dos metros. Las hojas se presentan en forma de manojos en los extremos de las ramas del tallo. Tienen hasta 15 centímetros de largo, de forma oblonga, y, a veces superficialmente muy lobuladas. Son lanosas cuando son nuevas, pero pierden su pelo y se convierten en color verde brillante con la edad. La inflorescencia es una gran variedad de hasta 35 capítulos de flores. Cada cabeza tiene una base cilíndrica de un centímetro de largo y contiene de 9 a 12 flores de color lavanda o rosado. El fruto es cilíndrico, es un aquenio estriado con un blanco vilano.
Es endémica a la isla de San Clemente, una de las islas del Canal de California. Crece a lo largo de rocas escarpadas, riscos rocosos y barrancos de la isla.
Al igual que otras muchas especies endémicas de las Islas del Canal, esta planta se redujo a la rareza por la presencia de cabras salvajes en las islas, aunque las cabras ya se han eliminado.[5]
