This plant is known to occur in parts of South America, in Chile it occurs from Quillota to Cauquenes (32 to 35°S) between 190 and 800 m above sea level, a specific location of occurrence being in central Chile within the Cerro La Campana forests in association with the endangered Chilean wine palm, Jubaea chilensis.[2]
It is an evergreen tree or that measures up to 15 m (50 ft) tall and over 2 m (80 in) in diameter, soft, thin and brown bark, with deep vertical cracks, it is one of the few genera of asteraceae which are trees.

The flowers are white and hermaphrodite, 5 stamens with the anthers attached. The fruit is a cylindrical achene about 3–3.5 mm long and 1 mm wide, pubescent, reddish pappi 5 mm long.

Dasyphyllum excelsum es una especie de árbol endémico de Chile, denominado tayú del norte, palo santo y tunilla.
Es un árbol perenne siempreverde, de corteza blanda, grisácea y con fisuras longitudinales profundas. Tallos jóvenes cubiertos por pelos blanquecinos. Tiene hojas alternas, coriáceas, de color verde oscuro, con borde entero y pubescente, forma elíptica aovada con el ápice agudo que termina en un mucrón, base cuneada o redondeada, glabras en ambas caras cuando adultas, densamente pubescentes cuando jóvenes. Dotadas o no de 2 espinas (estípulas modificadas) caducas, en la base de las hojas.
Se conocen dos grandes áreas donde se le encuentra, la meridional desde Molino Viejo (VII Región) hasta Pichilemu (VI Región), la septentrional desde el Valle de Casablanca hasta el cerro La Campana.
Es una especie poco frecuente, propia de las partes más húmedas dentro del bosque esclerófilo, siempre en quebradas. Tiende a formar masas puras. Uno de los mejores lugares donde observarla es en el sector Granizo del parque nacional La Campana, V Región. Se piensa que la distribución actual de la especie es solo una fracción de la que habría tenido en el pasado. Actualmente está considerada en la categoría de “vulnerable” entre las plantas amenazadas de extinción.
Junto al trevo (Dasyphyllum diacanthoides), también endémico, son los únicos árboles del género Dasyphyllum en Chile (familia Asteraceae, subgénero Archidasyphyllum).
