Microseris heterocarpa, known by the common name grassland silverpuffs, is a species of flowering plant in the family Asteraceae.
Distribution
It is native to southwestern North America, where it can be found in various areas of California , and parts of Arizona and northern Mexico. It grows in open habitat in chaparral, woodlands, grasslands, desert, Sierra foothill, and inland canyons.
This species is also found on Guadalupe Island, a Mexican island in the Pacific Ocean.[2]
Description
Microseris heterocarpa is variable in morphology. In general, it is an annual herb with a basal rosette of large leaves. The inflorescence arises on a tall peduncle bearing a solitary flower head. The head is lined in hairless phyllaries and contains many ray florets, often over 100, in shades of yellow or white.
The fruit is an achene with a brown, gray, blue, or purple body tipped with a pappus of five long, spreading scales, the whole unit measuring 1 or 2 centimeters.
This species is suspected to be a hybrid between Microseris douglasii and Uropappus lindleyi which may have evolved independently, possibly three times.[3] The plant comes in a wide variety of appearances with variations in florescence properties and size, as well as height, ranging on a scale between both of the suspected parent taxa.
