Trifolium macrocephalum is a species of clover known by the common name largehead clover or bighead clover native to the Great Basin region of the western United States.[1]
Description
Trifolium macrocephalum is a rhizomatous[2] perennial herb taking an upright form. The herbage is hairy. The leaves are made up of five or six[2] thick oval leaflets each measuring up to 2.5 centimeters in length and have short teeth at their margins and often a pale transverse mark.
The inflorescence is crowded, egg-shaped and up to 5 or 6 centimeters long. Each flower has a calyx of sepals with lobes narrowing into bristles which are coated in long woolly hairs. The flower corolla may be nearly 3 cm in length and is pink to lavender in color,[2] or sometimes bicolored. It blooms early in spring.[2] As both the Latin and common names suggest, the flower head is unusually large for a clover.
Distribution and habitat
Trifolium macrocephalum is native to the Great Basin region of the western United States, from Washington to northern California , and Nevada to Idaho. It occurs in several types of habitat, including sagebrush scrub, juniper woodland, yellow pine forest, and mountain woodlands. It prefers thin-soiled, rocky areas.[2]
