Howell's clover is a California native perennial found in northern Klamath Ranges, northern North Coast Ranges, and northern California Ranges in wet or shady meadows, sedge habitats, and alder swamps at elevations of 800 to 1,800 meters. Flowering from July to August, this plant produces green-white to pink flowers in compact heads 1.5 to 3 centimeters long, with blossoms eventually becoming reflexed. Growing robustly with erect glabrous stems, it reaches a substantial size with green stipules on mid-leaves measuring 1 to 2.5 centimeters long. Its leaves feature elliptic to ovate leaflets 4 to 10 centimeters in length, arranged along the stem with notable complexity. The plant produces a distinctive calyx 3.5 to 4.5 millimeters long with slender lobes nearly as long as its base tube.
