Patulum

Greene. Lvs. as in the foregoing, nearly, but stout scapes only 3-7in. high: umbel very many fld.: corolla large, with pale cream-colored segments, sometimes purplish tinged: tube of a dark, velvety maroon-purple: anthers very short and broad, of a deep blue-purple: capsule subglobose, hardly surpassing the calyx. Plains of the interior of middle Calif.

These three species have, among other peculiarities, that of propagating by their roots. Each root, after flowering time, thickens and shortens, detaches itself from the ground and forms a bud at the end, thus becoming a new plant.
