 of its resemblance to that genus.)

 Bracts with strong transverse rihs from the midrib to the conspicuous 

 marginal nerve, the spaces between the ribs silvery-scarious or trans-

Bracts whitish-scarious, the ribs converging toward the apex, at least in 



the inner bracts ; corolla-tube much surpassing the calyx 



2. M. Brewcri. 



Leaves undulate; seacoast species 3. M. undulata. 



Perennials.

 recurved. — Merced plains of the San Joaquin Valley.
