Low rigid diffusely branched desert annuals. Leaves alternate, linear to cuneate, pin- 

 nati fid-toothed with the lower divisions reduced to slender bristles, the upper bristle- 

 tipped. Flowers in terminal few-flowered bracteate heads, the bracts foliaceous with 

 bristle-tipped lobes or teeth. Calyx-lobes equal, spinescent-tipped, the tube scarious be- 

 tween the angles and splitting to the base, then appearing as 5 distinct sepals. Corolla 

 showy, tubular-funnelform, more or less 2-lipped, with 3 lobes in the upper lip and 2 lobes 

 in the lower, or sometimes nearly regular with the lips obscure. Stamens 5, inserted in

 3-sided. Seeds 2-9 in the capsule, mucilaginous when wet. [Name in honor of Reverend 

 Father Langlois of Louisiana.]
