 nal spikes; pistillate flowers in axillary clusters; fruiting bracts mem- 

 branous, ovate, acute, entire, loosely closed over the utricle, but not 

 united, 1$ lines long or less. 



Not uncommon on sandy beaches from Point Reyes and about San 

 Francisco Bay, southward to Santa Cruz, Setchell, and Santa Monica,

6. ALLENROLFEA O. Kuntze. 

 An alkaline shrub with alternate leafless jointed branches; the 

 branchlets fleshy and green with short scale-like leaves. Flowers 

 perfect, arranged spirally by threes in a crowded spike, in the axils 

 of fleshy subsessile bracts. Calyx of 4 (or 5) concave carinate 

 imbricated sepals, more or less united. Stamens 1 or 2, with slender
