M. LAEVI.S Curran, Proc. Cal. Acad. ser. 2, 1: 235 (1888). Ojybaphus laevis Benth. Bot. 

 Sulph. 44 (1844), type loc, Magdalena Bay. We have not seen the type but in a specimen 

 from the type locality (Lung 28), which is essentially glabrous as described for the original, 

 the very slightly unequal involucral lobes are narrower and more acuminate than in M. cali- 

 fornica but no more unequal in size than in some specimens of the latter species which is, 

 furthermore, often nearly glabrous. The two forms, M. laevis and M. californica, are probably 

 identical, an opinion long ago expressed in the Proceedings of the California Academy, 1. c. 



M. CEDROSENSis Jepsou n. comb. (Hesperonia cedrosensis Stand. Contrib. U. S. Nat. Herb. 

 12: 362 (1909), type loc. Cedros Island, T. Brandegee). Stems rather slender, these and the 

 leaves retrorsely scabrate; leaves thiekish; fruit subglobose, not conspicuously striate longi- 

 tudinally. Seems no more than a form of M. californica. Attributed doubtfully to San 

 Clemente Island by Standley, 1. c. 



BATIDACEAE. Hvtis Family. 



Low maritime bush or woody plant with opposite entire fleshy leaves. 

 Flowers dioecious, crowded in catkins. Catkins sessile, axillary, disposed iu

1. BATIS P. Br. 



Species 2 or 3, tropical shores. (Greek bntis, the ancient name of some sea- 

 shore plant.) 



1. B. maritima L. Stems erect or ascending from a woody perennial base, 

 i/'2 to 1 (or 3) feet high; leaves linear-oblanceolate, i/> to li/4 inches long; 

 staminate catkins 2 to 4 lines long, their bracts roundish, obtuse, 1 line long, 

 or sometimes broader than long, disposed in 4 vertical rows, persistent ; calyx 

 splitting transversely across the top so as to make an anterior and a posterior 

 lobe, about % line long; staminodia white, nearly as long, with a roundish 

 or triangular-hastate, somewhat cucullate appendage uearlj^ equaling the 

 slender filament; pistillate catkins 1 or 2 lines long, their bracts I'ound-ovate, 

 acute, deciduous; ovaries coherent, in fruit forming a fleshy spikelet 4 to 

 6 lines long.
