An attracti\'e plant evidently with close affinity to .S'. occicUn- 

 talc ; though not actually proved to be distinct by the few speci- 

 mens before me I feel little hesitation in giving it a name. It ap- 

 pears to be less glaucous than S. occidoitalc with narrower more 

 nimierous and crowded leaves and stems of thinner texture^ 

 slenderer roots, larger often red-purple spathes and narrower 

 mostly more unequal bracts, the inner one especially more attenu- 

 ate and acute. The higiily colored spathes give the plant much 

 the aspect of forms of S, jiiucroiiatuDi of the East. 



The sheet of specimens cited from Nevada shows fruiting plants 

 which differ strikingly from the other examples, yet for the present 

 I can refer them nowhere else than here. They are very slender 

 with long somewhat flexuous stems and very narrow deflected 

 spathes having the lower part for about 5 mm. scarcely or not at 

 all broader than the stem. 



SisvRiN'ciiiUM HALOPHiLUM Greene, Pittonia 4 : 34. 17 Mr. 1899 



Very pale dull green and white glaucous, mostly low, 10-20 

 cm. high, stiff and erect or nearly so, the thickened roots densely 

 clustered ; leaves half the height of the stem or longer, stiff 

 and thickish, often slightly curved, 1-3 mm. wide, strongly closc- 

 striate, smooth-edged, attenuate, acute, In age developing hard- 

 pointed tips : stem from less than i mm. to 2 mm. wide, wiry, as- 

 cending or outcurved, margined to narrowly winged, the wings thick 

 and firm, smooth-edged : spathes erect, green, rather flat and sharp- 

 edged, 2-4 mm. wide, the bracts striate, subequal or the outer 

 one slightly prolonged; outer bract 15-22 mm. long, usually 

 somewhat convex, acuminate to a short-pointed mostl}' obtuse 

 often incurved apex, hyaline-margined, united clasping for 3-4 

 mm. at base ; inner bract more broadly hyaline, abruptly acute to 

 obtuse ; interior scales more than half the length of the inner 

 bract : flowers 4-8, small to medium-sized, perianth apparently^
