Sesuvium portulaca strum L., belonjiiiif^j to jiii order {Ficoulca') clinr- 

 iicterized l),y fleshy, Rucculeiit ])l:itits, i« very fitMiueiit in Kanaas salt 

 marshes and ou the Great Salt IMain of the Ciniaiion, and is strictly 

 characteristic of such localities, acc^ording to my observations. Glaujo 

 maritlma L. is also re])orted from Kansas and known to bo a character- 

 istic salt-marsh plant. T have not observed it myself. 



Clcomella (mgustiJ'oUa Torr. is common in alkaline soils, but not at 

 all limited to snch localities. 



PLANTS CIIAEACTEIIISTIC OF SANDSTONE OTTTGKOP8. 



In the central and eastern portions of the Indian Territory are small 

 surface outcrops, usually of sandstone, at the summits or on sides of 

 hills, or even scattered over the f^eneral level of the country, wliich are 

 always clothed by a vef,a^tation entirely distinct from that of the sur- 

 rounding soil. But I have only observed this ])e(;uliarity in the Indian 

 Territory, and i)robably luive not yet the required facts to make it a 

 matter of very much importance. 



I shall name a few of the spe(de8 most strikinjj;ly characteristic ot 

 these localities that liave come under my observation. These outcroi)a 

 are especially noticeable about Guthrie and Oklahoma City, where 1 

 have collected the following species: ]<^tnna hispid am Gray, Erax proli- 

 fera. Kutt., Euphorhia pcpHdion Kng., Linum HcrJandivH Hook., and 

 several others of less importance. In these same outcrops and in the 

 eastern part of the Territory I have collected some others, which are 

 also found in the western Great Plains, such as Aciiiiella Unvarifolia 

 Torr. and (iray, and ?Jvolvulus argenteuH Pursh, both at Oklaln^ma City, 

 and (Enoiliera linifoUa Nutt., Bumcx aceiOHcUa L., Phacelia parriflora 

 Pursh, rhacelia strictiflora Gray, and others, in the Creek ^Nation.
