Tliere are some interestinjjf sjiccies in the extreme soutliwesteru por- 

 tion of this district that, as tar as yet known, seem bart^ly to have crossed 

 the Kansas line in their distribntion nortliward. A i>i»rtienhuly interest- 

 ing- locality, in whicli alone some of thtise sjx'cies have so far been 

 found in Kansas, is the I'oint of llocks, a series of rocky bluifs Juttin<^' 

 <ait on tlie nortli side ol' tlie Cinnirron River, near tlie Territory line, in 

 Morton Connty, at which place theheadipiarters of a niunber of cattle 

 men have been estiiblished for some time. 1 shall mention some of 

 these species tliat 1 noted at this place and in a few other localities. 



Kramer la sccundijlora DO. is common from Guthrie to Kinj4fisher, 

 Okla., and westward, but collected in ivansiis only at Point of Jlocks, 

 The followinii' have also been found so far oidy at l*oint of Hocks: 

 I'Jriof/ontiin lavknixjijuHm Ton-., lierldndicra li/rata lientli., and Pefalo- 

 Hiemon violaeean Mx., viw. tenuis (Jonlter. The last one, desi-ribcd by 

 (Joulter in his Manual of the Pliancrogranis and !*teridophytes of 

 western Texas, is common farther south and west in Neutral Strip 

 and Texas. A singnlarly dwarfed form of Ouiothera serrulata Nntt. is 

 also fonnd at Point of liocks, which is common on y;ypsnm hills in 

 Indiiin Territory and in Neutral Strip and Panhandle, but seen nowhere 

 else in Kansas, (■onrolriilu.s iiu-anu.H Vald also has so far betMi found 

 (udy in ^Morton County, and Pedis aiujustij'olia Torr., and Franscrla 

 discolor Nutt. only in iSeward County, besides others. 



NEUTEAL STRIP (BEAVER COUNTY, OKLA.). 



This district exliibits more fully the prevailing;- species of the south- 

 western Great Plains, Following* the Cimarron lliver westward, the 

 species already mentioned as barely crossing* the Kansas line first 

 become more common, then other new species a])pear, and finally, the 

 valley of the Cimarron assuming canon form, an<l reaching the mesas 

 termimiting the spurs of the mountains, the tlora presents an appear- 

 ance (juite similar to that of eastern Xow Mexico and the canons of 

 Texas Panhandle. 



About 50 miles up the river Irom JMorton County, Kans., two or 

 three species of "tree cactus" are first found, also a new Mentzelia, 

 M. mult Iff ora Gray, Paronychia scssili flora ^ntt.^ Desmanthus Jamesii 

 Torr. and Gray, several interesting ferns among the mesas, anew grass, 

 Li/curus phleoiden llliK., etc. Besides, nearly all the species found in 

 ^Morton, Stevens, and Seward ((unities, Kans., now become very com- 

 mon. 



On the divide between the Cimarrcm and North Canadian great 

 patches of Hi/inenopappus Jlavesccns Gray occur, tilling the air with 

 their pungent odor. Jn the same region Eragrostis oxylepis Torr. and 

 Muhlcnhergia graeillima Torr. are quite common, as well as Gaillnrdia 

 pinnatijida Toit., and a variety of Chrifsopsis rillosa^ Kutt,, while Hoff- 

 manscggia stricta Benth. grows in patches scattered about.
