described and named, doubtfully, as Graphcphornm flextiosum. 

 Next, a ^ft\N specimens were collected by Rothrock and Wolf, on 

 Wheeler's Exploration, in the San Luis Valley, Colorado, in 1873. 

 From these sources were obtained all the specimens of which I 

 nave knowledge in existing herbaria. I have been for years past 

 hoping that it would again be found, and its rediscovery at Gar- 

 ^t\\ City is therefore very satisfactory. Here it is in abundance, 

 ■rrobably it is common enough in similar situations at many points 

 on the Canadian and Arkansas rivers. The leaves are thick and 

 "gid, channelled and terminating in long, involute points. It 

 should hereafter become well known to botanists. 



Confusion has sometimes occurred as to the distinction be- 

 tween Sporobohcs cuspidatus and 5. depaupcratus, ( Vilfa, Torr.). 

 found abundance of the former on the prairies of Dakota. It 

 grows m strong tufts, with erect culms and appressed leaves, and 

 a long, slender panicle, and approaches Mtihlenbcrgia Wrightii ; 

 indeed, it belongs rather to Mtihlenhergia than to Sporobolus. S. 

 depanperatiis is a species oif the Rocky Mountains, with decum- 

 bent culms, shorter panicle, and glumes wanting the long cuspi- 

 date point. Geo. Vasey.

This very neat and interesting collection will be a welcome 



surprise to those who are not already familar with Mr. Hough's 



beautiful wood-sections, and the accompanying pamphlet, with 



"lany illustrations supplemented by a glossary and descriptions 



of species, makes a complete little text-book. A novel feature 



^ill be noted in finding three keys, one based upon the flowers, 



one upon the leaves and a third upon the fruit, so that having 

 either, a novice may find his way made easy to determine the 

 specimen.
