INTRODUCTION. 



Agrostological Notes was the general title of Circular No. 27 which contained 

 several short papers of purely technical nature and the same title is here adopted 

 for a series of papers of similar character as follows: 



1. Some Species of Grasses published by by S. B. Buckley. 



2. Notes on Calamovilfa. 



3. Three New Species of Panicuvi. 



4. A new Species of Poa. 



5. Some Changes in Nomenclature.

In ISGG Mr, S. B. Buckley published a small octavo volume of 81 

 pages, with an appendix of 4 pages, that was issued from the office 

 of the "State Gazette" at Austin, Texas, under the title "A Pre- 

 liminary Report of the Geological and Agricultural Survey of Texas." 

 The appendix, which is paged separately, is the part of the report of 

 interest to agrostologists. In it one genus and nine species of Texan 

 grasses, supposed b}^ the author to be new, are described. These 

 species, which for some reason were not included in Index Kewensis, 

 are as follows : 



Schleropelta Buckley, Prel. Rept. Geol. and Agrl. Surv. Texas, App. 1. 1866. 

 =Hilaria H. B. K. Nov. Gen. et Sp. PL 1: 116. LSiT). 



Schleropelta stolonifera Buckley, 1. c.=Hilaria ceucliroides H. B. K. 1. c. 117. 



Pappophorum (Polyrhaphis) vaginatum Buckley 1. c. This is the earliest pub- 

 lication of this species and Buckley's name should be retained. Pappo- 

 phorum apertuiu Munro in Scribn. Bui. Torr. Bot. Club, 9: 148. 1882, is a 

 synonym. See Merrill, U. S. Dept. Agr. Div. Agros. Cir. 32: 9. 1901. 



Cenchrus setoides Buckley, 1. c, 2=C'ej?(7//M.s inyosiiroidcs H. B. K. Nov. Gen. 

 et. .Sp. Pi. 1: 115. t. .15. 1815. 



Calamagrostis (Deyeuxia) longirostris Buckley, 1. c. "Culm erect, a little 

 scabrous, half a foot high, sheaths a little scabrous, and about ecpial to the 

 internodes; ligula elongate, membranaceous and subentire; leaves plain or 

 convolute, scabrous, shortly pubescent above, 4 to 6 inches long, and 2 to 3 

 lines l)r()ad; panicle terminal, somewhat open and interrupted, .3 to 5 inches 

 long and 8 to 12 lines broad; rachis terete, pubescent; glumes subequal, lan- 

 ceolate, acute, longer than the florets, scrabrous on the back, margins and 

 apex hyaline ; tipper 1 to ;{ nerved, lower palea o to 5 nerved, shortly pilose 

 at the base, hyaline upon the margin, apex bifid, below the middle long 

 aristate; awns twisted, jointed and double the length of the florets; lower 

 internodes of the rachis about 8 linos in length : upper intervals 2 to 3 lines 

 long; long estrays naked near their bases and densely spiked near their 

 summits; spikelets about 3 lines long." 



The identity of this species is in doubt.
