PLATE 48^. 



Calamagrostis Huttoni^, Hack. (Records of the Albany Museum, Vol. I., No. 5). 



Nat. Order Gramineae. 



Culms in the upper part (which only is present in our specimens) terete, very 

 glabrous, shortly exposed at apex ; sheath of the uppermost leaf rather loose, 

 scabrid ; ligule oblong, obtuse, cleft, about 3 lines long ; blade linear, acute, about if 

 inches long, 1 J line broad, very scabrid, nerves rather thick, excurrent. 



Panicle linear-oblong, wide -spreading, rather dense, suberect, 7 to 9 J inches long, 

 by 14 to 19 lines broad, rhachis scabrid, branches 6 to 8, semiverticillate, slender, 

 filiform, or sub-capillary, erect, broad-spreading, very scabrid, undivided in lower half, 

 then bearing many to very many-spiculate secondary branches. 



Spikelets equally disposed on the branches, rather close together, shortly 

 pediceUed, pedicels clavate at apex, very scabrid. Spikelets lanceolate, 1 J line long, 

 pale green. 



Glumes subequal (lower a very little larger), lanceolate, 1^ line long, expanding 

 to about J line broad, very acute, I-nerved, keel very aculeato-scabrid. Valve a little 

 shorter than the glume (about 1 line long), oblong, obtuse, minutely 4-fid at apex, 

 thin-membranous, 3-nerved, back very glabrous, covered with the long, dense hairs of 

 the callus, muticous (or rarely in upper third producing an erect aristula scarcely 

 exceeding itself) ; pale subequal to the glume, oblong, rather obtuse, bidentate, 

 2-keeled, very glabrous. Anthers almost ^ line long. Appendage of rhachilla about 

 4^0 i^^ch long, densely bearded with hairs 1 line long.

In a note Professor Hackel says : " With the specimen there was a single com- 

 plete flowering stalk, which represents Agrostis lachnantha, Nees, slightly differing 

 from the type. Both grasses therefore grow at the same place, and it is remarkable 

 to notice that almost all characters (leaves, spikelets, relative sizes, form and nervation 

 of the glumes and valves) agree in both, the only difference is in the indument, for 

 Agrostis lachnantha has at the base of the valve only short hairs, and just such hairs 

 at the sides, and on the back ; it is entirely without the prolongation of the axis." 



The drawing so far as the panicle is concerned was made from the specimen 

 kindly lent for the purpose by Dr. S. Schonland, and after its arrival it was 

 noticed by the artist that our specimens, Buchanan 286, Mason 44, and Mason (Wood 

 7323, partly), all classed as Agrostis lachnantha were also mixed with the Calamagrostis^ 

 so that the lower portion of the plant was drawn from Mason's 44. The artist. Miss 

 Franks adds the following description which is wanting in Professor Hackle's descrip- 

 tion : " Culms erect, 2 to 3 feet high, 3 to o-noded, branched from the lower nodes. 

 Sheaths striate, scabrid, glabrous."

 appendage ; 6, pistil, stamens and lodicules. All enlarged.
