1. A. Calamagrostis {small Reed), panicle erect diffuse, cal. 

 valves acuminate, cor. shorter than the cal. and the tuft of 

 hairs with a small terminal awn. Light/, p. \Ofy. E. B.t.2\59. 



Hab. Shady moist places, but not common, Lightf. Fl. Jv.ly. 7/. 



Two or three feet or more high. Leaves linear, acuminate. Cal. gla- 

 brous shining, purple brown. Cor. very thin and membranous. 

 Tuft of hairs silky, very apparent from their length, and giving the 

 panicle, when in full blossom, a beautiful silky appearance. 



2. A. stricta {smallest close Reed), panicle erect close, valves 

 of the cal. acute, cor. about as long as the cal. longer th.Tn the 

 tuft of hairs, with a dorsal awn equal to it in length. E. B.

H.vB. White Mire Marsh, 1 mile from Forfar, G. Don. Fl. June. 1/ . 



One to two feet high. Leaves narrow, linear, when dry involute. Pani- 

 cle I — 4 inches long. CV/L brown, glabrous. Cor. brownish, truncate. 

 Hairs few, short, vLsible on dissection. 



it Corolla aimless. 



3. A. arenaria {Sea-side Reed), panicle spiked, valves of thecal. 

 acute, cor. as long as the cal. thrice as long as the tuft of hairs, 

 leaves involute pungent. Light/', p. 107. E. B. t. 520. 



Hab. Sandy places on the sea-shore. Cantyre, between Mackreanish 

 Bay and Barr, and near Aberbrothick in Angus, Lighff. Common 

 in Orkney, Mr. Neill. U . 



Two or three feet high, glaucous. Root much creeping. Leaves very 

 long and acuminate. Panicle in a very compact spike, attenuated 

 at each extremity. Cal. rough at the keel, submembranous. Cor. far 

 more rigid, awnless, nerved. Anthers large, purple. Called Muran 

 in Gaelic (Light/.), in Norfolk Marram. \'ery serviceable in bind-

4. A. Phragmites {common Reed)., cal. about o-flowered, florets 

 longer than the cal. Lii^htf. p. 106. E. B. t. 401. 



Hab. Abundant in ditches, margins of lakes, rivers. Sec. Fl. July. U . 



Six feet or more high. Leaves broad, lanceolate, much attenuated. 

 Panicle large, purple-brown, at length drooping, ver\- handsome. 

 Valves of the cal. very unequal ; e.xt. ovato-lanceolate ; int. twice 

 its length, thin, membranous. At the ba.se of each floret is a very 



creeping stolons, .^^g-ros^'* s^o/o«(/era cf mo.st English authors, I have no 

 doubt, is only a var. (if as much) of A. alba. Dr. Richardsons famous Fioriii 

 is certainly so ; but whether such a plant exists in England as A. stolonif. 

 Linn., with the cal. and panicle still more hispid than alba, I cannot deter- 

 mine. I am inclined to think, tliat our A. stolonif. is only the extreme of 

 alba in harshness, and consequently hispidness, arising from the richness ot 

 the soil."
