14. ARUNDO. 



* Calyces I -flowered (Calamagrostis of authors), 

 f Corolla awned. 



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. Lightf. p. 1 Ofi. E. B. t. 2159. 



HAB. Shady moist places, but not common, Lightf. Fl. July. If. . 



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. strict a (smallest close Reed), panicle erect close, valves 

 of the cal. acute, cor. about as long as the cal. longer than the 

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

 t. 21 GO. 



HAB. White Mire Marsh, 1 mile from Forfar, G. Don. Fl. June. I/.. 



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

 cle I 4 inches long. Cal. brown, glabrous. Cor. brownish, truncate. 

 Huirs few, short, visible on dissection. 



ft Corolla awnless. 



3. A. arenarla (Sea-side Reed), panicle spiked, valves of the cul. 

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

 leaves involute pungent. Lightf. p. 107 . .. B. t. 520. 



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

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

 in Orkney, Mr. Neill. H . 



Two or three feet high, glaucous. Root much creeping. Leave$ 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 (Lightf.), in Norfolk Marram. Very serviceable in bind- 

 ing the loose sands by the sea-shore. 



** Calyces many -flowered (Arundo of authors). 



4. A. Phragmites (common Reed), cal. about 5 -flowered, florets 

 longer than the cal. Lightf. p. 106. E. B. t.40\. 



HAB. Abundant in ditches, margins of lakes, rivers, &c. Fl. July. )/ . 



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

 Panicle large, purple-brown, at length drooping, very handsome. 

 J'alves of the cal. very unequal; ext. ovato-lanceolate 5 int. twice 

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



creeping stolons. Agrostis stolonif era cf most English authors, I have no 

 doubt, is only a var. (if as much) of A. alba. Dr. Richardson's famous Florin 

 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, that our A. stolonif. is only the extreme of 

 alba in harshness, and consequently hispidncss, arising from the richness of 

 the soil."
