182 HORTUS GRAMINEUS WOBURNENS1S. 



POA nemoralis, var. angustifolia. Wood Meadow-grass. Germ. 

 Hain Rispengras. 



Specific character: panicle capillary, flowering a little on one 

 side, diffuse ; spikelets lanceolate, mostly 3-flowered ; florets 

 hairy at the base, without a web. See Smith Engl. Fl. i. 

 p. 129. Var. angustifolia, leaves long, slender, husks from 

 three to five-flowered. 



Obs. The sheath-scale is very short, and truncated ; straw 

 rather compressed than otherwise, vagina smooth, root stolo- 

 niferous. Hardly any grass varies more than the Poa nemo- 

 ralis var. in the number of florets contained in the calyx. 

 When the Poa nemoralis var. angustifolia is raised from seed, 

 in open situations, the first year, the calyx contains only from 

 3 to 5 florets ; afterwards, the number increases to 9 florets 

 in each calyx : when raised from seed in shady situations, it 

 has frequently only 2 florets in each calyx, and sometimes 

 only 1, the first year : the number does not increase afterwards 

 to more than 3 florets in each calyx. In its natural place of 

 growth, Poa nemoj'alis, in woods under the shade of trees, con- 

 tains only three florets, and, when long cultivated in exposed 

 situations, the calyx is 4 and 5-flowered. The next following 

 grass, though a distinct species, resembles this in several of its 

 agricultural merits. E. Bot. 1265. Host. t. 71. Flo* Dan. 

 t. 749. Flo. Ger. 301. The Poa concinna, Poa debilis, and 

 Poa variegata of Schleicher, are all nearly allied to Poa ne- 

 moralis angustifolia. Root fibrous and stoloniferous^.

* The Poa concinna, Pua debilis, and Poa variegata of Schleicher are all nearly 

 allied to the Poa nemoralis angustifolia. The Poa variegata of Schleicher is de- 

 scribed as having a creeping root; Roemer and Schultes follow Schraderin describ- 

 ing it under the name of Poa si/pina; the former quote Host. Gram. Austr. iv. t. 27 : 

 but the plant under cultivation has arrows root; numerous shoots are formed at 

 the bottom of the culms during the season of growth, and at the joints of the culms 

 shoots or branches are emitted, particularly in moist seasons ; all this is precisely 

 the habit of the Poa nemoralis and its varieties. The plant may be said to have 

 an upright stoloniferous stem, and a fibrous stoloniferous root, to distinguish it from 

 the possession of the stoloniferous stem and the creeping root, properly so called. 

 The plants of Poa variegata here spoken of, and cultivated in the Woburn Abbey 

 Experimental Grass Garden, were communicated to the Duke of Bedford by my 

 friend Mr. Anderson, of the Botanic Garden, Chelsea.
