2. B. pubescens Muhl. ex Willd. (figure 2) Canada Brome 



Perennial. Rich or rocky woods. Southeastern N.H.; rare. 

 B. purgans of Gray's Manual (see Wagnon, 1950 for nomenclatural 

 change). 



3. B. ciliatus L. Fringed Brome 



Perennial. Tickets, open woods and roadsides. Common 

 throughout the state. Very variable in pubescence. Fernald (1950) 

 recognized two varieties, var. ciliatus and var. intonsus; however there is 

 considerable integradation between the two morphological extremes. 

 We follow Wagnon's (1952) treatment and do not recognize in- 

 fraspecific taxa. B. Dudleyi Fern, is also included in the species. 



4. B. kalmii A. Gray (figure 5) Brome Grass 



Perennial. Alluvial banks of large rivers, Connecticut and 

 Merrimack River Valleys. Rare. 



Baum (1967) notes that the name B. purgans should be applied to 

 this taxon rather than to B. latiglumis or B. pubescens. But Voss (1972) 

 has rejected the name as a nomen confusum and it has been formally 

 proposed for rejection under Article 69 by McNeill (1976). 



5. B. inermis Leyss. (figure 3) Smooth Brome 



Rhizomatous perennial. Important forage grass, commonly planted 



in hayfields and frequently escaping. Throughout the state. Introduced 



from Europe and Siberia. 



The following introduced annuals occur occasionally in gardens and 

 waste places in the state and may not persist: 



B. secalinus L., B. japonicus Thunb., B. racemosus L., B. mollis L. and 

 B. tectorum L. (figure 4) 



2. SCHIZACHNE False Melic 



Large native grass; cespitose, stems erect, unbranched; spikelets large; 

 lemmas with prominent awns from below the bifid apex. 



Gould (1968) places the genus in the Tribe Meliceae. 

 1. Scbizacbue purpurascens (Torr.) Swallen (figures 6 and 7) 



Cespitose perennial. Spikelets flushed with purplish color. Dry or 



rocky woods and ledges, ascending to alpine areas. Frequent in 



northern part of the state, rare southward. 



3. FESTUCA Fescue 



A rather large genus somewhat resembling Bromus but with plants 

 tufted and inflorescences erect; lemmas often with prominent straight awns. 



Some members of the genus, such as F. ovina, F. capillata and F. rubra, 

 were formerly planted in hayfields where they persist. Some cultivars are 

 used in lawn mixtures and frequently spread. 



A. Spikelets with florets replaced by vegetative tufts (viviparous). 



Alpine F- prolifera 



A. Spikelets with normal florets 

 B. Blades flat, 4-8 mm wide 



C. Panicles diffuse; spikelets 3-7 mm long, 3-6-flowered 



F. obtiisa
