19. PHALARIS L. CANARY GRASS 



Spikelets 1-flowered, laterally flattened ; glumes equal, boat-shaped, much 

 exceeding the florets ; sterile lemmas small and narrow, appearing like hairy 

 scales attached to the fertile floret ; fertile lemma indurated and shining in fruit, 

 inclosing a faintly 2-nerved palea. Annuals or perennials, with flat leaves and 

 dense spike-like panicles. (The ancient Greek name, 0a\a/>fc, alluding presuma- 

 bly to the crest-like inflorescence.) 



1. EUPHALAB1S Godron. Panicle very dense, spike-like; glumes 

 wing-keeled. 



1. P. CANARIENSIS L. (CANARY GRASS.) Annual, 3-8 dm. high ; panicle 

 oval, 2-3 cm. long ; spikelets broadly obovate, 5-6 mm. long, imbricated ; glumes 

 white with green veins, the keel entire ; fertile lemma brown. 



Waste places and roadsides. (Adv. from Eu.) 



P. MINOR Retz. has been collected at St. John, N. B. (Fowler) 

 and on ballast at Camden, N. J. (Pollard). The spikes are 

 oblong and the glumes are narrowed at the pointed apex, the 

 exposed portion of the keel being somewhat toothed. 

 2. DfGR APHIS (Trin.) Endl. Panicle branched, the clusters 

 open in anthesis ; glumes not winged on the back. 



2. P. arundinacea L. (REED C.) Perennial, 6-15 dm. 

 high ; leaves flat, 6-10 mm. wide ; panicle 6-15 dm. long ; 



spikelets lanceolate, 5 mm. long, pale ; sterile lemmas reduced 76 . P . arundinacea 



to minute hairy scales. Wet grounds; common, especially 



north w. June, July. FIG. 76. Var. pfcTA L., the leaves 



striped with white, is the familiar RIBBON GRASS of the garden. 



(Eurasia.) 



20. ANTHOXANTHUM L. SWEET VERNAL GRASS 



Spikelets 1-flowered ; glumes very unequal ; sterile lemmas 2-lobed, hairy, 

 dorsally awned, longer than the fertile floret and falling with it ; fertile lemma 

 truncate, awnless, inclosing a faintly 1-nerved palea and per- 

 fect flower ; stamens 2. Aromatic plants with flat leaves 

 and narrow spike-like panicles. (Name compounded of 

 &v9os, flower, and J-avd6s, yellow.) 



1. A. ODORATUM L. Perennial; culms slender, erect, 

 2-6 dm. high; leaves rough above; panicles 3-8 cm. long; 

 spikelets brownish green, 8-10 mm. long, spreading at flower- 

 ing time; glumes sparsely pilose ; first sterile lemma short- 

 awned below the apex, second bearing a strong bent scarcely 

 exserted awn near its base. Meadows, pastures, and waste 

 places, throughout, especially eastw. May-July. Sweet- 

 scented. (Nat. from Eu.) FIG. 77. 



2. A. PUELII Lecoq & Lamotte. Smaller, annual; pani- 

 77. A. odoratum. cles I- 4 cm - lon S 5 spikelets whitish green, 5-7 mm. long ; 



Inflorescence x %. ^ e glabrous glumes narrower than in no. 1 ; the long-exserted 



Spikeiet; same 2 \vith awn blackish at base. Dry fields and waste places, N. E. 



glumes separated to Ont. and Pa. ; sometimes cultivated westw. and southw.

Spikeiet ; same 

 with glumes sep- 

 arated. 



21. HIER6CHLOE [Gmel.] R. Br. HOLY GRASS 



Spikelets 3-flowered, the terminal flower perfect, the others staminate or 

 empty ; glumes subequal, about the length of the spikelet, boat-shaped, shining ; 

 sterile lemmas nearly as long as the glumes, boat-shaped, indurated and hairy, 

 each inclosing a 2-nerved hyaline palea and a flower of 3 stamens ; fertile lemma 

 similar but smaller, inclosing a 1-nerved palea and perfect flower with 2 stamens.
