Awns of lemma lobes about 2 mm. long__---------------_- 2. D. domingensis. 
1. Danthonia shrevei Britton; Nash, Torreya 9: 210. 1909. 
A densely tufted perennial with elongate involute scabrous blades aggregated 
at the base and overtopping the rather open panicle, the spikelets 12 to 15 
mm. long, the spreading awns about 1 cm. long. 
On cleared slopes near summit of Sir Johns Peak, Jamaica, whence described 
and the only known locality, the type collected by Shreve, May 7, 1906. 
Grows in large dense tufts that finally form tussocks raised above the general 
level of the soil. 
2. Danthonia domingensis Hack. & Pilger in Urban, Symb. Antill. 6: 1. 1909. 
Resembling the preceding, the blades more slender, scabrous only toward the 
apex, the panicle looser, the spikelets slightly larger. 
Mountain meadows, Santo Domingo, whence described (Loma Rosilla, 
Province de la Vega, Fuertes 1776; Constanza, Tiirckheim 3414), The type 
specimen is Eggers 2227b. 
76. CAPRIOLA Adans. 
Spikelets 1-flowered, sessile, imbricate, in slender unilateral spikes; glumes 
unequal, narrow, acute; lemma broad, boat-shaped, inclosing a palea of equal 
length. 
1, Capriola dactylon (L.) Kuntze, Rev. Gen. Pl. 2: 764. 1891. BERMUDA GRASS. 
Panicum dactylon L. Sp. Pl. 58. 1753. 
Cynodon dactylon Pers. Syn. Pl. 1: 85. 1805. 
A low, extensively creeping perennial with compressed wiry culms, narrow, 
usually short blades, and 3 to 5 slender arcuate-spreading spikes aggregated 
at the apex of the culms. 
Common in open, rather dry ground in the warmer parts of both hemispheres ; 
apparently introduced in America. Originally described from southern Eu- 
rope. To be found on probably all the islands of the West Indies. A common 
and well-known pasture grass, called Bermuda grass in the United States and 
Bahama grass in the English West Indies. In the Spanish islands it is called 
“grama,” “hierba fina,” and “hierba del prado,” and because of its digitate 
spikes, ‘“ pata de gallina.” In Antigua it is called “ devil’s grass.” 
77%. SPARTINA Schreb. 
Spikelets 1-flowered, sessile, flattened laterally, densely pectinate in thick 
unilateral spikes; glumes unequal, acuminate; lemma and palea obtuse, sub- 
equal. 
1. Spartina patens juncea (Michx.) Hitchc. Rhodora 8: 210. 1906. 
Trachynotia juncea Michx. Fl. Bor. Amer. 1: 64. 1803. 
Spartina juncea Willd. Enum. PI. 81. 1809. 
Perennial with long stout scaly rhizomes and slender but strong erect culms 
commonly 1 meter or more tall, the long blades firm, involute, the inflorescence 
of 3 to 6 suberect spikes about 5 cm. long. Large colonies of sterile plants 
often found on sandy beaches.
