362 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Wet ground, southern United States to Uruguay and Peru, whence originally 
described. Grisebach* records this species from Trinidad, but to us it is known 
from the West Indies only from Cuba (Lagoon Haiti, Mordazo, Leén 5941). 
2. Luziola bahiensis (Steud.) Hitchce. Contr. U. S. Nat. Herb. 12: 234. 1909. 
Caryochloa bahiensis Steud. Syn. Pl. Glum. 1: 5. 1854. 
Tuziola alabamensis Chapm. Fl. South. U. S. 584. 1860. 
Luziola longivalvula Doell in Mart. Fl. Bras, 27: 17. 1871. 
A slender glabrous stoloniferous aquatic perennial with long linear blades (or 
aerial blades shorter and 4 to 5.mm. wide), narrow staminate panicles termi- 
nating the main culm, and open few-flowered pistillate panicles terminating the 
branches. Extremely variable in appearance according to the depth of water 
in which the specimen grew. Plants growing in places from which water has 
receded are low and widely creeping. 
Rivulets, Alabama to Brazil. Originally described from Bahia. 
Also in Cuba (Pinar del Rio, Wright 3813). 
3. Luziola spruceana Benth.; Doell in Mart. Fl. Bras. 27: 18. 1871. 
Culms thick, soft and spongy, freely branching; sheaths broad with long 
erect auricles; staminate panicles terminal; pistillate panicles terminal and 
axillary, corymbose, the numerous branches reflexed at maturity. 
Ponds and lagoons, Cuba to Brazil, whence originally described. Called 
“ pond-grass ” in Trinidad. 
Cuba (Ariguanabo Lagoon, Ledén 4193), Trinidad (probably near Caroni River, 
Broadway 1626), and Tobago (The Whim, Broadway 3100). 
58. ORYZA L. 
Spikelets perfect, paniculate, laterally compressed; glumes minute; lemma 
and palea subindurate, papillose-roughened, the lemma awned (the awn some- 
times obsolete). 
1. Oryza latifolia Desv. Journ. de Bot. Desv. 1: 77. 1813. 
Oryza sativa var. latifolia Doell in Mart. Fl, Bras, 2°: 7. 1871. 
A rather robust perennial, the simple culms 2 meters or more tall, with thin 
flat scabrous blades commonly 50 to 60 em. long and 4 to 5 em, wide, and large 
many-flowered panicles, the short-awned spikelets short-pediceled along the 
upper half to two-thirds of the long slender ascending branches. 
Swamps and ditches, Central America and West Indies to Brazil. Type 
locality given as Carolina and Porto Rico, the first clearly an error. The awn 
is described by Desvaux as being “ brevissima.” Later Hamiiton® described the 
species from a specimen in Desvaux’s herbarium without mentioning the awn. 
The habitat is here given as “in parte Hispanica Hispaniolae.” 
Haiti (Bayeux), Porto Rico (Mayaguez), and Trinidad (St. Joseph, Cedros). 
Oryza SATIVA L. Sp. Pl. 333. 1753. Curtrivarep rick. ARRoz. This plant is 
cultivated throughout the West Indies and is occasionally found growing 
spontaneously in fields and ditches. 
59. HOMALOCENCHRUS Mieg. 
Spikelets awnless, the glumes wanting, otherwise as in Oryza, the plants 
and spikelets much smaller.
