was increased from nursery to plat experiments in L915. The plat 

 yields are given in Table 2. The variety was distributed in south- 

 western Louisiana for commercial growing in 1918. Enough seed 

 of Fortuna (C. I. No. 1344) was grown in 1921 to sow approximately 

 L00,000 acres in 1922. 



The stout green culms of the Fortuna variety are striped with 

 purple and usually number five to the plant. Their average height, 

 including the panicles, is 51 inches. The nodes are brown, marked on 

 their lower margin with green. The sheath nodes are light green 

 and marked on tneir upper margin with purple. The outer surface 

 of the leaf sheaths is green, streaked with purple, and their inner 

 surface is purple, especiallv toward the base. The auricles are mem- 

 branous and persistent. The ligules average five-eighths of an inch 

 in length. The leaf blades are broad, averaging five-eighths of an 

 inch in width. The panicles have an average length of 11-J inches, 

 and each bears on an average 187 seeds. Before maturity the glumes 

 are dark purplish brown, and the distal end of the spikelets is 

 purple. The stigmas are dark purple. 



The seeds (kernel plus hull; PI. I, D and E) average 10.1 milli- 

 meters in length and 3.1 millimeters in thickness. The glumes are 

 light brown and distinctly notched on the margins. The hull (lemma 

 and palea) is pale yellow, medium in thickness, and thinly covered 

 with short white hairs. The apex of the hull terminates in two 

 dark-brown conical teeth, located on the meson, and unequal in 

 length. The conical lateral teeth usually are absent and when pres- 

 ent are inconspicuous. 



The kernels (PI. I. F and G) average in length 7.7 millimeters, 

 in width (lateral diameter) 1.8 millimeters, and in thickness (dorsi- 

 ventral diameter) 2.5 millimeters. Viewed laterally, the dorsal and 

 ventral margins are unequally convex, the ventral being the less so. 

 The distal end is obtuse. The opaque area when present is narrow 

 and located near the center of the kernel. 



This variety matures in approximately 142 days and has produced 

 an average yield of 2.530 pounds of paddy and 2,210 pounds of straw 

 per acre. On the lighter soil of southwestern Louisiana it produced 

 2.109 pounds of paddy per acre. Acre yields of 2,775 pounds of 

 paddy have been obtained from it on old prairie land which had been 

 rested and closely pastured for two years. On new land in the 

 Mississippi River section of Louisiana near Carville this variety has 

 produced 5.366 pounds of excellent grain per acre. It produces good 

 yields on poor soil. When grown on very rich soil it shows a 

 tendency to lodge. Tts grain is likely to shatter if harvest is de- 

 layed too long after maturity. 



ACADIA. 



The Acadia variety is a pure-line selection from the Omachi 

 variety, which was imported from Japan in 1910 by a rice farmer 

 of ( Irowley, La. 



This selection was made at the Rice Experiment Station, Crowley. 

 La., by the writers in 1911. The name Acadia is the name of the 

 parish in which the station is located and was applied to this selection 

 in 1917. The selection was increased from nursery to plat experi- 

 ments in 1916. The plat yields are given in Table 2. The variety
