9£ inches, and each bears on an average 122 seeds. Before maturity 

 the glumes and the distal end of the spikelets are purplish brown. 

 The stigmas are tinged with purple. 



The seeds (PI. II, A and B) average 8.9 millimeters in length and 

 2.9 millimeters in thickness. The glumes are light brown and plainly 

 notched on the margins. The thin hull, which loosely incloses the 

 kernel, is light brown and sparingly covered with short white hairs, 

 which are more numerous toward the apex. The apex of the hull 

 terminates in two conical dark-brown teeth, located on the meson, 

 which are unequal in length and slightly bent ventrad. The conical 

 lateral teeth usually are absent and when present are very incon- 

 spicuous. 



The kernels (PI. II, C and D) average in length 7.1 millimeters, 

 in width 1.6 millimeters, and in thickness 2.4 millimeters. Viewed 

 laterally, the dorsal and ventral margins are unequally convex, the 

 ventral being the less so. Their distal end is more or less obtuse. 

 The opaque area is seldom present. 



This variety matures in approximately 131 days and produces an 

 average yield of 1,862 pounds of paddy and 1,350 pounds of straw per 

 acre. Although its yielding capacity is not large, this rice is worthy 

 of cultivation on account of the distinct flavor of its kernels, resem- 

 bling that of pop corn. This character is not possessed by any other 

 rice except Salvo grown in the United States. 



TOKALON. 



The Tokalon variety is a pure-line selection from the Carangiang 

 variety, which was obtained in 1904 by the United States Department 

 of Agriculture from the rice exhibit of the Philippine Islands at the 

 Louisiana Purchase Exposition. 



The selection was made at the Rice Experiment Station, Crowley, 

 La., by the writers in 1911. The name Tokalon is derived from the 

 Greek, meaning the beautiful, and Avas applied to this variety in 

 1917. The selection was increased from nursery to plat experiments 

 in 1915. The plat yields are given in Table 2. The variety was dis- 

 tributed in southwestern Louisiana for commercial growing in 1918. 

 Enough seed of Tokalon (C. I. No. 51) was grown in 1921 to sow 

 6,000 acres in 1922. 



The thick culms of the Tokalon variety are green and usually num- 

 ber six to the plant. Their average height, including the panicles, 

 is 50 inches. The culm nodes are brown; the sheath nodes green. 

 The inner surface of the leaf sheaths is light purple. The auricles 

 are deciduous. The ligules average five-eighths of an inch in length. 

 The leaf blades are broad, measuring five-eighths of an inch in width. 

 The panicles have an average length of 10J- inches, and each bears on 

 an average 152 seeds. Before maturity the distal end of the spike- 

 lets is reddish brown. 



The seeds (PI. II, E and F) average 9.3 millimeters in length 

 and 2.9 millimeters in thickness. The glumes are pale yellow and 

 have smooth margins. The hull firmly incloses the kernel. It is 

 light yellow, medium in thickness, and thinly covered with short 

 white hairs. The apex of the hull terminates in four conical brown 

 teeth. The two located on the meson are prominent, unequal in 

 length, and bent ventrad. The other two are lateral and verv short.
