of the grains and in more than 99 per cent of the total 

 starch in 3 minutes. 



The reaction with uranium nitrate begins in 15 sec- 

 onds. Complete gelatinization occurs in about 77 per 

 cent of the entire number of grains and 93 per cent of 

 the total starch in 1 minute, and in 100 per cent of the 

 grains and total starch in 3 minutes. 



The reaction with strontium nitrate begins imme- 

 diately. Complete gelatinization occurs in about 85 per 

 cent of the entire number of grains and 95 per cent of the 

 total starch in 1 minute, and in 100 per cent of the 

 grains and total starch in 2 minutes. 



The reaction with cobalt nitrate begins immediately. 

 Complete gelatinization occurs in about 73 per cent 

 of the entire number of grains and 95 per cent of the 

 total starch in 1 minute, and in about 95 per cent of 

 the grains and in more than 99 per cent of the total 

 starch in 3 minutes. 



The hilum is distinct in all the grains, accompanied 

 by the formation of a bubble in many more than in L. 

 martagon album. The lamella? are not so distinct as in 

 L. martagon album. Gelatinization begins at the hilum, 

 which swells even more rapidly than in L. martagon 

 album, unaccompanied by invagination of the proximal 

 end. Two short fissures extend obliquely from either side 

 toward the distal margin, and the material comprehended 

 between them is divided by longitudinal and oblique 

 fissures which are not so distinct or so long as in L. 

 martagon album. As the grain swells it is quickly trans- 

 formed into an irregularly granular mass, of which 

 the granules are not so distinct or so refractive as in 

 L. martagon album, and this is pushed to the distal 

 margin where it is sometimes divided by wedge-shaped 

 fissures into a serrated border, but not so frequently as in 

 L. martagon album. In the other grains it forms merely 

 an irregular granular mass at the distal margin that 

 is sometimes entirely gelatinized before the material 

 at the proximal end and sides. This, as the grain swells, 

 forms a homogeneous-looking, refractive band which 

 shows no lamellar markings as in L. martagon album. 

 The gelatinized grains are as much swollen, have thinner 

 capsules, and are usually not so much distorted at the 

 distal end as in L. martagon album. 



The reaction with copper nitrate begins immediately. 

 Complete gelatinization occurs in about 97 per cent of 

 the entire number of grains and 99 per cent of the total 

 starch in 1 minute, and in 100 per cent of the grains 

 and total starch in 2 minutes. 



The reaction witli cupric chloride begins immediately. 

 Complete gelatinization occurs in about 84 per cent of 

 the entire number of grains and 98 per cent of the total 

 starch in 1 minute, and in 100 per cent of the grains and 

 total starch in 3 minutes. 



The hilum becomes distinct in all the grains, attended 

 by the formation of a bubble in a moderate minority of 

 the grains, instead of a majority as in L. martagon 

 album. The lamella? are somewhat more distinct than 

 in L. martagon album. Gelatinization begins at the 

 hilum, which swells more rapidly toward the proximal 

 than the distal end. As the hilum and the grain en- 

 large there is a deep invagination of the proximal end 

 which is later pushed out again. This feature is not seen 

 in L. martagon album. Two fissures extend from the 

 hilum one half to three-fourths of the distance from 



the hilum to the distal margin. The starch compre- 

 hended between them is more indistinctly fissured than 

 in L. martagon album and is rapidly gelatinized, leaving 

 a much smaller granular residue at the distal end than in 

 L. martagon album. This is gelatinized before the 

 deposit at the margin. The starch at the proximal 

 and distal margin and sides, as in L. martagon album, 

 forms a homogeneous-looking, refractive band which 

 gradually grows thinner ami more nearly transparent 

 until it is completely gelatinized and only the capsule 

 remains. The gelatinized grains are as much swollen as 

 in L. martagon album. They have less thick capsules, 

 and are more distorted at the distal end, than in L. mar- 

 tagon album. 



The reaction of barium chloride begins immediately. 

 Complete gelatinization occurs in about 68 per cent of the 

 entire number of grains and 89 per cent of the total 

 starch in 1 minute; in about 89 per cent of the grains 

 and 97 per cent of the total starch in 3 minutes; and in 

 about 95 per cent of the grains and in more than 99 per 

 cent of the total starch in 5 minutes. (Chart D 353.) 



The reaction with mercuric chloride begins immedi- 

 ately. Complete gelatinization occurs in about 83 per 

 cent of the entire number of grains and 97 per cent 

 of the total starch in 30 seconds; and in about 9G per 

 cent of the grains and in more than 99 per cent of the 

 total starch in 1 minute.

Histologic Properties. 



In form the grains are usually simple and isolated. 

 Compound grains are as rare as in L. maculatum, and 

 are of the type described under both parents. The 

 grains are more often irregular than in either parent, in 

 this respect more closely resembling L. maculatum, and 

 the irregularities are due to the same causes, secondary 

 sets of lamella? being more common than in that starch. 

 The conspicuous forms are broad and narrow pyriform, 

 broad and narrow triangular with curved base and 

 rounded angles, elongated ovoid with squared or rounded 

 distal end, and clam-shell-shaped. The additional forms 

 are club-shaped, finger-shaped, nearly round, oyster-shell- 

 shaped, and dome-shaped. As in both parents, the broad 

 forms are somewhat flattened, and when viewed on edge 

 have an elongated ovoid shape. 



In form L. marhan shows a closer relationship to L. 

 maculatum than to L. martagon album. 



The hilum is as distinct as in L. martagon album and 

 less distinct than in L. maculatum, and is more often 

 fissured or occupied by a cavity than in either parent, 

 in the first characteristic more closely resembling L. 

 maculatum and in the second L. martagon album. The 

 fissures have the same form as in L. martagon album. 

 The hilum is eccentric from 0.32 to 0.1, usually 0.2, of 

 the longitudinal axis, slightly more than in L. martagon 

 album, but less than in L. maculatum. 



In the character and eccentricity of the hilum L. 

 marhan shows, on the whole, a closer relationship to L. 

 martagon album than to L. maculatum. 



The lamella? are as distinct and as fine as in L. mar- 

 tagon album, and have otherwise the same characteristics 

 and arrangement as in both parents. The number
