place of the blue. Why the blue pigment was absent in the 

 partially albino flowers while the lavender-pink pigment was 

 present, is, of course, another question, and one that I did not 

 investigate. However, I tagged and gathered seed from several 

 plants of each color type and later planted the seeds, hoping to 

 find out whether the pigment characters would breed true; but 

 disappointment awaited me, as none of the seeds germinated, 

 even tho three different plantings were made. 



The seeds are pale flesh-colored, almost unmarked in the 

 case of the pink flowered plants, but plainly marked with a 

 marbling of yellowish-brown in the normal colored plants — by 

 far the palest colored lupine seeds I have collected in California. 

 My numbers ij.02 and 1403 are of the pink and blue flowered 

 forms respectively, collected 13 April, 1908, Stanford University 

 estate, San Mateo county side of the stream mentioned above. 



This species is evidently one of the forms that commonly 

 pass as L. micranthus in California; but such a determination 

 can not hold, as proved to me by a careful study of a recent col- 

 lection, Mr. Heller's no. 10100, from along the Columbia, in 

 Oregon, probably very close to where Douglas secured his L. 

 micranthus. I have very recently compared a specimen of that 

 collection with the original description and plate of L. micran- 

 thus (Lindl. Bot. Reg. 15:/>/. 1251. 1829) a "d my conviction is 

 firm that Mr. Heller has secured the true micranthus, and that 

 few or none of the plants from middle and southern California 

 called A. micranthus are properly so determined. The nearest 

 affinity of true micranthus^ and it seems to me a close one, is 

 with Greene's A. polycarpus, as I have already suggested in the 

 early part of this paper. 



I have found no description of an annual that will apply to 

 my nos. T4.02 and / /" ,\ hence believe that it is really unde- 

 scnbed, having been accepted as L. micranthus for years; but 

 'he limited distribution of my plant in a cultivated field, the 

 color oi the seeds, and also the fact that the species was found 

 nowhere else in my wanderings, all suggest to me that it may 

 have been introduced from elsewhere, probably from the great 

 interior valley, or from southern California, where, as I learn
