SEEDLINGS OF LUPINUS TIDESTROMII 



By a. a. Hkli.kr 



A most interesting study diirinj^ the past three months has 

 been the development of seedlings of various species of lupines, 

 the seeds of which were planted January 20th. Among them 

 were a few of L. Tidcstromii^ for which I am indebted to Pro- 

 fessor C. P. Smith. They were collected in June, 1908, and 

 were so slovv to germinate that I had about given up hope of 

 obtaining any plants. But during the latter part of February 

 the cotyledons of three plants appeared. The plants presented 

 a peculiar appearance from the first. The cotyledons of most 

 perennials are 10 to 15 mm. long, 7 to 10 mm. wide, and have 

 fairly long petioles. These were smaller than the average, only 

 about 7 mm. long, 4 mm. wide, very short petioled, and were 

 closer to the orround than usual.

 The plants are not rapid growers. The first photograph 

 (figure 9, left hand plant) was taken March 29th, and shows the 

 plant natural size at that time.
