follicles, the average number and weight of the seeds in each follicle is greater than in 

 the 337 unselected follicles. 



A few of the scraped follicles in my possession, obtained from Mr Buchanan in 1885, 

 are, however, of greater length than any of those represented in Tables III. and IV. 

 Their form, also, is nearly cylindrical ; but, while the seeds contained in them have the 

 same characters as those in the fusiform and lanceolate follicles, these seeds are of relatively 

 light weight, and, apparently, insufficiently ripened. Several of the follicles are from 

 15 to 17 inches in length, but one of 17 inches weighed only 165 grains, and one of 

 15 inches only 146 grains. In a follicle 15 inches long, the diameter at the base is 

 075 inch, at the middle 0"65, and at the apex 0"59 ; and in another, also 15 inches long, 

 the respective diameters are 0'59, 0*62, and 0'53 inch. 



The average number of seeds in each follicle of the 337 represented in Table III. is 

 180*8, and the average weight of the seeds in each follicle is 69 "4 grains. In the twenty 

 follicles of average size and weight represented in Table V. , the average number of seeds 

 in each follicle is 197% and the average weight of the seeds in each follicle is 90*5 grains. 



These averages are, however, much above and below the numbers and weights actually 

 found in many follicles. This is illustrated by the following examples : —
