it had 4-angled buds. Class II was more diversified than 

 Class I, but this was probably because of its being repre- 

 sented in the culture by fourteen times as many plants. 



It is of interest to compare the hybrids of these two 

 classes with their parents. The plants of Class I resemble 

 the biennis parent in the red glands on ovaries and green 

 stems, inconspicuous collars, narrower leaves, and Wr- 

 angled buds; they resemble the grandiflora parent in 

 having longer stigma lobes, longer capsules and persist- 

 ent bracts. The plants of Class II resemble the grandi- 

 flora parent in the absence of the red coloration in the 

 glands on the ovaries and green portions of the stems, 

 and in having more conspicuous collars, broader leaves, 

 and round buds; they resemble the biennis parent in 

 having shorter stigma lobes, shorter capsules, and decid- 

 uous bracts. It will be noted that the contrasted char- 

 acters are mixed for both classes of plants, some of them 

 being biennis-like and some of them grandiflora-like. 

 Thus neither class could be claimed as patroclinous or 

 matroclinous except it were established that gland colora- 

 tion, size of collar, form of leaves and form of buds are 

 more important specific characters than length of stigma 

 lobes, length of capsule and the persistent or deciduous 

 nature of the bracts, or vice versa. Of these diverse 

 characters who would be willing to express the opinion 

 that one set or the other is not of consequence in a de- 

 scription of the forms? Yet it would be necessary to 

 disregard one or the other set of characters if either class 

 of hybrids were defined as patroclinous or matroclinous. 



We have stated before that the plants of the culture 

 were set in the ground with the few more biennis-like 

 rosettes at one end of the bed, and the few more grandi- 

 flora-like at the other end, and that these extreme forms 

 graded insensibly into the mass of the culture. It is 

 important to note that not one of the 12 plants of Class I 

 was at either end of the series, but they were scattered 

 irregularly through the culture, in some cases 2 or 3 close 

 together, but usually wide apart. I know as yet no way in
