and 21 which are either abortive or injured. The number 

 of abortive clusters might be somewhat increased if great 

 care had been exercised in looking for the accessory buds just 

 above the axils of the lowest leaves on the branches. As a rule, 

 however, the first internode or so, if questionable, was omitted. 

 From this it would seem that about eight per cent, of the clus- 

 ters fail to develop, a percentage which would probably be 

 somewhat increased if care had been exercised in noting the 

 buds where development had been arrested at a very early stage. 



On the 10 plants, 14 axillary clusters were produced, being 

 5.5 per cent, of all the developed clusters. Of these 14 clusters, 

 2 produced 2 buds each, the others only 1 ; an average of 1.14 

 flowers per cluster. The 241 normally developed clusters pro- 

 duced 773 buds, an average of 3.27 flowers per cluster. Of the 

 773 buds produced on the 10 plants, 22 are found to be injured 

 and fail to develop normally ; a percentage of 2.84. 



While the series of material is too limited to permit of in- 

 dulging in generalizations, it might be of interest to note that on 

 40 plants bearing 332 seed pods, taken from two square feet 

 of ground, September 4, and 3 other plants producing 130 

 seed pods, taken at the same time, not a single pod developed 

 from an axillary cluster was found. These plants, "however, 

 with the exception of the last three, represent all produced on a 

 definite area. It might not be improbable that the smaller, 

 crowded plants would not be so likely to produce axillary clus- 

 ters as the larger plants growing under more favorable condi- 

 tions. We may at least conclude from this that the axillary 

 flowers are of little consequence in the seed-producing capacity 

 of the plant. 



For the sake of convenience, it has been deemed advisable to 

 summarize in table E the conditions of the liowers and buds 

 which will probably open the day following, as given in table 

 D. From this table, it will be seen that on the day the plants 

 were examined 42 flowers were open — 5.4 per cent, of the 

 773 buds produced on the 10 plants. These flowers as well as 

 the buds, 36 in number, which were to open the next day, 

 are equally divided into right- and left-handed. 



The buds which are next to open do not, in any of the cases 

 noted in the above tables, occur on a cluster with Mowers which 

 are already open.
