These numbers of the flowering times do not seem to be in favour 

 of the statement that the plants with bulbs, etc., fellow the fame laws 

 with regard to the flowering season as are observed by the weec'y 

 plants. The table just given show-j, v. g., the maximum of flowering 

 timas in August, in the same month in which the heibacecus plants 

 generally reach their maximum. In Darjeel'ng, too, the rainy season 

 develops more flowers than the comparatively dry part of the year. 



Just now I found mentioned in a book, that the flowering period of 

 the individual plant is much longer in the tropics than in the temperate 

 zones. In order to see how far that statement was reliable, I put to- 

 gether the flowering times of 100 herbaceous plants of Germany, be- 

 longing to the Papilionacese, and compared them with the flowering 

 times of 80 herbaceous plants of the same order, growing in the Bern- 

 bay Presidency. The total of the flowering times in Germany was 263 

 months, in Bombay 179. The mean flowering time for one plant is, 

 therefore, 2*6 months in Germany and 2*2 months in the Bombay Presi- 

 dency. Similar relations I detected in the herbaceous plants of the 

 orders RanunculaceEe, Malvaceae, and Umbelliferse, the mean flower- 

 ing times of which are : —
