 plant's energies would go to the development of the 

 seed, — nature's method of reproduction, — and the bulbs 

 produced would be small and with but few or no offsets. 

 From nature's standpoint the bulb is of consequence as 

 a means of reproduction or perpetuation of the species 

 only in case of failure of seed production.

By the cutting of the flower-stems the plant's period

TULIPA 



It is a matter of great regret that the key used be- 

 low is based upon a technical botanical character of no 

 interest to the horticulturist, but it seems to be impos- 

 sible to group the species according to the color and 

 shape of the flowers.
