Germination and Growth of Species of Salvia. 3V7 



In the largest individual, . . 42 mm. 



In average sized, . . . 20 „ 



In the smallest, . . . 10 „ 



Jan. 22, 2 p.m. Of one seedling it is noticed that it has 

 drawn its young leaves together by 14 mm. 



Jan. 22, 6 p.m. After having been out in the open air 

 during the afternoon, the seedlings were brought into the 

 warmer, drier air of the room ; all showed the leaves widely 

 separated. In selected seedlings the distances apart from tip 

 to tip were as follows : — 



A. (largest seedling.) B. 



3rd and 4th leaves, 42 mm. 3rd and 4th leaves, 20 mm. 

 1st and 2nd leaves, 46 ,, 1st and 2nd leaves, 43 ,, 

 cotyledons, 18 „ 



3rd and 4th leaves, 25 mm. 

 1st and 2nd leaves, 44 „ 



Jan. 23, 8 a.m. — Tlie measurements of the above were :- 



A. B. 



3rd and 4th leaves, 28 mm. 3rd and 4th leaves, 25 mm. 

 1st and 2nd leaves, 46 „ 1st and 2nd leaves, 42 „ 

 cotyledons, 18 „ 



3rd and 4th leaves, 20 mm. 

 1st and 2nd leaves, 43 ,, 



It is probable that we have an explanation of the 

 movements at first recorded, in the fact that on the morning 

 of the 23rd the exhibited movement was less evident, 

 indeed, hardly noticeable. The plants had, on this occasion, 

 been placed in a cooler place in the room, and not, as 

 before, within a couple of feet of a wall, where was a flue of 

 hot air. 



The movements of the leaves of >S'. canaricnsis may be 

 compared with the movements exhibited in S. interriipta, 

 the seedlings of which species were only twenty-five days
