lumular leaves, which shew a decussate arrangement, are more or 
fate ovate, glandular, and have a well-marked mid rib. In the 
course of two months the young shoot has reached the stage shewn 
in Fig. 1, and at the end of seven months the seedlings have grown 
to the size shewn in Figs, 2 and 3. 
The development of the tubers below ground proceeds somewhat 
slowly as shewn in the figures :—

At the end of two months the tap root had swollen to form an 
elongated fusiform tuber 1 em. long by about 2 mm, in diameter, 
and during this time it is 
pulled deeper into the soil by the action 
of root shortening. The tuberous root in the largest example, 
~ 3, is some 4—5 cm, in length and 9 mm. in diameter.
