STIPULES

the stipules form a complete sheath surrounding the 

 axis (like the sheath of CYPERUS, but above the point 

 of attachment, not below it). 



In the Banyan, Fig, Jak, and a number of other 

 plants the stipules are also in the form of a tube 



which at first completely 

 surrounds and covers the 

 young bud above the leaf. 

 As the internodes of the 

 bud lengthen and each leaf 

 opens out, the stipule splits 

 into two and is then like 

 the normal pair of stipules 

 but soon falls off, and the 

 only sign left is a scar 

 running round the axis. 

 The same happens with 

 MICHELIA, a plant in every 

 other respect very differ- 

 ent from the Banyan. In 

 a few other plants too 

 the stipules are so large 

 that they completely sur- 

 round the axis, and leave 

 a scar not unlike that of 

 FIG. 6 the Banyan or Fig, or of 



HIBISCUS TILIACEUS MICHELIA, though not like 



these, tabular in shape, e.g. in HIBISCUS TILIACEUS 

 {fig. 6). 



4. If the blade of a leaf be single and undivided, as, 

 for instance, the Mango, Banyan, Fig, Cotton, Tobacco 

 and Hibiscus, it is said to be simple. But if it is
