limbs are short, they are spoken of as teeth. In a 

 gamosepalous calyx the number of sepals is determined 

 by counting its limbs or teeth. 



The gamosepalous regular calyx 

 may assumevarious forms, of which 

 the following are very common, 

 namely: tubular (see fig. 215), as 

 in dhutura, taru-lata {Quamoclit 

 pinnata); campanulate or bell- 

 shaped, as in jaba or Chinese Rose. 

 The calyx, whether gamosepalous 

 or polysepalous, is often rendered 

 irregular when its base is prolonged 

 into a pouch or sac. If the pouch 

 is short, the calyx is said to be 

 GIBBOUS, as in Mustard; when the 

 pouch is long and tapering, the 

 calyx is said to be spurred (fig. 

 79), as in dopati {Impatiens Bal- 

 samina), Garden Nasturtium, and 

 Larkspur. 



The calyx is said to be caducous 

 when it falls off as soon as the 

 flower begins to expand, as in 

 Poppy (fig. 80) and shial-kanta; 

 deciduous when it falls off along 

 with the petals after the flower 

 expands, as in most flowers; per- 

 sistent when it does not fall off, but 

 persists as a part or covering of the 

 fruit, as in tulsi ; and accrescent 

 when it is not only persistent, but 

 also grows along with and forms part of the fruit, as 

 in begoon, sal (see fig. 165), sagoon, and chalta {Dil- 

 lenia indicd). Sornetjnies the calyx consists of a circle
