SHAPE OF COROLLA 211 



looks as if the petals were joined together somehow 

 at the base). 



2. But in any case whether monopetalous or poly- 

 petalous, the shape is described as 



regular, if of a general circular form, e.g. a flat 

 plate as in Brinjal, or a funnel-shaped tube as in 

 CONVOLVULUS, so that it could be divided into per- 

 fectly symmetrical and similar parts in any direction 

 through the axis. 



irregular if one side (generally the lower or the 

 upper side) is larger than the other, so that it could 

 be divided into two equal halves only in one plane 

 through the axis (generally from back to front). 



3. The shape of the corolla, or of the calyx, is 

 further described as 



Stellate, if flat with pointed lobes or petals like the 

 conventional rays of a star, as in the corolla of 

 the Brinjal, Chilli, etc. 



tubular, if cylindrical of about the same width 

 throughout, as the corolla of SESAMUM and RUSSELIA. 



campanulate if narrow at the base but soon widening 

 with straight sides, like an inverted round bottle with 

 a very short neck, or like an old fashioned or a 

 Japanese or Burmese bell, as the corolla of CUSCUTA 

 CHINENSIS the Dodder, and the Canterbury-bell. 



trumpet-shaped, if narrow at the base and widening 

 gradually like the end of an oboe or trumpet or like 

 an ordinary modern bell, as the corolla of IPOM^EA 

 and CONVOLVULUS. 



salver-shaped, if with a narrow tubular part which 

 spreads out sharply and widely at the top, as the corol- 

 las of VINCA, the Periwinkle, CERBERA ODOLLUM.
