 probably due to an intimate fusion of the lower portion 

 of the bract (which became at the same time excep- 

 tionally elongated) with the pedicel. 



3. Op Foliage-leaf to Perianth-leap. — This is the 

 case above-mentioned in the tulip where the upper 

 apical part of the foliage-leaf became laterally fused 

 with the entire length of one of the sepals, so that the 

 latter was partly petaloid and partly foliaceous.
