CHAPTER III 



GAMOPETAL^ (FLOWERS WITH TUBULAR 

 COROLLA) (= MONOPETAL.^ OR GOROL- 

 LIFLOR^) 



ALL the members of this sub-class, with some 

 exceptions, agree in having a perianth in two 

 whorls, or dichlamydeous, and the corolla tubular. 

 The petals are more or less united into a two- or 

 more-lobed corolla. This characteristic has, how- 

 ever^ been noted as occurring in the Thalamiliorae 

 (vide Chapter I), as in the Fumitory group. Milkwort 

 group, Purslane group, Tamarisk group, Mallow 

 group. Holly group, in Navelwort, in the Stonecrop 

 group, in the White Bryony group. 



There are some exceptions in this group to the 

 above general rule. The petals are free in the Heath 

 group, in the Winter green, and Bird's Nest, and 

 in the Sea Lavender group. The corolla is absent in 

 the Ash in the Ash group, and in Sea Milkwort 

 in the Primrose group. 



The ovary is inferior and the stamens are epi- 

 petalous in the Honeysuckle group, Bedstraw group, 

 Valerian group. Teasel group, Dandelion group, and
