anatropous ovules with axile placentation. The fruit is usually a capsule 

 or rarely a berry. The seed is endospermic. 



A number of genera are grown in gardens. Phyteuma, Jasione, Platycodon 

 and Lobelia may be mentioned, but by far the commonest is Campanula

with 300 species, eight of which, including C. rotiindifolia (Harebell), occur 

 in Britain. 



Another small order, the Plumbaginales, contains the single family 

 Plumbaginaceae with some ten genera and about 260 species. The plants 

 are perennial shrubs or herbs, 

 with narrow leaves often pos- 

 sessing water glands. The 

 flowers are regular and pentam- 

 erous. The calyx is persistent 

 and the stamens are opposite the 

 petals. The ovary is superior, 

 unilocular and contains a single 

 ovule. 



Among the common genera 

 is Statice with about 130 species 

 which are cosmopolitan in dis- 

 tribution but are found chiefly 

 in salt marshes and on steppes. 

 S. limofiium is the Sea Lavender 

 (Fig. 1808) which is common in 

 Britain. The flowers are often 

 heterostylous. The closely re- 

 lated Armeria (Sea Pink or 

 Thrift) is found in similar 

 situations. Plumbago, with ten
