PART IV. CLASSIFICATION. 



Andes, but cultivated in Java and the East Indies, yield the cinchona bark 

 from which Quinine is prepared. Bouvardias are ornamental greenhouse 

 plants from Central America. 



Order 2. CAPRIFOLIACE.E. Flowers usually pentamerous, actino- 

 morphic or zygomorphic : corolla usually with imbricate aestiva- 

 tion ; gynseceum 2-5-merous : ovules suspended : fruit baccate ; 

 seed with endosperm : leaves opposite, usually exstipulate. Mostly 

 trees or shrubs. 



Tribe 1. Sambucece. Flower regular, sometimes completely actmomor- 

 phic, corolla rotate (Fig. 274 C) : one ovule in each loculus. 



Sambucus has a 5-partite corolla, and 3-5 seeds in the berry ; S. nigra is 

 the Elder ; S. Ebulus is the Dwarf Elder or Banewort. Viburnum has a 

 5-partite corolla, and one seed in the trimerous berry, two carpels being

abortive; V. Lantana and V. Opulus, the Guelder Hose, are common; a 

 form of the last species is cultivated in which all the flowers (and not 

 merely those at the circumference of the corymb as in the original species) 

 have a large corolla, and are barren ; V. Tinus is the Laurustinus. Adoxa 

 nioschatellina-j the Moschatel, is a small plant occurring in damp woods: its 

 flowers are 4- or 5-merous ; it appears that there is no calyx, that which is 

 regarded as the calyx being probably an involucre of bracteoles and bract ; 

 the stamens are each divided into two, so that there are 8-10 bilocular 

 anthers. 



Tribe 2. Lonicereae. Flowers more or less irregular, zygomorphic ; 

 corolla tubular : loculi containing several ovules. 



Lonicera, the Honeysuckle, has a somewhat bilabiate corolla (Fig. 392), 

 and a 2-3-locular ovary ; L, Caprifolium and Periclynienum, with a climb- 

 ing stem, are well-known garden shrubs ; in many species the fruit of two
