Fagrfea were formerly included in this order ; 

 but the first is now placed in the new order, 

 Theophrastese (see p. 899) ; and the second is 

 placed in another new order introduced here, 

 and called Potaliacese. 



ORDER CXXYII.— APOCYNE^. 

 Vert showy plants from various parts of the 

 world, some of which require a stove in Britain, 

 while others are quite hardy. They also vary 

 in some of them being trees, others erect shrubs 

 or climbers, and others perennial ; but they 

 are all easily recognised by the twisted direction 

 of the segments of the corolla, which has been 

 compared to the rays of St. Catharine's-wheel. 

 The corolla is generally salver- shaped as in the 

 periwinkle (^Vinca major), or funnel-shaped, as 

 in Taherna montana, and Allamanda cathartica, 

 or divided into equal segments as in Nerium 

 Oleander. The flowers are often bearded in the 

 throat, and furnished with hypogynous scales ; 

 with the stamens inclosed in the flower, and the 

 anthers lying close together. The seed is contain- 

 ed in two ibllicles, which are slender, and have 

 their seeds disposed in two rows. The species all 

 abound in an injurious milky juice ; and two of 

 the genera, Cerbera and Tanghina, are virulent 

 poisons.
