other genera of this order. There are several 

 species of Lycium, which are all known by the 

 English name of Box- thorn; but L. harharum is 

 also called the Duke of Argyle's Tea-tree, from 

 a story told of this plant being sent to a 

 Duke of Argyle early in the last century, instead 

 of the true Tea-tree. The story, however, 

 is very doubtful ; and the more so, as in France, 

 the dwarf Chinese Elm is called The de TAbbe 

 Gallois, as it is said, from a similar cause. 



Cestrum Parqui is a very handsome half-hardy 

 shrub, which may be placed in this division 

 from its berry-like fruit. It has a funnel-shaped 

 corolla, with a five-lobed limb, enclosing its five 

 stamens. The flowers are disposed in an upright 

 raceme ; they are yellow, and very fragrant. 

 The berries are of a very dark blue, and almost 

 black when ripe. Vestia is another genus very 

 nearly allied to Cestrum, but the stamens project 

 beyond the mouth of the corolla instead of 

 being enclosed within it ; and the flowers, which 

 are produced singly, have a very disagreeable 

 smell.

The plants included in this tribe agree with 

 those of the preceding division, in having the 

 corolla generally folded in large plaits in the
