evergreen; the plant increases rapidly, and in a few 

 years may be planted to a great extent. S. speciosa has 

 red flowers, crowded in spreading panicles. S. tatdrica 

 has also very showy flowers, and is now given to the 

 genus Taxdnthema. S. latifblia and S. maritlma are the 

 finest. T. latifblia |and T. conspicua deserve attention. 

 They should be lifted every alternate year, and sunk 

 deeper into the soil, because they incline to grow out, 

 and are sometimes during summer killed by the drought. 

 Hence they are said to be " bad to cultivate." 



Trollim europceus, and T. asidticus, are fine border 

 plants, with large yellow semi-double flowers; the petals 

 are much cupped, which causes the flowers to have a 

 globular appearance. They are easily grown in any 

 loamy soil, and flower from May to July. Few flowers 

 have the curious globular character which these have. 



Veronica, Speed-well This genus consists of about 

 one hundred and twenty species of herbaceous plants, 

 besides several varieties. The flowers are in long 

 close spikes, either white, flesh coloured, or blue ; they 

 are generally of the latter colour. Above sixty species 

 are equally fine, and being generally of the same cha- 

 racter, the Catalogue at the end of this work will con- 

 tain the best selection that we can make. Very few 

 of them are in the collections of the country, although 

 they are very showy, and flower from June to August. 

 They will grow in any soil, but will not flourish where 

 they are much shaded. V. officindlis has been used in 

 Germany and Sweden as a substitute for tea. Some 

 prefer V. cham&drys for the same purpose.
