326 HORTICULTURAL TOUR. 



there are about forty species, several of them very scarce 

 in England, and to be found only in the collection of Mr 

 Griffiths at South Lambeth, or of the Hon. and Rev. Mr 

 Herbert at Spofforth in Yorkshire. Twenty species of 

 Passiflora arc trained along the rafters, and several were 

 now covered with flowers. In the genera Banisteria, Fi- 

 ens, and Gardenia, the collection is rich. 



In the greenhouse, the Norfolk Island Pine (Araucaria 

 excelsa) had some years ago reached the glass-roof. Mr 

 Parmentier was not in circumstances sufficiently affluent to 

 render it convenient for him to erect a lofty conservatory 

 for the sake of an individual plant : he therefore judged it 

 best at once to cut it over at the height of seven feet. Its 

 horizontal branches are now spreading very widely ; but 

 there is no appearance of any of them sending forth a lead- 

 ing shoot, to supply the place of the upright stem which 

 has been lost. Mr Parmentier has succeeded in striking 

 some young plants from the cuttings thus unwillingly forced 

 upon him. But it seems probable that these also will never 

 form symmetrical plants ; for they continue to exhibit all the 

 characters of brandies merely, without shewing the least ten- 

 dency to form leading shoots or stems. The Spruce-fir, 

 however, (a tree analogous in general character to the Nor- 

 folk Island pine), when deprived of its leader, has been re- 

 marked to make efforts for supplying the deficiency after 

 the lapse of many years. 



Clelhra arborea, with finely variegated leaves, attracted 

 our attention : it is a beautiful variety, and very scarce in 

 England. Of the genus Paionia there are no fewer than 23 

 species and varieties, including P. papaveracea, and both 

 the paJeand dark varieties of the moutan. Of Camellia 

 Japonica, Mr Parmentier has procured 1 4 varieties, chiefly 

 from London. In the genus Protea lie is extremely rich,
