reaches a height of 4 feet on an average, sometimes even 10 feet, and occurs in gorges, — ‘ 
200 to 1000 feet above the sea level, between shrubs and granite debris, in the shade ag 
of trees. Black, sandy clay containing a considerable proportion of decayed veges 
matter, is reported to be specially favourable for its growth. : oe, 
2. Barosma betulina (Mountain buchu) is probably the most valuable kind.. It is’ as, 
more compact and smaller than B. serratifolia, reaches 3 to 4 feet in height and is ’3 
found frequently on slopes about 1000 to 2000 feet above sea level. Red, sandy clay %

The buchu. shrub is not satisfied with every kind of soil. Its natural habitat is- 
neither on calcareous, nor on saliferous, sandy or heavy clayey soil. It is said that 
the cultivation succeeds best on sandy, well-drained and deeply plousnee clay, which 
is not watered by salt rivers. 
The buchu plant can be propagated through seeds and. slips. The. seeds are 
generally sown before the cold season, in seed frames or on beds. The former are 
mostly filled with a mixture of equal parts of mould and sand, placed on a ‘shaded a 
warm spot and kept damp. The seeds, which ought to lie 14/4 em. under the suttare i 
germinate after some weeks, after which the frames can be exposed to the morning ~ 
sun. Afterwards, only a protection against frost and sharp wind is necessayy, and a: a 
' soil must be kept moderatly damp, but absolutely free from weeds. - 
If the seeds are sown on beds, these must be dug over very deeply, the’ soil being @ 
partly replaced by mould and sandy clay. They are often covered with branches, as to

have a little more sunshine, so long as it is not too glaring. M 
Transplanting generally takes place when the air is not too ‘dry. The aah i
