The study of the Linnean system is short and easy ; 
that of the Jussieuean, and those subsequently built on 
it, more lengthened and intricate. Knowledge is cer- 
tainly imparted by its circuitous route; yet consider- 
ing how many turn, with alarm, from the threshold 
of the most simple method, we regret any increase 
of these fears. The natural arrangement offers many 
important advantages, but let us remember, with due 
praise to its promoters, that these can be embraced 
when the Linnean is acquired. 
Numberless varieties, between the Azalea and 
Rhododendron, may hereafter be raised. We hope 
that many of our readers will give their exertions to 
the increase of these beautiful shrubs. It is most rea- 
dily effected ; being merely the removal of the anthers, 
from the flowers of one plant, soon after it has opened, 
and bringing to the style of that flower, the pollen 
of another species. From the seed produced by a 
flower, thus artificially impregnated, will spring 
hybrid plants, partaking of the characters of each of 
the two species employed. 
Choice will, of course, be made of those Azaleas 
or Rhododendrons which are known to perfect their 
seeds; and the two flowers experimented on, should 
be such as have opened on the same day. The de- 
struction of the one set of anthers must be effected as 
early as possible ; and those to be made use of should 
be taken when they are beginning to burst and dis- 
charge their pollen or farina. A little observation 
of the economy of nature, in the fructification of ve- 
getables, will enable any one to act with a great de- 
gree of certainty as to the result. Remarks on cul- 
tivation will be given at a future opportunity.
