Cult. Luxembirgia is a genus of truly elegant shrubs, with 
large beautiful yellow flowers, and serrated, shining, stiff leaves, 
having the habit of some species of Rhododéndron. None of 
the species have been introduced to the gardens of Europe, there- 
fore the mode of cultivating and propagating them in the gar- 
dens is unknown; but should any person be fortunate enough 
to introduce them in a living state, we recommend their being 
grown in a mixture of loam and sandy peat, giving them plenty 
of water in the summer season. Young cuttings will no doubt 
root freely ina pot of sand, with a bell-glass placed over them, 
in heat.
