HYBRID AROIDS. 
Asnearly as I can remember it is about fifteen years 
"c Kellermann's hybrid Aroids were first exhibited 
at a flower show in Erfurt, the metropolis of German 
gardening ; and even then they were objects of great 
interest, especially to botanists € ol gence In the

the position of under gardener in the Im ardens

director, in his preference for Aroids, had gradually 
brought together the richest collection in existence ex

soon arrived at the conclusion that these plants were 
peculiarly adapted for giving an insight into the true 
nature of hybrids. This induced him to commence a 
series of cross-fertilisations, which by degrees led to 
highly interesting results, the exposition of which is
