B. socotrana,. Seedling hybrid forms have been obtained by 
crossing the summer-flowering, tuberous, garden varieties with 
B. socotrana. The following are of great horticultural value, and 
the richly-coloured sprays of flowers are valuable for placing in 
vases : ADONIS, flowers rosy-carmine, medium-sized, leaves large 
and handsome, habit robust and erect; AUTUMN Roskr, flowers 
rose-pink, pretty, intermediate between those of B. incarnata and 
B. socotrana (the pollen parent); JOHN HEAL, flowers clear rose, 
lasting for two or three weeks, leaves much smaller than those 
of ADONIS, habit graceful; WINTER Germ, flowers more crimson 
than carmine, freely produced, leaves rhomboid, more like 
B, socotrana than the other hybrids. The first three can be 
freely propagated by cuttings ; but the last can only be increased 
by the small tubers at the base of the stem. 
Varieties. The improvement in this popular greenhouse 
flower has been quite marvellous during the last few years. 
The single and double varieties of the tuberous section 
have been obtained of the finest form, and of the richest 
and most varied colours: white, blush, pale rose, and 
salmon to the richest, darkest crimson. We have also 
clear yellow, orange, bronze, apricot, and such tints as 
are seldom seen in garden flowers. The following is a

BERBERIS. Nearly 100 species have been described
