or roundish, with 5 angles. Styles (fig. 5.) 5, thread-shaped, either 
longer or shorter than the longest stamens. Stigmas blunt, downy.

lengthwise at the angles. Seeds roundish, polished, with an elastic 
arillus, in some species solitary, in others several in each cell.

t This plant, says Geuardb, is called by herbalists, Alleluja, ami Cuckoo's 
Meat, because it springs forth and flowers with the singing of the cuckoo, at which 
time Alleluja also was wont to be sung in churches. The names Alleluja and 
Lujula are, however, corrupted from the Calabrian name Juliola. It is probably 
called Stubwort from its covering the ground among the stubs in coppices, when 
they are cut down. Don.
