Among the more familiar species in collections it also 
approaches rather closely to /, laevigata, Fisch., but may 
be at once distinguished by its narrower, more sharply 
pointed spathes. The rich dark purple flowers with their 
velvety texture render the plant a very conspicuous object ; 
the colour is well set off by the central line and. the 
broken flanking streaks of golden yellow. These flanking 
streaks vary somewhat in number and extent, sometimes 
they are almost absent and only the central golden yellow 
line appears. Another species closely allied to I. chryso- 
graphes is I. Delavayt, Micheli, from Yunnan, which has, 
however, a different capsule and seeds, and as a garden 
plant is readily distinguished by its taller stature and by 
its blue purple flowers with white markings. Mr, Dykes 
finds that J. chrysographes is not difficult to grow in any 
soil that is fairly rich in humus and is not heavily charged 
with lime. It appears not to demand either the excessive 
moisture or the very retentive soil in which J. Delavayi 
best succeeds.
