ISOTOMA FLUVIATILE. 
advance in the world with almost equal celerity, whether much care 
be deployed upon them or none at all. (Root disturbance is best 
avoided.) When raised to months of discretion, too, there is every 
reason for us to rejoice in the prosperity of this unique loveliness, 
under the same conditions of careful culture that make the happiness 
of choice Saxatile treasures, so long as it has a well-drained 
depth. 
Isotéma fluviatile is a little New Zealand Campanula of the 
bogs with small pale-blue flowers. 
Ivesia Purpusii. See under Comarella. 
J 
Jaborosa integrifolia is a dwarfish, creeping-stemmed Solanoid 
from the Andes, with large foliage and fragrant long-tubed starry 
flowers of greenish white. It wants deep warm rooting room, and 
is not very hardy or trustworthy or lovely. 
Jankaea Heldreichii, on the contrary, deserves all the care it 
exacts. For this lovely thing makes rosettes like those of Ramondia, 
but silvery with a dense pelt of white down, so that it is obvious that 
no place will suit it where water falls or lodges. Let it then be planted 
in rough, coarse, sandy peat with plenty of grit, in such a hollow of the 
overhung rockwork or hole of a stone as can never be visited or corroded 
by rain, and there its silver flat rosette will take no hurt and continue 
to shine untarnished, till one day in June or July you will see the stems 
spring up some 2 or 3 inches and unfold their spray of ample little 
Gloxinia flowers, which are of palest clearest lavender, and of a 
texture so thick and crystalline that they seem to have been carved 
from tinted snow, glistering all over their substance with minute 
sparkles of light. This can be raised with care like Haberlea from 
seed, and, like Haberlea, Ramondia, or Begonia, it can also be made 
_to root from the leaves struck in sand, with the greatest care, about 
July, and nurtured up in heat. It is the pride of Thessaly and its 
shady mountain walls. 
Janthe (Ianthe) bugulifolia.—tThis is a Celsia or Mullein of 
a weird aitractiveness, about a foot high and closely suggestive of 
Verbascum phlomoeides in habit of loose basal rosette, but with spires 
of blossom in the strangest tones of greenish blue and metallic bronze, 
evilly spotted with black or purple, from June to September, opening 
in succession round the spike.
