HELLEBORUS. Im this genus it is the Christmas 
Rose section rather than the Lenten Rose one which is 
popular. The latter, however, is quite distinct from the 
former, and should always be represented, the flowers 
being produced at the time suggested by the popular

name. Some beautiful varieties of Lenten Roses have been 
produced by the florist from H. orientalis and H. viridis. 
These require to be planted in shade and in a good rich 
loam, and to be disturbed as little as possible. During 
dry summer weather the plants should either be mulched 
or well watered; and occasional soakings of weak liqnid 
manure are beneficial, When dividing up Lenten Roses 
this should be done as soon after flowering as possible, 
April being a good month for the work. 
Hellebores suffer badly in some seasons from a destrnc- 
tive fungus, Phoma effusa. This is noteworthy from the 
fact that it lives first as a saprophyte on humus in the 
soil, and afterwards becomes parasitic. The infested 
portions should be remoyed as soon as noticed, and 
burned, before they can ripen the spores which are 
scattered in every direction by different agencies. 
Beyond this little can be done the season the disease is 
noted. Next season, however, as soon as the leaves 
appear, they should be sprayed with a solution of 
potassium sulphide, repeating it after ten days or so. 
To the species and varieties described on pp. 182-3, 
Vol. I1., the following should be added :

H. hyemalis (winter). 
H. olympicus. Of this well-known kind several very desirable 
varieties are in commerce: major, pure white; roseus, soft 
pink ; and superbus, white, large.

Varieties. Of the Lenten Rose section the following 
varieties of H. orientalis are all worth cultivating : 
AFGHAN PRINCE, deep purple; APOTHEKA BOGREN, purple, 
elegantly spotted; BISMARCK, vinous purple; CHANCELLOR, 
clear rose, fine flowers; COMMERZIENRATH BENARY, white, with 
crimson spots, imbricated; DR. HoGG, deep rose; IRENE, soft 
ink ; LASANDRA, rosy-purple, veined and spotted; Mrs. 
AMBERT, blush white, spotted crimson; PSYCHE, soft pink, 
blotched crimson; SYLVIA, rose; W. E. GLADSTONE, soft rose, 
with pink shadings. 
Of H. viridis varieties there is not such an attractive 
colour range, nor is the foliage permanent. Nevertheless 
Columbine, dwmetorwm, Ellen Terry, and erubescens, to- 
gether with the type, should, if possible, have a place in 
the border, as they are distinct. For naturalising, how- 
ever, they are still better adapted, the shade of the wood- 
land suiting them to a nicety.

HELMINTHOSTACHYS. Indian Flowering Fern. 
H. zeylanica is a species somewhat difficult of cultivation, 
requiring stove temperature all the year round and a con- 
stantly moist place. The best compost consists of two 
parts rich loam, one part leaf-mould, and one part sand. 
Propagation is very slow, as it very seldom forms double 
crowns, and young plants have neyer, it is believed, been 
raised from its spores, which are disposed in small, crested 
clusters, forming a long, loose spike of peculiar shape, 
Being deciduons, care must be taken that, during the 
resting season, its roots and rhizome, both of which are of 
a succulent nature, do not become dry, in which case 
it would seriously suffer and possibly die outright. 
H. zeylanica is of little value as a pot plant, but highly 
interesting when grown in a warm Fernery in a moist 
situation, where it does not get disturbed during the 
resting season.
