PAPAVERACEAE 55 
Adiantum farleyense ; the flower-stems reach to five feet 
or more at their best, and carry far on down the season a 
wide foaming mass of white blossom, which, in one form, 
is pale purple. No plant is handsomer for the big bog- 
garden, or the cool border. Delavayi is a novelty, and a 
little uncertain so far. It seems everything that it should 
be, and in growth is like a dense robust minus, with 
leaves of a metallic bronzy grey. The abundant flowers 
are of a very pretty, soft mauve, and large enough to 
make quite a feature. 
Isopyrum thalictroeides is a wee cousin of the Thalic- 
trums, very close to them, and of perfectly easy cultivation 
in light loose soil, rather poor than rich. The plant is 
quite small and graceful, with the fine, dainty greyish- 
green leaves of its kind, and three or four charming little 
white flowers carried on short foot-stalks, very early in 
the season. It is a Swiss plant, but not, I fancy, very 
common. I have never seen it wild, and believe it to be 
rare—at all events in Western Switzerland and the Ober- 
land. 
This, I think, covers nearly all the Ranunculacez that 
are valuable in the rock-garden. ‘The little false Aconite 
of early spring is too common, and the big true Aconites 
too large and too wicked to find any place in the rock- 
garden. One need not look twice at any Monkshood to 
see that he is an evil, poisonous person. So away with 
them all, unless you admit the beautiful white Levantine 
album, or the new twining volubile. 
Sanguinaria canadensis, with its variety called major, 
is so like a cousin of the Buttercups and Anemones that 
he must certainly come next. He occupies a certain peaty 
bed in the Old Garden underneath my big bushes of 
Magnolia Kobus and Magnolia Watsoni. "The Canadian 
Bloodroot is so called because he bleeds. When you dig 
up his fleshy tubers they ooze gore in a most unpleasant
