narrowness of petal, and its habit of sitting close upon 
the leaves. T'rilliwm erectum and T'rilluum stylosum are 
dull, to my taste, and dowdy,—pink and purple. T'rilliwm 
erythrocarpum is a tiny jewel, delicate and rather difficult, 
small, with snow-pure flowers, like miniatures of grandi- 
florum, but with a blotch of blood-crimson at the base 
of each segment. This requires attention on the choice 
peat-bed, but all the others thrive in any open woodland 
soil, free and moist, luxuriating in the filtered light of a 
thin copse or hollow in the woods. However, the Wood- 
lilies, blooming in May and June, though lovely by the 
water-side, are perhaps more glorious still for the lily- 
bank and copse and rockwork. They have great resisting 
power, too, for I remember seeing one in Hokkaido— 
probably Trillium secundum, a small version of grandi- 
florum, coping successfully with the roots of Bambusa 
Veitcht. ‘The Bamboo covered the country by the mile, — 
and not a square inch of soil can have been free of its 
roots. Yet everywhere amid that two-foot jungle were 
visible the white stars of the T'ridliwm, quite unsubdued 
by the rambling growth of the Bamboo. ‘This, however, 
must not be literally presumed on in the garden. Except 
into the wild garden there is not a Bamboo that can be 
trusted—making an honourable exception for Maaimo- 
wiczit and erecta, graceful and effective, like Pampas and 
stripe-leaved Hulalia zebrina, at the edge of the water. 
Now dive we into the depths of the pond itself. From 
two to three feet is the happiest depth for beautiful Pon- 
tederia cordata, with broad, splendid leaves, and tall spikes 
of blue flowers that unfold too late in the season to be of 
any use to me. The Pontederia will also grow in shallower 
water, but one wants to avoid, as far as possible, the peril 
of frosts. The same applies to the even more splendid 
and tropical Thaleia dealbata, which is hopeless for my 
climate, and to the common Arum of the greenhouse.
