Notes on the Illustrations in this Issue. 
Our illustration of this beautiful native plant taken in the 
water garden at Aldenham House shows many thousands of 
plants completely obscuring the surface at one end of the pond. 
The plant has the faculty of throwing out runners after the 
fashion of a Strawberry, producing a young plant at the end of 
the floating stem. When the young plant attains soma size 
it' begins ramifying on its own account. Growth is thus very 
rapid 1 , and in the course of a few months the entire surface of 
the water for a considerable distance around the parent colon.} 
gets covered up with small orbicular leaves resembling those 
of a Water Lily in miniature. As soon as each plant gets 
strong enough it throws up flowering stems:, each, hearing a. 
large, bright yellow flower beautifully fringed. Those who 
have once seen this plant cannot help being taken with its 
quaint but quiet beauty, if it could be confined within de¬ 
sirable limits. Its inclination is to multiply so rapidly that 
it soon requires weeding out to prevent it from covering the 
entire surface of the water similar to that of the pond which 
we illustrate. There can be no doubt., however, that it is one 
of the most interesting and 1 beautiful aquatics, and so 1 easily 
cultivated that it can 'be grown in the smallest pond or in a 
tub* if the cultivator cannot spare more space for it. 
Lake and Grotto at Aldenham House. 
Around the edge of this pond in the water garden many 
Bamboos and water-loving trees have been planted. Many of 
these are' British, or may be Continental varieties: of the same. 
Salix babylonicai annularis is an exception, being the annular- 
leaved form of the Babylonian Willow from Japan. Amongst 
the Willows are various, forms, of S. purpurea, including - S. p. 
pyramidalis Eugenie, S. lamina, a supposed natural hybrid 
between A. nigricans and Caprea, also S. nigricans and S. 
grandiflora mosiohata. A collection of Alders has also been got 
together, including Alnus incana. aurea, which has golden leaves 
in spring. Very handsome: also is A. glutinosa, rubrinerva, 
with red veins to the leaves and ai bronzy cast on the upper 
surface. The large leaves of Gunner a manicata, are also very 
effective on the edge of the water. 
The Lake at Aldenham House. 
Accompanying this we give an illustration of the smaller 
lake at Aldenham House, Elstree, Herts., the beautiful seat 
of Lord Aldenham. This might, indeed, be described as hut 
a part of the large lake, seeing that the two are merely 
separated by the roadway or drive which is carried over the 
lake at a. narrow portion by means of a bridge. In giving this 
portion we miss a number of the aquatics, particularly the 
Common Reed (Pliragmites communis) which forms such a 
feature on the margin of the lake, and might very well be 
described as the British Bamboo. Though it may be somewhat 
distantly allied, it, is, nevertheless, a Grass, but the stems die 
away naturally in, the case of those:, at least, which have 
flowered. The: stems, are 6 ft. to 9 ft. high, and form dense, 
masse® flowering in August, after having been established a 
few years. 
Returning to the smaller pond at the lower end of the lake, 
our readers may notice something on the water at the left- 
hand corner of the picture. This is the White Water Lily, 
which has been largely utilised on the orna¬ 
mental water in various parts of the grounds. 
On the opposite side of the water is a grotto', 
artificial it is true, but the effect and interest 
attached to it is considerably heightened by 
its rising directly out of the water. The 
stones are built up to represent the outcrop of 
natural rock, such as one often meets with on 
the margins of lakes and rivers. 
As will he seen, the shrubbery is: a, very im¬ 
portant feature in this 1 view, and we may add 
that this is also the case in various parts of 
the pleasure grounds and woods of Aldenham 
House, quite apart from the better-kept, 
grounds in the neighbourhood of the mansion 
itself. Ornamental trees and shrubs are so 
numerous on this estate that it might: well he 
regarded as an arboretum akin to a botanical 
garden. In the neighbourhood of 'the water 
the effect is chiefly produced by species of 
Barberry, Gorse, Golden Privet, Fiery Them, 
Cotoneiastersi, Ivy, and one of the Japanese 
Bamboos, Arundinaria japonica. Some 
writers 1 on the subject of trees, condemn: the 
Lombardy Poplar, but it cannot be gainsaid 
tliat a judicious disposal of trees produce® a 
very distinct and marked effect in the land¬ 
scape, as will be 1 seen by the few free® which 
come into, this view. 
On the bridge sep.ara.ting the two portions of the lake was. a 
fine piece of Salpichroa rhomboidea, with small, white, bell- 
shaped flowers produced on rambling, zigzag stems covered 
with very small rhomboid or lozeng&shaped leaves. bornei 
people lia-ve styled this the Lily of the \ alley plant. n ot lei 
parts of this large lake not shown in the. view are massive 
hanks of the larger and smaller Reed Mace (Typha, latifolia 
and T airustifolia), both British plants of the easiest cul¬ 
tivation, provided there is a plentiful supply of moisture, such 
as can always be obtained by planting m shallow water at the 
edges of ponds. They even succeed in place® that are merely 
boggy, hut the: best effect is- always obtained when planted m 
the water, so as to. keep down the grass: and other weedy 
vegetation, which shows off the beauty of the foliage of the 
Reed Mace to advantage. 
Limnanthemum peltatum. 
Bv the above name we refer to the Fringed Buck Bean, a 
British plant with yellow flowers. Various, names have been 
given to this, plant, and there is not a little confusion. In 
some books; it will be found under the. name of Limnanthemum 
nymphaeoides, L. nymphoides and Villa.isia. nymp 101 es. 
According to the Index K even sis, the correct name is as we 
C5 
have given it above. 
Clerodendron trichotomum. 
In districts where this can be grown, in the open air it forms 
a beautiful and interesting addition to the shrubbery. The 
accompanying illustration shows, a, plant that was taken about 
the middle of August at Aldenham House just when the flowers 
were commencing to open, These are produced in cymes at 
the end of eveiy branch and shoot, and, owing to. the fact that 
flowers are expanded a few at a time, a succession is kept up
