yellow flowers may be seen on the surface without any leaves 
in company with them in places where the water is deep. 
Whether the flowers of Water Lilies should lie on the surface 
of the water or rise above it is a matter of taste. It would 
be advantageous, however, for them to rise higher than the’ 
leaves, whatever their behaviour may be. Unless they do rise 
in this fashion, the flowers are liable to be hidden, even 
when produced in great quantity on well-established plants, 
and their effect is lost. From this point of view it would be 
an advantage if hardy Water Lilies were to lift their flowers 
upon a stem so as to stand clear of the foliage. This improve¬ 
ment might be effected if cultivators or raisers should succeed 
in crossing some of the hardy species with N. gigantea. 
Usually, this species is grown in a tank of a stove in a 
house with a very high temperature, but it may be grown in 
a relatively cool house, and, such being the case, it might 
possiblv be used as a means for crossing the hardy ones in 
order to get similar bold habit, and also hardiness. The species 
under notice is a native of Australia, from whence it was 
introduced in 1852, but, although it has been cultivated more 
or less continuously all that time, it has never become very 
common in this country, ow’ing, possibly, to its being con¬ 
sidered tender and difficult to flower. We hope, however, that 
improvement having been once commenced by Mr. Hudson, it 
will be continued by other cultivators. 
Cordyalis tomentosa. 
During the past few years some very interesting new species 
of Ccuydalis have been collected by Mr. E. H. Wilson for 
Messrs. James Yeitch and Sons, Ltd., Chelsea. We havei on 
several occasions described the appearance and usefulness of C. 
thalictrifolia ; but on this occasion we describe another new 
species of totally different habit, and which we hope will prove 
as hardy as the now better known species. 
Our illustration was taken at Kew* in March last, where the 
specimen had been sent by Messrs. Yeitch for determination. 
The leaves are bipinnatisect, with obovate or wedge-shaped seg¬ 
ments, covered with a white tomentum, which gives them a 
very distinct appearance from those of any other specie® we 
have seen in cultivation. These leaves are all produced in a 
rosette from the crown of the plant, and spread flat, upon the 
ground. The specimen photographed was, of course, in a, pot, 
but since then young plants have been placed on the rockery 
amongst stones, and the leaves retain the same procumbent 
habit, so that, we think it will make, an excellent rock plant, 
provided it, is, hardy' enough to, withstand our winter. 
Numerous scapes arise from the crown of the rootstock, 
attaining a, length of 6in., and flowering almost, from the 
ground line to the apex. The scape and bracts, like the leaves, 
are also covered with a white tomentum, while the flowers 
themselves are clear, light, yellow, and very pretty. Alto¬ 
gether the habit of the plant i® distinct from anything we have 
seen in the genus as far as garden plants are concerned. It, 
was collected by Mr. Wilson in Western China,, and flowered 
this year for the first time, being quite new to botanical science. 
The Best Flowering Plants at Kew. 
“There are more plants in the garden than ye wot of.” 
Cattleya velutina. 
The distinctiveness of this Orchid is not its only recommen¬ 
dation, as its flowers possess a sweet fragrance and have a 
beauty of their own sufficiently marked to rank this as a 
desirable plant. Its orange-coloured sepals and petals are 
streaked and spotted with purple, and the lip, which is of a 
similar colour a,t the, base, is white, with violet veins in front. 
Brazil. 
Oncidium kramerianum. 
With 0. Papilio and 0. Limminghei, this species forms a 
well-defined group of Oncids, distinguished by the production of 
their flowers, by successive elongation of the rachis. To the 
Butterfly Orchid (0. Papilio) this has a close resemblance, dif¬ 
fering by its shorter leaves, smaller and more orbicular pseudo- 
bulbs, shorter upper sepal and petals, and by the apical lobe of 
the lip being of a brighter hue. The terete stems and thickened 
ring at the nodes are the most constant distinctions. A large, 
handsome flowered species, which is always admired, and 
should find a, place in every collection. 
Dendrobium Phalaenopsis. 
The richest, gem of Australian Orchids, and the finest of the 
Specioeae section of the genus. This species is an ornamental 
and useful plant of easy culture, produces at its apex a long 
arching 6 to 10 flowered raceme of rosy purple flowers, each 
about, 3 in. diameter, having a maroon-purple coloured lip. 
New Guinea, 
Erica Hartnelli. 
One of the greenhouse forms, distinguished by the possession

AND FELTED GRAY LEAVES. 
of a whorled terminal inflorescence, and whorls of leaves 
densely inserted. As a, pot plant, 18 in. high, it has a neat 
appearance, being of erect habit, with short, jointed growth, and 
by the conspicuous ciliation on its leaves. Its large purple 
viscid flowers are nearly tubular, rather swollen at base. 
Costus speciosns. 
A handsome herbaceous perennial, which, for its successful 
cultivation requires a, high, moist temperature. Grown in 
large pans, as a specimen stove plant, it is very effective when 
its simple, soft, cane-like, leafy stems are bearing flowers. The 
terminally produced flowers are white, having a funnel-shaped 
tube and three parted limb, the margins of which are fringed 
and waved, and the inner segment, or labellum, bell-shaped. 
India. 
Hedychium gardnerianum. 
A handsome plant, in habit closely resembling the above, 
but flowering freely in a cool greenhouse temperature. It 
would prove serviceable in the formation of groups at autumn
