Cattkya intermedia) a plant which, until 
recently, was referred to Cattleya and Liclia. 
It was brought from Brazil in 1857 and has 
recently been nearly reproduced in gardens in 
Brassocattleya x nivalis {B. Jragrans, or pos- 
sibly tul^ercu/ata x Cattkya intermedia). Both 
plants have the same habit of growth and form 
of flower, but in the natural hybrid the broad 
concave lobe of the lip is white tinged and 
spotted with purple, whereas in nivalis the 
purple colouring is absent. 
Brassocattleya x striata is a home-raised 
hybrid between Cattleya Mossice and Brassa- 
vola fragrans tuber cu lata)., with, showy, ex- 
panded, rose-veined lip. 
Brassocattleya x Belairensis [B. Perrinii x 
Cattleya guttata) is a continental hybrid, with 
prettily formed flowers of rather thick sub- 
stance. 
Brassocatlcelia x Mackayi {Lcelio-Cattleya x 
elegans x Brassavola Digbyana) is a pretty 
hybrid with blush-pink flowers, the fringed 
lip being rosy-pink colour. 
Brassocatlalia x Lindleyano-elegans is the re- 
sult of crossing Brassocattleya x Lindleyana and 
Lceliocattleya x elegans. 
Brassocattleya x Orpheus [B. glauca x C. 
Trianai alba) is a very pretty white hybrid 
with fragrant flowers, first bloomed in January 
1902. 
Brassocattleya x Sanderi {B. glauca x C. 
Schrodera) flowers similar to those of Orpheus.

A Winter-blooming Tree [Prunus Davidi- 
ana alba). — Mr Waterer sends us beautiful 
sprays of this in mid February, sprays which 
surprise us by their extraordinary beauty, every 
twig being laden with pure-white flowers or 
pearl-like buds. It is seldom that a white 
form is prettier than the usual form of a tree, 
but in this case we may almost claim that it is 
so. As in nine out of ten winters we may hope 
that the weather will be favourable enough to 
allow this tree to bloom over a large range of 
our country, it will be seen what a very im- 
portant hardy tree it is, and how it lends itself 
to fine effect in the open. It is also one of those 
things that serve so well for cutting for the 
house before it opens naturally, thus prolong- 
ing its bloom-time. 
NEWER WILD TULIPS.* 
Upon the opening up of Central Asia 
by the Russians, some thirty years ago, 
quite a large number of new Tulips 
were introduced into our gardens. Of 
these such noble species as Tulipa Grei- 
g^j Kau/mannmnay Ostrowskyanay and 
others, have now become fairly well 
known, and where these find a suitable 
home they create an effect that no other 
Tulips can approach. There is a pecu- 
liar brilliancy in the flaming orange- 
scarlet of Greigi and Ostrowskyana^ and 
what other Tulip possesses the exquisite 
Water-lily shape of the long-pointed 
flower of Kaufma?i?iia72a } In a good 
many gardens Greig's and Kaufmann's 
Tulips are now well established. Deep 
planting, so that the sprouts may not 
appear too early, seems to be one of 
the great essentials to their welfare. In 
view of these gains it was a matter of 
deep regret when further supplies were 
cut off by the death of Dr. Regel, who 
had brought these and many other new 
Tulips into cultivation. That there were 
yet other good kinds awaiting us in the 
heartofAsiawasa matter of little doubt, 
and a series of botanical expeditions to 
these far-off regions was therefore organ- 
ised by Mr. C. G. van Tubergen of 
Haarlem, expeditions which have been 
continued up to the present time. These 
have been the means of adding other 
remarkable plants to this brilliant genus, 
among which the following are perhaps 
the most notable. 
Tulipa JVilsoniana. — A Tulip of highly 
finished appearance, found by Sintenis in 
1 90 1, when travelling in Turan some distance 
east of Aschabad. The foliage is narrow, re- 
minding one of the peculiar leaves of T. lini- 
With a coloured plate of Ttilipa Tuber geniana, from a drawing by Miss E. Williamson.
