this high distinction unless satisfied and 
assured that the exhibit is, m the main, due 
to the work and capabiht\' of the exhibitor or 
his employees ; on this point the Council may 
consult any expert not eligible to win the cup, 
and may reserve decision till the third day of 
the show.

Orchid .Sale. — Duplicates from the 
Wilderspool collection formed by Mr. Wm. 
Bolton, of Warrington, were sold by Messrs. 
Protheroe and Morris on March 7th, 1913. 
The following figures are of interest : 
Cypripedium Boltonii, 2 growths, 1 5 gns. ; 
Cattleya gigas Frau Melanie Beyrodt, 4 bulbs, 
7 gns. ; Odontoglossum crispum, fine shape, 
8 gns. ; O. c. Lucianii, I large bulb and new 
growth, 10 gns. ; O. c. The Nyzam, 5 bulbs, 
10 gns. ; Cattleya Hardyana alba, 5 bulbs, 
16 gns. ; and C. Souvenir de Queen Victoria, 
5 bulbs, 22 gns.

Parthenogenesis. — Mr. Wm. Bolton, of 
Warrington, kindly informs us of two other 
instances of supposed parthenogenesis. In 
the first case Dendrobium Wardianum was 
crossed with Dendrobium atro-violaceum, and 
all the seedlings which flowered proved to 
D. Wardianum. The second case was 
Cymbidium insigne crossed with Odonto- 
glossum amabile, and although no seedlings 
have as yet flowered, there is not the slightest 
trace of the Odontoglossum parent in any of 
the plants.

MiLTONIA SPECTABILIS MORELIANA. — 
Since in many collections this magnificent 
Orchid does not thrive, nor flower satis- 
factorily, a few remarks upon a system of 
culture which seems to answer may be of 
interest to readers of the ORCHID WORLD. 
The coolest end of the Cattleya house must be 
utilised, and abundance of light and air are of 
the utmost importance, coupled with careful 
attention to watering, endeavouring to keep 
the compost in an even state of moisture 
throughout the growing season. Only give 
shade when the sun is sufficiently strong 
enough to scorch the leaves. Another point to 
which I attribute much of my success with this 
Orchid is annual re-panning. This seems to 
give much encouragement to the young 
roots, and for compost a mixture of chopped 
osmunda fibre, oak leaves, and sphagnum moss 
has been found most beneficial. A proof of 
how well this system answers may be afforded 
when it may be remarked that one plant is 
now carrying a healthy seed pod, and the same 
bulb is throwing up two new leads as well. 
Three other plants are also carrying seed 
pods. — C. Alwyn Harrison.

BrassO-Cattleya Menda. — The future 
work of the hybridist will be much occupied 
with albino varieties, and, so far, there is 
evidence that considerable success will be 
obtained. Messrs. Hassall and Co., South- 
gate, have produced a beautiful result by 
crossing Cattleya labiata Virginia, an albino 
form of the species, with the white variety of 
Brasso-Cattleya Digbyano-Mossiae known as 
Queen Alexandra. The flowers are of 
splendid substance, pure white, the only 
exception being a purple blotch on the centre 
of the labellum. The shape varies, especially 
in the width of the petals. A very fine variety 
of this hybrid was figured on page 138 of our 
last issue, and it will be interesting to see if 
any coloured forms appear.

Dendrobium Sibyl. — The history of this 
hybrid Dendrobium goes back to March 28th, 
1893, when Mr. N. C. Cookson obtained an 
Award of Merit for a plant he exhibited at the 
Royal Horticultural Society. The parentage 
was given as Linawianum x bigibbum, 
although it was noticed at the time that little, 
if any, trace of the latter parent was visible. 
The following year, on March 13th, a First- 
class Certificate was awarded to Mr. Cookson 
for a plant of the same name and parentage, 
it being again remarked how much the pollen 
parent had been obliterated. About the year 
1903, Mr. T. Armstrong, convinced that the 
stated parentage was incorrect, suggested that 
crassinode might have been used instead of 
bigibbum, and that it was his intention to raise 
a hybrid similar to Sibyl by crossing crassinode 
with Linawianum. Although several years 
elapsed before he could obtain both species in
