to Colombia, fully equipped as an Orchid 
collector. Hi.s consignments included a very 
fine type of Odontogiossum crispum, which 
he hunted up after considerable difficulty ; a 
hne lot of Od. Pescatorei ; Cattleya Trianse ; 
a good form of C. Mendelii ; a splendid type 
of C. gigas, from which have flowered several 
Hardyanas, one of which had white sepals 
and petals ; Miltonia vexillaria and M. Roezlii. 
His best expedition was undertaken two 
years ago when he went to Antioquia and 
sent home one of the finest lots of Cattleya 
aurea ever seen. On various occasions he 
discovered rare and unknown species, many 
of which on flowering may probably prove to 
be new, and he carefully noted the conditions 
and surroundings of the plants' natural home. 
Ryall encountered many terrible experiences, 
including the loss of an eye, and although his 
fearless spirit and strong constitution ren- 
dered him particularly fit for his arduous and 
risky duties, he died on board ship and was 
buried at sea when within three days' journey 
of England.

Unexpected Colour. — As the progres- 
sive work of the hybridist proceeds with 
astonishing rapidity and the recording of new- 
crosses IS almost of daily event, we frequentl)' 
receive unexpected surprises in the different 
colours produced by a new combination or 
arrangement of the pigments derived from 
the parental flowers. As an example we may 
instance the recently raised Odontioda Made- 
line (Odontioda Charlesworthii x Odonto- 
glossum crispum), several of which have 
flowers with distinct yellow and orange 
colours. All the forms of Odontioda Charles- 
worthii, without exception, have rich crimson- 
red flowers, and, at first sight, it is somewhat 
perplexing to account for a yellow or orange 
flower being produced from a combination of 
this hybrid and the white flowering Odonto- 
glossum crispum. Closer examination, how- 
ever, of the Odontioda Charlesworthii reveals 
a certain amount of yellow, especially on the 
back, and it is quite possible that m the 
formation of the resulting hybrid, a re- 
arrangement of the cells takes place, and 
those containing the yellow ijigmcnt arc 
brought to the surface. Professor Weisniann, 
in his " Germ-Plasm," has stated : " If the 
yellow and red of two different species were 
blended m the flower of a hybrid, the 
intensity of both these colours might con- 
ceivably be as great as in the parent plant, 
and yet one of them might predominate 
because it happened to cover the other." 
Mr. A. E. Bunyard has shown how, in a 
section of a petal, these two colours, yellow 
and red, may be associated in separate but 
adjoining cell layers in definite patches, and 
in such a fashion that, when both were 
exactly superimposed, a very intense colour 
appeared ; while a less exact coincidence 
would allow the lighter tint to appear between 
the darker one, and in this way produce 
more or less marked graduations of tint.

Albinism. — Messrs. Sander and Sons have 
had some interesting results from a batch of 
hybrids produced by crossing Laelio-Cattleya 
Myra (L. flava x C. Trianas) with C. Triana?. 
The latter parent had pure white sepals and 
petals, and a slightly coloured lip. One seed- 
ling has given bright golden-yellow flowers of 
medium size, and another has produced larger 
flowers with pure Vi'hite sepals and petals, and a 
slight tint on the front lobe of the lip ; in fact, 
it much resembles the Trianas parent, but the 
habit of the plant clearly shows the influence 
of the flava species. The combination of the 
yellow and light purple appears to have pro- 
duced an albino form, which is worthy of note, 
and gives support to the theory recently put 
forth by Mr. Richard G. Thwaites that albino 
flowers may be produced in this wa)'. 
ORCHIDS AT BRUNOY, FRANCE. 
Monsieur Chas. Maron, Brunoy, France, 
has raised a considerable number of Orchid 
hybrids ; m fact, he was one of the earliest to 
take a special interest in Brassavola hybrids. 
Sev eral of his productions were well shown 
at the recent International Exhibition, held at 
\oi.. 
in.
