THE ORCHID WORLD. 
[February, 1913. 
Then as regards the crossing of Wilcke- 
anum with phmi crispum, I think the propor- 
tion of white woukl be more than one in 
four, because it is sometimes greater than 
tlvat when a blotched crispum is used. As 
I said in the discussion of the Paper, the 
m(irtahty among the seeds and infantile 
plants IS a very disturbing factor in all these 
calculations, and I do not see how it can 
be obviated or reduced to an absolute 
proportion of various forms. 
Take a parallel cross in Odontoglossum 
amabile, which bears the same analogy m its 
descent from Harryanum as mirum does from 
luteopurpureum, I do not think the proportion 
of one blotched and one plain of both yellow 
and white grounds has been at all proved. 
Personally I have bloomed a great many 
plants of amabile, but have never \et had 
a plain white or a plain )'ellow one (I wish 
I could get a well-formed one, it would be 
worth having), and as far as I hear from 
other raisers I have no knowledge of one, 
Here, I think, we have a strong point against 
the arithmetical proportions of the Mendelian 
theory in these complex hybrids. 
There are five different possible ways in 
Nature's workshop of making a blotched 
crispum, as she could have produced them 
with the aid of luteopurpureum, gloriosum, 
and Lindleyanum, from the old Pacho 
districts, and with triumphans and Hunne- 
welhanum from the newer Chiqumquira 
habitats. 1 use these terms geographically 
to indicate the two great divisions of Odonto- 
glossum crispum. 
The hybridist has raised crispums from 
plants containing all these five species in 
their ancestry, and the resulting seedlings 
in many cases unmistakably prove their 
influence. By far the greatest number of 
blotched crispums emanated from the districts 
where Hunnewellianum grows mixed with 
crispum, while those resulting from the 
habitats containing luteopurpureum were 
quite a few compared to these later intro- 
duced forms. 
Tt has been proved rzr/-)' /hue that mij' 
pair of blotched imported crispums v»'ill throw a 
large quantit\- of nnspf>tted forms. Therefore, 
I can hardly think that Franz Masereel, 
Leonard Perfect, Lindenii, Victoria Regina, 
Rossendale, Lucianii, Alphonso, and Craw- 
shayanum all result from a cross between a 
blotched and white form as is presumed by 
Major Hurst. 
The result of crossing two seedling blotched 
crispums has yet to be seen, and according 
to the laws Mendelian the results should be 
all blotched. I hope it will prove true, but 
I fear it will not be so by a long way, for if 
we could raise such fine things as King 
George V., St. Fuscien, and others of the 
first rank, in quantity, it would be a decidedly 
pleasant thing to liave achieved. 
Major Hurst appears to consider the 
blotched character of a crispum should be 
permanently fixed in three generations. I 
sincerely hope he is correct and that I am 
the reverse, but I fear even the third crossing 
will give a lot of reversion to plain, unspotted 
forms. 
The Making of a Scarlet 
Crispum. 
Major Hurst thinks we have been slow 
herein, but he knows that Nature does not 
do just all we think she ought to do at our 
bidding. In some of the latest Odontiodas 
we are getting near the size of a crispum, 
but as yet we have not eliminated the 
blotching on the red ground of the largest 
derived from crispum and Pescatorei. Doubt- 
less there are many seedlings growing now, 
the result of unspotted crispums crossed with 
Cochlioda Nnezliana, and in due time these 
will tell if this is the way to produce the 
.Scarlet crispum. 
The only one that I know thus crossed is 
Odontioda Bradshawias Cookson's var., which 
Mr. Chapman states was raised from a fine 
unspotted crispum, but it is by no means a 
pure scarlet crispum, as there is a great deal 
of lilac in it, almost violet ; of course, there 
ma}' have been a gocd deal of purple sap in 
the crispum used. 
Regarding the crimson crispum and Major 
Hurst's way of producing it, I may state that 
Odontioda rosefieldiensis (C. N. x triumphans
