January, 1910.] THE ORCHID REVIEW. ri 
to the receipt of the above communication, one on the same subject was 
transmitted by Alexander Seton, Esq., and read at the Meeting of the Society 
on the 2oth of August, 1822. Mr. Seton had happened to make a similar 
experiment, by impregnating the flowers of the Dwarf Imperial, a well-known 
green variety of the Pea, with the pollen of a white free-growing variety. 
Of the flowers so treated one only produced a pod, and it contained four 
Peas, which did not differ in appearance from the others of the female 
parent.” . . . These seeds were sown, and plants were obtained which 
‘seemed to partake of the nature of both parents.” . . . ‘On their 
ripening it was found that instead of their containing Peas like those of 
either parent, or of an appearance between the two, almost every one of 
them had some Peas of the full green colour of the Dwarf Imperial, and 
others of the whiter colour of that with which it had been impregnated, 
mixed indiscriminately and in undefined numbers ; they were all completely 
either of one colour or the other, none of them having an intermediate tint, 
as Mr. Seton had expected. The representation of one of the pods in Plate 
ix. Fig. 1 conveys a very perfect idea of its appearance.” 
Here is not only ‘‘ Segregation,” but also the so-called ‘*‘ Dominant” 
and ‘“* Recessive ’’ characters, and the coloured figure gives a most graphic 
illustration of the points described. It is probable that Mendel never saw 
this particular paper, which antedates his own by over a period of forty 
years, and we call attention to it chiefly because justice has not been done 
to it, and in the volume recently reviewed in these pages (xvii. pp. 257-263) 
we do not find it even mentioned. 
We now come to our own particular subject, and we find that 
‘‘ segregation” was obseryed, and commented upon very strongly, in the 
case of the very first secondary hybrid Orchid raised, namely, Lzliocattleya 
fausta, which flowered in 1873, and was described under the name of 
Cattleya X fausta. Two quite distinct forms were described and figured 
at the outset, namely the type and variety radicans (Gard. Chron., 1873, pp. 
289, 290), while several other forms appeared later. Several of these were 
figured by Mr. Day (Orch. Draw., xxx. tt. ai, 32; =xux. tt. 3, $5), and in 
1881 Mr. Day wrote :—‘‘ Two more plants of this charming hybrid have 
flowered . . . and they are very different from it and from each other. 
Mr. Seden tells me that they raised seven plants of it only (or that only 
seven had flowered), and they are all different. This he attributes to the fact 
that the pollen parent, Cattleya exoniensis, is itself a hybrid between C. 
Mossiz and Lelia crispa, and some of the offspring have run back to their 
grandparents and some have taken more to their mamma, C. Loddigesii.”’ 
This ‘‘ segregation ’’ manifested itself at the very earliest opportunity, and 
it has been observed and commented upon on countless occasions since. 
Mendel’s method of work was essentially different from that of the
