44 THE ORCHID REVIEW. [JANUARY, 1916. 
crossed with C. insigne Sander gave the yellow C. San-Actzeus, and this 
-again united with C. insigne Sandere gave C. Sanacdere, another fine 
“yellow form. C.insigne Sanderz, on the whole, has been disappointing as 
a parent, owing to reversion, but crossed with C. Fairrieanum it gave C. 
Arthurianum var. Sanderz, in which the markings are decidedly yellow, 
‘producing a very pretty effect. And at.the last R.H.S. meeting Messrs. 
Charlesworth & Co. exhibited C. Marica (aureum Surprise X insigne 
‘Sandere), a fine yellow hybrid, which is described at page 19. On the 
other hand, C. insigne Sanderianum crossed with C. Maudiz gave a batch 
_ -of seedlings entirely without brown spots, namely C. Rossetti (O.R., xvi. 
p-. 265, fig. 34), and the result came as a surprise, because C. insigne 
‘Sandere X Maudiz had previously given coloured seedlings. - 
Some improved forms of existing hybrids have resulted from the use of 
the fine C. insigne Harefield Hall var. as a parent, for example, C. Arthur- 
danum langleyense, but we will not enumerate them, as enough has been 
said to show how, in the main, the race of winter-blooming Cypripediums 
thas been produced. Other hybrids might have been included, but they are 
either less common or less strictly winter-bloomers, the latter character 
-chiefly due to the influence of summer-blooming kinds in the ancestry, 
Of the majority, C. insigne is in some way concerned in the parentage, 
‘which at once accounts for the ease with which they can be grown, the 
‘time of blooming, and the predominance of green and brown in the 
-colouration of the flowers. It is in the latter respect that there is most 
room for improvement, and we have little doubt that this is gradually 
being effected by continued hybridisation and selection. We invite 
‘suggestions as to the lines on which such improvements might most usefully 
ibe attempted. 
ORCHIDS AT THE PANAMA EXHIBITION.—It will interest Orchid lovers 
to know that the Philippine collection of Orchids exhibited by the 
Philippine Government at the. Panama-Pacific International Exhibition, 
‘San Francisco, California, has been awarded the Grand Prize, the highest 
-award, by the superior jury of the Exhibition. I may state that about ten 
million people have visited the Orchid house, which has been a great centre 
-of interest, as people have been able to see the plants in the growing stages. 
We have had a good display of flower all the time, and there has never 
been less than 250 plants in bloom, so there has always been something of 
interest for visitors to see. I may add that the collection is to be sold at 
‘the close of the Exhibition —W. E. EGLincTon. 
[It will be remembered that a group of Orchids at the Panama 
Exhibition was illustrated at page 105 of our last volume, where also may 
‘be seen a photograph of Mr. Eglington and his assistant.—Ep.]
