C: rise and development of this brilliant artificial genus is one of the 
wonders of modern horticulture. Less than eleven years ago 
Odontioda Vuylstekee made its first appearance—at the Temple Show, in 
1904, to be exact—and now Odontiodas form one of the leading features at 
our horticultural exhibitions. By the time the Orchid Stud-Book was 
published, four additional hybrids had appeared, and in IgII, when a 
supplementary list was given in these pages, the number of primary hybrids 
had grown to 20, and, what is equally remarkable, no fewer than 23 
secondary hybrids had been recorded. Fourteen of these represent unions 
between Cochlioda and hybrid Odontoglossums, but in nine cases an 
Odontioda had itself been used as a parent, eight being re-crosses with 
Odontoglossum and one with Cochlioda. The latter was Odontioda 
Pixie (Cochlioda vulcanica X Odontioda heatonensis). The number has 
since been greatly augmented, and we may now attempt a summary of the 
THE GENUS ODONTIODA 
results obtained. 
PRIMARY HYBRIDS. 
Seven additional primary hybrids have now been added to the list, six 
of them having been derived from the scarlet Cochlioda Noetzliana :—
