AISTORY OF ORCHID HYBRIDISATION. XIX. 
The year 1904 produced a sensational hybrid when the six-flowered 
inflorescence of Odontioda X Vuylstekez appeared at the Temple Show, 
and received both a First-class Certificate and a Silver-gilt Lindley Medal. 
It was raised by M. Charles Vuylsteke, of Ghent, from Cochlioda 
Neetzliana and Odontoglossum nobile (Pescatorei), and is figured at page 281. 
Other interesting hybrids of the year were the beautiful albino Cattleya 
x Peetersie, raised by M. Peeters, of Brussels, from C. Gaskelliana alba X 
C. Warneri alba, Sophrocattleya x Doris, raised by Messrs. William Bull 
& Sons, from S. grandiflora and C. Dowiana aurea, and S.-c. * Atreus, by 
Messrs. Veitch, from S. grandiflora and C. Lawrenceana. 
In 1905 three new generic hybrids appeared. Dialelia x Veitchii was 
raised by Messrs. James Veitch & Sons, from Diacrium bicornutum and 
Lela cinnabarina, and received a Botanical Certificate from the Scientific 
committee of the R.H.S. in the spring of the year. It was described as 
most resembling the Diacrium in habit, as well as in the colour of the 
flowers. 
* Odontioda xX Lairesseze was raised by M. A. de Lairesse, of Liége, 
Belgium, from Odontoglossum crispum crossed with the pollen of Miltonia 
Warscewiczii, and received an Award of Merit from the R.H.S. on July 
zoth, 1905. It is most like the pollen parent in habit, as well asin the 
colour of the flowers, which, however, are larger and modified in shape. It 
is figured on page 217. 
Epidiacrium X gattonense is a hybrid raised in the collection of 
Jeremiah Colman, Esq., Gatton Park, Reigate, from Diacrium bicornutum 
and Epidendrum radicans. It was described as most like a dwarf form of 
the latter, and bearing a terminal head of reddish scarlet flowers. It was 
exhibited without a name on May 9th, 1905. 
The genus Promenza was also added to the list in 1905, a seedling from 
P. stapleioides ? and P. xanthina g having flowered in the collection of 
De Barri Crawshay, Esq., Rosefield, Sevenoaks, which received an Award 
of Merit from the R.H.S. in May, 1905, under the name of P. x 
Crawshayana. It is now believed to be a form of the natural hybrid P. x 
Rollissoni. 
The first two hybrids of Odontoglossum Edwardii were also recorded, 
namely O. X Lairessei, raised by M. A. de Lairesse, of Liége, from O. 
Cervantesii @ and O. Edward #, and Q: x» Thompsonianum, which 
flowered in the collection of W. Thompson, Esq., of Stone, and received 
4 First-class Certificate fromthe R.A.S.;, irom-O; Edwardiu ? and O. 
crispum ¢. This, however, was raised in the collection of D. B. Rappart, 
Esq., of Liscard. 
A handsome hybrid from O. Rossi crossed with the pollen of O. x 
spectabile flowered in 1905 with Messrs. Charlesworth & Co., and received
