ees | -ODONTOGLOSSUM PRAEVISUM. Eee] 
A interesting hybrid Odontoglossum, raised from O. Lindleyanum 
crossed with pollen from O. gloriosum, is now flowering at Kew for 
the first time. Thecross was made by the writer with the object of proving 
the parentage of a wild hybrid which flowered in the collection of 
W. Thompson, Esq., Walton Grange, Stone, in April, 1904, when it was 
forwarded by Mr. Stevens with the suggestion that it might be a natural 
hybrid between O. Lindleyanum and O. gloriosum or O. Andersonianum. 
It was then described as O. previsum (O.R., xii. p. 176), the name 
suggesting that its appearance had been foreseen. Eleven years earlier, 
when dealing with the natural hybrids from the O. crispum district, it was 
pointed out that five out of the six possible combinations were already 
known, while the appearance of the remaining one, between O. gloriosum 
and Lindleyanum, among the importations from the district, might be 
anticipated (O.R., i. p. 277). Mr. Thompson’s plant had very acuminate 
sepals and petals, spotted and blotched with light reddish brown on a 
yellowish white ground, while the influence of O. Lindleyanum was seen in 
the details of the column.. The Kew plant is much brighter yellow, and 
the petals, especially, are densely dotted and lined on the lower half with 
brown, while there is a bright red-brown blotch on the lip in front of the 
very prominent crest, and the elongated column has long cirrhate wings. 
It combines well the characters of the two parents, and at its initial 
attempts has produced a panicle of 22 flowers. It closely resembles 
O. Leeanum, Rchb. f., in colour, but has less acuminate segments, which 
raises a question as to the parentage of the latter. This appeared as a 
unique plant in the establishment of Messrs. James Veitch & Sons, and its 
origin was not stated, but Reichenbach compared it with his O. delto- 
glossum, except in its larger lip and distinct colour. When afterwards it 
was figured in the Botanical Magazine (t. 8142) I suggested O. gloriosum 
and triumphans as the parents, for it is clearly distinct from O. Ander- 
sonianum, with which previously it had been associated. The variation of 
hybrids is notorious, and the question now remains whether the three 
mentioned are forms of one. It may be added that other plants of the 
batch of O. Lindleyanum x crispum (O.R., xxi. p. 175) have bloomed, the 
latest being almost the exact ‘match of an O. Coradinei figured by 
Mr. Day. It proves again that the facts cannot always be cleared 
up by the flowering of a single seedling, and that variation is not 
limited to secondary hybrids. The first seedling was more like O. 
Lindleyanum.
