216 THE ORCHID REVIEW. (JULY, 1923. 
(C. Mossie X Le. G. S. Ball), with a spike of several medium-sized flowers 
of a charming apricot colour, came in for its due share of appreciation. 
Messrs. Armstrong & Brown staged a remarkably fine specimen of 
Dendrobium acuminatum, to which Cultural Commendation was given, 
and also the handsome Odontoglossum Victory var. Supreme, with three 
immense flowers having the segments blotched with red-purple. 
J. J. Bolton, Esq., Claygate, Surrey (gr. Mr. S. Lyne), exhibited his 
beautiful variety of Brassoleliocattleya Jupiter, with two flowers each 
measuring ten inches across.. 
ODONTONIA OLIVIA. 
4N URING the last ten years the cool growing section of Orchids has been 
enlarged by the creation of hybrids between Miltonias and Odonto- 
glossums. Their generic name Odontonia is thus well formed. The number 
of these elegant crosses now totals 25. To the amateur there is in almost 
all genera one particular organ that stands out prominently and appeals to 
him on account of its attractive qualities ; in Odontoglossum it is the broad 
petals ; in Miltonia the expansive labellum. 
The majority of Odontonias have Miltonia Bleuana (vexillaria x Roezlii) 
as one of their parents, for when making use of this large-flowering plant 
the hybridists hoped that its expansive labellum would be perpetuated in 
the following generation. This anticipation has been realised to a favour- 
able extent, for not only have several very distinct novelties been produced, 
but a section of hybrids has been raised that can be grown with success in 
an atmosphere which is generally a little too warm for Odontoglossums, as 
occurs in many localities in the United States of America. 
Our illustration is of Odontonia Olivia, the result of crossing Miltonia 
Bleuana with Odontoglossum triumphans var. Crawshayanum. It was 
exhibited by Messrs. Charlesworth & Co. in their superb group at the recent 
Chelsea Show, when an Award of Merit was granted. The flowers were 
much larger than seen in the photograph, and had lost some of their beauty, 
for nearly seven weeks had elapsed between the time of their first opening 
and the R.H.S. Committee’s award. When at their best the ground colour 
was bright golden-yellow and the blotches light chestnut-red, the contrast 
being very marked. One can well imagine the fine effect that will be 
produced by this plant when grown into a specimen with a dozen or more 
spikes of flowers arranged gracefully around it. The Chelsea Shows of the 
future will surely contain such specimens, and when they do appear there 
will be heard the remark: “ Ah! most beautiful, and I can remember the 
time when they first appeared with single spikes of four or five flowers.” 
We thank the Editor of the Gardeners’ Chronicle for kindly lending the
