are united in different proportions, when it will be impossible to ascertain 
their origin without the actual record, even if this is not already the case. 
A similar condition of things is at least suspected among natural hybrids, 
so that we hope hybridists will preserve careful records of their crosses, and 
thus enlighten us further as to what is taking place in nature. 
ORCHIDS AT ROSEFIELD, SEVENOAKS. 
Ir is interesting to watch the progress being made in the raising of 
‘Odontoglossums, and with this end in view we went down, early in April, 
to see the well-known collection of De Barri Crawshay, Esq., Rosefield, 
‘Sevenoaks, where so many interesting experiments have been made. The 
seedlings, of which particulars have already been given (O.R. xii. pp. 203- 
208), are rapidly becoming the prominent feature of the collection, the work 
in hand being everywhere apparent—numerous capsules, germinating seed- 
lings in various stages on the pots of the parent plants, and hundreds of 
‘others steadily progressing towards the flowering stage. One interesting 
novelty was just expanding, being a seedling from O. Harryanum and O 
Hunnewellianum, of which a description was given at page 157, under the 
name of O. X Iago. O. X Terpsichore is another very pretty hybrid 
raised in the collection, between O. Pescatorei and O. polyxanthum, of 
which forms were in flower, both with white and yellow ground colour. A 
form of O. X Harryano-triumphans bore a spike of eight very large and 
richly-coloured flowers, the seed parent being O. Harryanum. Three pretty 
forms of O. xX Fascinator raised in the collection were also in flower, and 
the curious seedling from O. crispum crossed with O. X Wilckeanum, 
which has reverted to a quite unspotted form. 
Mr. Crawshay pointed out a nice little batch of Odoritioda x Vuyl- 
‘stekez, some of which were making their third bulb, and may begin to 
flower next year. He hasa lot of other Cochlioda Neetzliana crosses, but 
a curious thing which he remarked is that this species can only be used as 
the seed parent, as all attempts to use the pollen on Odontoglossums have 
resulted in failure. It is a good seed parent, and one plant bearing four 
and another two capsules were pointed out. About forty crosses with it 
were attempted last year. Odontoglossum Edwardii behaves in a similar 
‘way, and has only succeeded as the seed parent. 
Seed-bearing is not considered injurious when plants are strong and 
well-rooted, in proof of which a plant of O. crispum was pointed out 
bearing two large capsules and a strong spike of ten buds, without any 
apparent diminution in vigour. A plant of O. X Queen Alexandra also 
carried a pod and a fine spike, while one of O. Harryanum carrying a pod 
‘was equally vigorous, and the list could be much prolonged, for numerous 
plants were bearing capsules. There are many strong specimen plants in
