114 THE ORCHID REVIEW. 
the colour alone being modified, but, so far as I know, all forms of CO. x 
Wilckeanum show distinct traces of O. luteopurpureum in shape. What a 
secondary hybrid derived from O. crispum again crossed with O. X 
Wilckeanum would be like can only be approximately inferred, but I should 
be surprised if it gave the brilliant colour of the present one. Now that O.X 
Wilckeanum has been artificially raised, as well as other Odontoglossums, 
it would be interesting if someone would attempt the above-suggested cross, 
for the result could not fail to be very instructive and interesting.

THE RAISING OF ORCHID SEEDLINGS. 
By R. EICHEL, Bradford. 
(Continued from page 8&4.) 
THE erect growing varieties of Epidendrum are easily raised from seed ; 
Wallisii, radicans, and Endresii have produced hybrids, which probably may 
have a great future in store, if they can be induced to cross with Lzlias and 
Cattleyas, a problem which is now being experimented upon. The charm- 
ing bigeneric hybrid Epiphronitis Xx Veitchii has opened the eyes of 
hybridists, and is, doubtless, in no small measure responsible for the 
experiments which are being made in various collections. Epidendrum 
Wallisii is a very good producer of hybrids, one of the offspring, X Endresio- 
Wallisii, has been used again as pollen parent, and produced the much 
admired E. X elegantulum. E. Frederici-Gulielmi is another species which 
can be highly recommended ; the free growing habit of the plant, together 
with its floriferousness, cannot fail to attract attention. 
Epidendrum vitellinum is a subject of very great importance, the 
beautiful colour is a matter of no small consideration, though I confess the 
flowers are most difficult to fertilise, and the seed still more difficult to 
raise. Eighteen months ago Mr. G. Marchetti, Manor Heath, Halifax, 
obtained a seed-pod of E. vitellinum crossed with Odontoglossum crispum. 
I examined the seed very carefully with a powerful magnifying glass, and 
found a large percentage of good seed, which, being sown in various ways 
and under various conditions, appeared to go on well. Two months later I 
Saw the seed again, some of them swelling beautifully and turning green. I 
am afraid, however, that since the collection has been dispersed Mr. 
Marchetti has not taken the same keen interest in them as formerly. This 
cross interested me very much, and the facts are well worth recording ; 
though it would have pleased me more to record the flowering of such an 
extraordinary mule.
