212 THE ORCHID REVIEW. [JuLy, 1910. 
own pollen, or possibly by Anguloa Clowesii. This implies a doubt as to 
the presence of Lycaste, a doubt which we do not share, though we have 
suggested that Lycaste cruenta (not L. Skinneri) was the pollen parent, for 
the colour agrees closely, while the crest and markings of the lip are almost 
identical. A hybrid from L. Skinneri should have been very different in 
colour. The figure shows very clearly the influence of Lycaste, but we 
think that Auguloa Ruckeri and Lycaste cruenta were the parents. These 
records suggest the desirability of further experiments, apart from the fact 
that Angulocaste Bievreana is a very handsome plant. As to the insect 
which fertilises the flowers of Anguloas in a wild state, we should much like 
to have the observations of anyone who has seen the plants flowering in 
their native homes.—ED. |

ODONTOGLOSSUM x ANDERSONIANUM. 
I HAVE several times expressed the wish that someone would raise a batch 
of seedlings between Odontoglossum crispum and gloriosum, to see how far 
they agree with the polymorphic natural hybrid O. x Andersonianum, and 
it would now appear that the cross has been successfully made. At the 
R.H.S. meeting held on April 19th last two seedling Odontoglossums were 
exhibited from the collection of A. Harrison, Esq., Lyndhurst, Watford, 
with the records ‘‘O. Pescatorei X Hallii”’ and ‘‘O.crispum X gloriosum.” 
Both were evidently correct, and the latter was clearly a form of O. xX 
Andersonianum. They had been purchased as seedlings with the record 
given, and Mr. Harrison kindly gave me a flower of the latter and under- 
took to obtain its history. He afterwards wrote that it was purchased as an 
unflowered seedling Odontoglossum from Mr. W. B. Kettle, a local 
nurseryman, in 1903, who had bought it amongst a dozen others, in Igot, 
from Mr. J. F. Ebner’s collection, Woodlands, as seedlings raised by Mr. 
Ebner. The plant exhibited may be described as a typical O. X 
Andersonianum, with ivory white flowers of good shape, and bearing three 
or four dull purple spots on the lower half of the sepals, and a similar 
number in front of the crest of the lip, while the crest, basal markings and 
column wings are about typical. The petals are unspotted. It is 
particularly interesting to have the origin of this, the first natural hybrid 
Odontoglossum known, proved by direct experiment, and we should be glad 
to know if any other seedlings have been raised, as these might throw light 
on the remarkable polymorphism of O.  Andersonianum, a plant whose 
history has already been given in detail (O.R., i. pp. 170-174). It has long 
been supposed that some of the forms that have been included under O. X 
Andersonianum are the result of re-crossing with the original species, and a 
batch of seedlings of known ancestry should be instructive.
