116 THE ORCHID REVIEW. [ApRIL, 1913. 
newer the compost the better, in fact he usually sows the seeds 
immediately the plants are potted. He also avoids the use of leaf-mould, 
‘because it harbours the maggot of the fly that is so destructive to Odonto- 
glossum seedlings. They may possibly germinate better with a little leat 
mould in the compost, but his experience is that it is more than counter- 
balanced by an increased loss of the seedlings, and he fumigates regularly 
‘twice a week at seasons when the fly is troublesome. We noticed a lot of 
Pinguicula caudata in flower, and remarked, jokingly, “‘ These are not 
Orchids.” “No,” he replied, ‘‘ they are fly catchers,” and then came the 
information above given. The identity of this fly is apparently not known, 
but Mr. Moss believes it lives naturally in decaying leaves anywhere, and 1s 
brought with the compost into the house, where it becomes troublesome. 
We handled many pots on which the young seedlings were germinating 
freely, in various stages, and we saw also an experiment that is being tried 
of sowing the seeds on canvas, as in the case of Cattleyas, the pots being 
covered with a piece of cardboard. They appeared to be germinating 
freely, but it is a question whether this method would give light enough, in 
which case a piece of glass might be tried. 
As soon as the young seedlings can be handled they are pricked off and 
placed under a hand light until established, there being several glass cases 
in the house for this purpose. Many interesting crosses were pointed out, 
including Odontioda Charlesworthii crossed with O. crispo-Harryanum, 
with O. Pescatorei, and with blotched and white forms of O. crispum ; 
Cochlioda Neetzliana crossed with Odontoglossum Rolfee ; O. Uroskinneri 
crossed with C. Neetzliana, this being the solitary instance in which this 
Cochlioda has been used as the pollen parent. Generally the capsule 
begins to develop and then goes off. Odontoglossum maculatum has been 
successfully used on several occasions. Odontioda Mossiz has just been 
mentioned, and Mr. Moss has flowered O. maculatum x Pescatorei, an 
interesting cross though not of much value, and seedlings were pointed out 
of O. maculatum crossed with both O. Uroskinneri and O. Vuylstekei. O. 
Hallio-crispum X madrense is represented by a good-sized plant, and we 
noted also O. mirificum xX crispum Mossie, O. nevium x crispum, and a 
batch of O. Ossulstonii. O. Adrianz x Pescatorei was in bloom, but was 
an ordinary form, with large dark blotches on the sepals. 
Mr. Moss has a very able lieutenant in the person of Mr. Kench, a keen 
cultivator, who has long presided over the various departments of an 
interesting general garden, where Orchids may be regarded as first 
favourites. Mr. Kench is a keen hybridist, and has a careful record of all 
the crosses made, which Mr. Moss posts up into a book when the seedlings 
are pricked off, and thus there isa complete record of everything raised in the 
collection. Mr. Kench could probably relate some interesting experiences, 
peeks:
