THE ORCHID REVIEI. 265 
ORCHIDS AT ROSEFIELD, SEVENOAKS, 
AN account of the interesting collection of Orchids grown at Rosefield, 
Sevenoaks, by De Barri Crawshay, Esq., was given at pages 230-234 of our 
first volume, and the following additional notes, taken at a recent visit, 
will probably be read with interest. 
Odontoglossums are one of the features of the collection, and it is 
interesting to note that Mr. Crawshay has twenty-cight seedlings in various 
stages, and representing several different crosses, one of them, from O. 
~apterum (nebulosum) crossed with a heavily blotched form of O. crispum, 
having apparently passed the critical stage, so that unless it meets with 
some unforeseen accident flowers may be expected in due time. Plants of 
O. Rossii carried some good seed-pods, an established plant of O. crispum 
which had ripened two pods had also made a good growth. Mr. 
Crawshay has observed that in order to get good seed-pods the plants 
should be well established, the old bulbs then having their own set of roots. 
Imported bulbs, which have lost their roots, fail to mature the pod. 
Mr. Crawshay’s collection affords some interesting evidence that under 
proper treatment Orchids may be cultivated almost indefinitely, for he still 
has -the first Odontoglossum he ever purchased —a plant of O. 
luteopurpureum, bought as O. crispum Lehmanniin December, 1880, which 
is still healthy and vigorous, as are also two plants of O. crispum purchased 
in 1881. One plant of O. crispum carries healthy foliage on four successive 
years’ growth, and a plant of O. X Coradinei Rosefield variety retains the 
pseudobulbs of twelve successive years’ growth, the longest observed in the 
collection, if not anywhere. Another Odontoglossum forms a curious con- 
trast to this, for the leaves invariably die at the end of the first year, and 
the bulbs only remain two years, and, curiously enough, this plant refuses 
to flower, though it has been in the collection thirteen years, and the 
imported bulbs also had not flowered. It came out a batch of O. crispum, 
mostly poor forms, which produced several hybrids, as this also is suspected 
to be. It may here be noted that Mr. Crawshay never cuts out the old 
bulbs, but leaves them until they dry up, when they are easily removed by 
twisting them round, without damaging the plant. O. Hunnewellianum is 
represented by a plant of the origina! importation, in 1889, and O. nevium 
dates from a much earlier period. 
Among Cattleyas and Lelias many plants could be named which have 
been grown for many years, and among them the handsome form of 
Cattleya Lueddemanniana figured at t. 16 of the first series of Warner's 
‘Select Orchidaceous Plants, under the name of C. Dawsoni, which remains 
healthy and flowers every year. The only plant of Dendrobium Wardianum 
in the collection is in thriving condition, and the old bulbs are removed
