dontoglossum Bergmani was exhibited for the first time at the twenty-seventh 
meeting of the Qrchidéenne, of Brussels, on the 12 th. of April 1891, 
when it was unanimously awarded a First-class Certificate of Merit. 
diibited by M. F. Bergman, Superintendent of Culture of the estate of 
Ferrières-en-Brie, near Paris, well known to ail horticulturists for the splendid 
results wbich be bas obtained in tbis superb estate, and was dedicated to bim 
during the meeting as a souvenir of the glorious reunion at which M. Bergman 
was présent, and the great success obtained by the remarkable Orchid which 
he exhibited. 
O. Bergmani is, indeed, a form of the first rank. It belongs to a vast group 
which it is agreed to call natural hybrids, but it deserves a place apart in the 
group by reason of the grandeur and the élégant colour of its flowers. The plant 
exhibited at Brussels bore two inflorescences, of large size, carrying sixteen 
flowers, which measured not less than four inches in diameter. The segments, 
very broad, distinctly fusiform, and lightly fringed on the margins, were of a 
beautiful white colour with some large spots of clear chocolate-brown. 
In habit O. Bergmani is very near O. luteo-purpureum , of which it has nearly 
the leaves, and we think that perhaps it may be considered as a white form of 
tbis very variable species. It has very large and very strong pseudobulbs, and 
is in appearance one of the giants of the group. 
Its culture is not sensibly different from other Orchids of the section. It 
succeeds perfectly, as we hâve already pointed out, cultivated in the cool house 
in a mixture of nearly equal parts of fibrous peat and sphagnum. The atmosphère 
of the house should be very cool and moist; in summer care should be taken to 
give ail the air possible, and to keep down the température by frequent sprink- 
îings, not only of the pots, but also of the tables and paths. 
Growth is very active from February to December, and diminishes during 
the coldest of the winter months, but without a decided period of rest, as in 
most other généra. It should, however, be possible, as indicated in the Journal des
