he new variety which we now figure flowered early this year at 
Moortebeek, and has been dedicated to the devoted Treasurer of the 
hin OrcHinEENNE, Mr. pu Trizu pe TERDONCK, one of the most capable of 
Belgian amateurs. It may be considered as representing the apogee of the 
beauty of this highly esteemed Bornean species. The upper sepal particularly 
is exceptionally large and remarkably coloured, the red stripes with which it 
is decorated being prolonged to the apex and anastomosing among themselves 
at several points. The petals are very long, and the lip is of a deeper colour 
than usual. 
In an article published some years ago in the Journal des Orchidées, the 
following observations concerning the climate of Borneo occur : 
“ What characterises the habitat of Orchids in tropical regions, and 
particularly in the Dutch Indies, is not, as one would imagine, a burning 
Fata ee 8 
& 
sun and a certain dryness of the soil. Most of the species, on the contrary, 
grow in a very close atmosphere, shaded from the rays of the sun, and 
“ plunged in a vapour bath constantly maintained by the long and continued 
evaporation from pools of rain-water or springs. The temperature is very 
“ high in these places, which are seldom penetrated by the sun, and the air 
“ ig disturbed but little owing to the accumulation of vast heaps of leaves; the 
“ sun dries very slowly, and the rising vapour remains stationary for a long 
“ time in this stove-like atmosphere. , 
In spite of the enormous differences existing between these conditions of 
life and those under which Orchids in Europe are grown, Cypripedium Lawren- 
ceanum thrives remarkably well in cultivation, develops rapidly, and flowers 
profusely every year. It is one of the most characteristic examples of flexibility 
of temperament, and of the marvellous faculty of adaptation possessed by these 
beautiful plants.
