This plant is considered by some authors to be a variety only of an older 
plant, well known and much admired, by the name of Zygopetalum Mackay, which 
blooms during the mid-winter months; the present plant is both a winter and spring 
bloomer, flowering in great profusion, and oftentimes throwing two scapes from a 
single growth. This, the best form of Z. crinitum, bears the name of c@eruleum; 
another variety, or perhaps the typical form, has the lip with downy lines of rosy 
red or pinkish hairs. Blue, however, being the most unusual colour amongst 
orchidaceous plants, obtains more notice from cultivators, and this colour, in various 
shades, is quite characteristic of the genus, a few examples of which have already 
appeared in these pages, of which Z. Clayi, t. 50; Z. rostratum, t. 78; Z. Gau- 
tierii, t. 28; and Z. Burkei, t. 142, may be taken as examples. The plant here 
figured flowered in our own collection, in the Victoria and Paradise Nurseries, during 
the spring months of the present year, where the plant usually contributes largely 
to the display we are enabled to maintain at that season. : : 
Zygopetalum crinitum ceruleum is a free-growing evergreen plant, easily culti- 
tivated into a handsome specimen, and blooms profusely during the winter and 
spring months, the flowers being large and showy, lasting a very long time 
in full beauty. During the summer season, its period of growth, it requires a
