Zygopetalum—continued. 
leafless, many-sheathed, one-flowered or terminated by 
a loose raceme; bracts small or rather broad. Leaves 
distichous, membranous or rather rigid, slightly plaited 
or with elevated veins. Stem leafy, short, at length 
thickening into a pseudo-bulb. The flowers are generally 
produced during winter—a circumstance which greatly 
enhances the value of Zygopetalums as decorative objects. 
The robust species, such as Z. Mackayi, may be grown 
along with Cattleya Mossie. They should be potted in 
rough peat and sphagnum, and watered freely when 
making their growth. During winter, they require only 
sufficient moisture to keep them from shrivelling. The 
Pescatorea section are much more difficult to manage. The 
large-leaved kinds may be grown in pans or baskets, 
using a mixture of peat-fibre, sphagnum, and lumps of 
charcoal. Some growers place these kinds on flat, dish- 
like saucers, with several large holes in the bottom, and 
simply place nodules of peat and charcoal about the 
roots as they multiply. Others fasten them on to large 
blocks of birch, placing the plants on the bark side of 
the block. The small, delicate kinds, such as Z. grami- 
neum, thrive best in teak baskets. All the species like 
plenty of moisture when in full growth, and none should 
ever be allowed to get quite dry.
