•cultivation, and beginners should leave them alone until they have had a little experience 

 with more easily-grown ? kinds. They greatly dislike being disturbed, and cannot well 

 be too heavily shaded in summer. The roots are large and somewhat fleshy, so rough 

 crocks and charcoal must be freely used with the material mentioned above. Four 

 species are recommended, namely : W. discolor, — Scapes one-flowered, the flower 

 2| inches across; sepals white; petals tinged with purple; lip white in front and on 

 the disc, the rest purple. 

 Costa Eica, 1853 (*'). W. 

 marginata. — Single-flowered 

 spikes ; flowers 3 inches 

 across, creamy white ; lip 

 purple. New Grenada, 1853 

 (1). W. Lindeni— Allied 

 to the last-named, colour 

 pure white with raised 

 purple lines (Fig. 91). And 

 W. Wendlandi. — Very 

 large and handsome flowers, 

 4 inches across, white, with 

 the exception of the lip, 

 which has a purple centre.

and most of the species are 



easily grown in pots of peat fibre and sphagnum moss. They must be well watered, 

 especially the strong-growers, such Z. Mackayi, and no actual dry rest is needed by 

 any. Z. rostratum and Z. maxillare are the most difficult to contend with. They are 

 most likely to be satisfactory on blocks of Tree-Fern stem, wired down firmly with a 

 thin layer of moss about the base of the pseudo-bulbs. Especial care is necessary 

 to keep down insects.
