Rustic Adornments . 
P. scaberula , P. serrulata , P. s. cristata : all possess the desirable qualities of 
an elegant and graceful habit, and grow freely with ordinary management. 
The two best Selaginellas for carpeting the case are S. Kraussiana (erroneously 
called denticidata) and S. involvens . S. apoda grows freely in a case, but is 
liable to mildew and decay in a confined atmosphere during the winter. Of 
the tall or erect growing selaginellas S. grandis , S. umbrosa, and S. Victories 
are to be specially commended as suitable for cases. 
A SELECTION OF ORCHIDS FOR CASES THAT ARE NOT HEATED. 
The most suitable orchids for unheated cases are Barkeria Skinneri ', 
Cattleya citrina (this should be secured to a block of wood—cork is the most 
suitable—and suspended with the foliage downwards), C. Skinneri , Cypripe - 
dium insigne , C. venustum , Epidendrum vitellinum , Lcelia albida , Lycaste 
Skinneri , Odontoglossum , O. Alexandres grande , O, pule helium, O. Rossi majus , 
Oncidium bifolium , O. ornithorhynchum, Pleione humile , P. lagenaria , Sophro- 
nitis grandiflora, Stanhopea ocidata , tigrma , and Z<ygo pet alum Mackayi. 
The plants should be potted in a mixture of sphagnum and peat, the pot s 
being half filled with crocks. Place the case in a window facing as much 
towards the south as possible, and throw some thin material over the case 
when the sun is shining brightly, to prevent its burning the foliage. The 
shading must be thin to admit the warmth from the sun, especially during 
the early part of the summer, when the plants are making fresh growth. 
After the middle of August, expose freely to the light, to ensure the young 
growth being well matured, otherwise the plants will not flower freely. A rather 
liberal supply of water will be necessary during the summer, when the plants 
are growing vigorously ; but when at rest through the winter, only sufficient 
must be supplied to prevent the leaves flagging. The case must be sufficiently 
ventilated to maintain a pure atmosphere; but the air must be admitted 
carefully, and mild weather should be selected for air-giving.
