Gardening for Amateurs 



must be kept cool and moist during the directly the sun shines on the roof, but in 

 summer months, by ventilation and shading winter the atmospheric moisture must be 



less. Although most Or- 

 chids benefit by a rest 

 after the pseudo-bulbs are 

 fully matured, the Odonto- 

 glossums named above 

 are best kept just moist 

 at the roots at all times. 

 There are a few that 

 may be grown at the 

 coldest end of the inter- 

 mediate house, such as 

 0.' Rossii, a pretty little 

 plant with white, rose- 

 flushed flowers which 

 appear during winter. 

 This should be grown 

 in shallow pans, and 

 suspended about 2 feet 

 from the glass. Another 

 distinct Odontoglosstim 

 is 0. citrosmum, which 

 has pendent stems of 

 rose and white flowers ; 

 it should be planted in a 

 teak-wood basket or pan 

 and suspended. When 

 the bulbs are developed 

 it must be kept fairly dry 

 until the flower spikes 

 are seen emerging from 

 the new growth in spring 

 or early summer. A 

 few other desirable sorts 

 are often referred to as 

 the Mexican section, em- 

 bracing Odontoglossum 

 Insleayi, 0. Cervantesii, 

 and the Guatemalan O. 

 grande. A little osmunda 

 fibre may, for these, be 

 added to the potting 

 mixture with advantage, 

 and a light position in 

 the intermediate house is 

 advisable.

 Oncidiums there are kinds 

 suitable for the warm,
