 cattleva department is favovtible. The oomiK">st shonhi 

 be kept in a moist coui.liti*.)n at all times. The plants 

 are propagated by cutting through tlie rhizeme between 

 the old pseudobulbs at a g >od eye, p)otting up the parts 

 and removing tliem to a rather higher t<,'inperatnre un-

The' Bateiuaunia, Pescatoria and "Warczewiczelhi 

 groups are very similar iu haldt Lif grewth, and all 

 thrive well in orchid basinets suspended from the i-oof 

 of the odontnglossutn or cocdhouse, in a compost con- 

 sisting almost entirely of choiii'eil live sphagiuim, 

 freely interspersed with roiti:rh ]neces cd' (diarcoal. Ati- 

 tnmii is the best time te reba-ket the iilants, as they 

 suffer during the warni weather if disrurbetl .it the 

 roots during spriiti,'. Tiny need a shaded ha-alien, a 

 moist atmosphere and a liiieral supply of water at the 

 roots at all seasotis, Xever allow tliem tn remain <lry, 

 as they have no resting season. 



The' Bollea group is ch.sely alliecl and require-, the 

 same general culture hut needs 0° F, higher temiiera- 

 tiire dnriuir the winter season. 



The Promenfpa irronj-i comprises a few snn^ll-!_n-o\viMg 

 species, all irood suli.iects for the cool deptirtnieut. 

 They grow best suspended from the roof in snitill bas- 

 kets or perforated i»ans in a mixture of peat ti)>er and 

 chopped sphagruim with a litieral sttpply <if wtiter and
