MASDEVALLIA 



MASI)h:VALLIA 



especially at ui^dit, when a li^bt syringing- overhead will 

 also prove beueticial. iMidiiay syringing in liot weather 

 is often injurious and should be done with caution if at 

 all. More benefit will result from hosing down the 

 shelves and paths at intervals of three or four hours, as 

 it will help to reduce the temperature. 



i\Iasdevallias need a great deal of water at the roots at 

 all seasons, and the soil should never be allowed to dry 

 out, as they have no fleshy pseudobulbs to protect them 

 against extreme changes. Light syringing overhead 

 <luring winter and spring in fine weather will assist in 

 checking thrip and red spider, and a weak solution of 

 tobacco may be added with good effect. 



The best season for repotting and basketing the plants 

 is during Novenil)er and Decemtier, and the best gen- 

 eral compost is a mixture of clean peat fiber and sphag- 

 num moss chopped rather fine and well mixed, some 

 sections requirinc: in addition a portion of chopped sod. 

 About one-third of the space should be devoted to clean 

 ilrainage cousistiug of either l>rokeQ charcoal or pot- 

 sherds. 



M. coriacea, elephatificeps , Pen'sfcrlit, HeichenJtaclii- 

 i'}ia, and kindred species, grow be^it in small pots, and 

 should have one-third chopped sod added to their potting 

 compost. M. tna<:rura, Svhlhiiii, T'>r(irin}sU, ainabilis, 

 <-occinea, Veitchiana, friatn/'i Inris , [lottislirtu , mtiscosa, 

 and the numerous other allied .species, grow equally well 

 ill either pots or Itaskets, but should the latter be used 

 it would be well to add a small portion of chopped sod to 

 Ihe compost to make it more firm and less porous; the 

 sod has a cooling effect on the roots. M. bcfht, Cardcri, 

 <.']te.sf<;rtoni, Cln'nia'ra , Iloutfea n'l and their allies nearly 

 ;d! have pendulous flower-scapes, and should be sus- 

 ]»ended from the roof in baskets in a compost of equal 

 parts chopped peat-fiber and live sphagnum, with a little 

 leaf -mold added. The flower-scapes often penetrate 

 through the compost; for this reason little or no drainage 

 should be used, as it may retard their progress. 



To increase the stock the plants must be divided dur- 

 ing the early winter; this will give them a chance to 

 reestablish themselvps before the following summer. 

 The}' must not be broken up into too small pieces, as it 

 has a tendency to weaken them. Cult, by R. M. Grey.
