especially at uight, when a light syringing overhead will 

 also prove beneflcial. Midday syringing iu hot 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. 



Masdevallias need a great deal of water at the roots at 

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

 out, as they liave no fleshy pseudobulbs to protect them 

 against extreme changes. Light syringing overhead 

 during 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 November and December, 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 requiring in addition a portion of chopped sod. 

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

 drainage consisting of either broken charcoal or pot- 



M. coriacea, elephanticeps. Peri, 

 ana, and kindred species, grow b€ 

 should have one-third chopped sod 

 compost. M. macrtira, Srlihiiui, j

 and the numerous other allied spec 

 in either pots or baskets, but should the latter be used 

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

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

 sod has a cooling effect on the roots. 31. belht, Carderi, 

 Chfstertoni, Chimtvra, Hoiilteana and their allies nearly 

 all have pendulous flower-scapes, and should be sus- 

 pended 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; forthisreason 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 themselves before the following summer. 

 They must not be broken up into too small pieces, as it 

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



Review of the Sections. 



Section I. Scape 1-fld.: calyx-tube rather nar- 

 row, tubular or somewhat funnel-shaped : label- 

 lum plane Species 1-7 



Section II. Scape 1-fld.: calyx-tube broad, gib- 

 bous or basin-like: labellum plane Species 8-24 



Section III. Scape several-fld.: labellum plane 

 and narrow Species 25-37 



Section IV. Scape mostly 1-fld., pendent or sub- 

 erect: labellum saccate, or at least much broad- 

 ened : tails very long Species 38-44 



Section V. Scapes 1-fld. This section differs 

 from all the others by the subterete Ivs., and in 

 having the tails inserted below the apex of each 

 lateral sepal Species 45
