In winter the teniperatinv should range between 50° 

 juul 5,")° K. at night and abo\it tiO" dining the day or 5" 

 more on mild days, with weak solar heal and ventila- 

 tion. Artificial lieat must be dispensed with as early in 

 spring ;ti possible, and during summer the temperature 

 kept :»i! low as the weather will permit, ventilating 

 friH'ly, especially at 

 night, when a light 

 syringing overhead 

 will also prove 

 beneticial. Midday 

 syringing in hot 

 weather is often in- 



i'urious and should 

 ic done with 

 tion if at :dl. 

 benefit will resul 

 from hosing down 

 the shelves and 

 paths at intervals of 

 three or four hours, 

 as it will help to 

 reduce the tempera- 

 ture. 



Masdevallias 

 need a great deal of 

 water at the roots 

 at all sea,sons, and 

 the soil .should never 

 be allowed to drj- 

 out, as they have 

 no fleshy pseudo- 

 bulbs to protect 

 them against ex- 

 treme changes. 

 Light syringing 

 overhead during 

 winter and spring 

 in fine weather will 

 a.ssist in checking 

 thrip and red- 

 spider, and a weak 

 solution of tobacco 

 may be added with 

 good effect. 



The b&st season 

 for repotting and 

 basketing the plant,s 

 is during Xovember 

 and December, and the best general compost is a mix- 

 ture of clean peat fiber and si)hagnuni moss chopped 

 rather fine and well mixed, some .sections requiring in 

 atldition a portion of chopped sod. About one-thinl of 

 the space shoulil b(^ devoted to clean drainage consisting 

 of either broken charcoal or potsherds. 



M. coriacea, M. elephanticeps, M. Perisleria, M. 

 Reichenhachiarui, and kindred species, grow best in 

 small ]X)ts, and should have one-third chopped sod 

 a'ided to their potting compost. M. macrura, M. 

 iSchlimii, M. Uirarenxis, M. amabilis, M. cocciiiea, M. 

 Veilchiana, M. IrianguUirin, M. pobj.ilicla, M. muncosa, 

 and the numerous other allied species, grow equally well 

 in either ]x>t» or baskets, but should the latter be used 

 it would ix: well t<i :uld a small portion of choi)i)ed sod to 

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

 and has a cooling effect on the roots. M. h/dta, M. 

 Carilirri, M. C'tu;nUrU>nii, M. Chimera, M. IltnMfiana 

 and their allies nearly all have pendulous fiower-scapes, 

 and should b<; susfxmded from the roof in baskets in a 

 ctjmjxmt of equal parts chopped peat^fiV)er and live

sphagnum, with a little leaf-mold added. The flower- 

 scapes often |)riielrate llirougli the coiiiposl ; tor this 

 reason lit lie or no drainage should be used, as it may 

 retard their progress. 



To increase Uie slock 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.
