2 5 o THE ORCHID REVIEW. 



long, with the remains of the shrivelled perianth segments. All these 

 characters are well shown in our illustration, ami it will also he noticed 

 how short is the pedicel below the capsule. All these characters agree 

 with Brassavola, not with Laelia, and it is certain that the plant does not 

 belong to the latter genus. Should Mr. Thwaites succeed in raising 

 seedlings it will be interesting to see what they are like, because one of the 

 parents is an albino. 



Dendrobium X Huxteri.— Mr. Thwaites also alludes to the remark- 

 able Dendrobium X Hunteri, described at page 153, remarking :— " It 

 would be interesting if Mr. Hunter would communicate to you the result of 

 further flowerings, as I think it not at all unlikely that some of the other 

 seedlings may more nearly resemble D. Brymerianum, and I hope that/some 

 may be intermediate." It maybe added that we know of one attempt to- 

 repeat this cross, the pollinia of D. Brymerianum and D. nobile having 

 been reversed, but in neither case did the capsules swell. 



CALENDAR OF OPERATIONS FOR AUGUST. 



By John Mackay, The Gardens, Highbury, Birmingham. 

 The weather continues to be very changeable for the time of year. 

 During the past month we have experienced some cold and comparatively 

 sunless weather; in spite of this, however, some Orchids continue to thrive,, 

 especially Cool Orchids, such as Odontoglossums and Masdevallias, which 

 have greatly benefited by the cooler conditions which have prevailed. On 

 the other hand Dendrobiums, Cattleyas, and Ladias will be much later than 

 usual in completing growth ; some of these, indeed, are only commencing 

 to push forth new growth, and these, it is unnecessary to say, should be 

 given every encouragement to make up for lost time. 



A few Dendrobiums of the early flowering section that have completed 

 growth, will now require to be removed from their present conditions to 

 one more favourable for ripening their pseudobulbs. This alteration in 

 conditions should be done in such a way that no harm from sudden check 

 will result to the plants. Where a resting house is not set aside for this- 

 purpose, a vinery will be found a suitable place to meet their requirements. 

 The plants most forward here, and which will soon have attention at the 

 present season, are D. Wardianum, D. aureum, D. nobile, D. X Ainsworthii, 

 D. x euosmum, D. x Cassiope, D. x endocharis, and D. X Curtisii. 

 These are amongst the earliest, but the season will be found late generally, 

 so that care must be taken not to remove them until they are quite ready, or 

 shrivelling of the pseudobulbs will take place. Give only sufficient water 

 while resting to maintain the pseudobulbs in plump condition.
