cannot be even approximately imitated artificially ; the cultural routine 

 here formulated is thence, in a great measure, founded upon experience 

 derived from observation of the behaviour of the plants under the 

 altered conditions of their environment in the glass houses of Europe. 

 The pseudo-bulbs should be re-potted about a fortnight after they have 

 flowered, that is to say, set in shallow pans in a compost of two-thirds 

 fibrous peat, and one-third chopped sphagnum, to which a little leaf-mould 

 and sand should be added.* The pans should be filled to one half of 

 their depth with broken crocks, for drainage, upon which it is usual to 

 place a layer of sphagnum for the two-fold purpose of keeping the com- 

 post dam}) and preventing its sifting through the drainage. The remainder 

 of the pan should be filled to within half an inch of the rim with 

 compost, in which tlie bullis should be placed with their roots half an 

 inch below tlie surface ; the spaces between the bulbs, and between 

 them and the rim should be covered with living sphagnum for retaining 

 moisture. The pans should then be suspended near the roof-glass of 

 any house in which an intermediate temperature is maintained, and 

 water withheld till the plants commence growing, or given only in 

 sufficient quantity to keep tlie surface sphagnum alive. As the roots and 

 foliage develop, the waterings must be more frequent and more copious, 

 and may be supplemented occasionally by a little weak liquid manure. 

 Pleione lagenaria, P. iJroicox and its variety Wallichiana may then have a 

 light position in the Cattleya house. P. Reichenhachiana and P. macidata 

 require a little more heat. P. humitis and P. Hooker lana, coming from a 

 high alpine region, should be placed close to a ventilator, or in a cooler 

 house. "When the foliage begins to turn yellow, the waterings must be 

 diminished in frequency and quantity till only sufficient is given to keep 

 the bulbs plump. \Yliile in flower, the Pleiones may be kept in the 

 Cattleya house or in the cool house, provided the temperature at no time 

 descends below 7° C. (45° F.)

" Pseudo-bull )s ovoid, smooth, ^ — 1 inch long. Leaves 1 — 2 inches 

 long, elliptic-lanceolate, acuminate, finely plaited. Flowers 2 — 2| inches 

 across the petals, rose-purple with a paler lip blotched at the apex with 

 broAvn-purple ; sepals and petals variable in breadth, elliptic-lanceolate, 

 acuminate, spreading ; lip convolute and cylindric as far as the lateral lobes 

 extend, then expanded into a small, retuse, terminal lobe ; disk with 

 several slender crested lamelte. Column slender, expanded at the tip."

* Some cultivators prefer a smaller proportion of peat, and substitute fibrous loam mtli a 

 small quantity of dried cow manure.
