Shuttryana and var. Chamberlainii, Gairiana, Stella, Chelsonii, Geleniana, 
Rushtonii, and several others. 
Such species as M. platyglossa, M. leontoglossa, and several others that 
produce their flowers in a downward direction should be placed in shallow 
baskets. There are many other Masdevallias that could be mentioned, but 
it is not necessary to give a complete list. 
The best months for potting or topdressing these plants, if the roots. 
have to be disturbed, are the beginning of September and February. The 
present time is preferable for the majority of them, because it is now that 
they make the greatest number of roots, and the cool moist weather during 
the autumn is favourable to their speedy re-establishment. In most 
collections where these plants are cultivated there are sure to be some 
specimens that need attention. Large over-grown masses, that have 
become bare of foliage in the centre, may be divided and made up anew, or 
may be carefully separated and put into small pots and grown on into nice 
compact specimens. In some cases where the soil has become sour and 
stagnant it may be carefully removed and replaced with fresh. Masdevallias, 
especially the strong-growing kinds, make many roots, and accordingly 
require a good amount of space. . 
' The pots should be two-thirds filled with clean crocks for drainage, while 
the potting material may consist of chopped osmunda fibre. Pot moderately 
firmly, keep the base of the leaves on a level with the rim of the pot, and 
carefully work the compost between the roots. Do not afford much water 
until the roots are seen pushing their way into the new fibre, or both they 
and the leaves will quickly decay. Shade the plants for a time from all 
sunshine, and maintain a moist atmosphere by damping between the pots 
two or three times a day, or, if the weather becomes colder, one damping 
will be sufficient. M. tovarensis should not be disturbed by repotting now, 
unless a plant be in bad condition at the root. Masdevallias delight in 
plenty of fresh air, but all cold draughts should be avoided, especially when: 
the wind is in the north, east, or north-east. Ventilate freely whenever the 
external air is calm and moist, and the temperature outside is above 50°. 
Coo. HousE.—Other plants that thrive well under the same cultural 
conditions as the Masdevallias are Pleurothallis, several of which are well 
worth growing on account of the singular beauty and curious structure of 
their flowers, as P. Roezlii, picta, ornata, punctulata, macroblepharis (the 
Gnat Orchid), rhombipetala, &c., also many kinds of Restrepia, Octomeria, 
Stelis, Aérides japonica, Angraecum falcatum (with fragrant white flowers), 
Promenza xanthina, stapelioides, and Rollissonii, Stenoglottis fimbriata, 
the pretty Australian Sarcochilus Fitzgeraldii, Hartmannii, &e., &c.
