THE FLORAL WORLD AND GARDEN GUIDE. 943 
Odontoglossum Roezli, in my opinion, is one of the most useful of 
the Odontoglots introduced of late years. It has elegant glossy 
leafage, and broadly expanded flowers, white, with a purple blotch at 
the base of the sepals, and a yellow blotch near the disc of the 
labellum. It is very free-flowering, and with a sufficient number of 
plants may be had in bloom throughout the year, as exemplified in 
our collection. There is a beautiful variety with pure white 
flowers. 
Odontoglossum vexillarium is more attractive in colouring than 
the species immediately preceding it, but both are so distinct from 
each other that they may be considered indispensable to the most 
select collection. The flowers are large, the labellum fully three 
inches across, and the colour is a pleasing shade of rose pink. The 
plant is very free flowering, and examples consisting of two or three 
pseudo bulbs have been exhibited in London bearing from thirty to 
forty flowers. It has flowered most profusely in our collection, 
which includes a large number of plants of this superb species. The 
two Odontoglots here mentioned require a higher temperature for 
their successful culture than Odontoglossum Alexandre, and similar 
kinds. We grow them in the Cattleya house, in which a temperature 
ranging from sixty-five to seventy-five degrees is maintained during 
the summer, and from fifty to sixty-five degrees during the winter 
season, and a most satisfactory growth is the result. 
DRAWING-ROOM FERNERIES. 
BY W. H. HALLIDAY. 
(Communicated to the Massachusetts Horticultural Society.) 
ws LANT cases, as we know them, are classed under two 
m heads. First, the Wardian case, in which are grown 
foliage plants, ferns, etc. ; plants too large or too coarse 
to look well in a small case. Although the first Ward’s 
——- case was only a bottle, in which by accident Mr. Ward 
discovered that plant life could be sustained, from some cause or other, 
we seem to have adopted the name Fernery for cases that are covered 
with a glass shade, in which only the more delicate or smaller varie- 
ties of ferns are cultivated. In this article I will endeavour to give 
some experience I have had with cases varying in size from four to 
fifteen inches in diameter. 
The case may be made of tin, earthenware, or wood; it matters 
not which, so long as proper regard is had to drainage. This, as in 
Wardian cases, is of vital importance to the healthful growth of 
plants under the fern shade. I say this is of the first importance, as 
many persons who have the management of ferneries, use so little 
judgment in their care, that without a proper outlet for water, the 
soil soon becomes perfectly saturated. I have seen more plants 
destroyed in cases from the want of drainage and from over-watering 
than from any other cause. Most of the failures I have met with 
August.
