OCTOBER, 1922.] THE ORCHID REVIEW. 305 
house, is situated so that one side receives the sun in the morning and the 
other in the afternoon. It is twelve feet wide and about fifty feet in length, 
and has three rows of hot-water piping on each side. The desired tempera- 
ture is thus easily maintained by not over-heating the pipes, and, as a 
further precaution, porous tiles, which are kept damp, are above them in 
order to prevent any direct current of dry air from reaching the plants. No 
Odontoglossum house is considered complete without fine varieties of the 
ever-popular O. crispum. Here are two of the very finest: one named 
Renown, with pure-white. flowers, the other, called The Chairman, with 
blush tinted segments, but both of excellent form. 
A number of the best hybrids are represented by paintings, and by this 
means their various meritorious points can be seen at any period of the 
year. QO. Aireworth magnificum is very effective, the round segments being 
rose tinted and blotched with purple. In O. Carola var. Sunrise (Queen: 
_ Alexandra x Scottianum), the flowers are golden. yellow with reddish 
spotting. In O, Eximillus the reddish blotching is on a whitish ground, 
and in a very fine variety of O. eximium called Daphne the blotching is 
bright purple on a blush tinted ground. Very much of the attractive nature 
of an Odontoglossum is due to the arrangement of the spotting. There is: 
in this house a strong plant of O. Empire, the flowers of which are clear 
white, but with just a few little spots of bright violet colour. The effect is 
in this case simply charming. The brightness of the violet on the clear 
ground being most pleasing. If we look for the origin of these spots and 
their peculiarly rare colour it can be traced back to the influence of O- 
Pescatorei, which is contained in the parentage. 
Among the purple coloured flowers fine results are to be seen in Ov 
President Poincaré, of rich plum-purple, and in O. Purple Queen, while in 
O. Nysa there exists a flower of reddish colour obtained through the use of 
the little Hunnewellianum species. An elegant hybrid producing flowers 
of brownish-purple colour can be seen in O. Fabia. Odontoglossum species 
are not grown so plentifully as in former days, but there is always a certain 
amount of interest attached to them. In this house is a plant of the rare 
O. Harryanum nigrum, which although small, will no doubt improve 
rapidly under the present suitable surroundings and treatment. 
Odontoglossum Faustina, Claygate Lodge variety, was exhibited at the 
Chelsea Show of the current year, and was unanimously awarded a First- 
class Certificate. The spike then carried six finely developed flowers, all 
the segments being of excellent formation, rose tinted, and blotched with 
teddish-purple. Another excellent hybrid is to be seen in Oeenhogs 
Colinge, the segments of which are solid vermilion red, except for a narrow 
white margin which accentuates the intense coloration. There is a wide 
Tange of Odontiodas, including the very fine Oda. magna rubra, some fine
