18 THE ORCHID REVIEW. [JANUARY 1912 
great favourite with Orchid collectors. It grows at an altitude not lower 
than 2000 metres (6500 ft.), and the temperate house suits it best. Its 
branching stems produce great numbers of richly dark blue and white 
blossoms borne in trusses, and lasting in bloom for several weeks. The 
flowers are over an inch indiameter; the sepals and petals at the base are 
white, with a great blue blotch at the edges; the lip ovate-oblong and of the 
‘same colour.’ Some plants were sold by Messrs. Protheroe and Morris 
at about the same time, and soon flowered, for on August toth one of them 
received an Award of Merit from the R.H.S., when exhibited by. 1. 
Statter, Esq., Stand Hall, Manchester. For some time a difficulty was 
experienced in cultivating it, probably because the necessity for cool treat- 
ment was not fully realised, but after some experiments it was found that 
the roof of the Odontoglossum house was the most suitable place for 
it, and in such a position the plant figured has long been grown. In 
such a position, too, was grown the remarkable specimen for which 
Richard Ashworth, Esgq., Newchurch, received a Cultural Commendation 
at the Temple Show in 1909 (O.R., xvii. pp. 182, 205), and at Harefield 
Hall, Wilmslow, we have also seen a number of plants growing and 
flowering freely suspended from the roof of the Odontoglossum house. It 
is now known to be a native of the province of Benguet, in Northern 
Luzon, having since been collected by Elmer, on Mt. Santo Tomas. It 
also occurs on Mt. Halcon, in the Island of Mindoro, where it was collected 
by Merrill, in dense wet mossy forests at 8000 feet elevation, and by 
Merritt at 6500 feet. The latter mountain is described as having a 
remarkably humid climate, the rainy season continuing for practically nine 
months of the year, from May to January without interruption, while the 
remaining three months are by no means free from precipitation. From 
these facts one can readily understand why this beautiful species requires a 
cool mcist climate for its successful culture. For the loan of the block we 
are indebted to the courtesy of the Editor of the Journal of Horticulture. 
CALENDAR OF OPERATIONS FOR JANUARY. 
By J. T. Barker, The West Hill, Hessle, E. Yorks. 
THE cultivator will now be looking forward to longer days, when his plants 
will once more be starting into growth, and at no season of the year are they 
more interesting to the persons responsible for their well-being. The 
general winter treatment must be continued for the present month, and the 
principal work to occupy our attention will be to maintain the temperatures 
(especially should cold weather prevail)—to provide suitable atmospheric 
conditions in the houses, avoiding extremes of all kinds, and making no 
attempt to force growth; also to get our plants into a state of cleanliness, 
ready for when the busy season of potting arrives.
