THE ORCHID REVIEW. 297 
S. X Wiganie. In the next house we found many examples of Cattleya 
Harrisoniana in flower and bud, and others of C. velutina and Epidendrum 
prismatocarpum. 
We now came to the house containing two fine plants of Arachnanthe 
Lowii, and found one bearing two and the other four long spikes of flowers, 
the two or three basal ones on each spike being deep orange-coloured, as 
usual. Why these flowers should be so different in colour from the 
remainder still, we believe, remains a mystery. 
In an adjoining house was a batch of plants of the curious Bulbophyllum 
Ericssoni, many flowering examples of Cattleya Leopoldi, one with a spike 
of thirteen fine flowers, a nice lot of C. Loddigesii and Harrisoniana, and 
a pretty hybrid derived from Cattleya intermedia and Lelia harpophylla, 
most resembling the former, but the sepals and petals. tinged with light 
yellow, and the front lobe of the lip mottled with light purple. A house 
containing some healthy plants of Phalznopsis comes last on our notes, 
and here in flower were examples of Angraecum Scottianum and Vanda 
coerulea, together with the handsome Oncidium Lauceanum. 
Of course our notes are not complete. To have included everything, 
even at this season, would have taken up too much space, but we managed 
to note down the principal objects of interest, and from them a magnificent 
group might have been selected. 
ODONTOGLOSSUM CRISPUM AT PACHO. 
(THE NATURAL CONDITIONS UNDER WHICH IT GROWS). 
Your correspondent, Mr. De B. Crawshay, in the September number of 
the Orchid Review (page 213), has asked me to give a detailed description of 
the climate, temperature, and other conditions of the Pacho region. The 
following general remarks may be interesting. 
On the slopes of the Cordillera the altitudinal distribution of Odonto- 
glossum crispum ranges from about 6,000 to 9,000 feet above sea-level. 
The temperature at 6,000 feet ranges from 46° to 75° Fahr. At this elevation 
during the rainy seasons, which embrace more than six months of the year, 
the temperature averages from 50° to 60° daily. In the dry seasons the 
minimum is about 44°, and the maximum 75°. The temperature at 9,000 
feet averages from 6° to 10° less than at 6,000 feet. And at this elevation 
in the dry season the temperature frequently falls to freezing point. The 
greatest altitude at which I have found O. crispum was 10,200 feet. The 
plants were on a rock on the side of a lofty spur of the Andes. At this 
great height ice is frequently found. There plants were growing on a
