80 THE ORCHID REVIEW. [ MARCH, 1907- 
The great notoriety attaching to the third region was caused by the dis- 
covery of varieties with large spots. Although I was one of the first, if not 
the first, to explore these mountains, I must state that the first to put me 
on the track was poor Millican, long since dead. He had _ previously 
explored a part of the mountains, round about Puripi, of which he speaks 
elsewhere, if I remember rightly, in his book’ The Adventures of an Orchid 
Hunter. 
My first importations arrived in Europe towards the beginning of 1895,. 
and everyone recalls the great sensation caused by the very beautiful 
varieties shown several months later at the Temiple Show, and afterwards at 
other meetings of the Royal Horticultural Society. 
The large-spotted forms are not found uniformly distributed throughout 
the zone; they have their home only on certain mountain sides. This. 
explains why some importations produce more varieties than others 
although all are collected in the same group of mountains. Under excep- 
tional circumstances one meets with forms of O. crispum beyond comparison 
in the really remarkable beauty of the flowers, rivalling even the marvellous. 
forms of Pacho. 
Among other species which are found here, more or less abundantly, 
with crispum are O. gloriosum, O. Lindleyanum, with the variety mirandum, 
O. Hunnewellianum, and, in a very restricted district, O. triumphans. 
4. VELEZ REGION,—The O. crispum found in this region occur prin- 
cipally in the high mountains which surround the little village of Bolivar- 
They are known by the name ‘ Velez type.” With the exception of a 
small chain of mountains extending from the Valley of Jesus in the direction 
of Sabaya, in which the type is regular, the O. crispum collected round 
about Bolivar are mostly poor. The flower stalks are weak, often shorter 
than in the Chiquinquira type, and the flowers, with certain rare exceptions, 
below the average in merit. In this region O. Hunnewellianum flourishes, 
in company with O. gloriosum.

ODONTOGLOSSUM LEAVES DECAYING AT THE TIPS. 
THE correspondent who, at page 62, asks about the cause of his Odontos 
“tipping ” and losing their leaves, wishes for the opinion of other growers. 
I am very successful with mine, and I think only because I do not let the 
temperature run below 50° in winter, and take care that the house is com- 
paratively dry by night. If moisture remains on the leaves all night, at 
the low temperature of 45°, it is sure to set up rot at this time of the year. 
Of course later on it will not matter, but in winter everything depends upon 
the question of moisture. Zipa A. WaRD.
