AUGUST, 1907.] THE ORCHID REVIEW. 227 
bination. Returning to Odontoglossums,:we noted a batch of O. Edwardii; 
O. Hunnewellianum, O. Uroskinneri and O. Rossii all crossed with O. 
Pescatorei, plants of the latter being three or four years old ; O. sceptrum 
and O. Pescatorei crossed with O. crispum; O. Harryanum and O. x 
ardentissimum crossed with O. crispum Poultoni; and seedlings obtained 
by intercrossing blotched forms of O. crispum. 
Passing into another house we noted a beautiful batch of Odonto- 
glossum X Rolfez, and counted eleven spikes pushing up. Mrs. Thwaites 
remarked that the cross was made both ways, both Pescatorei and Harry- 
-anum being used as seed bearers, and both were showing for flower. Near 
by were good plants of O. Harryanum xX ardentissimum and Cochlioda 
Neetzliana X O. crispum. O. Rossii was bearing capsules as the result of - 
crossing with O. Edwardii, and a good many other capsules were in 
evidence. A good many examples of O. crispum were in flower, 
with a few O. luteopurpureum, and the large and handsome O. Pescatorei 
Grand Duchess, the latter having just been crossed with Cochlioda 
Noetzliana as an experiment. A very interesting remark came out in this 
‘connection. The only three Odontoglossums which have been successfully 
crossed with this Cochlioda are O. cirrhosum, O. ramosissimum and O. 
Edwardii. In all the other crosses (including some not enumerated) it was 
the seed bearer. Other trials may be made, for a few examples were now 
in flower. An interesting experiment of another kind was pointed out here, 
A plant of Charlesworth’s form of O. crispum xanthotes, with two old 
bulbs and a growth, was,purchased about a year ago. Some time later the 
thizome was cut through to separate the two bulbs, and both have 
produced a good break, so that there are now three & Biapls which will be 
potted separately in due time. 
The Odontoglossums have occupied so much space that other things 
must be dismissed very briefly, but they were treated in more detail four 
years ago. And they have made much progress since. There are nine 
houses, largely devoted to hybrid seedlings—in fact it is estimated that over 
95 per cent. are seedlings, mostly raised here. The points to which special 
attention are given include the raising of albino Cattleyas, hybrids of 
Cattleya Dowiana (aurea), of Brassavola Digbyana, and of Sophronitis 
grandiflora, and there is a beautiful series of each. A few seedlings of S. 
grandiflora crossed with C. x Hardyana were pointed out. 
and C. Mendelii have been successfully crossed both ways. 
In another house seeds of a cross between Sophrocattleya x Doris and 
Lelia pumila were germinating, and we noted good plants obtained from 
both C. superba and C. Schilleriana crossed with C. xX Hardyana. A 
batch of thirty or forty seedlings was pointed out in which we have a 
Special interest, for the seed was sent to us by a correspondent, R. M. 
S. grandiflora
