268 THE ORCHID REVIEW. [SEPTEMBER, IQIO. 
purple, while the base of the lip is very dark purple, and the apex white.. 
Many plants of this cross and of seedling O. crispum were in bloom. We 
may also mention a very white form of O. xX percultum, most like O.. 
Pescatorei, and an immense form of O. X Rolfez which is being used as a 
parent, two capsules being partly formed. 
Seedlings of numerous interesting crosses were pointed out. A batch 
of seedlings from Miltonia Warscewiczii var. Weltoni, crossed with a goodi 
spotted Odontoglossum crispum, had very flat bulbs, and were growing 
vigorously. They will be forms of Odontonia Lairessez. Seedlings of 
Odontioda Bohnhoffie x Odontoglossum xX Ossulstoni were growing well. 
Nice plants of Odontoglossum X Ceres (Rossii X Rolfez), and a couple 
of seedlings from O. maculatum and O. X Wiganianum were pointed out,. 
with others from O. Uroskinneri X Harryanum, O. X armainvillierense X 
Rolfez, and a lot of seedlings of O. crispum. A batch of Oncidium X 
hybridum (trigrinum X lamelligerum), the first artificially raised Oncidium 
see p. 8), was also noted, and the list might be greatly prolonged. 
A house is set apart for select varieties, and here we saw the beautiful 
Odontoglossum crispum xanthotes Snow Queen throwing up a very strong 
spike, O. c. virginale Jules Hye with a smaller spike, an imported O. 
crispum with an orange-coloured disc to the lip and very few spots, O. 
Pescatorei Charlesworthii, a very good parent, with a fine spike, the richly- 
coloured O. Uroskinneri incarnatum, a good O. X armainvillierense with six 
side branches and an aggregate of twenty-nine white flowers, with clusters. 
of purple spots on the segments, some good spotted seedling forms of O. 
crispum, &c. The plants here were mostly being grown on. 
The Cattleya houses are filled with thousands of seedlings in every: 
stage, and were equally interesting. The seeds are sown on canvas strained 
over balls of sphagnum moss and inserted into pots, while a little finely- 
chopped compost is inserted into the cavity at the sides, to prevent the seeds. 
from slipping down and getting lost. Many interesting crosses were pointed 
out, but we cannot enumerate them, and the flowering plants were mostly 
in the main range, which we shall come to presently. 
Some interesting experiments are being carried on, one of them being an 
attempt to obtain a race of large yellow hybrids, a type much wanted. One: 
of these experiments is Lzliocattleya Cappei crossed with Cattleya x Lord 
Rothschild, and the result again crossed with C. Dowiana aurea. The: 
problem is being attacked other ways, and the result will probably be: 
reached in time, though the difficulty is that so many of the C. Dowiana 
aurea hybrids revert to purple. 
We also noted a lot of choice Cypripedium hybrids in every stage, some: 
of them showing for flower. Although so many have been raised there is. 
plenty of room for improvement, and a severe selection of parents is.
