conspicuous. Numerous Cypripediums were in flower, including C. Exul 
in variety, one flower having the lower sepal variegated with white and 
yellow, the rare C. Druryi, and C. X Littleanum, the fine natural hybrid 
from C. Lawrenceanum and C. Dayanum, figured at page 209 of our third 
volume, and it may be remarked that the characteristic hairs of the latter 
were specially well'developed on this occasion, so long in fact as to remove 
the last doubt of this species being the other parent. Dendrobium 
primulinum giganteum was specially fine, one flower measuring 1% inches 
across the lip, a circumstance altogether exceptional. Several good D. 
thyrsiflorum, a well bloomed Ansellia gigantea, Leptotes bicolor with half-a- 
dozen good flowers, and a dozen plants of Cymbidium Lowianum must also 
be mentioned, as reflecting great credit on Mr. Howard’s management of the 
collection. 
HYBRID ODONTOGLOSSUMS. 
(Continued from vol. iii, p. 329). 
ODONTOGLOssUM X ADRIAN&.—An additional hybrid must now be added 
to those from the Bogota district. Odontoglossum Hunnewellianum was 
originally described as coming from the Bogota district, and now evidence 
comes to hand that it grows intermixed with O. crispum. Some time ago 
I saw plants of it which were said to have appeared in an importation of 
O. crispum, and more recently several examples have flowered which are 
so precisely intermediate between the two species as to leave no doubt 
that they are natural hybrids derived from this parentage. The first which 
I know of flowered in the establishment of Messrs. L. Linden & Co., at 
Moortebeek, last season, and was described and figured under the name of O. 
x Adriane (L. Lind. in Sem. Hort., i, p. 150; Lindenia, xiii, p. 31, t. 590). 
Then plants flowered in the collection of W. Thompson, Esq., Walton 
Grange, Stone, and R. G. Fletcher, Esq., of Withdeane, Brighton. I also 
saw examples at Moortebeek last month, and at the Temple Show in the 
collections of Messrs. Linden (three or four plants), Sander, and M. A. 
Madoux. These I have seen, besides which I have heard of two or three 
other plants, most of them having flowered among O. crispum, possibly, I 
would suggest, from a different locality, otherwise the hybrid would 
probably have been noticed before. 
The different plants vary somewhat in size, shape, and markings, as 
hybrids generally do, but all combine the characters of the two parents. 
The sepals and petals are broad, and light yellow in colour, often whitish 
towards the centre, and bear numerous red-brown spots, those on the sepals 
being more or less confluent into larger blotches. The lip is also broad and
