284 THE ORCHID REVIEW. [SEPYEMBER, 190%, 
ORCHIDS AT GUNNERSBURY HOUSE, ACTON. 
ORCHIDISTS among the delegates to the Hybridisation Conference who ; 
visited the remarkable gardens at Gunnersbury House, Acton, on Friday, 
August 3rd, at the kind invitation of Leopold de Rothschild, Esq., were 
pleased to find that the Orchid collection is an increasing one, several i 
houses being now devoted to them, and they appear to be thriving just like | 
everything else under Mr. Hudson’s care. There is a Cattleya house devoted — 
to species and hybrids of Cattleya, with a fine series of Leelio-cattleyas, but — 
we only noticed a couple of good Cattleya Harrisoniana actually in flower. — 
An adjacent house contained a nice batch of the beautiful Vanda cceruleain 
bloom. We also noted a fine lot of Dendrobium formosum, which has — 
long been cultivated here with great success, and Mr. Hudson pointed out — 
several sturdy little seedlings growing on an imported plant, having come 
home with it. A batch of Cattleya Triane, Dowiana and Warscewicai : 
were doing well here. : 
A house is now devoted to Odontoglossums, the plants being arranged 
well up to the light, with ample shading, and appear very promising. Not 
much was in flower,’ but. it may.be remembered that one interesting 
novelty has appeared here, namely, O. X Hudsoni, described at page 143, 
as a natural hybrid between O. gloriosum and O. Hunnewellianum. In 
another house we saw a fine spike of the handsome Phalznopsis amabilis, 
and plants of the brilliant Habenaria militaris, with a fine panicle of 
Oncidium varicosum Rogersii, and further along we noticed plants of : 
Epidendrum vitellinum, Cattleya Leopoldi and C. Gaskelliana in bloom. — 
It was a hurried visit, as there was so much to see in other departments — 
and perhaps we shall be able to see more of the collection on some future 
occasion,

HYBRIDISING WITH MIXED POLLEN. 
A FLOWER of a very pretty Leelio-cattleya is sent from the collection of 
R. G. Thwaites, Esq., of Streatham, by Mr. J. M. Black, who writes that . 
it is a seedling from Lelia xanthina, but that the pollen parent is uncertain, . 
because one pollen mass from Cattleya gigas and one from C. Dowiana — 
aurea were used simultaneously, and the question is what has happened ! 
The two pollen parents are not structurally very different, and as the seed | 
parent is yellow, it may be a little difficult to decide the parentage. Could 
anything equivalent to a cross with C. x Hardyana be obtained by Sa 
means? Lastly, is it not possible that two distinct crosses may Ps 
obtained from the same pod ? : 
The flower sent is larger than Lelia xanthina, and light yellow . 
colour, with a light purple front lobe to the lip, the veins being somewhat
