38 THE ORCHID REVIEW. [OCTOBER, 1903. 
‘fertilised with Cattleya, and here again the relatively much greater distance 
‘which the pollen tubes have to traverse affords an explanation. When 
such a sharp dividing line is seen the upper part of the capsule may be 
discarded bodily, and only the remainder sown. The charming little 
thybrids known under the names of Sophrocattleya and Sophrolzlia show 
how deserving the group is of more attention. Very much yet remains to 
‘be done, and the results already obtained should stimulate further efforts. 
Epidendrum radicans has yielded a few interesting hybrids, particularly 
‘in combination with other genera, and it is curious to note that in all such 
cases it has been used as the pollen parent. Innumerable attempts have 
been made to utilise it as the seed parent, but, except in the case of pollen 
taken from another species of Epidendrum, always without success. 
‘Capsules are not produced, and there seems to be some complete obstacle 
‘to successful fertilisation, which cannot be overcome. ‘This is the more 
‘curious, because as a pollen parent it has several times been used with 
complete success, the seed parents being Cattleya Bowringiana, Lelia 
‘purpurata, L. cinnabarina, Sophronitis grandiflora, Epidendrum evectum, 
E, vitellinum, and E. xanthinum. The one exception that we remember 
is that seedlings were obtained by Messrs. Sander from E. radicans by 
‘pollen of E. Wallisii (O. R., v., p. 301). There is room for further experi- 
ments here.

NOTES ON PHOTOGRAPHS RECEIVED, 
A SERIES Of very interesting photographs have been received since our 
ast issue appeared, respecting which a few notes should be written. 
First may be mentioned two handsome photographs of Cattleya xX 
Hardyana which have bloomed this year in the collection of Clement Moore, 
Esq., of Hackensack, New Jersey. 
One represents a noble specimen bearing four racemes, and an aggregate 
-of sixteen or seventeen flowers, the best having five. It is fairly typical. 
The other shows .a_ three-flowered inflorescence of a magnificent form. 
Mr. Moore remarks :—“ The large plant is very rich in colour, but the 
“smaller is the finest flower I have ever seen. The colour is intense; the 
sepals and petals are darker than the lips of most Cattleya gigas, and the 
eyes instead of being yellow are dark maroon brown.” The shape is 
excellent, and what we particularly notice is that the characteristic Dowiana 
veining extends all over the yellow in the throat, which is not the case in 
the other form. Another photograph shows a group of C. Warscewiczii 
flowering during the present summer in Mr. Moore's collection, and a 
remarkable lot they are, the photograph showing a complete bank of flowers,
