DECEMBER, 1912.| THE ORCHID REVIEW. 355 
times laden with seed capsules, while choice varieties growing in shady 
places seldom seeded. It might be due to dust blown on the stigma. 
Mr. R, A. Rolfe wished that someone would conduct a series of 
experiments with Zygopetalum Mackayi in the same way that Mr. Veitch 
did with Cattleya Mossiz. It would then be possible to see whether the 
pollen tubes reached the ovules. He thought not, for the seedlings were 
always pure Zygopetalums, and he believed they were simply developed 
from parthogenetic buds as a result of the stimulus of pollination. 
Mr. Thwaites raised the question whether two or more distinct hybrids 
could be produced from the same seed pod. He thought it had been done. 
The lecturer replied that he thought it possible, and Mr. Crawshay stated 
that he fertilised Odontoglossum Harryanum with both crispum and 
Lambeauianum, and obtained both O. crispo-Harryanum and O. rose- 
fieldiense. Sir Harry J. Veitch said his experience was that if the pollen of 
several species were used only one took effect. Mr. Hatcher spoke of 
using the pollen of both Miltonia vexillaria and an Odontoglossum on 
another Odontoglossum, and the seedlings were different from ordinary 
Odontoglossums. Messrs. J. M. Black, Gurney Wilson, F. J. Hanbury, 
and A. A. McBean also spoke. 
ODONTOGLOSSUMS FROM EDGBASTON. 
SomE time ago an inflorescence of a handsome hybrid Odontoglossum was 
sent from the collection of W. Waters Butler, Esq., Southfield, Edgbaston, 
which is described at page 111 under the name of O. hellemense var. 
Butleri. The seedling was purchased unflowered, and there was a little 
uncertainty as to which of two specified crosses it came from, but we 
thought that the flower indicated O. loochristiense Vuylstekeanum X O. 
crispum Rossendale. Mr. Butler afterwards sent paintings, by Miss 
Roberts, of flowers from both crosses, with a note on their history. The 
seedling sent to us was the second to flower out of a batch of five, three of 
which have now bloomed, and, Mr. Butler remarks, only varied slightly in 
form and colour. The first he had painted, and the painting now sent 
agrees well with the description already given. The plants were purchased 
at the Elmswood sale, at which also Mr. Butler secured five other seedlings 
in one lot, two of which have now flowered, and are said to have been very 
similar. A painting of one of them is also sent, and it shows very broad 
white sepals and petals, the latter well toothed, with eight to ten rounded, 
somewhat confluent cinnamon brown spots, and a round lip with a large 
cinnamon blotch in front of the crest. Mr. Butler states that this batch 
was purchased with the record above given, and as there is a distinct 
resemblance to O. triumphans in the shape of the lip we now think, with 
the two paintings-now before us, that this one must be a form of O.
