APRIL, 1922.] THE ORCHID REVIEW. 103 
six inches high, the sepals pinkish on the back, and yellowish in front, the 
petals yellowish on both sides, the lip longer than in Gymnadenia 
conopsea, pink at the sides and yellowish-white in the centre, and the spur 
shorter than the ovary. — 
Form C. This is only known from a single specimen with a spike 16 cm. 
in length. The flowers have blunt, pale-green sepals, and rose-lilac lip 
and petals. The spur is very small, as in Coeloglossum viride, or even 
smaller. The flower is scented, but differently from Gymnadenia conopsea. 
The lip is outlined in fig. C, 1 and 2. The figure of the whole spike is 
reproduced from a pen and ink drawing of the living plant by T. A. 
Stephenson. 
A comparison of the forms shows that in form of lip A and C approach 
nearer Gymnadenia conopsea, but B nearer Coeloglossum viride. As regards 
the spur, A even exceeds Gymnadenia conopsea, B is intermediate, and C is 
like Coeloglossum viride. In colour, A and B blend the parent-colours, but 
B with the tints of A roughly reversed, whilst C has the green sepals of 
Cceloglossum viride and the purple lip and petals of Gymnadenia conopsea. 
In the height of the plants, A is intermediate, B is short and C tall. 
We should like to adda brief tribute to the memory of Mr. R. F. Burton, 
who discovered the plant now first described. He passed beyond the veil 
on January 7th, at the age of 57, after a trying illness which lasted three 
years. He was an expert botanist and entomologist ; as a botanist, specially 
interested in the culture of plants and their naturalisation in this country. 
He was most interested in British Orchids and highly successful in their 
cultivation. If he had published the results of his work his name would 
have been well known. As it is, he somewhat shrank from this, but was 
always most willing to place all his knowledge and skill at the disposal of 
other students in the field. At one time he travelled in the East, and Capt. 
Monckton’s “‘ Last Days in New Guinea” is dedicated to him. His most 
important work was in the study of insects and their parasites, especially 
of malaria-carrying mosquitos, with a view to the prevention of disease. 
Much of the data he collected has been published in the reports of the 
Local Government Board, on Public Health and Medical Subjects, and in 
a Handbook of British Mosquitos, by W. D. Lang, published by the 
Trustees of the British Museum in 1920. 
Orcuip Patntincs.—At the meeting of the Royal Horticultural Society, 
held February 28th, a Silver Grenfell Medal was awarded to Mr. T. A. 
Stephenson, M.Sc., of Aberystwyth, for an exhibit of excellent water-colour 
drawings of British Orchids, comprising species and hybrids. A few 
European varieties were also shown.
