PLATANTHERA CHLORANTHA WITH THREE SPURS, 393 
deseribed, mostly formed by the labellum taking the shape of the paired 
petals, the flower being consequently spurless. In most instances there 
were also three fertile stamens— the outer. Once only I observed another 
kind of peloria, in which the paired petals were elongated and similar to 
the labellum, but without spurs.” ОЁ P. chlorantha he records two instances 
-of spurless peloria, but no other form of peloria. Spurless labellum peloria 
he also records for Platanthera ciliaris, P. fimbriata, and Р. hyperborea.

Back view of a flower with equal spurs, about twice natural size. 
The exact locality of Mr. Woodruffe-Peacock’s specimen is unknown, 
but it was presumably taken somewhere in the neighbourhood of Bath, 
as it is accompanied by the following undated note :— 
4 Queen's Canal, Bath, 
“I am sending an orchid which I thought might be of interest, each 
flower has three spurs instead of one. Т am afraid I have kept it too 
long to be of much use. 
(Signed) SUSAN ALLETT." 
The flowers of the present specimen are somewhat smaller than those of 
P. chlorantha ; the sepals being only about 1 cm. long and the spurs 
2:3 em. long. 
I have no explanation to offer as to the cause of this metamorphosis.
