SCIENTIFIC NOTES 
MALFORMED CYPRIPEDIUMS. 
At the Scientific Com- 
mittee meetino- of the 
Royal Horticultural 
Society on March 8th, 
I g I o, Mr. Lionel 
C r a w s h a y s h o w e d 
drawings illustrating 
the malformations 
shown in the twin- 
flowered inflorescence of 
Cypripcdiiiin barbatinn from Lord Avebury, 
exhibited at the last meeting. He remarked 
that the two-flowered scape had branched 
about the middle. The terminal flower (Fig. 
A) had a ccmplete perianth except the label- 
lum, which was absent, its only indication 
being a median streak in the anterior sepal. 
The column was formed of two normal 
anthers and twO' staminodes, the stigmatic 
plate being absent, and its place being 
occupied by the anterior staminode. The 
ovary contained two placentas placed opposite 
to one another. The 
lateral flower (Fig. B) 
was normal in every way 
except in the trimerous 
outer whorl of the peri- 
anth, which showed re- 
version to the primitive 
type, the three segments 
^ being divided to the base. 
The ovary contained only 
J3. one placenta, placed 
anteriorly.
