coloured. Germen sericeous. Aristae villous. Style 
red, very hairy. Stigmas 5, purple and re volute, the 
whole plant has an agreeable scent of Lemon or 
Citron. 
The drawing of this plant was taken at the nursery 
of Messrs. Colvill and Son, where it was raised from 
seed. We suspect it to be a mule between one of the 
smaller Citron-scented kinds, and a species of larger 
growth ; It IS nearer related to P. palUdum than to any 
other described one. A free-growing plant and an 
abundant flowerer, continuing in bloom the greater 
part of the summer; and though the flowers are not 
so showy as in some others, their number and the 
agreeable scent of the plant make it a very desirable 
acquisition. We have named it from the resemblance 
of its leaves to the shells of some species of the genus 
Pecten. It thrives in any light rich soil, or a mixture 
of turfy loam and peat, or decayed leaves, suits it as 
well as any thing. Cuttings root freely, planted un- 
der hand-glasses, or in pots placed in a sheltered 
situation.
