A. sesquipedale—This extraordinary plant has become 
famous as one of the Orchids which Charles Darwin was 
specially interested in, on account of the exceptional length 
of its spur. The stem is erect, and hidden by the clasping 
bases of the broad, recurved, strap-shaped leaves, which are 
deep green, keeled, 1ft. long, and bilobed at the apex. 
Flowers on axillary spikes—strong plants producing four 
flowers on each spike — ivory-white, 6in. or more across, 
waxy in appearance; the sepals and petals equal, over- 
lapping at the base, narrowed upwards to a point; lip 
large, heart-shaped; spur as thick as a goose-quill, rft. to 
1}ft. long. The flowers are generally produced in the early 
winter, lasting nearly a month; they are very fragrant. 
Native of Madagascar. This noble species requires 
tropical treatment, and abundance of water at the root.
