The remarkable Cirrhopetalum which forms the subject 
of our plate is a native of Siam, where it was found, 
near Panga, by Mr. Curtis, with whom it flowered in the 
Botanic Garden at Penang in October, 1893. It was first 
described, some three years later, by Mr. H. N. Ridley, 
Director of the Singapore Botanic Garden. A plant of the 
species was received at Kew from the Malay Peninsula in 
1894. It would appear to be shy of flowering, for it has not 
yet done so at Kew, though a plant in the collection at the 
Royal Botanic Garden, Glasnevin, did so in July, 1903, 
and another in that of Sir Trevor Lawrence, at Burford, 
flowered in November, 1909. The figure of the inflores- 
cence here depicted was prepared from Sir Trevor 
Lawrence’s specimen sent for identification to Kew; that 
of the leaves, pseudobulbs and rhizome has been taken from 
Marcg, 1911.
