According to specimens in the Herbarium of Kew, 
A. ungulifolia is a native of Borneo, where it was dis- 
covered by Messrs. Motley and Barber in the province 
of Labuane. It is very distinct from any hitherto pub- 
lished species, and probably unique in the presence of two 
curious swellings in the dorsal surface of the saccate base 
of the perianth. These swellings correspond to depres- 
sions with ciliate margins in the inner surface of the same 
sack, and are presumably concerned in the pollinisation of 
the plant by insects. The Indian ally of A. ungulifolia is 
A. indica, Linn., a frequent plant all over tropical India. 
A. ungulifolia was first described by Dr. Masters, 
F.R.S., from specimens exhibited in 1880 at the Exhibition 
of the Royal Horticultural Society, South Kensington, by 
Mr. Mortimer, gardener to Major Storer, Purley Park, 
Reading. he specimen here figured was received at the 
Royal Gardens, Kew, from H. N. Ridley, M.A., F.L.8., 
Director of Gardens and Forests, Singapore, in November, 
1894, and which flowered in a stove in the following 
November. :
