The genus Thomsonia is so very closely allied to Amor- 

 phophallus that it might very well be reduced to a section 

 of the latter, differing only in the tuberculate appendage 

 of the spadix, the tubercles being merely arrested male 

 flowers. Only one species is known, though another, T. 

 Hookeri, Engler, 1. c. p. 307 (Allopythion Hookeri, Gen. 

 Aroid. p. 24, t. 24) was founded by Schott on a very bad 

 specimen of a spathe collected by me in the Khasia hills, 

 and the leaf of probably another plant altogether. The 

 name Thomsonia was given by Dr. Wallich, in honour of 

 the late Dr. Anthony Todd Thomson, Professor of Materia 

 Medica in University College, London. 



* The P. Wallichianum, Kirtikar, in Journ. Bomb. Nat. Hist. Soc. vol. vii.

 Amorphophallus commutattix and foliage of another plant.
