Obs. 1. — Tbe stem is almost always buried under a mass 

 of earth and rubbish, in which lie the fruiting spadices, a 

 position favoured by the peduncle being very much 

 shortened by its repeated flexures. May not this habit (not 

 shared in by any other species that I am acquainted with) 

 favour the development of the seeds, as in Trifolium sub- 

 terranetim, Arachis hypogoia, &c. ? On one occasion I found 

 a specimen about 3 feet high, bearing spadices with 

 mature fruit, though its stem was clear of the usual accu- 

 mulation. The large number of spadices occurring in 

 nearly the same stage of development is also remarkable. 

 On one plant I found fourteen spadices, the lower ten 

 bearing fruits, the others flowers.
