Mr. Miller in his figure of this plant, to which Linn/F,us 

 refers, has been more happy in his reprefentation than in that 

 of many others; Rumphius' figure and defcription accord 

 alfo with our plant, fome of his leaves indeed are more per- 

 fectly three-lobed than any we have feen here on the living 

 plant, and to this variation, he informs us, they are fubjeft. 



We learn from Mr. Miller, that roots of this Arum were 

 brought from Ceylon in the year 1752. It flowers in May 

 and June, and is regarded both by Mr. Miller and Mr. Aitos 

 as a ftove plant ; we have feen it fucceed very well with the 

 treatment of a tender green-houfe plant. 



It is one of the leaft of the tribe ; its root is like that of 

 the common Arum, and extremely acrid : but the plant is 

 more particularly diftinguifhed by the rich, brown, velvety 

 appearance of its flowers ; the length of its tapering fpadix, 

 which on its lower part is full of little cavities, and refemblesa 

 piece of metal corroded by long expofure ; and by the into- 

 lerable ftench which the whole of the flower, but more efpe- 

 cially the fpadix, fends forth. 



It is a native of Amboyna, as well as of Ceylon. RumpjuV 

 informs us that the roots, fomctimes eaten raw by miftake, 

 caufe violent inflammations of the mouth and throat, and that 

 they do not lofe their acrimony even when boiled. 

 The plant increafes freclv by offsets from its roots.
