general habits, but it differs from the latter by its distinctly nerved utricle, smaller 

 seed and oblony-ovate scale, and also by the shape of the utricle.

The plant is easily distinguished from A. japoiiicum by the shape of the 

 appendage of the spadix and also by the shape and colour of the s[)athe. The 

 appendage is stouter and c^'lindrical-clavate with rounded ape.x, truncate at the 

 base and olten pmplish below, and is provided with a short stalk. In the spathe, 

 the tubular i^art is about one half the length of the lamina, which is dark-purple 

 in colour. The tubular part as well as the lower portion of the lamina is paler 

 coloured with many whitish or light-yellowish longitudinal streaks. 



According to Mr. F. C. Greatrex, British Vice-Consul at Hakodate and an 

 enthusiatic botanist, the plant is said to be very common in the vicinity of Hako- 

 date. It likes to grow in open situations, and its corms grow much deeper in 

 the soil than in the case of those of A. j'aponicum. 



Dr. H. Takeda found a specimen of this plant in the Kcw Herbarium collect- 

 ed by Ma.ximowicz at Hakodate in the year 1861, named Arisaema japoiiicum Bl. 

 var atropurpuremn Engl. According to him, there is also another specimen of 

 the same species at Kew collected at the same locality by Hodgson in i860.
