The genus Arissema comprises between fifty and sixty 

 described species, chiefly inhabiting temperate and sub- 

 tropical Asia. One occurs in Abyssinia, and a few. are 

 natives of North America, southward to Mexico. Some of 

 the species are amongst the most graceful and elegant 

 members of the order, presenting great variety in the 

 foliage, and more especially in the form and shape of the 

 spathe and spadix, and several have been figured in this 

 work. In some species, A. concinnum (tab. 5914), for 

 example, the spathe is prolonged into a long slender tail ; 

 in A. curratum (tab. 5931) the spadix is elongated; in 

 A. fimbriatum (tab. 7150) it is plumose. A. costatum has 

 both spathe and spadix elongated. A. Griffithii (tab. 

 6491) and A. sjpeciosum (tab. 5964) may be mentioned as 

 representatives of the more showy, ornamental species. 



A. japonicum is apparently very common in Japan, as it 

 is represented in almost every collection of dried plants 

 from that country. It also occurs in Formosa, and Dr. A.
