﻿412 ON THE BOTANY OF JAPAN. 



Iridacece are represented in the collection by Iris setosa, Pall., J. Imvigata, Fisch. 

 (probably Thunberg's /. versicolor), I. orientalis, Thunb. 1 and a low species whicli 

 appears to be new.* 



Passing to the variously connected tribes which are probably to constitute one great 

 order, Liliacece, I notice a well-marked new species of Smilaa',^ — probably Thunberg's 

 S. Pseudo-China, but not that of Loureiro. It should be compared with 8. Sieholdii of 

 Hasskarl, which is enumerated as from Japan, but not described in any work known 

 to me. The species which I had named S. Japonica in Perry's Expedition is evidently 

 the Linnsean S. China, and perhaps Kunth's Coprosmanthus Japonicus also. I find, 

 indeed, only single ovules in each of the three cells ; but Kajmpfer states that the 

 seeds are four, five, or six, and figures the latter number. I have seen nothing an- 

 swering to Kunth's Heterosmilax Japonica, nor to his Coprosmanthus consanguineus ; 

 the latter may perhaps be one of the forms of the Eastern North American S. ( Copros- 

 manthus') herbacea. Smilax had appeared to be absent from the western portion of 

 the United States, although so abundant in the eastern ; but Hartweg found a species, 

 allied to S. rotundifoUa, in California. 



Paris is a strictly Old-World genus, and our Medeola is its analogue in Eastern 

 North America. From Hakodadi and the vicinity, the expedition obtained Chamisso's 

 rare P. hexaphylla, with seven or eight leaves, — resembling those of Medeola Vir- 

 ginica, the larger ones five inches long, and the cusp of the stamens considerably shorter 

 than the anther : also a new species, closely resembling the European and Siberian 

 P. quadrifolia, but apetalous, with rather broader leaves, and with muticous anthers ! 

 The specific name chosen for it is intended to suggest the resemblance.^ The Japanese
