﻿ON THE BOTANY OF JAPAN. 385 



are only four, and the ovary indicates a smooth fruit. Blume mentions a second Japan- 

 ese species, which would appear to resemble the ^. jiarviflora [JE. macrostachya, 

 Michx.) of our Southern United States. I am not at present competent to elucidate 

 the affinities of the numerous Japanese Maples. But Acer pictum is apparently an 

 analogue of A. saccharinnm, and A. Japonicum is much like A. circinattim of Oregon. 

 I have not seen the Negtindo mentioned by Siebold and Zuccarini. 



Polygala Japonica in habit is similar to P. Californka, Nutt. (P. cucullata, Benth.), 

 which is probably P. Nutkana, DC, and the only species known in Western North 

 America. 



Leguminosce. Mr. Wright's specimens, and other materials, now enable us to cir- 

 cumscribe the characters and the geographical range of Thermopsis fdbacea, DC. This 

 species extends from the southern extremity of Japan, and even from the islands be- 

 tween it and the Loo Choo group, the shores of the Okotsk Sea, and the Kurile 

 Islands to Oregon, California, and eastward to the Rocky Mountains in New Mexico. 

 It includes the T. macropht/lla, var. of Ton*. & Gray's Flora ; and Nuttall's T. montana 

 is no more than a variety of it. T. rJiombifoUa, Nutt., east of the Rocky Mountains, 

 if the characters hold, is distinguished by its smaller size, and the recur\"ed, strongly 

 falcate legumes. The real T. macrophylla, of Hooker and Amott, may be known by 

 its woolliness, and by the oblong-lanceolate, very villous legumes, nearly sessile in the 

 calyx. Of this, T. Caroliniana of the Southern Alleghanies is the Eastern representa- 

 tive. On the other hand, Japan is the northeastern limit of the European, Himalayan, 

 and Australian Lotus corniciilatus. 



The name of Astragalus lotoides is attributed by De Candolle to Lamarck, instead of 

 to Pallas. 



Mr. Wright gathered the Siberian Orohus Jathyroides in the northern part of Japan, 

 in one instance with the seta replaced by a regular terminal leaflet. Also, Lathyrus 

 pahistris, L. maritimiis, and the Vicia,'* which in Perry's Expedition I called T^ Orohus? 

 It is not that species, however, nor any described one, unless it be Turczaninow's V. 

 pallida. The glabrate form much resembles V. Americana (which, including V. Oregana, 

 Nutt., ranges from the Atlantic to the Pacific), but it wants the conspicuous villous 

 tuft of the stigma.
