﻿ON THE BOTAXY OF JAPAN. 383 



It is to be regretted that no Tilia were met with. It would be interesting to know 

 whether the two species mentioned by Zuccarini are of the European or the American 

 type. The genus is absent from Western America. 



Of Ternstroemiacece, Camelliacece, &c., nothing of any novelty was collected, except 

 that Small obtained, from the very northern extremity of Jesso, a species of Acti/iidia, 

 lAndl.' (Trochostigma, Sieb. & Zucc, — a genus manifestly related to Saurauja), very 

 much like the one which Mr. Wright obtained at the northern Loo Choo Islands (and 

 which is certainly both T. rufa and T, arguta of Siebold and Zuccarini), but ap- 

 parently distinct. It needs to be compared with Lindley's original Actinidia callosa, 

 of the Himalayas. 



Geranium erianthum of Fischer, belonging as it does both to Northeastern Asia and 

 Northwestern America, was a discovery to be expected in Japan. It was found at 

 Hakodadi and elsewhere. 



The northern part of Japan also yielded a new Simariibacea* which should how- 

 ever be compared with Planchon's Picrasma ailanthoides, detected by Bimge in North- 

 ern China. 



Of jRiitacece there were collected only one of the four Japanese species of Zanthoxr/- 

 him, Thunberg's Skhmnia Japonica (from the northern end of Jesso), and a plant 

 which, so far as can be told from the fruit, seems to be a new species of the Polynesian 

 genus Euodia.'f 



From Simoda I had formerly received, from Drs. Williams and Morrow, an insuffi- 

 cient specimen of a Coriaria. The fine specimens gathered by Mr. Wright show it to 

 be an entu-ely new species of this peculiar and anomalously distributed genus.J Dr. 

 Hooker takes the Himalayan species for a variety of the European (although Wallich's 

 figure looks difi'erent enough), as he also identifies the New Zealand species with 

 the common one of the Andes. Besides these, there are indications of a species in 

 Mexico.
