ON SOME MOUNTAIN PLANTS- FROM NORTHERN CHINA, lol 



Viola {Nomwiium) acuminata, Led. Regarded by Kegel as a variety 

 of F. canina, Linn. " Fleurs a pen prbs blanches." 



Viola {Dischidium) biflora, Linn. On the summit of Po-hua-shau. 



Xanthoxylon Bungei, Planch. "J'euai vu des arbres de trente 

 pieds et plus, au pied du Po-hua-shan." 



Evomjmus Thunhergianus, Bl. (Rgl. Tent. fl. Ussur., t. vii., figs. 

 1 — 4.) The present specimen, as well as others from Jehol (David) and 

 Nagasaki ( Maximo wicz), has the branches destitute, or almost so, of 

 wings, and would fall under Kegel's variety /? apterus ; but I doubt 

 the constancy of this character : — The species extends at least as far 

 south as the hill country around Ningpo, and there the wings are 

 sometimes greatly developed, as shown in a specimen sent me for 

 determination by Mr. Swinhoe, for whom I learn that, on account 

 of this peculiarity, the shrub is usually called by foreigners, in whose 

 gardens at Shanghai it is cultivated for ornament and as a curiosity, 

 by the name of ** Cross-tree." 



Rhamjius {Eurhamnus) argiita, Maxim. (Maxim. Rhamn. Orient. 

 Asiat., tab. icon, plant, opt. cum figs. 48—51 analyses exhiben- 

 tibus.) The specimens are male, and enable me to add something to the 

 original character: — Floribus masculis femineis similibus pedunculis 

 2-3plo tantum brevioribus, petalis spathulato-oblongis enerviis 

 staminibus ad medium loborum calycinorum attingentibus vix 

 superatis. I have specimens with not quite ripe fruit from Jehol, 

 gathered by Father David. 



Aceris sp. ''J'envoie les fleurs avec les jeunes feuilles, qui 

 eteaint toutes rouges. Je n'ai pasremarque cela sur les jeunes feuilles 

 d!Acer truncatum que nous avons chez nous a Pekin. Nom chinois 

 Shaij-mu^ The leaves as they reached me had no tinge of red. The 

 flowers dried of a dull deep yellow, and were smaller than those of 

 A. truncatum, Bge., which also dry of a milk-white hue; but this 

 difference may depend on the amount of care bestowed in the prepa- 

 ration of specimens. I think, however, that those sent are most 

 likely referable to A. Mono, Maxim., though they are insufficient to 

 justify a decided judgment. 



Indigofera {Euindigofera) Bungeana, Steud. A plant sent by 

 Maximo wicz from Yokohama, where it is said to be common, and 

 ticketed /. decora, Lindl., is identical with this, which Dr. S. W. 

 Williams has also gathered at Peking. According to Pentham, Lind- 

 ley's species, of which I have seen no authentic specimens,' has 

 flowers larger than those of /. venulosa, Champ., and leaflets 1^ to 2 

 inches long. In none of the specimens of the present plant are the 

 fully expanded flowers more than 3^ lines long, nor do the largesit 

 leaflets exceed 7 lines. 



Caragana frutescens, DC. 



Caragana microphylla, DC. Leaflets flaccid, without prominent 

 veins, canescent, and less cuneate in shape than in a specimen gathered 

 at Kiachta by Dr. Calau ; but I think there is no doubt of their 

 specific identity. 



Prunus (Cerasus) Padus, Linn. 



Primi sp. " Petit arbrisseau . Les specimens que je vous envoie 

 ont e'te coupes au niveau de la terre." This piant is identical with 

 one gathered by Mr. De Grijs in December, 1862, on the summit of 



K 2
