PLANTS COLLECTED IN JAPAN. 315 



no larger than those of Y. Thunbergiana (of which perhaps it is only a small state with a 

 naked scape) may be provisionally referred to this species. 



Taraxacum Dens-Leonis, JDesf. Simoda and Yokohama. A nearly cosmopolite plant. 



Chorisis repens, DC. Prodr. 7, p. 178. Chorisma repens, Don, in Edlnb. Phil. Jour. Pre- 

 nanthes repens, Linn. Amozn. Acad. 2, p. 360, t. 4. Simoda ; creeping in deep sand on the 

 beach; April. This very rare plant was, till now, known only from Kamtschatka and the 

 Kurile Islands, and has not been gathered, I believe, since the time of Linnasus. In my opinion 

 Don has rightly established a genus upon it, and Ledebour, who had seen the plant, was wrong 

 in referring it to Nabalus, to which, however, it is manifestly allied. The mature fruit is 

 unknown ; but the immature achenia are flat, ribbed with ten narrow and salient nerves, and 

 contracted at the apex into a distinct but short beak. The character of the foliage is that of 

 Nabalus. 



There is also in the collection, from Simoda, a Cichoraceous plant, which I am unable to 

 determine from the present materials. It seems to be allied to Barkhausia, the immature 

 achenia being slender-beaked, but they are apparently compressed ; the pappus is, perhaps, 

 rather sordid and fragile, and the cylindrical small heads are only live-flowered. It is to be 

 hoped that Mr. Wright, in the North Pacific Surveying Expedition, has obtained further 

 materials. 



Sonchus asper, Vill. S. oleraceus, Thunb. Simoda and Hakodadi. Probably the true S. 

 oleraceus also occurs in Japan, as it does in every other part of the world. 



Isolobus radicans, A. DC. Prodr. *l,p. 353. Lobelia radicans, Thunb. Simoda. 



Wahlenbergja marginata, A. DC. Prodr. 7, p. 433. Campanula marginata, Thunb. Dry 

 river-banks. Simoda. 



Campanula Trachelium, Linn.; Thunb. Fl. Jap. 88. Simoda. 



Andromeda (Pieris) elliptica, Sieb. & Zucc. Fam. Nat. Fl. Jap. pars 2, p. 2. Simoda. 

 Probably specifically distinguishable from A. ovalifolia of the Himalayas, but not by all the 

 characters assigned. The style is not more exserted in the Himalayan than in the Japanese 

 plant, and the leaves of the former are by no means always cordate, but sometimes even acute 

 at the base. Those of the present species are sparsely and minutely hairy underneath. 



Rhododendron Indicum, Sweet; DC. Prodr. 1, p. 726. — Simoda and Hakodadi. Several 

 varieties, growing wild. 



Rhododendron Metternichi, Sieb. & Zucc., Fl. Jap., 1 p. 23, t. 9 ? sed stamina 20 ! — Simoda. 

 Cultivated. 



Azalea? serpyllifolia (n. sp.): humile ; ramulis strigosis ; foliis oblongo-spathulatis mu- 

 cronatis parce setoso-hispidis mox glabris impunctatis ; floribus e gemmis plerumque solitariis 

 subsessilibus ; calyce brevissimo ; corolla regulari, lobis amplis tubo infundibuliformi brevi lon- 

 gioribus ; staminibus 5 exsertis declinatis ; antheris basi mucronatis. — Simoda. " Cultivated ; 

 not common ; called by a Japanese name meaning Rice Azalea, on account of its small leaves 

 and flowers." I find nothing like this species described under either Azalea or Rhododendron. 

 The leaves are barely from a quarter to a third of an inch in length, and appear to be deciduous ; 

 and the corolla is only one-third of an inch in length and breadth ; the color not recorded, but 

 probably pink or white. 



Pyrola rotundifolia, Linn. Simoda. Not before recorded from Japan. But Zuccarini 

 enumerates P. media. Our single specimen belongs to a small-leaved form of P. rotundifolia.
