306 EXPEDITION TO JAPAN. 



urination, but they nearly accord with Thunherg's and Zuccarini's descriptions. The flowers 

 resemble those of C. Viorna in size and shape, but the sepals are not so thick and leathery ; and 

 the peduncles are fully as long as the petioles. 



Clematis Williamsii (n. sp.) : sericeo-pilosa ; foliis ternatisectis ; foliolis supra laxe glabratis 

 oblongis vel cuneato-ovatis inciso-trilobatis, lobo interrnedio acuminate, lateralibus nunc inciso- 

 dentatis ; pedunculis solitariis folio brevioribus basim versus bibracteatis ; staminibus sepalis 

 orbiculatis paullo brevioribus, filamentis ligulatis glabris ; ovariis stylisque villosissimis. 

 (Simoda, April 20 ; in flower. " A vine on the ground.") — This belongs to De Candolle's 

 section Gheiropsis, and ranks with C. Nipalensis and C. montana, of the Himalayas, but is 

 clearly different from both. The blossom is about an inch and a half in diameter when the 

 (apparently purplish or bluish) sepals are fully expanded. The filaments are linear-ligulate 

 and much broader than those of C. montana, and the anthers shorter. The bracts are small 

 (barely 2 lines long) and distinct. The leaflets are not serrate, but mostly incisely three-lobed 

 above the middle, and often the lobes of the lateral ones again sparingly incised or 2-3-toothed. 

 All the leaflets are short-petiolulate, and are rounded or roundish at the base. The species is 

 named for one of the collectors, S. Wells Williams, Esq., of Canton, a cherished friend and 

 correspondent, author of one of the best works that have appeared upon the Chinese empire, and 

 a good naturalist, as well as a learned oriental scholar. 



Anemone Baikalensis, Turcz. Cat. Baikal; Ledeb. Fl. Boss. 1, p. 17; Sieb. & Zucc. I. c. : 

 var. ? laevigata. Hakodadi. The base of the stem and the radical leaves were not gathered. 

 It is doubtless the plant referred by Zuccarini to A. Baikalensis, and accords with his notes ; 

 but the foliage is nearly or quite glabrous. Its relationship to A. narcissiflora is evident, not- 

 withstanding the elongated and few pedicels, and the pubescent achenia. 



Ranunculus selebatus, Linn. Simoda ; in rice fields. Zuccarini notes that his Japanese 

 specimens exhibited globular heads of carpels ; in these the heads are elongated in the usual 

 manner of the species. 



Ranunculus teknatus, Thurib. Fl. Jap. p. 241 ; Sieb. & Zucc. 1. c. p. 71. 



Ranunculus Japonicus, Ihurib. ? Not the plant so named by Zuccarini. The specimen is 

 incomplete, but it very nearly accords with an Oregon plant, gathered by Mr. Spalding and by 

 Geyer (No. 380,) which Sir Wm. Hooker makes a variety of R. Pennsylvanicus, with more 

 slender and diffuse stems, and, I may add, with more beaked carpels collected in a broader and 

 shorter head. From R. Chinensis it is distinguished by the flat and margined achenia, not tri- 

 costate on the back. 



Ranunculus repens, Linn. ? Hakodadi ; May. The specimen (in flower only) appears to be 

 the same as what in North America is called a large form of R. repens. 



Caltha palustris, Linn. Hakodadi. Both the small-flowered form, mentioned by Zuccarini, 

 and also with large blossoms. 



Isopyruji Japonicum, Sieb. & Zucc. 1. c. p. 73. Yokohama, and also Simoda ; on stone walls. 

 The four (or occasionally three) carpels, when ripe, are not " erect-connivent," but widely 

 divergent. The root resembles a small tuber. 



Aquilegia flabellata, Sieb. & Zucc. 1. c. Hakodadi. Remarkable for the great size of the 

 sepals, and for the short, circinate, included spurs of the petals. 



Glaucldium palmatum, Sieb. & Zucc, I. c, p. 76, t. 1, B. Hakodadi. The scanty specimens 

 are only in blossom, like those of Siebold, and throw no additional light upon this singular 

 genus. I should take the perianth to be simple, and of the nature of calyx.
