312 EXPEDITION TO JAPAN. 



Stephanandra flexuqsa, Sieb. & Zucc. (in Acad. Monac. 3, p. 70, t. 4.) Spira?a incisa, Thunb. 

 Simoda. A remarkable plant, winch- Thunberg very naturally referred to Spiraea. 



Hydrangea virens, Sieb. & Zucc. Fl. Jap. 1, p. 114, t. 60. A striking and neat species, with 

 very small and narrow leaves, and small cymes bearing few radiate blossoms, or sometimes none 

 at all. "A low bush; sterile flowers greenish-white." 



Hydrangea Hortensia, DC, var. Azisai, & var. Otaksa. H. Azisai, & H. Otaksa, Sieb. & 

 Zucc. I. c. t. 61 & 52. The specimens plainly show that Siebold's two species are only one, 

 and there is no doubt of their being mere forms of the well-known H. Hortensia. The speci- 

 mens were taken from wild plants growing near Simoda. 



Hydrangea hirta, Sieb. & Zucc. Fl. I. c. p. 117, t. 62. Viburnum hirtum, Thunb. Al- 

 though not showy, this is indeed a curious species, from its small and rayless cymes, and its 

 thin, strongly-toothed leaves, which have been well compared with those of Urtica urens. The 

 specific name is far from appropriate, although the young shoots are strigosely hairy. None of 

 the other Hydrangeaceous genera, viz : Cardiandra, Platycrater and Schizophragma were col- 

 lected. 



Deutzia scabra, Thunb. Fl. Jap. 1, p. 185, t. 24; Sieb. & Zucc. Fl. Jap. 1, p. 20, t. 7. 

 Simoda, &c. 



Deutzia crenata, Sieb. & Zucc. 1. c. p. 19, t. 6. Simoda. The specimens of these two species 

 show the distinctions indicated by Zuccarini, though the name of crenata, is not appropriate. 

 The flowers of the present species are larger than those of the last, and the filaments mostly 

 abruptly dilated or lobed on each side below the summit. But the plant we have in cultivation 

 in the United States under the name of D. scabra is D. crenata. The two appear to be confounded 

 in Japan ; and will probably prove to be only forms of one species. 



Sedum lineare, Thunb. Fl. Jap. p. 187. Simoda. A single, imperfect specimen, of which 

 nothing can be made. 



Heracletjem lanatum, Jtfichx. Fl. 1, p. 166. In bloom. Apparently the same as the more 

 hairy form of the species in Oregon, &c. 



Archangelica officinalis, Hoffm. f Simoda, in the sand of the sea-shore. " Eaten by the 

 Japanese." Too young and undeveloped to determine. 



Ccelopleurum Gmeleni, Ledeb. Fl. Boss. 2, p. 361. (Archangelica G-meleni, DC. excl. syn. 

 Apium ternat.) Simoda. In blossom. I have neither specimens nor a full description for com- 

 parison • but I suspect this plant is rightly referred. It has the habit of an Archangelica, and 

 produces inflated upper sheaths, bearing a short, petioled-trifoliolate, or three-lobed leaf, the 

 leaflets or segments ovate, acute or acuminate, and sharply serrate ; and the narrowly linear 

 leaflets of the involcel are remarkably prolonged, exceeding the rays, or sometimes three or four 



times as long. 



Torilis Japonica, DC. Prodr. 4, p. 219? Simoda. 



Osmorhiza longistylis, DC. Frodr. 4, p. 432. 0. Japonica, Sieb. & Zucc. Fam. Nat. Fl. 

 Jap. p. 95. Simoda. Exactly the plant of the United States, exceptthat the styles are rather 

 shorter than usual. Zuccarini distinguishes his 0. Japonica by the obtuse lobes of the leaves, 

 and the pedicels exceeding the length of the fruit. But our present specimens have the lobes 

 equally acute, and the pedicels not longer than the fruit, while they decidedly are so in some 

 New England and other North American specimens. 



Aucuba Japonica, Thunb. Fl. Jap. p. 64. Simoda.
