PLANTS COLLECTED IN JAPAN. 307 



P^eonia officinalis, Linn. (P. albiflora, Pall. Fl. Boss. t. 84 ; but the petals are red or purple.) 



Illicium religiosum, Sieb & Zucc. Fl. Jap. 1, p. 5, t. 1. This is the false Star-Anise, with 

 fruit nearly destitute of anisate aroma, and which was distinguished specifically by Siebold and 

 Zuccarini. 



Burgeria obovata, Sieb. & Zucc. Fam. Nat. Fl. Jap., I. c, p. 79. Hakodadi. In blossom 

 only, so that the generic characters are not determinable. The twigs of the specimens, when 

 split, exbale the odor of camphor- wood. 



Akebia quinata, Decaisne, Mem. Lardiz. ; Sieb. & Zucc. Fl. Jap. 1, p. 143, t. 77. A frag- 

 ment only, in flower, was gathered at Simoda, and another on Webster Island, in April. 



Akebia lobata, Decaisne, I. c. ; Sieb. & Zucc, I. c, t. 78. From the variation observable in 

 the leaflets, I should not hesitate to unite A. quercifolia with A. lobata, and probably A. cle- 

 matifolia is not distinct from it. 



Stauntonia hexaphtlla, Decaisne, I. c. ; Sieb. & Zucc, I. c, t. 76. A few flowering speci- 

 mens in the collections. 



Nandina domestica, Thurib. Fl. Jap., p. 9 & 149. In hedges and in wild places. 



Berberis vulgaris, Linn. ; Thunb. Fl. Jap., p. 146. B. Sinensis, Desf. ? ex Sieb. & Zucc, 

 I. c Hakodadi. "A large bush in a hedge ; May 31." This seems to be exactly the com- 

 mon Barberry as introduced into the United States. 



Berberis Thunbergii, DC. Prodr. 1, p. 106. Hill-sides, Simoda ; April 20. This certainly 

 looks like B. Cretica, to which Thunberg referred it, and which Drs. Hooker and Thomson 

 regard as an extreme form of B. vulgaris. 



Papaver somniferum, Linn. Probably an introduced plant. 



Chelidonium majtts, Linn. Hakodadi. 



Dicentra spectabilis, DO. Syst. 2, p. 110. Eucapnos spectabilis, Sieb. & Zucc. I. c. Hako- 

 dadi ; in gardens. The handsome species now common in cultivation ; one of the finest of our 

 many valuable acquisitions from Japan. 



Corydalis inctsa, Pers. Ench. 2, p. 269. Fumaria incisa, Thunb. Hakodadi and Yokohama. 



Corydalis heterocarpa, Sieb. & Zucc, I. c, p. 65. Simoda. 



Corydalis pallida, Pers., I. c. Fumaria pallida, Thunb. Simoda ; on old garden walls, &c. 



Nasturtium palustbe, DC. Simoda. 



Nasturtium officinale, R. Br. Hakodadi and Yokohama. " Sides of fields near the 

 shore." This wide-spread species, the common Water-Cress, is enumerated by Thunberg in 

 his Japanese Flora. In place of the former species, Thunberg and Siebold mention N. am- 

 phibium, but our specimens clearly belong to N. Palustre. 



Turritis glabra, Linn. Simoda. (Not in Siebold and Zuccarini's enumeration.) 



Arabis hirsuta, Scop. Turritis hirsuta, Linn. ; Thunb. Fl. Jap. p. 260. Simoda. As far 

 as can be judged from the single and incomplete specimen, this appears to be a form of A. hir- 

 suta, and it is doubtless Thunberg's plant. Siebold and Zuccarini do not mention it. 



Arabis alpina, Linn., var. ? Japonica : caule validiore (spithamajo ad subpedalem) plurifo- 

 liato ; racemo densifloro ; siliquis plurimis etiam confertis. — Barren sandy beach, also on rich 

 hills, Simoda ; and dry sand of the seashore, Shirahanna, near Simoda ; April 19-20 ; also 

 Hakodadi. The fruit is only half grown, and the seeds not formed. The ripe siliques will be 

 likely to furnish cbaracters which (along with tbe generally stouter and more leafy stems, and 

 the much more numerous flowers,) will distinguish this plant specifically from A. alpina. It 

 is probably abundant, as numerous specimens were collected at several stations. 



Arabis lyrata, Linn, f Hakodadi. The pods are immature, but if the specimens had been
