318 EXPEDITION TO JAPAN. 



Fagoptrum emarginatum, Meisn. I. c.p. 143? Simoda, &c. The specimens too young for 

 proper specific determination. 



Kumex crispus, Linn., var. nudinalvis, Meisn. 1. c. p. 45? Simoda. There are portions 

 of two other Kumices, too imperfect to he determined. 



Benzoin sericeum, Sieb. & Zucc. Fam. Nat. Fl. Jap. 2, p. 80. Hakodadi. I should have 

 taken this for a species of Sassafras. 



Machilus Thunbergii, Sieb. & Zucc. I. c. ? Laurus Indica, Thurib. Fl. Jap. p. 173. Simoda. 

 A tree with a spreading top, sixty feet high. 



Cinnamomum pedunculatum, Nees, Laur. p. 62. Simoda. 



Emiagnus macrophylla, Thunb. Fl. Jap. p. 67. Hill-sides, Simoda. 



El^iagnds umbellata, Thunb. Fl. Jap. p. 66, t. 14. With the preceding. 



El^eagnus pungens, Thunb. 1. c. p. 68? High hills, Simoda. A tiee twenty .feet high. 

 The hranches are not spinescent in the specimens, and the pedicels (of pistillate flowers) either 

 solitary, in pairs, or in fascicles. 



Thesium alpinum, Linn, f Simoda and Yokohama. 



Euphorbia Helioscopia, Linn. Yokohama. Also another species too imperfect for determi- 

 nation. 



Hottuynia cordata, Thunb. Fl. Jap. p. 144, t. 26. Simoda. 



Saururus Loureiri, LJecaisne in Ann. Sci. Nat. ser. 3, 3, p. 102; Sieb. & Zucc. I. c. S. 

 cernuus, Thunb. Fl. Jap. p. 154. Distinguished from our S. cernuus hy the short filaments, 

 as indicated hy Decaisne ; also hy the distinct pedicels, which are spreading or reflexed after 

 flowering, and by the larger and rounded hractlet they hear at their summit. 



Piper futukadsura, Sieb. in Fam. Nat. Fl. Jap. 1. c. p. 107. Simoda. 



TRICERCANDRA, Nov. Gen. Chloranthacearum. 



Flores hermaphroditic achlamydei, spicati, singuli intra hracteam navicularem sessiles. 

 Stamina 3, hasi leviter coadunati ovario supra hasim antice inserta, asqualia, loriformia, inter- 

 medium anantherum, lateralia hasi extus antheram unilocularem adnatam ohlongam longitu- 

 dinaliter dehiscentem gerentia. Ovarium ovatum, intus gibbum, uniloculare : stylus brevis : 

 stigma magnum, capitato-depressum, vix emarginatum. Ovulumorthotropum, sub apice cavi- 

 tatis appensum. Fructus haud visus. — Herba Japonica, ut videtur perennis, spithamasa, caule 

 simplicissimo inferne aphyllo ad nodos bisquamato, apice quadrifoliato atque spicam ohlongam 

 pedunculatam simplicissimam gerente, stipulis interpetiolaribus parvis. 



Tricercandra quadrifolia. — Hakodadi and Yokohama ; on steep and shaded hill-sides ; March 

 20. Stem erect, rather stout, four to six inches high, the naked part having one or two nodes, 

 each bearing a pair of small and bract-like scales in place of leaves ; at the summit hearing 

 four leaves in an apparent whorl, but they evidently consist of two approximate pairs. 

 Leaves oval, short-petioled, membranaceous, about two inches long, veiny, tipped with a nar- 

 row acuminate point, strongly serrate with sharp-pointed teeth. Peduncle terminal, about an 

 inch long. Spike half an inch or more in length, dense, squarrose with the long and spread- 

 ing tail- like stamens. Bracts navicular, triangular, shorter than the ovary. Rhachis more or 

 less excavated above each bract. Stamens inserted on the back of the ovary, opposite the sum- 

 mit of the short bract ; similar, except the middle one is wholly sterile, porrect, or soon some- 

 what decurved, becoming three lines long, apparently greenish, rather fleshy, narrowly ligulate, 

 obtuse, the edges apparently vertical ; the two lateral bearing a linear-oblong, adnate, one-celled
