distinguished from E. latifoUa ; and incomplete specimens of a new species, distin- 

 guished by its elongated and upwardly thickened peduncles.* 



In Laurinece several Japanese species of Benzoin are analogous to ours and to the 

 Sassafras of Eastern America, as is Machihis to our Persea ; while Tetranthera Jajwiiica 

 has a general analogue on each side of the American continent. 



Houttiij/nia cordata, Thunb., is represented in the southwestern part of North 

 America by Xuttall's Anemiopsis ; as is Saururus Loureirihy oxix eastern S. cernuus, 

 from which it differs only by its short filaments and distinctly pediceUed flowers. 



The Chloranthacece of Japan, &c. have no North American representatives. Chlo- 

 ra7ithus serratus was collected in this expedition. Sarcandra of Gardner and "Wight 

 rests on a character (the total suppression of the lateral anthers) which Brown had 

 long ago indicated as inconstant. S. chloranthoides of Gardner is probably Chhranthus 

 hrachystachys of Blume, and perhaps Brown's C monander. My Tricercandra (which 

 may be Thunberg"s Bladhia glabra, known only in fruit) was rediscovered in abundant 

 and more fully developed specimens. In a single instance, the vestige of an anther 

 was detected upon the middle filament. A second species, from the north of China 

 (communicated by Dr. Hooker), confirms the genus, whUe showing that it rests, not 

 upon the order of the suppression of the anthers, but upon the remarkable form of the 

 stamens. These are deciduous, as in Chhranthus. The style affords a subsidiary 

 character. I append the diagnoses of the two species.f 



EuphorhiacecB. Siebold and Zuccarini's Pachysandra terminalis (sparingly gathered 

 on the mountains northeast of Hakodadi) is a very close (and the only) congener of 

 our P. procutnhens, which is restricted to a narrow district between the Alleghanies and 

 the Mississippi. Goughia NiJgherriensis, Wight, is new to the Japan Flora, &c., but 

 was already kno^^^l at Hong Kong. The rest of the Euphorbiacete are also mostly 

 of Indian or Oceanic types, except two Euphorbia, nz. the E. pahistris of Europe,
