LARDIZABALACEAE. — SARGENTODOXA 351 



Sargentodoxa resembles in its foliage so closely Sinofranchetia, that Oliver de- 

 scribed the flowers of this genus and the fruits of Sinofranchetia as l)elonging to the 

 same species. The fruits, however, are so entirely different from all other members 

 of the Lardizabalaccae, that this new genus can only be retained in its present place, 

 if the characters of the family are considerably amended, or it must be made the 

 type of a new family, but as long as the pistillate flowers are not known, it may be 

 safer to leave it with the Lardizabalaccae as an anomalous genus which has the 

 number of ovules in each carpel reduced to one and the number of carpels multi- 

 plied. Though we have not seen the pistillate flowers, we are convinced that aside 

 from the sexual organs they do not present marked differences, as the inflorescences 

 are exactly alike. The characters of the young carpels we described from unde- 

 veloped carpels which we found on the torus of the fruit between the mature 

 carpels; they also show that the young carpels are at first sessile and that the 

 remarkable long stalk develops while the carpel grows to maturity.
