The botanical museum of the Jardin des Tlantes having recently 

 lavoured us with excellent specimens of this singular plant, collected 

 ny M. Farges, with staminate and pistillate flowers, which were 

 wanting when I published the genus, it is desirable that an additional 

 [•''■^te from the new material should be given in ' Icones Plaiitiirum,' 

 ";i which previously only fruiting specimens were represented. 3Ieai_i- 

 i'lme, moreover, Professor Baillon has informed me that Eucommin is 

 i«lentical with his Evjytelea Davvliann, published in ' Adansonia,' xi. 

 (1^75), 305. At the time of publication of Eaconimin I could not 

 venture any serious suggestion as to its affinity. There cannot now, 

 however, be any doubc that its nearest ally is Eiqyl^'ha, although I 

 cannot regard it as rightly referable to that genus, from which it differs 

 >n having an embryo equalling the albumen in length, a solitary ovary 

 With bifid stigma, presenting every appearance of a syncarpous dicar- 

 Pellary pistil, and finally the unique histological peculiarity of its 

 unbranched caoutchouc-containing cells, described by Professor \\ eiss 

 »n ' Lmn. Trans.' ser. 2. iii. 243.* I may point out that in our flowering 

 specimens the staminate flowers are wholly destitute of any trace of 

 <*arpels, the pistillate flowers, which are on a separate specimen, in like 

 naanner show no trace of stamens. Professor Baillon (/.c.) describes
