of your sample with some s])ccimens of either of them. Of 

 the four fa^^tid gum resins above referred to, it certainly ap- 

 jiroaches Galbanum the nearest." 



From this it is I think clear, that the species in question, 

 if not the origin of Galbanum, must be very near it. Now 

 its fruit has no resemblance to that called Galbanum by Pro- 

 fessor Don, and in fact the plant itself is new to science. 

 At first I took the specimens for a new kind of Opopanax, 

 supposing my fruit to be very young ; for they are in no small 

 degree like that of Opopanax shortly after flowering; but 

 when I found them containing solidified albumen, no doubt 

 could be entertained of their being in nearly a perfect state. 

 This plant, instead of being a neighbour of Ferula and Opo- 

 panax, must be stationed somewhere in the neighbourhood of 

 Smyrnium, from all whose related genera it is essentially dis- 

 tinguished by the surface and vittas of the fruit. The following 

 name and character are what I would propose for its future 

 designation.
