Conx^er:^ing Keteleeria Carrieke, A Genus of 



Conifers. 



By J. G. Lemmon. 



Dr. Maxwell T. Masters, editor Ourdener's Chrouick, Lon- 

 don, ill an article published April, 188G, reviewing several 

 species of the genns Abies, describes anew from abundant 



Mr. Murray first in 1862 Picea Fo> 



Abies Fortunei. Certain characters are enumerated by Ur. 

 Masters, viz.: " Cones erect (they are figured in his paper as 

 arreet becoming erect), peduucled, thickly grouped and stand- 

 ing like rows of soldiers on the branches (hence they must 

 be persistent from year to year), the scales are persistent," 

 etc. The seeds are shown as devoid of resin vesicles and not 

 at all covered on the inner surface by the recurved wing-base. 

 Dr. Masters also figures a section of the bark and states 

 that "it is thick, spongy and at length cracked like the bark 

 of the Cork Oak," adding the general statement, " Mr. For- 

 tune speaks of it as a magnificent tree with the habit of a 

 Cedar of Lebanon." 



The description and figures show that this singular Chinese 

 tree is no Abies at all but the type of a distinct genus. To 

 crowd It into either Picea as Mr. Murray at first did or into 

 Abies as he did a year later-followed now by Dr. Masters^ 

 requires important changes in the circumscription of two com- 

 pact genera which as commonly received perfectly cover, each, 

 a large number of species.
