PIPER—BERBERIS AQUIFOLIUM AND BERBERIS REPENS. 449 
from the left-hand specimen on the type sheet, but with some minor 
errors as regards the small leaf below the inflorescence. It seems 
highly probable that the separate leafilet of the plate was drawn 
from the one missing on the lower leaf of the type specimen. In 
form and dentition it agrees extremely closely with its probable 
mate still on the specimen, so closely indeed as to suggest that it 
may be the same reversed and drawn to show the underside. Dr. 
Gray apparently reached essentially the same conclusion when he 
wrote, “ Pursh could not have taken his separate leaflet from this— 
but doubtless from the other specm. in herb. Lamb. on the same 
sheet.” The very close similarity of Lewis’ specimen and Pursh’s 
plate should be convincing that Lindley was in error when he as- 
serted that Pursh’s illustration was drawn wholly from Menzies’ 
specimens in the Banksian Herbarium. This is also supported by 
the criticism in British Flower Garden,” previously quoted. It is a 
remote possibility that the two complete leaves on Pursh’s type sheet 
are from some other collection than Lewis’s, but such an assumption 
in the lack of evidence is gratuitous. 
It further may be again mentioned that it is extremely doubtful 
if there ever was a Menzies specimen in the Banksian Herbarium, 
so that Lindley apparently meant either the Nelson specimen in the 
Banksian Herbarium or the Menzies specimen in the Lambert Her- 
barium. 
In Pursh’s original description of the two species occur some 
statements which still remain questionable. These descriptions need 
to be considered in the light of the following paragraphs from the 
preface of his book. 
“The descriptions of those plants, as far as the specimens were perfect, I 
have inserted in the present work in their respective places, distinguishing 
them by the words v. s. in Herb. Lewis. Several of them I have had an 
opportunity of examining in their living state, some being cultivated from 
seeds procured by Mr. Lewis, and others since my arrival in England from 
seeds and plants. introduced by Mr. Nuttall.” (p. xi.) 
“ Perfect seeds from the last-mentioned tree [Osage apple] were given by 
Lewis to Mr. MeMahon, nursery and seedsman, at Philadelphia, who raised 
several fine plants from them, and in whose possession they were when I left 
America.” (p. xii.) 
“ Besides these general collections, there were a number of interesting new 
plants in the Banksian Herbarium collected by different persons in North 
America. Among them I found a number of those collected by Archibald 
Menzies, Esq., during the famous expedition under Vancouver, on the north- 
west coast of America. As several of them had been described by me from 
the Lewisian collection, I requested permission of Mr. Menzies to adopt such 
as were immediately connected with my plan, which he very obligingly com- 
plied with. (p. xvii.)
