. a foot to 18 inches high and as large as a goose quill; it is simple and erect. 
Its leaves are cauline and spredding. The leaflits are joined and oppositly 
poinnate 3 par and termonateing in one, cessile widest at the base and 
tapering to an accuminated point, an inch and } the greatest width, and 34 
inches in length. Each point of their crenate margins armed with a thorn 
or spine, and are from 13 to 17 in number. They are also veined, glossy, 
crinated and wrinkled; their points obliquely. pointing towards the extremity 
of the common footstalk. 
“The stem of the 2nd is procumbent, about the size of the former, jointed 
and unbracated. Its leaves are cauline, compound and oppositely pointed; 
the rib from 14 to 16 inches long and 1 inch wide. The greatest width 3 
inch from their base which they are regularly rounded, and from the same 
point tapering to an accute apex, which is mostly but not entirely termonated 
with a small subulate thorn. They are jointed and oppositely pointed, con- 
sisting of 6 par and termonateing in one (in this form.) sessile, serrate, or 
like the teeth of a whipsaw, each point terminating in a small subulate spine, 
being from 25 to 27 in numb; veined, smooth, plane and of a deep green, their 
points tending obliquely towards the extremity of the rib or common foot- 
stalk. I do not know the frute or flower of either. The 1st resembles a plant 
common to maney parts of the United States called the Mountain Holly.” 
The drawings of the leaves by Lewis are good and unmistakable 
and together with the descriptions show clearly that the first of the 
two species described is Berberis aquifolium, the second B. nervosa. 
Clark copies Lewis’s descriptions verbatim in his journal of the 
same date. 
Further references to these plants occur in the journals only as 
follows: 
April 2, 1806, when camped on the north bank of the Columbia 
opposite the mouth of Sandy River: 
“and the several evergreen shrubs have seased to appear except that species 
which has the leaf with a prickly margin.” 
April 9, 1806, on the Columbia River above Multnomah F alls, 
camped that night opposite Brant Island near the foot of the Cas- 
cades of the Columbia: 
“The vineing honeysuckle has put forth shoots of several inches, the dog- 
toothed violet is in blume as is also both the species of the mountain holley.” 
April 12, 1806, camped at foot of Cascades or Grand Rapids: 
“Near the river we find the cottonwood, sweet willow, broad leafed ash, 
a species of maple, the purple haw, a small species of cherry; purple currant, 
goosberry, red willow, vining and whiteburry, honeysuckle, huckleburry, saca- 
commis, two species of mountain holley, and common ash.” 
This is the last mention of “ mountain holley ” in the journals and 
written at the place where Lewis collected his specimens. From a 
study of these notes it is clear that Lewis had not seen either species 
in fruit, nor was this possible during the period he spent on the 
lower Columbia.
