222 SIR JOHN LUBBOCK ON 
The leaf (fig. 33) at the eleventh node is lanceolate, and slightly 
longer than its linear, l-nerved stipules. The third leaf (fig. 34) 
at the twelfth node is shorter and narrower, as are its stipules. 
The fourth leaf (fig. 35) at the thirteenth node is smaller, and 
shows a slight variation in being wider at the middle. The fifth, 
sixth, and seventh leaves, with their stipules, are gradually 
smaller, but otherwise similar. 
The actual number of scales in the buds of the White 
Beam-tree varies a good deal, being fewer in the small buds as 
well as in the large ones containing an inflorescence. The outer 
scales are coriaceous, the inner ones membranous. The bud 
sketched was cut towards the end of April, when the inner scales 
had commenced to push out at the apex. 
The leaves are covered, especially on the underside, with 
white felt. Whatever may be the position of the branchlet they 
stand quite upright, with the undersides outwards (Pl. 13. fig. 5), 
so that they form a succession of intensely white pillars. 
Cerasus lusitanica, Loisel. (Portugal Laurel).—The outer scales 
are a deep crimson, the upper and inner ones rather paler. 
They have three more or less well-marked teeth at the aper. 
There seem to be generally five or six such scales. Then comes 
one with leaf and stipules about twice as long as the base. In 
the next few the stipules are longer than the leaf. 
Potentilla fruticosa, Linn.—The stipules are adnate to the edges 
of the pedestal, then quite free from the petiole, but connate 
along both edges, but to a far greater extent at the edges next 
the petiole, with two triangular free tips. They thus form an 
ocrea, much resembling that of Polygonum (see Tyler, * The 
Nature and Origin of Stipules,’ 1897, p. 44). Two strong nerve 
arise at the base of the petiole, one on exch side, and pass into 
the free tips; they evidently represent the midribs of the t"? 
stipules. They are practically intrapetiolar above the articula- 
tion of the petiole; on the anterior edges they are only connate 
for half or less than half their length. They are so crowded 0D 
the short shoots as to completely cover the axis. 
CAPRIFOLIACER. 
Viburn um Opulus, Linn.—The winter-buds of the G 
Rose, both terminal and lateral (Pl. 13. fig. 1), are oblong-0Y*^ 
varying considerably in size according to their situation on H e 
shoots and the strength of the latter. Each bud is covered with 
uelder
