222 SIR JOHN LUBBOCK ON STIPULES, 
terete, channelled above, dilated to a broad stout base, which 
shelters the young bud, slightly connate for about 3 millim. at 
the very base. 
Cistus laurifolius has its petioles connate and sheathing at the 
base. The leaves are ovate or lanceolate, acuminate, 3-nerved, 
leathery, glabrous above, tomentose beneath, petiolate. Petiole 
semiterete, flat above, sheathing and connate at the base, forming 
a cup about 3 millim. deep, hairy and covered with an adhesive 
gum, as is the stem. 
C. ladaniferus var. angustifolius differs from the Tes in NE 
its leaves lanceolate-oblong, obtuse, sessile, tapering to a broad 
amplexicaul base, connate for 1 millim., enclosing the bud in the 
young state, and forming a cup round the axis afterwards. 
C. longifolius has its leaves lanceolate, undulate, rugose, nar- 
rowed to a short, winged, petiole-like base, dilated at the base 
and connate for 4-4 millim., completely enclosing the bud in the 
young state. 
The leaves of C. monspeliensis are small, oblong-lanceolate, 
obtuse, 3-nerved, revolute at the margin, sessile, amplexicaul, 
thinly hairy, but almost woolly at the edges, but more especially 
close to the base, connate for I i-i millim., and completely en- 
closing the bud. 
In C. platysepalus the leaves are oblong, obtuse, 2-3 inches 
long, 3-nerved at the base, slightly narrowed there, sessile, con- 
nate for 4-3 millim., erect when young and completely enclosing 
the bud. 
The leaves of C. cyprius (fig. 3) are lanceolate, acuminate,
