THEIR FORMS AND FUNCTIONS. 511 
petioles, which retain an erect or ascending direction for some 
time. 
The rim connecting the bases of the petioles sometimes develops 
a foliaceous auricle like that of B. auriculata, and frequently a 
lanceolate foliaceous process is developed on one side of the stem, 
instead of the auricle, and on different sides of the stem at different 
nodes. Neither of these processes is much developed in bud, 
and they do not appear to form any effective protection. 
In Buddleia globosa, Hope, the leaves are opposite, decussate, 
lanceolate, acuminate, densely felted beneath with a fine silvery 
tomentum. They are all but sessile and the base is slightly 
dilated, semiamplexicaul, and connected by a rounded transverse 
ridge. There is no interpetiolar and stipular outgrowth as in 
B. auriculata and B. Colvilei. 
The terminal bud is tetraquetrous and greatly elongated before 
the leaves expand. Two of them completely cover it, and their 
edges lie flat upon one another, but the centre of each leaf is 
deeply channelled so as to accommodate the younger members. 
Axillary buds are frequently present, and they are sheltered in 
their earlier stages by the erect base of the leaves before they 
become fully expanded, and also by their own tomentum. 
In Fagrea zeylanica, Thunb., the leaves are opposite, decussate, 
very unequal, petiolate, exstipulate, obovate, gradually narrowed 
into the petiole, glabrous, entire, softly leathery or semi-fleshy. 
The petioles are short, very stout, compressed laterally, furrowed 
at the base only on the upper side, considerably dilated at the 
base and auricled; the auricles are erect and clasp the stem in 
front of the petiole ; they are not connate. 
The terminal bud in the resting stage is included between and 
beneath the auricles. When it commences to grow, the very 
unequal pair of leaves are closely adpressed face to face and 
emerge thus more easily from the encasement formed by the 
dilated and auricled petioles. 
The axillary buds are completely covered or enclosed in the 
same way. Except for the slit sheath or case, this agrees with 
Clusia and also entirely with the species of Anthocleista. Conf. 
also Citharexylum. 
The stipules in Fagrea spp. are well shown in Blume, 
‘Rumphia,’ ii. plates 72-81 ; they are largest in F. awriculata, 
Jack, and described on p. 26 as follows :—“ The extreme base of 
the petiole is enlarged like a short ligule, triangular in shape,
