472 SIR JOHN LUBBOCK ON STIPULES, 
tolerably large, and more persistent than the leaves to which 
they belong, bifid at the apex, erect, and inserted on the pedestal 
on a level with the insertion of the leaf. The buds are thus 
protected by the erect stipules on two sides, and by the stem 
and petiole on the other two. The terminal buds consist of 
numerous leaves folded into a small space along the course of 
the principal veins, and of numerous stipules which equal the: 
leaves in length; both leaves and stipules are very hairy, so 
that altogether the protection afforded is considerable. 
Towards the apex of the stem the leaves become very much 
reduced in size, and finally disappear long before the stem has 
ceased to grow or produce flower-buds. The stipules remain. 
and are connate into a 5-6-fid semiamplexicaul piece, supporting 
and protecting the flower-buds in their earlier stages. The 
latter are intensely downy. 
In Althea rosea, Cav., the stipules are similar to those of 
A. Heldreichii. In A. officinalis, Linn., they are linear or subulate,. 
entire, acuminate, or bifid, with unequal segments, and caducous. 
In Abutilon megapotamicum, St.-Hil. & Naud., the stipules are: 
ovate, acute, concave on the back when fully developed, unequal 
at the base, the side away from the petiole being the larger, and 
that next the petiole cut away ; they are unequal in size, that 
on the upper side of the drooping branches being the broader: 
and often the longer. They appear to be about as persistent as- 
the leaves, and amply protect the terminal buds. 
In Sidalcea candida, A. Gray, the large ovate green stipules. 
cover the young leaves or inflorescence. 
In Callirhoé involuerata, A. Gray (fig. 8), the leaves are 
3-7-lobed or parted, with long or short’ petioles grooved on the 
upper side, slightly dilated at the base. The stipules are 
foliaceous, obliquely ovate, the lower ones generally entire with 
an auricle on the side next the axis, inserted with a broad 
base upon the stem and clasping the latter with its auricles, 
while the other edge overlaps and entirely covers its own 
petiole, although not adnate to it. Towards the apex of the 
flowering stem the leaves become smaller and finally disappear 
altogether. The stipules are, however, developed, and are 
connate throughout their length into one keeled piece erosely 
toothed along the apex. The internodes are very slightly 
developed here, so that the upper flowers appear crowded 
together in oneinvolucrated raceme. Both terminal and axillary:
