BUDS AND STIPULES. 263 
The terminal or axial bud is enclosed by the sheath of the 
youngest leaf, and the rest are imbricate. 
The undivided lamina, the grooved petiole, and the large sheath 
of this species are all very different from those of Tacca arto- 
carpifolia. 
RoxBURGHIACES. 
Stemona viridiflora, Benth. & Hook. f.—The terminal bud is 
subulate, elongate, or slenderly conical, covered in succession 
by each pair of leaves, which are incurved at the sides so as 
to cover the bud with very short petioles, or sessile in their 
earlier stages. The thickened and dilated base of the petiole 
is accommodated in the space left uncovered between the 
petioles of the next older pair of leaves while still in bud. The 
leaves remain erect and incurved at the sides for some time after 
they fold away from the bud. 
Axillary buds are mostly flower-buds, and are sheltered by the 
dilated base of the petioles in their early stages. 
The stems are annual, and produced from a subterranean, 
fusiform, tuberous rootstock or rhizome. 
LILIACEE. 
,Dianella aspera, Reg.—Sheaths laterally compressed, equitant, 
dilated and amplexicaul at the base, closely aggregate and im- 
bricate ; the edges are pale and membranous, while the midrib 
8 developed into a narrow wing, finely serrulate and prolonged 
on to the base only of the lamina. 
The terminal bud is deeply sunk amongst the equitant sheaths. 
Axillary buds arise in the axils of the primary leaves at the base 
of the shoots. These leaves are very short and conduplicate, but 
not differentiated into sheath and lamina. The shorter ones are 
triangular, the longer more subulate, and all those that are 
undifferentiated into sheath and lamina become brown and die at 
an early age.
