same length. Leaf —2, had a sheath of 0.7 cm, a blade of 53 cm. All lea- 
ves inside of these had a sheath of measurable size; the one of leaf —7 
had a length 0.3 cm and enclosed a very young panicle, 0.25 cM long. 
The panicle is consequently, already during its first stages of develop- 
ment, protected by a leafsheath of measurable length. The first stages 
of development of a panicle therefore can be present already within the 
top of a cane-stem, even if this stem shows no external signs of flowe- 
ring, because all floral leaves are still enclosed, in a not adult condition 
within the case of leafsheaths. 
Fig. 5. pictures a „boenting”’ stemtop of Bandjermassin hitam. The 
sheaths of leaves 8—4 have about equal length. From leaf 3 tot leaf 1 
the length of the sheaths increases gradually, the distances between the 
successive leafjoints is here greater than in the case of the lower leaf- 
sheaths, notwithstanding thestill extreme shortness of these. Thesheath
