1905] HOLM—MUNROA SQUARROSA 129 
In jig. ro there are represented four inflorescences and five vege- 
tative shoots, but much more equally distributed than before, since 
the main culm bears here a larger number of leaves—four instead 
of two—three of which (L'-L3) subtend shoots. These leaves 
(Z'-L4) are also exactly alternate and lie in one plane, and 
the uppermost (Z4) precedes an inflorescence (S*) which termi- 
nates the main culm. Similar to the specimen illustrated in 
jig. 9, the first leaf (Z") subtends a shoot with a large prophyllon 
(P*), and this shoot is also turned go° to the side of the supporting 
leaf and the prophyllon; but it bears only two leaves (L‘ and L°), 
one of which (Z5) has an axillary shoot consisting of a prophyllon 
and a vegetative apex. The other leaf (Z°) has no shoot and precedes 
the terminal inflorescence (S?) of three spikelets, arranged in con- 
formity with the leaves (L5 and L°). Another shoot is observable 
in the axil of the large prophyllon P', which shows the same develop- 
ment as the one in jig. 9, but with the exception that an axillary shoot 
is visible within the prophyllon (P); thus two prophylla of the shoot- 
complex pertaining to leaf Lt support buds. 
Examining the other shoots, we find one in the axil of leaf LZ? with 
a prophyllon (P?), whose leaves and inflorescence are likewise turned 
go° to the side, with exception of the prophyllon. This shoot con- 
sists of a terminal portion with two leaves and a two-flowered inflor- 
escence (S3; one median and one lateral spikelet), besides a sec- 
ondary, purely vegetative bud which is developed in the axil of the 
prophyllon, but although axillary its prophyllon has become sup- 
pressed. The position of the floral shoot, however, shows clearly 
that it is terminal, and that the other much smaller one must belong 
to the prophyllon. A similar construction of two shoots pertaining 
to one system is to be found in the axil of the leaf L3, where we observe 
the same position of the prophyllon (P3) and of the green leaves as 
before. The shoot bears two leaves and is terminated by a single 
spikelet (S+), which shows the arrangement of the glumes as that of 
a median rather than of a lateral spikelet, since the glumes alternate 
with the leaves. It is now interesting to see that the prophyllon (P) 
here also subtends a bud, and a purely vegetative one. The fourth 
leaf (L+) has no bud and precedes directly the inflorescence (S‘), 
which terminates the main culm; thus the median spikelet represents
