NOTES ON ALABAMA PLANTS 109 
FLOWER: ‘The flowers are regular, pentacyclic and nor- 
mally pentamerous. It sometimes occurs that one or more 
fiowers in an inflorescence deviate from this plan. In certain 
cases each and every cycle of the flower becomes affected and 
the arrangement of such flowers is still according to a uniform 
plan. In other cases only the androecium, or the corolla, or 
both androecium and corolla are affected. With a single ex- 
ception deviation has been found to occur in the direction 
of an increase of members in the affected cycles. Those flow- 
ers which are still arranged according to a uniform plan are 
either hexamerous or heptamerous. One case is known in 
which a single octomerous flower occurred, and likewise a 
single instance is known where deviation from the normal 
occurred in the direction of reduction. In the latter case the 
flower was tetramerous. It has been found that if deviation 
in all cycles occurs only in a single flower, it is always the 
terminal one, and if in more than one, the terminal one rep- 
resents one of them. (Lately two scapes with tetramerous 
flowers have been found; in one instance two flowers, the ter- 
minal one among them; in the other one which was not the 
terminal. Thus the above statement does not hold true in all 
cases, at least not with reference to reduction-deviation. ) 
CALYX: The sepals are distinct and vary considerably in 
length. They are either as long, shorter, or longer than the 
corolla, measuring 7-13 mm. They are oblong or somewhat 
cblong-lanceolate, truncate and one-grooved at the base, ob- 
tuse, acute or acuminate, entire or slightly erose at the apex. 
The inner ones are more or less fornicate. Like the scales 
and bracts, they are of a succulent texture, which character 
is frequently found unchanged in anthesis. Sepals and co- 
rolla-lobes are imbricated in the bud. 
COROLLA: The sympetalous persistent corolla is campan- 
ulate, eylindric-campanulate, or sometimes cylindrical, 5-(re- 
spectively 4-8) lobed, 5-(4-8) saccate at the base, and 7-11 mm. 
long. The lobes are ovate or round-ovate, obtuse or acute, 
one-third to one-fourth the length of the corolla, and spread- 
ing in anthesis.. In texture the corolla is succulent or rather 
waxy, especially the lobes.
