Florida Flowers and Insects 313 
RUBIACEAE. 
GeLsEMiIum Sempervirens, Ma., Y. — The corolla 
is 30 to 35 mm. long, its five-lobbed border ex- 
panding to the same extent. The base is 25 mm. long. 
From a narrow part below, which is 8 mm. long by 2 mm. 
wide, it widens regularly to a throat which is 15 mm. 
wide. The throat within is rich orange. 
In the short-styled form the 4 lobed stigma rises 10 
mm. The 5 filaments are attached to the corolla for 8 
mm., their free ends exposing the anthers 6 mm. beyond 
the mouth of the tube. The stamens form a central col- 
umn, the anthers being extrorse. The bee touches the 
stamens exteriorly and inserts its tongue between the 
filaments. The stigma lobes project between the fila- 
ments. The tube is narrowed by the filaments, the pistil 
and the stigma. A tongue at least 10 mm. long is neces- 
sary to drain the nectar. There is a tendency to sterno- 
tribe zygomorphism. The flower is horizontal, the bor- 
der vertical, the upper lobes somewhat reflexed. The 
stamens are bent a little upward, and Emphoropsis lands 
upon them and enters on the upper side of the flower. 
In the long-styled form the stigma is less exserted than 
the anthers in the short-styled form and the stamens are 
longer than the pistil of that form. The tube is ob- 
structed by the anthers. The style is declined toward 
the lower side. 
Self-pollination might be effected by insects in the 
short-styled form. In the other form it can hardly occur.
