Vegetative characteristics
Agave dussiana grows without a trunk with individual rosettes . Your first deep green slightly gray, oblong lance-shaped, upright, bent-over, slightly concave leaves are blue- Glauk and quite shiny. They are pointed suddenly or gradually. The leaf blade is 100 to 175 inches long and 15 inches wide. The leaf margin is straight. There are 2 to 3 millimeters (rarely up to 5 millimeters) long peripheral teeth on it. The slender marginal teeth with a somewhat lenticular base are curved or bent back-pressed in the middle of the leaf blade. The black, conical-awl, strongly bent back end spine is strongly thickened inward at its base and gradually pointed. It is 5 to 7 millimeters long.
Inflorescences and flowers
The "panicle" inflorescence reaches a length of 5 to 9 meters. Its partial inflorescences do not have bulbils . However, these are occasionally formed in the axils of the lower shaft bracts. The flowers are 60 to 65 millimeters long, their tepals are yellow. Their tips are 25 millimeters long. The open flower tube has a length of about 8 millimeters. The elongated spindle-shaped ovary is 30 to 35 millimeters long.
fruit
The narrow to wide elongated fruits are 3 to 4.5 centimeters (rarely from 2 centimeters) long and about 2 centimeters wide. They are stalked and slightly beaked.
