General Biology Additional Information | Chorda filum is a summer annual, falling into decay in the autumn and disappearing during winter. Growth rate is maximal during the summer. The adult frond is a hollow tube, the walls of which are spirally constructed. The frond is frequently inflated with gases in the terminal region. Plants usually grow in clumps. The end of the frond decays continuously and is replaced by growth from a sub-terminal meristem. Hairs are sparse or absent on older plants. | ||
