Mon′o‐sep″al‐ous (?), a. [[Mono- + sepal: cf. F. monosépale.]] (Bot.) Having only one sepal, or the calyx in one piece or composed of the sepals united into one piece; gamosepalous. ☞ The most recent writers restrict this term to flowers having a solarity sepal, and use gamosepalous for a calyx formed by several sepals combined into one piece.
