The axis was elongated and terminated above, in one case, by a similar abortive flower; in another, by an umbel of such flowers, every part of which was more or less carpellary; while all the bracts on the prolonged axis, even those out of the axils of which the branches of the umbel sprang, were similarly made of open carpels.
