A specimen described by Solms-Laubach as a Kalymma petiole occurs in organic connexion with a stem of Calamopitys (fig. 454^ C: a detached petiole is shown in fig. 454, D).

A fuller account of Kalymmor (fig. 456) is given on a later page, as the petioles so named belong; to more than one species of Fig. 455. Calamopitys Saturni. A, stem with leaf-bases; x 5. B, stele- showing leaf-trace after emerging from the secondary xylem; x 16. (After In Calamopitys Saturni we have a plant agreeing with Lygino- pteris in the possession of secondary xylem of the manoxylic type and in the structure of the common primary bundles, while it is distinguished from Lyginopteris by the greater number and by the structure of the bundles in the axis of the leaf. â /cdXu/tjua, a veil or covering. â White (052) B p 384_.
