is divided into two regions: a massive leaf base with two large stipules, and an imparipinnate compound lamina with 5-6 articulate leaflet pairs; the vestigial leaflets of the cataphylls
remain appressed to the thick rachis and the terminal leaflet folds (Fig.

For example, seedlings with single cataphylls
can be associated with entire eophylls, and seedlings with more than one cataphyll
generally have bifid, palmate, or pinnate eophylls.

There are large, quadrate, rhombic leaf bases with an inverted omega arrangement of vascular bundles and smaller, narrowly, transversely, rhombic cataphyll
Except for Stangeria eriopus, the stem apices of all cycad species bear short, triangular, woody, often tomentose, modified leaves with a pointed free end, known as cataphylls

The presence of two stem axes was also observed in Smilax polyantha, but the underground stem axis originated from axillary buds of the cataphylls

With reference to the seedlings morphology of Clusiaceae species, which have been already investigated, some differences considered relevant are recorded, as phanerocotylar seedling, epigeal and foliaceous cotyledons in Vismia guianensis (MOURAO; BELTRATI, 2001); undeveloped cotyledons in Garcinia parvifora (HZN, 1972); and cataphylls
