Flowering shoot ovoid, covered with linear bracts some of which are prolonged above the conical apex as slender tapered organs and two of them bear a few short lateral. Fig. 561. Williamsonia scotica. Strobilus in surf ace-view; I, bract with short lateral appendages. (Royal Scottish Museum, Edinburgh; f nat. size.) appendages (fig. 561, I), probably reduced leaflets, near their distal ends. The cyhndrical axis, completely hidden by bracts, 1-5 cm. in its widest part, bears in the lower or sterile region bracts and long hairs and in the upper part interseminal scales and immature megasporophylls which together form a narrow band (fig. 562, S) 2 mm. broad extending over the incompletely preserved and conical apex, as in some of the American examples.
