Not illustrated. 1840 edition. Excerpt: ...attached to them. Fig. 3 represents one of the finest of these, but is not quite in a state of maturity. When the capsule is fully matured, a transverse section at about midway between the base and apex forms nearly an equilateral triangle, the sides of which very slightly incline towards the axis of the fruit. Near the base of the capsule the middle of each of the sides is slightly gibbous. In the greater number of my specimens the epicarp is wanting; but in the fruit represented by fig. 4, and in several other well-preserved specimens, it exhibits an uneven corrugated appearance, as shown on the surface at a, fig. 4. The seed, when viewed sideways, presents a semi-cordate outline; at the apex it is very much compressed laterally, but towards the base it swells out suddenly and very considerably, so as to assume nearly the same form as that of the common edible mussel, --lIytilus edulis. The receptacle (d, fig. 3) is well preserved; and the remaining portion of the peduncle (a), when viewed with a power of eighty linear, exhibits the bark in a fine state of preservation: it is smooth, but somewhat wrinkled longitudinally. I have not been able to obtain a satisfactory view of the woody structure of the stalks, but from their general appearance should suppose it probable that these fruits have been the produce of trees or shrubs. CUPANOIDES sonaneumros. (Plate 11, figs. 7, 8, and 9). Capsule three-sided, angles obtuse: base nearly equal to the apex in breadth. Epicarp transversely corrugated. Seeds reniform, slightly compressed laterally at the base.
