170 PHANEROGAMIA. 



prickles. They pass into the first variety, in which the fruit is armed 

 with rather longer prickles; the leaves white-tomentose underneath, 

 glabrate above, only Z-h-nerved at the base, which is either acutish or 

 rounded, not cordate, rhombic-ovate, varying to oblong or ovate-lanceo- 

 late, not lobed, the larger ones doubly toothed. This might be the U. 

 viminea of Cavanilles; but the involucel is no longer than the calyx, 

 and its segments are obtuse. — The second variety has rather larger 

 flowers and fruit, the latter densely armed with larger prickles ; the 

 leaves are large (3 or 4 inches in diameter) and rounded, subcordate, 

 7-9-nerved, flabellately 3-5-lobed; the lobes short, coarsely and spar- 

 ingly toothed, and finely serrulate ; the upper surface roughwh with 

 a short stellate pubescence, the lower canescently tomentose, and hirsute 

 on the ribs and veins; the petioles, branchlets, &c, also hirsute with 

 spreading hairs. The calyx and involucel are hispid or strongly hir- 

 sute, and the segments of the latter are narrowly linear, acute, and 

 longer than the calyx.

This must, I think, belong to DeCandolle's Urena morifolia, which 

 came from the Friendly Islands, although the leaves when young are 

 rather strigose-hirsute than tomentose, and when full grown are spar- 

 ingly hirsute and scarcely paler underneath. It resembles U. sinuata; 

 but the leaves are larger, from 3 to 5 or more inches in length, very 

 deeply 3-5-lobed; the lobes, at least the three larger ones, obtusely 

 three-lobed and sinuate above, contracted below into an elongated and 

 linear base, which is sharply serrate, as are likewise the very wide 

 sinuses. The uppermost leaves, in the single specimen, are linear- 

 elongated, something as those of U. reticulata are represented by 

 Cavanilles, and either undivided, or barely sinuate-toothed, or ob- 

 scurely 1-3-lobed. Involucel hirsute; the segments as long as the 

 calyx.
