essential characters of Dunalia. The genus Dunalia, founded 
by Prof. Kunth on a shrubby plant with much the habit of a 
Witheringia, brought from the Cordillera of New Granada 
by Humboldt, was placed by that learned botanist among 
Cestrinee, on account of the resemblance of its flowers to 
those of Cestrum, although he confesses he knew nothing of 
the form of the embryo of its seed. Until this fact be ascer- 
tained it remains doubtful whether it may not with equal 
reason be classed in Solanee, near Salpichroa or Chenesthes, 
which view is much favoured by its numerous ovules seen 
upon the thickened placenta on the dissepiment ; but on the 
other hand it must not be forgotten that some analogy exists 
between the appendiculate processes of the filaments in this 
genus, and the singular projection often seen upon the fila- 
This is said to be a shrub 6 feet high, with many spreading, thick, leaf- 
less branches ; branchlets an inch long, furnished with leaves at base, spi- 
nose at the apex ; leaves fasciculate (4-7), petiolate, 4-6 lin. long (includ- 
ing the petiole 1 lin.) 2-24 lin. broad; flowers subaxillary, peduncles 3-4 
lin. long, filiform, and smooth; calyx semiglobose, obsoletely 5-toothed, 
nearly entire, smooth, with 5 small acute teeth, about 1 line long ; corolla 
smooth, tubular, somewhat curved, 7 lines long, border with 5 equal, acute, 
spreading lobes with ciliate pubescent margins ; stamens inserted at base 
of tube, and equal in length to the corolla, filaments smooth, anthers erect, 
oblong; ovarium conical, smooth; style filiform, smooth, rather longer 
than the stamens ; stigma thickened, green.

A handsome shrub, said much to resemble the last mentioned species 
but differing in its smaller lanceolate leaves ; branchlets covered with thick 
white tomentum, 1-14 in. long, often spiny at the apex, bearing fascicles 
of leaves at the base; peduncles axillary, smooth, 6 lines long; caly* 
smooth, 3 lines long, with 5 short equal obtuse teeth, terminated by 4 
woolly cuspidate point; corolla tubular, 15 lines long, with a slightly 
spreading border, having 5 short triangular acute lobes with ciliate mar- 
gins; berry red, twice the size of a pea, globose, partly enclosed within 
the calyx, which now becomes unequally 3-4 cleft. s
