which easily peels off, and is rough to the touch, and, on 
the young branches, rough with hairs. Leaves opposite, 
ovate, shortly petiolate, deeply and very irregularly ser- 
rated, often angled, rough on both sides with harsh, rigid 
hairs. Flowers solitary, large, terminal upon the branches, 
or axillary in the dichotomies. Calyx with its tube ad- 
herent with the germen, rough with hairs, the five seg- 
ments lanceolate, reflexed. Petals five, broadly ovate, 
acuminulate, deep, rather fulvous yellow, patent. Stfa- 
mens numerous, the ten outer ones the largest. Filaments 
slender, yellow. <Anthers rounded. Germen roundish, ob- 
long, inferior. Style filiform. Stigma obtuse. Immature 
capsule oblong, crowned with the style and the reflexed 
segments of the calyx, very rough ; according to Cava- 
NILLEs about six-seeded. 
Seeds of this plant were sent to the Glasgow Botanic 
Garden from Yazo, in the valley of Canta, Peru, by Mr. 
Crucksnanks, and the plant produced flowers in April, 1832. 
When noticing this species, from the dried specimens com- 
municated to me by the same traveller, in the Botanical Mis- 
cellany above quoted, I was led to refer it to the MenTzELIA 
aspera of Linnzus, and I am now far from certain that 
authors have done right in separating the two, the differ- 
ences appearing to me to rest on very slight grounds. I 
there likewise mentioned, that the M. oligosperma of North 
America, seemed to me to be scarcely different from the 
present. Its flowers are smaller, more tawny, and the seeds 
are described as two or three in each capsule. 
CAVANILLES and Dr Canpo.te give our plant as an in- 
habitant of Mexico, where it is called Sazale. Its pow- 
dered roots are violently purgative and used medicinally.
