Gremia aromatica; annua, ramosa, glutinosa, foliis lanceolatis semi- 
amplexicaulibus undulato-dentatis inferioribus pinnatifidis. 
Root small, annual. Whole plant sprinkled with excessively minute, glan- 
dular, yellow dots, which give out a powerful odour, and render it glu- 
tinous to the touch, particularly when pressed. Stem about a foot high 
in the largest specimens, slender, much branched, branches nearly erect, 
striated, glabrous. Leaves scattered, 2-3 inches long, below pinnatifid, 
with remote segments ; above lanceolate, toothed and waved, at the base 
semiamplexicaul. 
Flowers solitary, terminal, exactly spherical, and about the size of the fruit 
of the Wood Strawberry. JInvolucre of 8 or 10 linear leaflets, glandular 
on the outside, spreading and lax, soon reflexed. Florets, all of them 
tubular and perfect, much crowded. Corollules ovate, inflated, yellow, 
clothed with viscid, glandular hairs ; the mouth has 5 connivent teeth. 
Stamens 5, bidentate at the base of the anthers, included. Style filiform, 
as long as the corollule. Stigma bipartite, the segments spreading over 
the mouth of the corollule, plane alate glandular at the extremity. 
Fruit or Achenium oblong, hairy, especially at the angles, which are pro- 
minent, crowned at the summit with from 5-7 large, pure white, deli- 
cately fimbriated, membranaceous, aristate scales. Receptacles ovate, 
tuberculated, chaffy ; the scales small, linear, deciduous. 
Seeds of this interesting plant were kindly communicated 
to me, along with many others, in the spring of 1824, by Mrs 
Maria Granam, on her return from Chili, where they were 
gathered during some of the excursions made by that Lady in 
Various provinces; perhaps at Quintero, just as she was on the 
point of quitting the country, where, as she says in her amusing 
and instructive account of her sojourn, “ we gathered many 
seeds and roots, which I hope to see springing up in sins
