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 my own 
NOL s TEL. | |
