1. Quinchamalium linifolium, FeuilU {non Meyer), sub 

 Q. lini folio," Hist. pi. medicinales, p. 57, tab. 44, et in Observ. 

 Append, (vol. iii.) tab. 44. — Quinchamalium chilense, in parte 

 {non Molina), Lam. Diet. vi. p. 34. In Chile, primo ab auct. 

 lectum in prov. Concepcion (lat. 37° 40' S.) : v. s. in herb, meo 

 (19556), pi. lecta in prov. Contigua, Talca {Germain). 



The plant of Germain quite corresponds with the description 

 and drawing of Feuille. It has a similar branching root 2 in. 

 long, throwing out about 9 suberect simple or branching stems 

 3-4 in. high, as in Feuille's drawing ; leaves linear, narrow, 

 mucronulate, patently divergent and curving, 2-3 lines apart, 

 4-8 lines long, \ line broad, glabrous ; inflorescence terminal in 

 a capitate head, about ^ inch broad, upon a peduncle bare at its 

 base for a length of 4 lines ; calycles closely approximated upon 

 the 4 faces of the peduncle, depressed, concave, with lacerated 

 margins ; calyx globular, with 5 unequal small teeth ; corolla 

 yellow, glabrous ; tube slender, cylindrical, of a greenish hue, 

 4^ lines long ; segments acute, subreflexed, yellow outside, reddish 

 within, 2 lines long, i line broad. 



2. Quinchamalium chilense, Molina, Saggio (1782), edit. 

 Brit. (1809) i. p. 123 {non A. DO.) ; Lam. Diet. vi. 34, in parte 

 (1804) ; Willd. Syst. ii. 1217 (1799) ; Hook. Voy. Beechey, p. 44, 

 in parte (1841). In Chile centrali : v. v. et sicco in herb, meo 

 (no. 227), Concon, prov. Valparaiso. 



I found this plant in 1820, its vernacular name being Quincha- 

 mali. It is annual, with a stoutish, fistulose, herbaceous stem, 

 about 5 in. high (sometimes, according to Molina, 9 in. in height), 

 bare at its base for 1 inch, thence throwing up about G suberect 

 alternate branches, again branched, all rising to the same level ; 

 leaves 4 lines apart, patently diverging and curving upwards, 

 linear-lanceolate, acute at both ends, with subrevolute margins, 

 glabrous, 1-nerved, with many transverse veins, 6-7 lines long, 

 £ line broad, on a short slender petiole ; inflorescence terminal, 

 with numerous sessile flowers aggregated in a subglobular head 

 f inch in diameter ; calycles cupuliform, with a lacerated margin, 

 persistent, crowded upon the 4 faces of the acutangular peduncle ; 

 calyx globular, often caducous, 1 line in diameter, 4-costate, each 

 nerve terminating in a short acute tooth, the outer one a little 

 longer; tube of corolla slender, 3 lines long, shortly adnate at its 

 base to the ovary ; segments 5, acutely triangular, 2\ lines long,
