Obi. I. Laus ob virtutem suam anthelminticaui apud medicos ame- 

 ricanos et indigenos sumuia. 



Obs. n. Var. (?. (subhirsutum) transitum molitur in Ch. chilense, 

 a quo tamen prima fronte differt inflorescentiae ramis patentissimis et spicis 

 singulis ultra medium omnino aphyllis. — Ch. chilense in Brasilia austro- 

 occidentali facile reperiturum, ac Ch. anthelmintic sane proximum, ha- 

 bitu ab eo recedit longe strictiore, ramulis spicisque valde coarctatis, cau- 

 lis foliorumque indumento copiosiore ac multo longiore; his angustioribus, 

 altius aequabiliusque incisis; spicarum longiorum rhachi villosa ac usque 

 ad extimuin finem dense bracteolata, nee raro bracteolarum fasciculo par- 

 vulo superata; floribus subminoribus hirsutis, perigonii laciniis cariuulatis, 

 demumque odore grato ambrosiaco. 



Obs. HI. Num sequentes Chenopodii species sect. Botryois, in Ame- 

 rica australi repertae, intra Brasiliae Iimites simul occurrant nee ne, hoc 

 tempore non satis constat :
