 acters of TTymenatherum, have the aspect of Dysodia.

360, partim. H. roLTcna:TUM (sp. nov.) : annum, glahrum ; caule difFuse ramoso ; 

 follis pinnatipartitis, lobis 9- 13 filiformihus muticis grosse glandulosis; peduncu- 

 lis subcorymbosis brevibus parce setacco-bracteatis ; involucro turbinato ebracteato ; 

 pappo coroUa disci paullo breviore e paleis 18-20 linearibus subconformibus bi-

 corollam disci ccquante lobis obtusis muticis, alternis paullo minoribus obtusissimis integerrimis. — Mexico, 

 Mr. Bales. — This I possess from Sir William Hooker's duplicates. It much resembles the next, but is a 

 coarser plant, with larger heads, and still more of the aspect of a Dysodia. The heads are a quarter of 

 an inch in dlamcter, very many-flowered ; the rays ten or twelve, obovate, nearly three lines long. The 



palerc of the pappus are broader in proportion and the lobes^of the arisfate ones more rounded than in any 

 other species. 



5. II. Nexi {DC. l. c.) : glabrum ; caulibus diffusis apice ramosis ; pedunculis brevlbus parce bracte- 

 atis; foliis pinnatipartitis, ?obis fiiiformibus ; involucro campanulato ebracteato ; pappo e paleis 10 oblon-. 

 gis bifidis cum arista setiformi corollam adajquanle e slnu exserente, lobls acutis mutlcis. — I have taken 

 Ihe character of the pappus, &c. from a fragment of a Mexican specimen (collected by Mr. Tate), inter- 

 mixed with ihe following, which accords with De Candolle^s character (except that there are sometlmes 

 one or two smal! additional palese, which are awnless and entire). My notes upon his specimen are not 

 sufficient absolutely to identify it with this species. But I have little doubt that the plant of Nee came 

 from Mcxlco, not from Chili. ' 



7. II. DiFFtJsuM (sp. nov.) : glabrum ; caulibus difFusis vel decumbentlbus ; follis pinnatipartitis, lobis 

 filiformibus; pedunculis subcorymbosis minutim parceque bracteatls ; involucro hemisphferico seu turbina- 

 to ebracteato; pappo c paleis anguste oblongis 10 apice breviter bisetosis et longe uniarlstatis, atque 5-7 

 multo minoribus subulatis vel subulato-aristulatis integerrimis. — Mexico, Mr. Tate (in herb. Hook.). 

 Plant with the aspect, foliage, &zc. of the preceding ; the heads about the same size (two and a half lines 

 m diameter), a httle larger than in the following species. Awns about the length of the dlsk-corolla.
