360, partim. H. polychstum (sp. nov.): annum, glabrum; caule diffuse ramoso ; 

 foliis pinnatipartitis, lobis 9-13 filiformibus muticis grosse glandulosis; peduncu- 

 lis subcorymbosis brevibus parce setaceo-bracteatis ; involucro turbinate ebracteato ; 

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



pappo e paleis brevibus obovatis 10- 16, quarum 5-8 obcordato-bifidis arista setiformi e sinu exserente 

 corollam disci ajquante 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 diameter, very many-flowered ; the rays ten or twelve, obovate, nearly three lines long. The 

 paleffi of the pappus are broader in proportion and the lobes of the aristate ones more rounded than in any 

 other species. 



5. H. Nejei (DC. I. c.) : glabrum ; caulibus difli"usis apice ramosis ; pedunculis brevibus parce bracte- 

 atis ; foliis pinnatipartitis, lobis filiformibus ; involucro campanulato ebracteato ; pappo e paleis 10 oblon- 

 gis bifidis cum arista setiformi corollam adcequante e sinu exserente, lobis acutis muticis. — I have taken 

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

 mixed with the following, which accords with De Candolle's character (e,xcept that there are sometimes 

 one or two small 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 Mexico, not from Chili. 



7. H. DiFFUSUM (sp. nov.) : glabrum ; caulibus diffusis vel decumbentibus ; foliis pinnatipartitis, lobis 

 filiformibus ; pedunculis subcorymbosis minutim parceque bracteatis ; involucro hemisphasrico seu turbina- 

 te ebracteato ; pappo e paleis anguste oblongis 10 apice breviter bisetosis et longe uniaristatis, atque 5-7 

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

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

 in diameter), a little larger than in the following species. Awns about the length of the disk-corolla.
