ganter plumosis, simplici ordine digestis, im& basi con- 

 natis, patentibus, tequalibus. 



Puoselia, p. 234. 

 Two new species of this genus have been discovered by 

 Dr. Gillies, of which he has had the kindness to favour me 

 with specimens. The rays of the pappus in these are disposed 

 in a double series. 



Tyeloma, p. 238. 

 The flowers in the specimen of Tylloma timbatum which I had 

 to examine being hardly sufficiently advanced to admit of my 

 ascertaining their structure with perfect accuracy, I beg to sub- 

 join the following amendments of the character and description 

 from an inspection of more complete specimens, for which I am 

 indebted to the liberality of Dr. Gillies. 



Flosculi radii foeminei, bilabiati ; labio interiore brevissimo, erecto, 

 bifido. Pappus capillaris : radiis simplici ordine digestis. 



Flosculi radii numerosi (18—20) bilabiati, foeminei, staminibus 

 sterilibus ; labio exterior e amplo, ligulato, obtuse tridenticu- 

 lato, patulo, 4-nervio, subtus sericeo-villosissimo, nervis 

 lateralibus longe intramarginalibus simplicibus, intermediis 

 superne bifurcatis, ramis apice confluentibus ; interiore lan- 

 ceolato, acuminato, erecto, bifido, brevissimo ; disci her- 

 maphroditi, tubulosi, bilabiati : labiis ereetis, abbreviatis ; 

 exterior e obtuse tridentato ; interiore bilobo. 



Obs.— Hujus flosculi aurei, nee rosei, radio semipollicari. In 

 alterd specie ab amicissimo D. Gillies lecta flosculi albi ; 

 radii 10, foeminei, absque sterilium rudimentis ; labio exte- 

 riore ligulato, acute tridentato ; interiore brevissimo, bipar- 

 tite, laciniis linearibus, acutis, ereetis, inaequalibus. 



Diazeuxis !
