liola obtusa, nervosa. Palcee receptaculi involucro subsimiles. Co- 

 iollula;^fli;<f *. 



The iliird species, Calea piiiifolia, is adopted from Forster's Flo- 

 rulae Insularuni Aiistralium Prodiomus. 



Tiie specimen of this plant in George Forster's Herbarium (now 

 forming part of the extensive collection of Mr. Lambert) is very ' 

 imperfect ; it evidently, however, belongs to the same species with 

 a more complete specimen received, without a name, from Forster 

 by Sir Joseph Banks, in whose Herbarium I have examined it, and 

 ascertained that it has a naked receptacle. It therefore cannot be 

 a species of Calea, which I have no doubt Forster considered it 

 merely iVom a certain degreeof resemblance to h'lsCalea leptophrjllu. 

 From the structure of its stigmata," anthera?, and involucrura, Ga- 

 lea piuij'oliu belongs, indeed, to a very different tribe, and might 

 even be referred to Gnaphalium as it at present stands. But this 

 extensive and ill defined genus evidently requires reformation ; 



* There are two other genera in many respects agreeing with the character here given 

 of Neurolcetia, which it is necessary to point out. The first is Carplu-phnrui of M. Cas- 

 siui (in Bulletin ties Sciences 1816, |). 198), sufficiently distinct in having the stigmata of 

 Eupalorium or Liatris with the habit of the latter, from some species of which it differs 

 only in its receptacle ha\'ing paleas. The second, not yet described, may be named 



PiPTOCARPHA. 



Involucrum imbricatum, turbinatum, scariosum. Receplaculum: pnleh distincti;-. Flosculi 

 tulnilosi, uniformes, limbo revoluto. Anther<s exsertae, basi bisetae. Stigmata filifor- 

 mia, acuta, hispidula. Pappus pilosus. 



Frutex (Brasiliensis) ramosisiimus, deaimle?is ? Folia alterna, integerrima, siiblus incana, 

 Involucra axillarla et terminalia, faiciculata, glabruta, squamis sessitibas olilvsiusculis 

 enerviis, iexlura uniformi. Palese receptaculi squamis intimis involticri sulsimilei, 

 et una cum iisdtm deciducB. Corollulse glalree. Setae antherarum inte^errimce. Pappus 

 alius, radiis simplici serie. 



Obs. I have not seen perfect seeds ; and as even in the unripe state they fall off along with 

 the inner squamse of the involucrum, and the antherse project in a remarkable degree, 

 it is possible the plant here described may be only the male of a dioecious species : it cer- 

 tainly, however, belongs to a genus not before published.
