The third species, Calea pinifolia , is adopted from Forster’s Flo- 
rulae Insularum Australian! Prodromus. 
The 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 from a certain degreeof resemblance to hisCa/ea leptophylla . 
From the structure of its stigmata, anthers, and involucrum, Ca- 
lea pinifolia 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 Neurolcsna, which it is necessary to point out. The first is Carphephnrus of M. Cas¬ 
sini (in Bulletin des Sciences 1816, p. 198), sufficiently distinct in having the stigmata of 
Eupalorium or Lialris with the habit of the latter, from some species of which it differs 
only in its receptacle having paleae. The second, not yet described, may be named 
PiPTOCARPHA. 
Involucrum imbricatum, turbinatum, scariosum. Receplaatlum: pnleis distinctis. Flosculi 
tubulosi, uirformes, limbo revoluto. Antherce exsertae, basi bisetae. Sligmuta filifor- 
raia, acuta, hispidula. Pappus pilosus. 
Frutex (Brasiliensis) ramosissimus,decumbens ? Folia allerna, integerrima, sultus incana. 
Involucra axillaria et terminalia, fasciculata , glabruta, squamis sessilibus oblusiusculis 
enerviis, textura uniformi. Paleae receptaculi squamis inlimis involucri subsimiles , 
el un'a cum iisdtm deciduce. Corollulae glabrce. Setae antherarum inlegerrimce. Pappus 
albus , radiis simplici serie. 
Ons. I have not seen perfect seeds ; and as even in the unripe state they fall off along with 
the inner stjuamae of the involucrum, and the antherae 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.
