natural Family of Plants called Composite. 121 
hola obtusa, nervosa. Paleze receptaculi involucro subsimiles. Co- 
rollulæ flave*. 
The third species, Calea pinifolia, is adopted from Forster's Flo- 
rule Insularum Australium 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 degree of resemblance to his Calea leptophylla. 
From the structure of its stigmata, antheræ, 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 Neurolæna, which it is necessary to point out. The first is Carphephorus of M. Cas- 
sini (in Bulletin des Sciences 1816, p. 198), sufficiently distinct in having the stigmata of 
. Eupatorium or Liatris with the habit of the latter, from some species of which it differs 
only in its receptacle having paleæ. The second, not yet described, may be named 
PrPTOCARPHA. 
Involucrum imbricatum, turbinatum, scariosum. Receptaculum: paleis distinctis. Flosculi 
tubulosi, uniformes, limbo revoluto. Anther@ exsertæ, basi bisetæ. Stigmata filifor- 
ə Mia, acuta, hispidula, Pappus pilosus. 
Frutex (Brasiliensis) ramosissimus, decumbens ? Folia alterna, integerrima, subtus incana. 
. Involucra axillaria et terminalia, fasciculata, glabrata, squamis sessilibus obtusiusculis 
enerviis, textura uniformi. Paleæ receptaculi squamis intimis involucri subsimiles, 
et una cum iisdem deciduæ. Corollule glabræ. Sete antherarum integerrime. Pappus 
albus, radiis simplici serie, : 
Ogs. Ihave not seen perfect seeds; and as even in the unripe state they fall off along with 
the inner squamæ of the involucrum, and the anther project in a remarkable degree, 
it is possible the plant here described may be only the male of a dicecious species: it cer- 
tainly, however, belongs to a genus not before published.
