OF PLANTS CALLED COMPOSITE. 299 



Its real structure was first pointed out by Professor 

 Swartz, who consequently referred it to Galea, with the 

 character of which it exactly agrees. This alteration is 

 adopted in the first edition of Hortus Kewensis, where 

 the generic character of Calea is modified, to admit those 

 species that are without pappus ; and by Geertner, who 

 limits the genus to C. lobata and C. jamaicensis, as the 

 only species that correspond with the Linnean character. 

 But as C. jamaicensis, the original species of Calea, has 

 been shown to have a pappus of a very different kind, it 

 becomes necessary to give a new name to Calea lobata ; 

 and some additions being also wanting to its generic cha- 

 racter, I propose the following, and the name of 



NeUROLtENA, 



Calea Gcert. 



Involucrum imbricatum, foliaceum. Receptaculum palea- 

 ceum, planiusculum. Flosculi tubulosi, uniformes, herma- 

 phrodite Anther ce inclusse, basi muticse (emarginatse), 

 Stigmata acuta, recurva. Pajjpus capillaris, denticulatus, 

 persistens. 



Frutex (American aDquinoctialis) erectus. Folia alterna, 

 inclivisa, et lobata. Corymbus terminalis, comjjositus. In- 

 volucri subovati foliola obtusa, nervosa. Paleae recepta- cisi 

 culi involucro subsimiles. Corollulaejfo;^. 1 



1 There are two other genera in many respects agreeing with the character 

 here given of Neurolama, which it is necessary to point out. The first is Car- 

 phejihorus of M. Cassini (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 paleae. 

 The second, not yet described, may be named 



PirTOCARPHA. 



Involucrum imbricatium, turbinatum, scariosum. Receptaculum : paleis di- 

 tinctis. Flosculi tubulosi, uniformes, limbo revoluto. Anthem exserta>, basi 

 bisetse. Stigmata filiformia, acuta, hispidula. Pappus pilosus. 



Frutex (Brasiliensis) ramosissimus, decumbens ? Folia alterna, integerrima, 

 sublux incana. Involucra axillaria et terminalia, fasciculata, glabrata, squamis 

 sessilibus obtusiusculis enerviis, textura uniformi. Palese receptaculi squamis
