 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
