Three hundred and twenty-first meeting.

August 8, 1849. — QUARTERLY MEETING. The PRESIDENT in the chair.

The Corresponding Secretary read letters of acceptance from Dr. Joseph Leidy, of Philadelphia, and Professor Charles B. Adams, of Amherst College.

Professor Gray gave some account of Argyroxiphium, a remarkable genus of Compositæ, belonging to the mountains of the Sandwich Islands ; of which a second species was obtained by the naturalists of the United States Exploring Expedition under Captain Wilkes. Dr. Gray thinks that “ The genus should be referred to the division Madieæ (a group which belongs entirely to the western side of America, principally to California, and of which the radical leaves of some Californian species exhibit a somewhat similar silky covering); on account of the nearly obsolete pappus of the ray-achenia, and their inclosure in the involute scales of the involucre, and because there is an inner series of scales interposed between the ray-flowers and those of the disk. It has been remarked that, when a genus of two or more species is peculiar to a group of islands, the different islands are apt to have each their own peculiar species. In this instance, while the species on which this characteristic genus was founded belongs to Hawaii, growing on the high mountains of Mouna Loa and Mouna Kea, the second species was found only on the island of Maui, at the base of a high crater; and a plant of an allied, but very distinct, genus was gathered on the island of Kauai. The new Argyroxiphium has much larger capitula than A. Sandwicense, from which it also strikingly differs in the total absence of pappus, just as the Californian Lasthenia (Hologymne) glabrata does from the genuine species of Lasthenia, Burrielia (Baeria) chrysostoma from the other species of that genus, and Ptilomeris calva, Nutt., from its congeners ; adding another to a singular class of cases, all occurring in the same part of the world. The species may therefore be briefly characterized as follows: “A. MACROCEPHALUM : capitulis nutantibus maximis (14 unc. dia

met.); ligulis discum vix æquantibus ; receptaculo conico;

pappo nisi coronula disciformis nullo. “The A. Sandwicense has a convex or depressed-conical, not a flat, receptacle : the pappus is better represented by the figure of Hooker (Icones Plantarum, tab. 75) than by the description of De Candolle.

“The allied genus referred to has much the habit of Argyroxiphium, but in its floral characters is more nearly related to Lasthenia. As it is one of the most striking of the new plants obtained during the cruise, it may be appropriately dedicated to the commander of the expedition ; I have therefore characterized it, in the Botany of the voyage, now in preparation, under the name of

“WILKESIA, Nov. Gen. “Capitulum homogamum, multiflorum. Involucrum campanulatum, gamophyllum, subtri-quadrilobum, lobis apice 3 - 4-dentatis villoso-ciliatis. Receptaculum convexum, nudum. Flores hermaphroditæ, conformes. Corollæ tubulosa, glabræ ; limbo dilatato campanu. lato 5-lobo. Antheræ ecaudatæ. Styli rami cono hispidulo compla. nato apice subulato superati. Achenia elongata, compresso-quadrangulata, ad angulos hirtella. Pappus persistens, e paleis 8-9 lanceo. latis acuminatis rigidis hispido-ciliatis. – Herba grandis crassicaulis ; foliis lineari-lanceolatis nervosis coriaceis, adultis glabratis tomentulosociliatis, caulinis subverticillatis bậsi coadunatis; capitulis in paniculam amplam digestis longe pedunculatis ; floribus ut videtur albidis.
