DUBAUTIA, Gaud. — The best published description is that of Lessing, who rightly ascribed to D. plantaginea a couple of paleæ on the receptacle. These, overlooked by Hooker and Arnott, and therefore, it would seem, ignored by De Candolle and Endlicher, are generally if not always present whenever the flowers are more numerous than the scales of the involucre, subtending the flowers which are not subtended, and their achenia embraced, by the involucral scales. In D. laxa, accordingly, these paleæ are more obvious, and still more striking are they in a new species with many-flowered heads, which is moreover remarkable for its truly paleaceous, instead of aristiform, pappus. As the old species need diagnoses as well as the new, I append the characters of all of them.

1. DUBAUTIA PLANTAGINEA (Gaud.): foliis glabratis glabrisve elongato-lanceolatis sensim acuminatis basi modice angustatis; capitulis parvis 7-10-floris numerosissimis in ramos divergentes folioso-bracte

atos panicula thyrsoideæ magnæ congestis; receptaculi parvi paleis 1-3; corollæ tubo gracili limbo abrupte campanulato duplo longiore pappi sordidi paleas aristiformes barbellatas subsuperante. - Oahu and Hawaii. In Gaudichaud's original specimens the inflorescence is undeveloped, so that his plate gives no idea of the ample, thyrsoid, compound panicle, the divaricate primary branches of which are sometimes six inches long, nor of the great number of the small heads. The leaves, also, are represented as much too broad at the base.

2. DUBAUTIA LÆVIGATA (sp. nov.): foliis oblongo-lanceolatis deorsum longe attenuatis quasi petiolatis ultra medium argute serratis laxe inconspicue plurinerviis nitidis ramisque glaberrimis; panicula thyrsiformi pedunculata nuda; receptaculo parvo. Flores desunt.— Kauai, Sandwich Islands. Incompletely known; possibly a variety of the foregoing.

3. DUBAUTIA LAXA (Hook. & Arn.): foliis glabratis vel strigosohispidis oblongo-lanceolatis rariusve ovali- seu cuneato-oblongis antice argute serrulatis acuminatis deorsum longe attenuatis; capitulis 10-15floris parvulis in cymam brevem congestis; corolla paleas pappi (mox rufi) subulato-aristiformes serrato-fimbriolatas vix superante, tubo glanduloso. - Oahu. Badly named, the inflorescence being less lax than that of D. plantaginea in fully developed specimens.

4. DUBAUTIA PALEATA (sp. nov.): foliis strigoso-hispidulis lato lanceolatis utrinque vix angustatis sessilibus; capitulis 12-30-floris corymbosis paucis majusculis (5-6 lin. longis); receptaculo elevato paleis pluribus onusto; corollæ tubo pappi paleas lanceolatas margine eroso-denticulatas superante, fauce vix ampliata, limbo 5-partito. — Kauai, Sandwich Islands.

ARGYROXIPHIUM and WILKESIA. The characters of the latter genus, and of a new species of Argyroxiphium, with the announcement that this had a circle of paleæ at the margin of the receptacle, epappose ray-achenia enclosed in the involute subtending scales of the involucre, and therefore belonged to the Madieæ, - were published by me, in the Proceedings of the Academy (Vol. II. p. 160), a dozen years ago. These notes appear to have escaped attention. Having now further to add that the paleæ of Argyroxiphium are concreted into a cup, in the manner of several Madieæ, so that, indeed, Wilkesia may be viewed as an Argyroxiphium with the ray-flowers and the subtending involucre suppressed, it is worth while to reproduce the characters with emendations.

Involucrum uniseriale, squamis numerosis (tot quot ligula) discum subæquantibus angustis convolutis achenia radii involventibus.

ABROTANELLA (CERATELLA) SUBMARGINATA (sp. nov.): pulvinatocæspitosa; foliis crebris linearibus e basi erecta patentibus sursum leviter calloso-marginatis truncato-obtusis vel retusis; capitulis solitariis subsessilibus paucifloris; involucri squamis subuninerviis; acheniis obsolete 3-4-nervatis angulatisve inferne hirtellis pappo coroniformi et pauciaristulato vel dentato superatis. - Orange Harbor, Fuegia. In foliage nearly intermediate between A. emarginata and the following species, in general appearance very like A. (Ceratella, Hook. f.) rosulata, but the leaves smaller and narrower. Heads and flowers nearly as in A. emarginata, but with a rather conspicuous pappus, consisting of a thin and scarious coronula, two to four teeth of which are commonly extended into short awns. Nothing is less reliable, at least generically, than distinctions founded upon the presence, degree of development, or absence of a paleaceous, coroniform, or other reduced kind of pappus. Dr. Hooker will not be surprised that this and the following species demand the reduction of his Ceratella, Trineuron, and therefore Scleroleima, to Abrotanella.

ABROTANELLA (CERATELLA) LINEARIFOLIA (sp. nov.): laxe cæspitosa; foliis linearibus seu lineari-subspathulatis immarginatis patulis, supremis capitulum pedunculatum adæquantibus; involucri squamis ovalibus sub-2-3-nervatis ; floribus foemineis 2-3, hermaphroditis 6-8 stylo pl. m. bifido, omnibus sæpissime fertilibus; acheniis glaberrimis elongato-obovatis 4-costatis apice subcontractis pappo obscure cupulato truncato nunc sub-4-dentato nunc plane 4-aristulato superatis. -Orange Harbor, Fuegia. With the aspect and foliage (although on a rather smaller scale) of A. spathulata (Trineuron, Hook. f.) this has the floral characters of A. (Ceratella) rosulata, except that the flowers are all fertile; and as to the pappus, it is intermediate between Ceratella and Scleroleima.

LUCILIA, Cass., remanded to the Gnaphaliea by Remy, and rightly described as to the pappus by Weddell, ought to include Belloa, too slightly distinguished by the papillose instead of silky achenia, as is Merope, by the at length spreading, instead of connivent, scales of the involucre. In some specimens they appear neither to spread nor to connive. Nuttall's Gnaphalium depressum, described from Pichincha specimens of Professor Jameson's collection (no. 642 and 57) is not the G. radians, Benth. i. e. L. (Merope) Kunthiana, but apparently the L. conoidea, Wedd., or near it, although larger. L. gnaphalioides, Less. includes L. argentea, Hook. & Arn., in which, by a typographical error of the Prodromus, the heads are said to be three-flowered in place of thirty-flowered.

LUCILIA (MEROPE) PIPTOLEPIs, Wedd., a form with more caulescent sterile shoots from the Peruvian Andes.
