vegetable sulphur

From The Collaborative International Dictionary of English v.0.48:

Sulphur \Sul"phur\, n. [L., better sulfur: cf. F. soufre.]
   1. (Chem.) A nonmetallic element occurring naturally in large
      quantities, either combined as in the sulphides (as
      pyrites) and sulphates (as gypsum), or native in volcanic
      regions, in vast beds mixed with gypsum and various earthy
      materials, from which it is melted out. Symbol S. Atomic
      weight 32. The specific gravity of ordinary octohedral
      sulphur is 2.05; of prismatic sulphur, 1.96.
      [1913 Webster]

   Note: It is purified by distillation, and is obtained as a
         lemon-yellow powder (by sublimation), called flour, or
         flowers, of sulphur, or in cast sticks called roll
         sulphur, or brimstone. It burns with a blue flame and a
         peculiar suffocating odor. It is an ingredient of
         gunpowder, is used on friction matches, and in medicine
         (as a laxative and insecticide), but its chief use is
         in the manufacture of sulphuric acid. Sulphur can be
         obtained in two crystalline modifications, in
         orthorhombic octahedra, or in monoclinic prisms, the
         former of which is the more stable at ordinary
         temperatures. Sulphur is the type, in its chemical
         relations, of a group of elements, including selenium
         and tellurium, called collectively the sulphur group,
         or family. In many respects sulphur resembles oxygen.
         [1913 Webster]

   2. (Zool.) Any one of numerous species of yellow or orange
      butterflies of the subfamily Pierinae; as, the clouded

      which is the common yellow butterfly of the Eastern United
      [1913 Webster]

   Amorphous sulphur (Chem.), an elastic variety of sulphur of
      a resinous appearance, obtained by pouring melted sulphur

      also sulphurous anhydride, and formerly {sulphurous

      agent. Called also sulphuric anhydride, and formerly
      sulphuric acid.

   Vegetable kingdom (Nat. Hist.), that primary division of
      living things which includes all plants. The classes of
      the vegetable kingdom have been grouped differently by
      various botanists. The following is one of the best of the
      many arrangements of the principal subdivisions.
      [1913 Webster] I. Phaenogamia (called also
      Phanerogamia). Plants having distinct flowers and true
      seeds. [ 1. Dicotyledons (called also Exogens). --
      Seeds with two or more cotyledons. Stems with the pith,
      woody fiber, and bark concentrically arranged. Divided
      into two subclasses: Angiosperms, having the woody fiber
      interspersed with dotted or annular ducts, and the seeds
      contained in a true ovary; Gymnosperms, having few or no
      ducts in the woody fiber, and the seeds naked. 2.
      Monocotyledons (called also Endogens). -- Seeds with
      single cotyledon. Stems with slender bundles of woody
      fiber not concentrically arranged, and with no true bark.]
      [1913 Webster] II. Cryptogamia. Plants without true
      flowers, and reproduced by minute spores of various kinds,
      or by simple cell division. [ 1. Acrogens. -- Plants
      usually with distinct stems and leaves, existing in two
      alternate conditions, one of which is nonsexual and
      sporophoric, the other sexual and oophoric. Divided into
      Vascular Acrogens, or Pteridophyta, having the
      sporophoric plant conspicuous and consisting partly of
      vascular tissue, as in Ferns, Lycopods, and Equiseta, and
      Cellular Acrogens, or Bryophyta, having the sexual
      plant most conspicuous, but destitute of vascular tissue,
      as in Mosses and Scale Mosses. 2. Thallogens. -- Plants
      without distinct stem and leaves, consisting of a simple
      or branched mass of cellular tissue, or reduced to a
      single cell. Reproduction effected variously. Divided into
      Algae, which contain chlorophyll or its equivalent, and
      which live upon air and water, and Fungi, which contain
      no chlorophyll, and live on organic matter. (Lichens are
      now believed to be fungi parasitic on included algae.]
      [1913 Webster]

   Note: Many botanists divide the Phaenogamia primarily into
         Gymnosperms and Angiosperms, and the latter into
         Dicotyledons and Monocotyledons. Others consider
         Pteridophyta and Bryophyta to be separate classes.
         Thallogens are variously divided by different writers,
         and the places for diatoms, slime molds, and stoneworts
         are altogether uncertain.
