The following are not officinal in the British Pharmacopœia:--page 316, _Dracæna_ (Dragon’s-blood), _Smilax glabra_; p. 321, “Orris-root”; p. 326, species of _Curcuma_, _Alpinia officinarum_; p. 333, _Orchis_-species (“Salep”). On page 296, par. 4, only Pearl Barley is offic. in the Brit. Phar. CLASSIFICATION OF THE VEGETABLE KINGDOM. The Vegetable Kingdom is arranged in 5 Divisions. Division I.--=Thallophyta=, =Stemless Plants=, or those which are composed of a “thallus,” _i.e._ organs of nourishment which are not differentiated into root (in the sense in which this term is used among the higher plants), stem, or leaf. Vascular bundles are wanting. Conjugation and fertilisation in various ways; among most of the Fungi only vegetative multiplication. In contradistinction to the Thallophytes all other plants are called “Stem-plants” (“Cormophyta”), because their shoots are leaf-bearing stems. The name Thallophyta (Stemless-plants) is to some extent unsuitable, since many of the higher Algæ are differentiated into stem and leaf. The Thallophytes are again separated into 3 sub-divisions, namely: Sub-Division =A.=--=Myxomycetes, Slime-Fungi=, with only 1 class. Sub-Division =B.=--=Algæ=, with 10 classes: Class 1. Syngeneticæ. „ 2. Dinoflagellata, Peridinea. „ 3. Diatomeæ, Diatoms. „ 4. Schizophyta, Fission Algæ. „ 5. Conjugatæ. „ 6. Chlorophyceæ, Green Algæ. „ 7. Characeæ, Stone-worts. „ 8. Phæophyceæ, Brown Algæ. „ 9. Dictyotales. „ 10. Rhodophyceæ, Red Algæ. Sub-Division =C.=--=Fungi=, with 3 classes: Class 1. Phycomycetes. „ 2. Mesomycetes. „ 3. Mycomycetes, Higher Fungi. Division II.--=Bryophyta or Muscineæ, Mosses.= These have leaf-bearing shoots, but neither true roots nor vascular bundles. The lowest Mosses have, however, a thallus. Fertilisation is accomplished by means of self-motile, spirally coiled spermatozoids, through the agency of water. From the fertilised oosphere a “fruit-body” (capsule) with unicellular organs of reproduction (spores) is produced. The spore on germination gives rise to the vegetative system, which bears the organs of sexual reproduction; and this system is divided into two stages--the protonema, and the leaf-bearing plant produced on it. Alternation of generations: I. The protonema and the entire nutritive system which bears the organs of sexual reproduction. II. The capsule-like sporangium, with spores. 2 Classes: 1. Hepaticæ, Liverworts. 2. Musci, Leafy Mosses.
