ARTICLES IN JOURNALS. 485 There is, we think, no better method of illustrating plants, from the botanist's point of view, than that generally followed here. The whole thing is sketched out in black and white, while the colour is indicated in the flower and its dissections and a por- tion only of the chief figure. The floral dissections are numerous, and have every appearance of accuracy. We would, however, suggest that ink-lines are better adapted for these details ; chalk is admirable for the general sketch of the habit, but the sharper ink- line obviates any chance of confusion in the sometimes very com- plicated parts. The second portion of the book contains Plates 51 to 100, as well as the title-page, table of contents, and index to the whole volume. From the systematic table we find that 101 species and varieties have been figured. The tribe EpidendrecB are repre- sented by Liparis and a Bulbophyllum ; Vandece by EiilopJiia, Angr cecum y and Mystacidium ; NeottiecB by Zeuxine, Platylepis, and Pogonia; occupying in all twenty plates. The rest are devoted to the OphrydecBj by far the richest tribe in South Africa ; they include fourteen species and one variety of Satyrium, twenty-two species of Visa, and nine of Disperis. A considerable number are Mr. Bolus's own introductions to science, while several are accredited to Mr. Schlechter. Apropos of the latter, we notice a form of quotation which is likely to lead to confusion in the future, and to which, from past experience, we think it well to call attention. Several of Mr. Schlechter' s species are referred to in **Engler's Botanische Jahr- biicher, ined." As Mr. Bolus supplies a full description, a subsequent, description in Engler's Jahrbiicher is rendered unnecessary, and the species must at any rate always be quoted from the work now before us. If, however. Prof. Engler does admit them into his journal, we hope he will see that they are not again labelled n. sp." We call to mind a paper by Dr. Kranzlin, entitled *' Orchidaceae Afri- canae II.," which appeared in the Botanische Jahrbiicher, Bd. xxii. Of twenty-eight new species" therein described, nineteen had already been published (with descriptions) in Part C of the Pflanzen- welt Ost-Afrikas. As Prof. Engler is editor of both these works, it seems to us that he was in a position to know the date at which each would be published, and a reference should have been made in the latter to the former publication.
