THE present section of Volume V. completes the description of the MonocotyLepons of South Africa to which Volumes VI. and VII. are devoted. Its preparation has been long postponed in the hope that the Orchidew might be undertaken by Dr. Botus who had made a continuous study of the South African species from 1882 to the close of his life thirty years later. No botanist has ever succeeded in examining or in illustrating with his own hand so many of them in a living state. The “Icones Orchidearum Austro-Africanarum Extratropi- carum” in two volumes, commenced in 1892, and the revision of the last proof-sheets of which occupied him “on the very eve of his death” on May 25th, 1911, are a worthy and permanent monument of his labours. Failing health had compelled him to abandon the elaboration of the Ericacew beyond the vast genus Erica, in which the late Professor GuTHRIE had collaborated with him, and it equally deterred him from attempting the study of the intricate problems which are involved in the synonymy of so many of the imperfectly described species of South African Orchideer.

In the event I was reluctantly compelled to acquiesce, and I entrusted their elaboration to Mr. R. A. Rotre, A.L.S., Assistant in the Herbarium of the Royal Botanic Gardens, Kew, who has long made the order his special study, and had previously contributed the Orchidew to the seventh volume of the Flora of _ Tropical Africa.”

I am indebted for much friendly aid to Lieut.-Colonel-Sir Davw Prat, C.M.G., C.LE., F.R.S., Director of the Royal Botanic Gardens, and my acknowledgments are also due to Mr. C. H. Waricut, A.LS., and to Mr. N. E. Browy, A.LS.,



Assistant Keepers of the Herbarium, the former for reading the proofs and the latter for working out the localities and geographical distribution.

For the limits of the regions under which the localities are cited in which the species have been found to occur, reference may be made to the Preface to Volume VI.

Besides the maps already cited in the Preface to Volumes VI. and VIL, the following have also been used :—Map of the Colony of the Cape of Good Hope and neighbouring territories. Compiled from the best available information. By Joun TEMPLER Hornek, Surveyor-General, 1895. Stanford’s map of the Orange Free State and the Southern parts of the South African Republic, etc., 1899. Carte du Théatre de la Guerre Sud-Africaine. Par le Comte CAMILLE Favre, 1902.

A correct determination of the species represented by the names and descriptions of earlier writers is a necessary basis for an accurate nomenclature. With this object, in order to assist Dr. Bo.us and to the ultimate advantage of the Flora, the types of South African Orchids described by THUNBERG were generously entrusted to Kew in 1883 by Dr. Tu. M. Frtss, the Director at the time of the Botanic Garden at Upsala, and in the following year the same kind service was rendered for those of Swartz by Dr. V. B. Wirrrock, Director of the Museum of Natural History at Stoekholm. They were critically examined by Mr. N. E. Brown and compared with the specimens of LINDLEY preserved at Kew. Errors in the correlation of the names of the earlier with those of later botanists were detected by him and communicated to Dr. Borus as well as to Mr. Rorr.

Further acknowledgments for the loan of types are due to :—

Dr. J. 1. Briguet, Director of the Botanic Gardens, Geneva ;

Geheimrath Dr. A. ENGLER, Director of the Botanic Garden,

Dahlem ; Professor C. A. M. LinpMAN, Curator of the Botanical Department of the Museum of Natural History, Stockholm; and for the same service, as well as for the gift of specimens,

Dr. RuDOLPH ScHLECHTER, Berlin. The general material worked out is due toa long series of


contributors of specimens of South African plants whose names are recorded in the previously published volumes.

The expenses of preparation and publication of the present section have been aided by a grant from the Government of the Transvaal. W. TT. ToD: Witcompr, 20th February, 1913.
