THE KNOWN GEOGRAPHIC DISTRIBUTION OF THE MEMBERS OP THE VBR-BSNACSAE AND ATICENNIACSAS ^ SUPPLEMENT 6 Harold N. Moldenka Continued studiee of herbarium material of the Avioennia-ceae, Symphoremaceae , Stllbaoeae, and Verbenaceae have brought to light 481 new country or island records in these groups, 445 new state, province, or department records, and 222 new county or parish records not previously recorded by me in my tabulation of the known geographic distribution of the accepted members of these groups [Moldenke, H. N., The known geographic distribution of the members of the Verbena-ceae and Avicenniaceae , 104 pp. 1942; Supplement 1, 4 pp. 1945; Supplement 2, in Bot. Gaz. 106 1 158—164. 1944; Sup-plement 5, in Castanea 10: ^5 — 46. 1945; Supplement 4, in Am. Joum. Bot. 52: 609—612. 1945; Supplement 5, in Bol. Soc. Venez. Cienc. Nat. (in press)]. The specimens on which these records are based will all be cited in my forthcoming monographs of the genera involved, or in the supplements thereto, but as it will probably be some years before these generic monographs are all published, it has been thought advisable to make the specific and varietal records avail-able to students working on the flora of given areas. The 7,000 herbarium specimens on which these new records are based are deposited in the herbaria of the New York Botani-cal Garden, Missouri Botanical Garden, United States Natio-nal Museum, Cornell University, New York State Museum, Uni-versity of Texas, L. H. Bailey Hortorium, Jardin Botanique de I'Etat at Brussels, Museo de Historia Natural at Monte-video, University of Miami, Chicago Natural History Museum, Gray Herbarium of Harvard University, Botaniska Tradgard at Goteborg, Museo Paranaense at Ouritiba, Universidad N&cional de Mexico at Mexico City, Instituto Miguel Lillo at Tucuman, Princeton University, Jardin Botanico at Madrid, Naturhist-oriska Riksmuseum at Stockholm, Instituto Darwinion at San Isidro, Southern Methodist University, Vanderbilt Univer-sity, and the private herbaria of Harry Ahles, Jose Eugenio Leite, C. L. Lundell, and Mary Thais, As in previous installments of these records, an asterisk (*) following a name indicates that the plant is endemic to that country or island, as far as now known.
