NEW OR NOTEWORTHY CHROMOSOME RECORDS IN THE ANGIOSPERMS', PETER GOLDBLATT3 ABSTRACT The following chromosome numbers are reported: Miersia chilensis 2n = 20, Gethyum atropurpureum 2n = 14 (Alliaceae); Aextoxicon punctatum 2n = 32 (Aextoxicaceae); Nymania capensis 2n = ca. 48 (Aitoniaceae); Ilex pedunculosa 2n = 120 ( Aquifoliaceae ); Oroxylon indicum 2n = 38, Millingtonia hortensis 2n = 30 (Bignoniaceae); Canella alba 2n = 28 (Canellaceae); Cneorum tricoccum 2n = 36 (Cneoraceae); Eucryphia lucida 2n = 30 (Eu-cryphiaceae) ; Greyia sutherlandii 2n = 32-34, n -ca. 17 (Greyiaceae); Koeberlinia spinosa 2n = ca. 88 (Koeberliniaceae); Erythrina burttii 2n -ca. 168 (Leguminosae); Rhynchocalyx lawsonioides 2n = 20 (Lythraceae); Montinia carylophyllacea n = 34, 2n = 68 (Montinia-ceae); Olinia emarginata 2n = ca. 40(-42), 0. radiata -= ca. 30(-28) (Oliniaceae); Oftia africana 2n = 38, n -ca. 19 (Scrophulariaceae). A survey of cytology and evolution in the Angiosperms by Raven (1975) has brought to attention many examples of groups that are unknown cytologically. Numerous gaps exist both at the family level and amongst phylogenetically criti-cal subfamilies and genera. The present paper, in which the cytology of several rare or critical taxa is reported, represents a contribution to our knowledge of some of these groups. Of the 22 collections, representing 18 taxa studied here, 11 are believed tobe the first reports for the following families: Montiniaceae and Oliniaceae, andif the following are recognized, Aextoxicaceae, Aitoniaceae, Eucryphiaceae,Greyiaceae, Koeberliniaceae and Oftiaceae. In addition to the genera in thesefamilies (Montinia, Olinia, Aextoxicon, Niymania, Eucryphia, Greyia, Koeberlinia,and Oftia), the present report also includes first records for the following genera:Canella (Canellaceae), Gethyum (Alliaceae), and Rhynchocalyx (Lythraceae).Previous reports for Cneorum (Cneoraceae), Oroxylon, and Millingtonia (Big-noniaceae) are substantiated while high polyploidy in species of Ilex (Aqui-foliaceae) and Erythrina (Leguminosae) is confirmed. 'I wish to thank P. H. Raven, Director, Missouri Botanical Garden, St. Louis, for hisguidance and encouragement in this project. Thanks are also extended to the following fortheir help in providing the plant material used in the study: G. L. Stebbins, Department ofGenetics, University of California, Davis, for bulbs of species of Gilliesieae; B. Bartholomew,Department of Botany, University of California, Berkeley, for Aextoxican punctatum; C. W.Campbell, Food and Agricultural Sciences Institute, University of Florida, Homestead, forCanella alba and Oroxylon indicum; V. D. Roth, Southwestern Research Station, AmericanMuseum of Natural History, Portal, Arizona, for Koeberlinia spinosa; R. G. Strey, Natal Her-barium, Durban, South Africa, for Rhynchocalyx lawsonioides; J. P. Rourke, Curator, ComptonHerbarium, Kirstenbosch, South Africa, for Oftia africana; D. A. Ratkowsky, C.S.I.R.O., Tas-mania, Australia, for Eucryphia lucida. Cytological material of Olinia cymosa, Greyia suther-landii, and the second collection of Oftia africana was provided by P. H. Raven. SCounts for Olinia radiata, Oftia africana and Greyia sutherlandii were made by A. M.Powell, Department of Botany, Sul Ross University, Alpine, Texas. : B. A.
